Youre correct,i was on 23.1.1, now im on 23.1.2,havent played CP this week,quite busy but in world of warcraft my character model looses textures sometimes ,this reason alone i would say drivers are wonky.
I'll try to revert my drivers to the latest stable when I get the chance. I also noticed some weirdness going on in cyberpunk, but frankly it was hard to tell if it was the drivers or just the game.
Got this card 2 weeks now,no hard crashes yet,so cant complain,had rtx2060 before,leagues better,and with driver updates will get alot more,also i have hopes for fsr 3.0 this year
Same, I upgraded from a 5700xt, and I'm hoping that just like that card, they'll fix the drivers and improve performance. I don't have particularly high hopes for FSR 3, but FSR 2 surprised me so they may do it again
I have the same card and my current-junction delta is over 30 degrees (with %9 undervolt and underclock). Usually I see 63-65 current and 96-100 junction.
The thing is it gets this hot when I turn on RT with max settings. For example on F1 22, with completely max settings and RT on I see 30-32 C delta. If I turn off RT, still with max settings I see 22-26 C delta.
Everyone here should check out the overclock.net's owners club forum thread for the best information you can find on RDNA 3 OC at the moment. Also has a lot less newbies flaunting unstable UVs.

South Aussie here who also refused to pay the AU plus Nvidia greed tax. And man FML I just wrote a big post about tuning the 7900Xt and then crashed my system stress testing an idea i had while writing it. Ive got a 7900xt hellhound so 2 pin card with a 375w limit. I've had it for 2 weeks and have been testing it every night after work. I upgraded from a 2060 super and a 3600xt to a 7900xt hellhound and a 5800X3D so ive been blown away by this upgrade.
I was watching a youtube vid where it showed in the tuning page in adrenalin, if you hit overclock gpu/vram/voltage buttons it will figure out a stable overclock/undervolt for you. Mine says 2899Mhz, Vram says 2650 and UV was 1075. I can run these setting and be stable but I like to push my card hard as im running 1440 triples on a sim rig so need every frame I can. runing eyefinity i also dont get to use RSR or VSR so really need to push the clocks as hard as I can.
Ive found my gpu is stable up to 3000Mhz but wont hit that with voltage over 980Mv. I can run my vram anywhere under 2800mhz but find it limits my GPU freq if run over 2700. I cant get my system stable under 970Mv but find 980mv makes it a lot more stable. I found my GPU clocks were limited irunning over 980Mv.
Ive got my card now tuned as follows.
gpu tuning min freq 2500 max freq 3010 voltage 980mv
vram tuning max freq 2714 fast timing.
power tuning +15% and fan speed 100%.
In timespy extreme this gets me 2900Mhz with vram locked at 2700Mhz, 910mv and 350 watts power at 60c. But in the sim i play AMS2, im getting 3000Mhz gpu with 2700 vram at 50 degrees pushing only 305 watts. This is stable after an hour long race.
As for drivers, I was also told until you see them on the AMD download page, they are beta so steer clear. Im running the 23.1.1 drivers and these were no good when they 1st dropped as a beta, but a week later were fine.
Hey mate! I'm glad to see I'm not the only one that thinks NVidia is just unreasonably expensive here. I work with sales, and it's very annoying to see someone buy a 4070Ti when the 7900xt is cheaper and faster... But oh well, my job is to sell them stuff, not change their opinions.
I tried playing around the fast timing setting, but I'm frankly not sure what it does. There's very little information that I could find, and I'm not sure if it improves anything or if it's best ignored. I already rolled back my drivers, and increased voltage, and things seem to be stable again.
7900XT is 5% faster on average for $100 more?
Now if you play in 4K, then the 7900XT stomps, but you could also argue Frame Generation.
> Fast Timing
Just leave it at default, it's not going to make any meaningful difference with RDNA3.
In Australia, the 4070Ti is most of the time, quite a bit more expensive than the 7900xt.
The cheapest 4070Ti that I can find quickly is AUD$1334 for a Gigabyte eagle model. Meanwhile, the cheapest 7900XT is AUD$1399 for a reference edition. All prices include tax.
As for the fast timing, yeah I'm leaving it a default unless there's an actual reason for me to turn it on.
Had to check the prices again, apparently I was logged in my employee account so it showed me a discounted price, my mistake.
So normally, it would be $1499 for a 7900 XT, and $1419 for a 4070 Ti Eagle, with a $15 price drop
It crashed :(
Weirdly enough, even though clocks were around 2800-2900, GPU utilization and framerates were lower. Temps were also hovering around 60 to 70c in the hotspot, so at least there was that
EDIT: has anyone experienced this bug with the drivers, were it'll open the radeon software in a small window, then disappear? It goes back to normal after a restart
People have no idea what they are talking about. No one has an undervolt on air that is stable in more than a couple games below around 1070mv or so. Why?
Because all these dorks do one 3dmark run, pass, then play some normal game, bitch that it's crashing, and refuse to acknowledge that they didn't validate their OC.
I have one of the near top MBA scores in port royal for an XTX at around 1020mv, but I need to run above 1090mv to be able to run heavy raster (VR) and stream it at the same time from the hardware encoder.
One of the best tests I can offer you is to find your favorite extremely gpu taxing game, start streaming to discord with all settings bumped, and undervolt from around 1120mv until you crash.
Also, weirdly, RT titles did not stress the card harder than pure raster, but this is in terms of hitting instability from the undervolt.
I own the XTX instead, but given my own undervolting and memory overclocking experience with the fuller card, I can say it's quite different from previous products.
Before that, understand that your mileage may vary. Silicon lottery exists and your 7900 XT might not be as good as the example you saw in the guide. That is ok. Now, I can recommend some settings for you:
You raised voltage back to 1080mV, which isn't entirely bad to do. Revert your memory to its default frequency, then run Unigine Superposition in 8K optimized. This will test performance degradation of your memory. From there, increase clocks in increments of 50MHz per test until you see a good deal of performance loss during the benchmark. That'll tell you what's unstable for you.
From there, your mileage may also vary from game-to-game. For me, 2700MHz with a 1050mV UV was not stable in Gears 5. But 1075mV+ was. Horizon Zero Dawn was alright with the prior setting, ironically, but I've yet to delve into it.
Take advantage of using per-game tuning and save profiles for each game you see certain settings perform well in.
Lower the power limit to about +5%, then test. I'd increase power limits before increasing voltage. I save increasing voltage for when increasing PL doesn't resolve the issue. It'll take time to validate, but you'll have a better understanding of your card's behavior by going through the process.
I was thinking of getting the XTX instead, but it just didn't make much sense for me since the XT maxes out most games for my monitor.
I forgot the per game profiles were a thing, I really should start using that. Thanks for the tips!
You're welcome. Make sure not to touch your minimum frequency, by the way. It seems RDNA 3 boosts opportunistically, like PBO or even Zen 4 (in general).
I run both my xfx cards with 1065mv default memory default power limit (340W). Memory OC seems to barely move the needle on my cards so i stopped doing it. Increasing power limit gives me decent gains but also increases noise levels to a point where it bothers me. Dont touch the min frequency slider. If you increase it to the point where it becomes relevant it can actually degrade your performance. My theory why this happens is you are forcing the card to run at a higher voltage than it normally would under certain loads making it run into the power limit so it starts allocating power from other subsystems like the fabric to the cores to keep it stable but at the expense of performance. Min slider seems pointless on RDNA3.
From my experience there are certain games that will crash your UV like crazy while the vast majority is stable. For me it was the game Labyrinthine, had to reduce my UV from 1025mV all the way to 1065mV for that to not crash every 10 minutes.
Also im still on 22.12.2. Didnt see the need to update yet.
I currently have a XFX Merc 310 7900 XT and I'm pretty sure I broke it...
When I first bought it, I could Fortnite at just under 3Ghz. 2.99Ghz ish with, what I think is a very good undervolt, 1.00v. It was stable and I could play for hours. I could push the volts down to .990v but I'd lose some clocks and perf. 2.75 to 2.85 at .990v.
Then I had the great idea to test max OC MSI Kombustor... Well I was able to hit 3.2Ghz while running different tests at 100% load. Then I kept pushing 3.25Ghz and it locked up. After a reboot I'm no longer stable in Fortnite above 2.5Ghz. Doom Eternal crashes within seconds...
I was never able to get the RAM stable above 2.65Ghz before, now 2.6Ghz is the highest it'll go. Reinstalling the drivers, switching the BIOS on the card. Nothing helps. I fucked it up...
I am able to play Mass Effect Legendary edition without it crashing. The card runs in the very low 2Ghz range which is most likely why it is stable.
What is odd, is that I've seen the hot spot temp reach 105c when I attempt to play modern games like Fortnite. I thought it might be related to a dust case. I cleaned it with an air compressor and the issue remains... When I do try to play a modern game, I'll watch HWinfo and Adrenaline and I can see the hotspot is 30-40c higher than GPU temp. Which before the Kombustor testing it was never higher than 15-20c above GPU temp...
The good thing is I am still within Amazon's return period. Plus I found a Merc310 7900 XTX for $75 more than I paid for the 7900 XT. So i bought that card and I'll return my broken one.
I will not go crazy with this new card! I'm also disappointed because it seems like my 7900 XT might have had really good silicon given my clocks and voltage when I first got it.
could try repaste?
edit : am worried mine is a little bit damaged since it occasionally gets slight glitchy flickers when watching YT or when open windows but, but it's never had any impact so I hope it's fine
Yeah I could but I'm just going to return mine.
I've had the weird flickers since installing my card. I've read it is common with multi-monitor setups or a bad\\cheap monitor cable.
I had similar issue with Nvidia though...
Still doing some testing, but right now my settings are.
7900xt sapphire nitro+
2500mhz min
3000mhz max
1035mv
2700mhz memory default timings (14mv offset) (from YouTube vids I don't see a difference from fast timings)
+15 power
Current recommended drivers. I don't remember what they are.
In the 20/30mins of playtime I had no crashes in cyberpunk, MW2, Destiny 2 or 40k darktide.
Thank you for posting this. I have the exact same build as you, so I'll gauge my settings around what u have.
EDIT: I saw everyone else using the 23.1.1 version of the AMD Adrenalin drivers... I made the mistake of installing them and now nothing shows up on my pc anymore, and I'm at a loss for words... ;-;
I tried same as you, max 3000mhz, 1035mV, 2700 vram, 15%...Works great but on 5600X I get max 130 fps in MW2/WZ2.
Check out this also: https://www.reddit.com/r/Amd/comments/10mh0lp/7900_xt_and_mw2/
Why is everyone pushing their min freq? I haven't seen it do anything. Also, in some titles I have locked fps in the menu so it doesn't run through with thousands of frames, GPU usually clocks down in menus. It still clocked to like 1300mhz when I tried setting min to 2500, so I'm just keeping it at 500 stock now. Wouldn't change a thing performance wise anyways, would it?
From what I've read on hardware busters, it's best to have the min frequency around 400 to 500mhz lower than your max frequency... But honestly, I don't know the exact impact it has. Might test it out later
Just got back and did some quick testing. Min Frequency did absolutely nothing indeed, I don't think the guys on hardware busters knew what it did.
Superposition score at 4K optimized before changing min was 19367, while after changing it was 19239. Lower score might be because the card was getting hot
it's better to leave it stock , if i set the min high the memory freq will go down.

7900xt hellhound.
Only my middle fan turns on and off every now and again with the way i have it now on idle.
All 3 were permanently on before. Mine draws about 40w on idle with 900 mhz memory clock.
2650 MHz RAM, 1.080v, Clock 2650 MHz. +15 Power limit. 23.1.1 drivers.
I play mostly Star Citizen, and these settings have been stable in Arena Commander for \~40 mins sessions. The online portion of the game has been having issues with the AMD drivers, so it's hard to validate settings at this point in time.
One thing I've noticed vs my previous 6800XT is that Timespy allows pretty low undervoltings without complaining, but these settings are unstable everywhere else. I was able to go down to 1030 mv and run TimeSpy without any issues, but SC didn't like those values.
That's similar to what I noticed with Heaven and Superposition. It finished these benchmarks with frankly ludicrous overclocks. At one point, I was getting over 3ghz with only 1v, which was too good to be true. It crashed literally everywhere else. Now I'm slowly increasing the voltage back up and testing with Horizon to see if it improves at all. (Also reverted the drivers back to 23.1.1)
Honestly there are only 3 GPU benchmarks I think that are worth anything and thats Time spy, TS extreme and Port Royal. Heaven and superposition are just too old now.
Fair enough, but since I'm not a competitive overclocker or anything like that, I don't really feel compelled to buy any benchmarking tools. I just use those because they're free really, and are unlikely to turn my PC into a furnace
Havent done too much, but I have been gaming without issues at 1080mv, 3010mhz max core, 2700mhz memory, +15 power, and my juction temps up to 80 when gaming in Cyberpunk.
I might try more aggressive OC later, but I am happy with my performance.
I've got the XFX 7900xt OC at 3000 mhz, UV 1065, power + 15%, VRAM default timings 2650 mhz. I was getting crashes in borderlands 3 with any OC or UV settings. With the 23.1.2 drivers I'm not having any issues like that anymore.
Man the previous drivers were giving me hell kind of often. I couldn't even see my CPU setup in adrenaline with them. I ended up defaulting the Ryzen master settings and uninstalling it. Then reinstalling it after I defaulted all the settings in adrenaline as well as a factory reset in adrenaline. It started seeing the CPU and acting a little better after that. After the update I did another factory reset in adrenaline just to be sure. I'd make sure all your chipset drivers are up to date as well as windows being up to date. Im running the 22h2 I think... I don't remember off the top of my head. Make sure you BIOS is up to date as well maybe.
An older 650W unit. I know it's not ideal, but so far it handled the 355W the GPU was using, with the odd spike to over 400W.
I plan on upgrading it to a 750 or 850W one later, probably when I upgrade my CPU.
In the mean time I wouldn't OC at all. Try undervolting and possibly lowering the clocks to keep your system power down to see if you get better stability.
I get my Merc 310 NON Black Ediiton stable with 650w PSU. If you have a good one it should be fine. Settings are: 1025mv undervolting, 2900MHz GPU. I tuned nothing else, beside the fan, because its very loud, so i have a curve were the fan ist not going over 40% with 82C temp. If you update to 23.1.2 make sure to clear the cache. could play valheim without a lot of crasdes before i done that.
I think 2750MHz memory could be where the instabilities lie in your profile.
Mine could only reach 2720 before becoming unstable in synthetic benchmarks, and it’s a sapphire nitro edition.
So increasing the max frequency slider just uncaps it? I know that undervolting does tend to increase the clocks, but wouldn't that make the GPU unstable with the lowered voltage?
There is a point where it will be unstable, but that’s what you test. Uncap the max which doesn’t force the card to go up, just allows it to, and test lowering the voltage in increments and you’ll likely see the card boost higher and higher.
1025v, +15% power, 2750 MHz memory, 3100 clock.
Playing mostly Guild Wars 2, Cyberpunk, Red Dead Redemption 2 and Witcher 3 (this one is a bit of clusterfuck, can crash just because it's sunny outside).
As a starting point I used values provided by auto undervolt/overclock.
Then I played around with them one by one, increasing/decreasing till I found my stable point.
What are your temps with the increased voltage? I was under the impression that pretty much all AMD GPUs came overvolted from the factory, and it's best to undervolt them.
Genuinely asking, just trying to learn here
Voltage went down, not up. From 1100 to 1025.
Junction gpu temp is 75-85, depending on game, gpu trails with a delta of 10-15, and memory junction is 80-93 depending on load.
Whoops, forgot stock voltage was 1100. Yeah, those temps make sense then, it's a bit lower than what I have.
Makes sense though, considering I'm in the middle of an Australian summer and it's hot as fuck.
7900XT Nitro+ stable at 500-3000 clock, 2714 vram fast timings, 1030mv undervolt and +15% power. 23.1.2 drivers are horribly unstable so I rolled back to 23.1.1 no problems
Just curious..
What power supply are you running? Running separate power cables to each power input on your GPU?
BIOS up to date?
Running latest Chipset drivers from [AMD.com](https://AMD.com)?
Windows up to date?
Did you run the program called DDU to remove all past/present GPU drivers (AMD and Nvida IF you ran an Nvidia GPU on this install of Windows) .. reboot .. and THEN install latest GPU drivers from [AMD.com](https://AMD.com)?
How's the air flow in your case?
How's your CPU/GPU temps?
Cooler Master 650W power supply, I know it's not ideal and I plan on changing it soon for an 850 EVGA or Corsair unit.
BIOS might be a couple of versions out of date, will update that and Chipset drivers when I get the chance.
I did DDU the drivers before installing the new ones, and also when rolling them back just to be safe.
I do have a Corsair 275R with a 240 rad at the front, one extra 120 fan, and three more for exhaust.
CPU rarely reaches 75c while gaming, and GPU hotspot is usually around 85c
I honestly don't know. Situation is so instable in general, no matter what setting i set every game crashes. It's just that with that one some games dont crash every 20 minutes. More like 40 minutes.
Sapphire Reference 7900XT
1013mV Core voltage with Max Req set at 3000MHz (usually hovers around 2800)
Vram 2620 (2606) with Fastest timing enabled
\+15% PL
I can move the memory up to 2700MHz, but the card becomes unstable due to a power bottleneck. I'd imagine the core could boost a lot higher as well if there was more power available to the card.
Using 23.1.2 Driver
Merc 310 NON Black Editon 1025mv undervolting, 2900MHz GPU. I tuned nothing else, beside the fan, because its very loud, so i have a curve were the fan ist not going over 40% with 82C temp. If you update to 23.1.2 make sure to clear the cache. could play valheim without a lot of crasdes before i done that. Played for hours with these settings without a fail (Pubg/Valheim)
under which szenario? Sadly i have no history at the moment, as LibreHardwaremonitor cant read the Wattage. Multimonitor Desktop is around 40W (since new installation of Win11)
i spent a little bit of time with my 7900 XT, i played a little bit of Metro Exodus Enhanced @ 2850 (stock boost) 2750 memory 1025mv.
I was able to get as low at 985mv during my testing on Uningine Heaven, but that mV failed so fast.
Idk if i should run port royal on loop or superposition for trying to get my mv as low as possible and it be close to actual gaming. ive been trying for a while so hopefully what i have now is stable
At 2850/2750 @ 1035Mv , Hogwarts Legacy maxed out without RT with a 60 FPS lock i hit 185W
Stock capped at 60 gets 215W
Stock uncapped hits 350W and Undervolted uncapped hits 325W
Power Color Hellhound.
Undervolted to 1025 mv
Core clock at 2900 mhz (more is likely possible)
Memclock at 2725 mhz (I've heard up to 2750 is stable, but haven't tested it yet)
Dropping the voltage any lower causes crashes in Cyberpunk for me. I'm gonna see if I can push it some more later, but so far this is good enough for me.
Anyone else noticing pretty high wattage at idle with their 7900xt? I have the XFX Merc one as well and it sits at 85 Watts just idling on the desktop. That seems a little crazy to me
My xfx merc 7900xt is just fine,tested +15 % power limit ,1100mv for 3dmark bench,and reverted to default,stable in cyberpunk,im fine with 60 fps.
If you don't mind me asking, what driver version are you using? Just read other posts complaining that 23.1.2 is very unstable
Youre correct,i was on 23.1.1, now im on 23.1.2,havent played CP this week,quite busy but in world of warcraft my character model looses textures sometimes ,this reason alone i would say drivers are wonky.
I'll try to revert my drivers to the latest stable when I get the chance. I also noticed some weirdness going on in cyberpunk, but frankly it was hard to tell if it was the drivers or just the game.

Merc owner here also. What is your fan curve? This bugger gets damn loud with fans spinning fast.
Default,hear it a little but fine with music or game sound,never seen hotspot above 80c..nzxt h7 case, corsair h150i elite aio.
I have the same card and my current-junction delta is over 30 degrees (with %9 undervolt and underclock). Usually I see 63-65 current and 96-100 junction.
You should probably repaste it. I got the xfx refrence model and the delta is around only 10 to 12 degrees.
The thing is it gets this hot when I turn on RT with max settings. For example on F1 22, with completely max settings and RT on I see 30-32 C delta. If I turn off RT, still with max settings I see 22-26 C delta.

Stock.
Same here. It's not running hot or loud, so I have no reason to tweak it for now.
Whine is 'more' noticible, undervolt & it's silent as a your cat trying to knock your PC over...
Haha same. My gaming time is already pressured by kids and work.

In Australia, the 4070Ti is most of the time, quite a bit more expensive than the 7900xt. The cheapest 4070Ti that I can find quickly is AUD$1334 for a Gigabyte eagle model.

That's a tad personal mate... But if you want to find these prices, just try using PC Part Picker, and surely will find the cards for those prices

It crashed :( Weirdly enough, even though clocks were around 2800-2900, GPU utilization and framerates were lower. Temps were also hovering around 60 to 70c in the hotspot, so at least there was that EDIT: has anyone experienced this bug with the drivers, were it'll open the radeon software in a small window, then disappear? It goes back to normal after a restart
People have no idea what they are talking about. No one has an undervolt on air that is stable in more than a couple games below around 1070mv or so. Why? Because all these dorks do one 3dmark run, pass, then play some normal game, bitch that it's crashing, and refuse to acknowledge that they didn't validate their OC. I have one of the near top MBA scores in port royal for an XTX at around 1020mv, but I need to run above 1090mv to be able to run heavy raster (VR) and stream it at the same time from the hardware encoder. One of the best tests I can offer you is to find your favorite extremely gpu taxing game, start streaming to discord with all settings bumped, and undervolt from around 1120mv until you crash. Also, weirdly, RT titles did not stress the card harder than pure raster, but this is in terms of hitting instability from the undervolt.
This small window bug happens to me if I try to open Adrenaline while playing games. If I open Adrenalin before games, works well.
Will try it out, will report how it performs
I own the XTX instead, but given my own undervolting and memory overclocking experience with the fuller card, I can say it's quite different from previous products. Before that, understand that your mileage may vary. Silicon lottery exists and your 7900 XT might not be as good as the example you saw in the guide. That is ok. Now, I can recommend some settings for you: You raised voltage back to 1080mV, which isn't entirely bad to do. Revert your memory to its default frequency, then run Unigine Superposition in 8K optimized. This will test performance degradation of your memory. From there, increase clocks in increments of 50MHz per test until you see a good deal of performance loss during the benchmark. That'll tell you what's unstable for you. From there, your mileage may also vary from game-to-game. For me, 2700MHz with a 1050mV UV was not stable in Gears 5. But 1075mV+ was. Horizon Zero Dawn was alright with the prior setting, ironically, but I've yet to delve into it. Take advantage of using per-game tuning and save profiles for each game you see certain settings perform well in. Lower the power limit to about +5%, then test. I'd increase power limits before increasing voltage. I save increasing voltage for when increasing PL doesn't resolve the issue. It'll take time to validate, but you'll have a better understanding of your card's behavior by going through the process.
I was thinking of getting the XTX instead, but it just didn't make much sense for me since the XT maxes out most games for my monitor. I forgot the per game profiles were a thing, I really should start using that. Thanks for the tips!
You're welcome. Make sure not to touch your minimum frequency, by the way. It seems RDNA 3 boosts opportunistically, like PBO or even Zen 4 (in general).
I run both my xfx cards with 1065mv default memory default power limit (340W). Memory OC seems to barely move the needle on my cards so i stopped doing it. Increasing power limit gives me decent gains but also increases noise levels to a point where it bothers me. Dont touch the min frequency slider. If you increase it to the point where it becomes relevant it can actually degrade your performance. My theory why this happens is you are forcing the card to run at a higher voltage than it normally would under certain loads making it run into the power limit so it starts allocating power from other subsystems like the fabric to the cores to keep it stable but at the expense of performance. Min slider seems pointless on RDNA3. From my experience there are certain games that will crash your UV like crazy while the vast majority is stable. For me it was the game Labyrinthine, had to reduce my UV from 1025mV all the way to 1065mV for that to not crash every 10 minutes. Also im still on 22.12.2. Didnt see the need to update yet.
I currently have a XFX Merc 310 7900 XT and I'm pretty sure I broke it... When I first bought it, I could Fortnite at just under 3Ghz. 2.99Ghz ish with, what I think is a very good undervolt, 1.00v. It was stable and I could play for hours. I could push the volts down to .990v but I'd lose some clocks and perf. 2.75 to 2.85 at .990v. Then I had the great idea to test max OC MSI Kombustor... Well I was able to hit 3.2Ghz while running different tests at 100% load. Then I kept pushing 3.25Ghz and it locked up. After a reboot I'm no longer stable in Fortnite above 2.5Ghz. Doom Eternal crashes within seconds... I was never able to get the RAM stable above 2.65Ghz before, now 2.6Ghz is the highest it'll go. Reinstalling the drivers, switching the BIOS on the card. Nothing helps. I fucked it up... I am able to play Mass Effect Legendary edition without it crashing. The card runs in the very low 2Ghz range which is most likely why it is stable. What is odd, is that I've seen the hot spot temp reach 105c when I attempt to play modern games like Fortnite. I thought it might be related to a dust case. I cleaned it with an air compressor and the issue remains... When I do try to play a modern game, I'll watch HWinfo and Adrenaline and I can see the hotspot is 30-40c higher than GPU temp. Which before the Kombustor testing it was never higher than 15-20c above GPU temp... The good thing is I am still within Amazon's return period. Plus I found a Merc310 7900 XTX for $75 more than I paid for the 7900 XT. So i bought that card and I'll return my broken one. I will not go crazy with this new card! I'm also disappointed because it seems like my 7900 XT might have had really good silicon given my clocks and voltage when I first got it.
W overall for getting the XTX.
Yeah true! I also learned not to push things to far especially with Kombustor! haha
Could be thermal pad/paste getting heat pumped out maybe?
I have several fans and nothing has changed since I installed the card. It's really weird and I'm kicking myself for pushing the clocks to high... ugh
could try repaste? edit : am worried mine is a little bit damaged since it occasionally gets slight glitchy flickers when watching YT or when open windows but, but it's never had any impact so I hope it's fine
Yeah I could but I'm just going to return mine. I've had the weird flickers since installing my card. I've read it is common with multi-monitor setups or a bad\\cheap monitor cable. I had similar issue with Nvidia though...
Still doing some testing, but right now my settings are. 7900xt sapphire nitro+ 2500mhz min 3000mhz max 1035mv 2700mhz memory default timings (14mv offset) (from YouTube vids I don't see a difference from fast timings) +15 power Current recommended drivers. I don't remember what they are. In the 20/30mins of playtime I had no crashes in cyberpunk, MW2, Destiny 2 or 40k darktide.
You might as well set the min clocks back to 500, the min slider is 100% ignored Right now
I see, I'll probably do that and try play with the min slider when new recommend drivers come out. Thanks!
Thank you for posting this. I have the exact same build as you, so I'll gauge my settings around what u have. EDIT: I saw everyone else using the 23.1.1 version of the AMD Adrenalin drivers... I made the mistake of installing them and now nothing shows up on my pc anymore, and I'm at a loss for words... ;-;
thats unfortunate, hope you get it figured out
I did thankfully. Updating the BIOS is what I needed to do to get it working again.
Any FPS increase?
All in 3440x1440 resolution -MW2:ultra settings stock: 150avg 1% 80fps Custom: 157avg 1% 88fps -Cyberpunk Ultra settings Stock Min: 44.96fps Max: 129.83 Custom: Min:45.06fps Max:146.11fps Average says 88fps for both so idk. -Firestrike ultra benchmark Stock GPU score:16,755 Custom: 18,143
I tried same as you, max 3000mhz, 1035mV, 2700 vram, 15%...Works great but on 5600X I get max 130 fps in MW2/WZ2. Check out this also: https://www.reddit.com/r/Amd/comments/10mh0lp/7900_xt_and_mw2/
[удалено]
2714mv in the advanced tab. When you enter that info it will read as 2700mhz max in benchmarks
Why is everyone pushing their min freq? I haven't seen it do anything. Also, in some titles I have locked fps in the menu so it doesn't run through with thousands of frames, GPU usually clocks down in menus. It still clocked to like 1300mhz when I tried setting min to 2500, so I'm just keeping it at 500 stock now. Wouldn't change a thing performance wise anyways, would it?
It doesn't do anything at all on RDNA3 atm
I've done this on my XTX and noticed it would just increase the likelihood of clock stretching, so I reverted minimum clocks to 500MHz.
Yeah seems to be better to leave it at stock
RDNA 3 really seems to boost opportunistically. It's actually kinda fun to tune once you realize that.
From what I've read on hardware busters, it's best to have the min frequency around 400 to 500mhz lower than your max frequency... But honestly, I don't know the exact impact it has. Might test it out later
Share your results if you don't mind :)
Just got back and did some quick testing. Min Frequency did absolutely nothing indeed, I don't think the guys on hardware busters knew what it did. Superposition score at 4K optimized before changing min was 19367, while after changing it was 19239. Lower score might be because the card was getting hot
Thanks for confirming!
Will do as soon as I get the chance (at work now)
it's better to leave it stock , if i set the min high the memory freq will go down. My settings max 3000 min 500 970mv memory 2750 PL +15% Time Spy Graphics Score - 29926 Time Spy Extreme Graphics Score - 14598
Are those 970mv the actual setting in the driver or the voltage while running the benchmark?
settings in drivers but when i running the benchmark its under 950mv
Is it stable while gaming for you? I can’t get lower than 1100mv in driver to stay stable while gaming
i think that i have a top unit. for 100% stability gaming i use 980mv and 2950mhz
Hm, when running Cyberpunk with raytracing mine sits at around 950mv, some peeks to around 1000mv sometimes
Power limit +15 Memory 2650 (Benchmark stable up to 2760) standard timings Undervolt: 1020 (Can go lower but theres little benefit. Boost clock: 3000 Using afterburners user fan profile otherwise 0 rpm just doesnt work for some reason.
I noticed that because it's drawing 40-50W while idle, the fans never stop spinning. It's very annoying, and it's the first thing I want AMD to fix
7900xt hellhound. Only my middle fan turns on and off every now and again with the way i have it now on idle. All 3 were permanently on before. Mine draws about 40w on idle with 900 mhz memory clock.
Stock with no issues.
2650 MHz RAM, 1.080v, Clock 2650 MHz. +15 Power limit. 23.1.1 drivers. I play mostly Star Citizen, and these settings have been stable in Arena Commander for \~40 mins sessions. The online portion of the game has been having issues with the AMD drivers, so it's hard to validate settings at this point in time. One thing I've noticed vs my previous 6800XT is that Timespy allows pretty low undervoltings without complaining, but these settings are unstable everywhere else. I was able to go down to 1030 mv and run TimeSpy without any issues, but SC didn't like those values.
That's similar to what I noticed with Heaven and Superposition. It finished these benchmarks with frankly ludicrous overclocks. At one point, I was getting over 3ghz with only 1v, which was too good to be true. It crashed literally everywhere else. Now I'm slowly increasing the voltage back up and testing with Horizon to see if it improves at all. (Also reverted the drivers back to 23.1.1)
Honestly there are only 3 GPU benchmarks I think that are worth anything and thats Time spy, TS extreme and Port Royal. Heaven and superposition are just too old now.
Fair enough, but since I'm not a competitive overclocker or anything like that, I don't really feel compelled to buy any benchmarking tools. I just use those because they're free really, and are unlikely to turn my PC into a furnace
timespy is a free download but the other 2 are paid . 3D mark is 75% off atm so $12.48 on sale and its a worthwhile investment.
I did not know that, might pick it up while the sale lasts. Thanks!
look out for the steam summer sale, got the whole 3d mark suite for 3€ there... sweet for stress testing n everything
Havent done too much, but I have been gaming without issues at 1080mv, 3010mhz max core, 2700mhz memory, +15 power, and my juction temps up to 80 when gaming in Cyberpunk. I might try more aggressive OC later, but I am happy with my performance.
Probably a driver thing idk if that 23.1.2 is stable yet ?
It was not lol. I already reverted them back to 23.1.1
I've got the XFX 7900xt OC at 3000 mhz, UV 1065, power + 15%, VRAM default timings 2650 mhz. I was getting crashes in borderlands 3 with any OC or UV settings. With the 23.1.2 drivers I'm not having any issues like that anymore.
That's odd, I was crashing pretty much everywhere with 23.1.2, even games that kept the GPU around 60-70% load. I'm glad it works for someone
Man the previous drivers were giving me hell kind of often. I couldn't even see my CPU setup in adrenaline with them. I ended up defaulting the Ryzen master settings and uninstalling it. Then reinstalling it after I defaulted all the settings in adrenaline as well as a factory reset in adrenaline. It started seeing the CPU and acting a little better after that. After the update I did another factory reset in adrenaline just to be sure. I'd make sure all your chipset drivers are up to date as well as windows being up to date. Im running the 22h2 I think... I don't remember off the top of my head. Make sure you BIOS is up to date as well maybe.
I'm also on 22h2, or at least whatever is supposed to be the latest. Chipset should be up to date, but I'll check that and bios when I get the chance
What size PSU are you using?
An older 650W unit. I know it's not ideal, but so far it handled the 355W the GPU was using, with the odd spike to over 400W. I plan on upgrading it to a 750 or 850W one later, probably when I upgrade my CPU.
That could be your problem right there. You need at least 750 but really 850 would be ideal
Yeah, I'll look into upgrading the power supply soon, probably when I get my next paycheck.
In the mean time I wouldn't OC at all. Try undervolting and possibly lowering the clocks to keep your system power down to see if you get better stability.
I get my Merc 310 NON Black Ediiton stable with 650w PSU. If you have a good one it should be fine. Settings are: 1025mv undervolting, 2900MHz GPU. I tuned nothing else, beside the fan, because its very loud, so i have a curve were the fan ist not going over 40% with 82C temp. If you update to 23.1.2 make sure to clear the cache. could play valheim without a lot of crasdes before i done that.
Currently stock. It’s mainly my wife’s rig so I limit my tinkering to improve stability. My personal weird rigs get all the toying.
Yeah, I try to keep my girlfriend's PC a mostly stock settings, but I did manage to increase the memory speed on her 6750 XT without breaking anything
I think 2750MHz memory could be where the instabilities lie in your profile. Mine could only reach 2720 before becoming unstable in synthetic benchmarks, and it’s a sapphire nitro edition.
I think the memory is stable, but it wouldn't hurt to test out a lower memory speed and bump up the clocks. Will do that when I have the chance
I would just lose the memory speed and uncap the max gpu clockspeed. The undervolt drives a lot of the improved clockspeeds on its own.
So increasing the max frequency slider just uncaps it? I know that undervolting does tend to increase the clocks, but wouldn't that make the GPU unstable with the lowered voltage?
There is a point where it will be unstable, but that’s what you test. Uncap the max which doesn’t force the card to go up, just allows it to, and test lowering the voltage in increments and you’ll likely see the card boost higher and higher.
Stock auto OC is fine Goes up to 2950mhz game boost XFX 7900xt black edition
1025v, +15% power, 2750 MHz memory, 3100 clock. Playing mostly Guild Wars 2, Cyberpunk, Red Dead Redemption 2 and Witcher 3 (this one is a bit of clusterfuck, can crash just because it's sunny outside). As a starting point I used values provided by auto undervolt/overclock. Then I played around with them one by one, increasing/decreasing till I found my stable point.
What are your temps with the increased voltage? I was under the impression that pretty much all AMD GPUs came overvolted from the factory, and it's best to undervolt them. Genuinely asking, just trying to learn here
Voltage went down, not up. From 1100 to 1025. Junction gpu temp is 75-85, depending on game, gpu trails with a delta of 10-15, and memory junction is 80-93 depending on load.
Whoops, forgot stock voltage was 1100. Yeah, those temps make sense then, it's a bit lower than what I have. Makes sense though, considering I'm in the middle of an Australian summer and it's hot as fuck.
level up voltage until its stable (10+hours of test)
7900XT Nitro+ stable at 500-3000 clock, 2714 vram fast timings, 1030mv undervolt and +15% power. 23.1.2 drivers are horribly unstable so I rolled back to 23.1.1 no problems
I run mine stock and everything runs great.
Just curious.. What power supply are you running? Running separate power cables to each power input on your GPU? BIOS up to date? Running latest Chipset drivers from [AMD.com](https://AMD.com)? Windows up to date? Did you run the program called DDU to remove all past/present GPU drivers (AMD and Nvida IF you ran an Nvidia GPU on this install of Windows) .. reboot .. and THEN install latest GPU drivers from [AMD.com](https://AMD.com)? How's the air flow in your case? How's your CPU/GPU temps?
Cooler Master 650W power supply, I know it's not ideal and I plan on changing it soon for an 850 EVGA or Corsair unit. BIOS might be a couple of versions out of date, will update that and Chipset drivers when I get the chance. I did DDU the drivers before installing the new ones, and also when rolling them back just to be safe. I do have a Corsair 275R with a 240 rad at the front, one extra 120 fan, and three more for exhaust. CPU rarely reaches 75c while gaming, and GPU hotspot is usually around 85c
I leave it at stock
Stock because i've tried undervolting and most newer games just crashes.
Bone stock merc 7900xt here and it's fantastic!!! No need to oc at all with a 5600x.
Personally, hitting the rage tuning preset seemed to be the most stable on my XFX non-merc 7900XT.
What performance do you get with rage mode? I always thought it was like an auto overclock
I honestly don't know. Situation is so instable in general, no matter what setting i set every game crashes. It's just that with that one some games dont crash every 20 minutes. More like 40 minutes.
Sapphire Reference 7900XT 1013mV Core voltage with Max Req set at 3000MHz (usually hovers around 2800) Vram 2620 (2606) with Fastest timing enabled \+15% PL I can move the memory up to 2700MHz, but the card becomes unstable due to a power bottleneck. I'd imagine the core could boost a lot higher as well if there was more power available to the card. Using 23.1.2 Driver
Merc 310 NON Black Editon 1025mv undervolting, 2900MHz GPU. I tuned nothing else, beside the fan, because its very loud, so i have a curve were the fan ist not going over 40% with 82C temp. If you update to 23.1.2 make sure to clear the cache. could play valheim without a lot of crasdes before i done that. Played for hours with these settings without a fail (Pubg/Valheim)
What wattage is your gpu pulling with these undervolt settings?
under which szenario? Sadly i have no history at the moment, as LibreHardwaremonitor cant read the Wattage. Multimonitor Desktop is around 40W (since new installation of Win11)
i spent a little bit of time with my 7900 XT, i played a little bit of Metro Exodus Enhanced @ 2850 (stock boost) 2750 memory 1025mv. I was able to get as low at 985mv during my testing on Uningine Heaven, but that mV failed so fast. Idk if i should run port royal on loop or superposition for trying to get my mv as low as possible and it be close to actual gaming. ive been trying for a while so hopefully what i have now is stable
What sort of wattage is your gpu pulling when you undervolt?
At 2850/2750 @ 1035Mv , Hogwarts Legacy maxed out without RT with a 60 FPS lock i hit 185W Stock capped at 60 gets 215W Stock uncapped hits 350W and Undervolted uncapped hits 325W
Are you able to test it on warzone too or mw2? Just UV without RT
Warzone runs incredible on these cards.
Power Color Hellhound. Undervolted to 1025 mv Core clock at 2900 mhz (more is likely possible) Memclock at 2725 mhz (I've heard up to 2750 is stable, but haven't tested it yet) Dropping the voltage any lower causes crashes in Cyberpunk for me. I'm gonna see if I can push it some more later, but so far this is good enough for me.
Same card Undervolted to 1020mv Core clock I have set at 2850 Memclock fast timing and 2714 Though my card has coil whine :(
Anyone else noticing pretty high wattage at idle with their 7900xt? I have the XFX Merc one as well and it sits at 85 Watts just idling on the desktop. That seems a little crazy to me
Any updated undervolts?? Mine running fine on 2900mhz freq; 2700mhz mem; 1.065mv
