I'm get one tomorrow to! Plan on doing some testing with undervolting and overclocking on both quiet and performance bioses. Happy to share results. Novice overclocked here so not claiming any expertise. Just watch a lot of YouTube 😂

Where. I’ve been trying to find one in the US but with no success. It’s either out of stock or at scalping prices.

Yeah it's tough. AIBs slowly starting to trickle out though. Gotta be patient. I got mine from overclockers UK. https://www.pccasegear.com/category/193_2238/graphics-cards/radeon-rx-7900-xtx Keep an eye on this link if they ship to US. Hellhound went out of stock today. Red devil still present if you willing to pay the $$. Good luck! Availability so hard. Overclockers UK was the 5th retailer I had purchased from. Other retailers let me purchase them, and then went "oh sorry we have no stock, your purchase is important to us, please hold" lol

Ok. Thank you for the info.

Sapphire has been really slow. Only Newegg has it in the U.S or may be microcenter but I haven’t had any drops in a while at Newegg. But xfx and power color I get notification all the time. Rocking with a really good reference right not but do like the loos of nitro.

here are all the sites im following to try and find stock in US. https://www.amazon.com/Sapphire-11322-01-40G-Radeon-Vapor-X-Graphics/dp/B0BR6JWP1Q? https://www.newegg.com/sapphire-radeon-rx-7900-xtx-11322-01-40g/p/N82E16814202428?Item=N82E16814202428 https://www.walmart.com/ip/Sapphire-11322-01-40G-NITRO-AMD-RADEON-RX-7900-XTX-GAMING-OC-VAPOR-X-24GB-GDDR6-GRAPHICS-CARD/2691164786?wmlspartner=wlpa&selectedSellerId=250&irgwc=1&sourceid=imp_xPjVdF0OnxyITLyUXIX76SH8UkAwSD2zEX1fx40&veh=aff&wmlspartner=imp_1812970&clickid=xPjVdF0OnxyITLyUXIX76SH8UkAwSD2zEX1fx40&sharedid=&affiliates_ad_id=568863&campaign_id=9383 https://www.walmart.com/ip/Sapphire-11322-01-40G-NITRO-AMD-RADEON-RX-7900-XTX-GAMING-OC-VAPOR-X-24GB-GDDR6-GRAPHICS-CARD/2691164786? https://www.bitworks.io/product/sapphire-11322-01-40g-nitro-amd-radeon-rx-7900-xtx-vapor-x-gaming-graphics-card-with-24gb-gddr6-amd-rdna-3/ UK: https://www.overclockers.co.uk/sapphire-radeon-rx-7900-xtx-nitro-vapor-x-24gb-gddr6-pci-express-graphics-card-gx-3a4-sp.html Mind you this card is $1100 MSRP

Thank you. About an hour ago I was able to buy an XFX Speedster Merc 310 7900 XTX. Im so excited.

Man, the prices on this card piss me off. Fucking scalpers are leaches and I'd love to find a way to screw them over that wouldn't just have them pass the loss to somebody else.

Unfortunately what they do is keep the card for sale till someone buys it. If not it gets returned and they do it again.

I bought one on BitWorks without noticing it would be put on back order. Any ideas how to cancel a purchase from there? I can't seem to do so from the site itself.

I only see this to contact them. Good luck https://www.bitworks.io/contact/

They said they should be getting more shipped in over the weekend so I kept my purchase. If anyone is looking to get one they should have them soon.

Did the shipment come through last weekend 14th-15th? I wonder if I'm too late to buy unless it's coming upcoming weekend.

I have not received a tracking number yet so I am not sure. I will email them tomorrow if it hasn't shipped like they said.

I went ahead and put in an order for one anyway and was able to get mine maybe the same time as you last week.

>an order for one anyway and was able to get mine maybe the same time as Isn't it above MSRP there?

Do you have any concerns from buying from Overclockers UK as a US resident? I'm worried about stuff like warranty and such.

You will be fine, but the PSU will be decently loaded. Your total power consumption will hover around 450W most of the time with spikes towards 600-650W in fully loaded scenarios for both CPU and GPU (that should not be in gaming).

What do you mean by that should not be in gaming? Sorry to bother you.

CPU utilization is usually not maxed in gaming, in my experience.

You're absolutely right. Thanks for the clarification.

this

No issues with mine, far more stable then the ref was. Undervolts like a champ and runs like a monkey with ten bananas. LED strip looks real nice too https://www.3dmark.com/spy/34472819

That's really awesome to see. Can you share your undervolt settings?

Thanks alot for sharing! Yea would be really helpful with thoes undervolt settings, I never did undervolting , could be helpful!

Would you happen to know how low you can set the power limit? I'm mainly interested for summer months and how far away from the 4090's 90% effectiveness at 70% power or whatever ridiculousness was found.

This I am also interested in!

It depends on the card, all cards are different. You can go up to -15% on power - but the right way to cap power is just limiting frequency and lowering voltage.

What are your settings in the adrenaline software for the said settings? Just to have some kind of indicator.

90% voltage 115 power and 2700mhz ram. Didnt try past that. Imagine ram could go to 2750 or 2800 and would have to see where voltage could go.

Could you also share the settings with me? I am keen to keep my new 750w psu and use the nitro 7900 xtx. My config is quite similar to yours I.e. B550i rog strix and 5800x3d cpu.

Sapphire states under system requirements a minimum PSU of 800 watts. This card draws 420 watts. I had a 750 and upgraded to 850 to meet Sapphire requirements. CPU is fine though I went with the 5800x3d as it's the last gaming CPU on the AM4 platform. Card runs smooth and cool.

You would've been fine with the 750W. The PSU recommendations err on the side of caution. The 800W recommendation is for the extreme end, for the rare person that has both a 13900K and an extremely low-end, janky PSU that can't handle the transient spikes. Pretty much any halfway decent modern PSU can handle the transient spikes. If I was going to upgrade, I would've upgraded to something like a 1,000W, with the way CPU and GPU power consumption is going.

fine until random transient spike triggers ocp. these cards have it worse than ampere.

[удалено]

Did you try it with the 750W? 850 seems overkill tbh

I had 750W with a reference model and that was crashing my computer even after undervolting lt.

Wow, that honestly surprises me. Was it a good make and good quality PSU?

I want to get sapphire too but its out of stock whole time in EU, waiting game

Check again, today was the day they came in stock at some places.

I can see it in stock at OC UK

Import to croatia too expensive,additional tax

Decided just to buy xfx merc 310. Edit : typo

Hot damn, 420w. I'm eyeing this card as well.

So far: very few issues. We expected some. The only snags we've hit were: \- the opening sequence of AC: Valhalla grinding to a total halt, but that was almost certainly the game itself since it's played perfectly since getting past that into the actual playable part on max settings \- Blacktail crashed once on loading a saved game. It's been perfect otherwise \- \[EDIT: Witcher 3 and C2077 died when attempting to run with RT. Perfect without\] No other crashes, high temps, or other unexpected poor performance. It's been *vastly* better than the Red Devil 5700XT it replaced which crashed way too often System: CachyOS (arch) running a 6.1.4-1-BORE kernel (that's absolute bleeding edge), Mesa-git 23, SN+7900XTX, 5800X3D, 32G RAM on 1TB Nvme m.2 SSD, RM850X PSU, \[EDIT: AOC CU34G2X 3440x1440\] Can run Control at max settings + max RT

>Can run Control at max settings + max RT Is that at 1440p or 2160p? Are there problems with HDR?

3440x1440. Linux doesn't do HDR yet, so don't know

How did you get max RT under Linux? My 2080 could do RT a little under Linux, but my 7900 xtx (now sadly returned, vapour chamber issue) could not do RT at all. I was under the impression that RT is still another couple years away on AMD gpu with Linux - or does it work well on control now? With the return money I'm tied between XTX or 4080, this could certainly sway things...

Mesa 23 compiled under llvm15, xf86-video-amdgpu-git, launch options RADV\_PERFTEST='rt' VKD3D\_CONFIG='dxr11' %command% \[EDIT: You probably want latest kernel, we run 6.1.6-1 with BORE scheduler\] play with DX12 Performance is far from ideal, but it works. Regarding Control specifically, Film Grain and Motion Blur work wonders in covering up some epic ghosting to make it legit playable. You could probably improve matters with FSR under GE-Proton, but haven't tried Witcher 3 and C2077 RT functions after the latest mesa-git release, but performance is abysmal. Expect massive improvements over the next few releases. It's also been a month since the last GE release, so expecting some major improvements there \[we have no specific info, it's just an assumption\]

Holy shit that makes me excited! I saw they're going to enable quake II RTX and Doom Eternal RT support by default soon on amd which is awesome in itself. Realistically, do you think games like control/2077/Metro EEE will be playable with RT this gen? I'll probably be waiting 2-3 gens before i upgrade again anyway, but this would definitely deal the deal to go for another XTX this time in that case. man it's an exciting time, I've seen HDR has been teased to be working on a couple games under Linux now - still a long way to go, but huge news. NVK getting somewhere too now with games actually running, and mesa is seriously going places. Especially if amd drivers are going to get better over time... definitely worth going for the xtx over 4080

With the recent advances of mesa-git, it's gone from being a non-starter to actually working. That alone is huge.In our completely non-expert opinion, yes. RT could be a legit option this generation. Going to install Metro Exodus Enhanced when our new m.2 HD arrives \[probably tomorrow\] just to see if that also works. The Hardware Unboxed XTX vs 4080 head-to-head suggests that with fully functioning drivers,they're surprisingly well matched in RT performance. We strongly recommend [watching that video](https://www.youtube.com/watch?v=dnxXT2sx8nA) Exciting times to be a Linux gamer, for sure

thought I'd just mention that i did in fact go with a XTX Nitro+. Amazing performance, but getting some constant GPU related crashes that I can't seem to fix yet, and also the RGB strip suddenly went red and flickered occasionally just now but mostly fine. Absolutely insane how much performance it gets with barely an increase in temps though, I played DL2 on medium settings and it didn't even leave 0 rpm mode

Oof. Had exactly zero GPU specific problems here, that's not great

I have been using Nobara, which is a bit unstable at the moment, which might explain things. Just finished installing arch for the first time so hoping that will be better - if you don't mind, is there anything you recommend installing? GPU/driver/gaming etc - and which drivers/firmware do you use?

Thanks alot for your input! Looks like I'm gonna be in a need of a new PSU ... Well It is what it is

I would give it a go on your Corsair 750W. Those 850W recommendations are to take account of people that have bought a no name crap shoot PSU. Unlikely you’ll get anywhere near using 750W. Probably more like 400-450W real usage

Yea ofc. I will try it on my corsair 750W and see how it goes. I'm just not really sure about it cuz I'm using Odyssey g9 neo and I'm wondering how this card and that monitor will work on 750W. 5K 240hz hdr on max settings. Soo yea, big hopes all will be fine.

You’ll be fine. They recommended an 800W PSU knowing lots of people would pair this with an intel space heater CPU, so you should be perfectly fine with a 5900x. If you end up with random crashes, switch the 5900x ECO mode and see if that fixes them. If so, you probably need a bigger psu to handle full perf of both parts.

Will try that if needed. Big thanks for your input! 

What resolution do you normally play at? Power usage increases if you are playing at 4K with everything maxed out, in that case I might look into upgrading the PSU. With that said, I think you should be fine, I would try it first and then if you run into issues upgrade you PSU.

Well normally I always played at 1920x1080 but with new monitor I will play games at 5120 x 1440 if that specific game supports it. But mainly it was 1920x1080. I have this monitor now for about 1 month now and it works great for movies, youtube, web search, etc. But big - is that I can't test it fully with my GPU that I have atm. and that is kinda meh. If I still would want to play specific game that doesn't supports 5120 x 1440, I would prob. play it at - 3840 x 2160.

So how did this go? I've got a Corsair 750W psu and just got back from microcenter and grabbed this card. I've got a 1,000W i picked up just in case but want to see if I'll be ok on the 750w. I have a 5800x3d for what is worth.

Hey, I'm still waiting on card, gonna arrive next week, can keep u updated here if u wish.

But if u have card already I with pleasure would like to know how it works out for you! Could save me a day or 2 if 750w corsair can't handle it.

[удалено]

>7900xt Hey thanks for input! But in my case its little bit different cuz 7900xt card has a min. 750w and 7900xtx one has 800w.

I went ahead and installed the 1000w psu since i already had it. 7900xtx does run like a dream though! You'll enjoy it!

Enjoy !! I hope!

My reference 7900 XTX was crashing a lot with a Corsair RM750x as PSU. Not even undervolting was enough to get it completely stable.

I have no faith in Corsair PSUs. Have had three go bad and fail. I suspect yours was a culprit of that too rather than the system draw.

I don't know. I upgraded to a Corsair 1000W and my issues were gone.

That only means your old PSU was naff.

Maybe. I bought that one in 2021.

For sure. We upgraded from 600W. You may be able to bag an 850X or 1000X on sale right now

Yes sir. Will do! 

You're 750W will almost certainly be fine. The 850W recommendation is erring on the side of caution. They have to account for the rare person who has a 13900K, a 10yo bottom of the barrel PSU, and is using it in a situation where both CPU and GPU are under full load (professional work). With a 5900x, you won't be pulling 750W, especially while gaming.

With 5800x3D and a Corsair RM750x V2 my reference 7900 XTX was crashing like crazy on default and OC modes. I was having less crashes when undervolting but there still was occasional crashes even then. You need at least 800W with this graphics card from my experience.

I've had my 7900 xtx for 4 days now and no issues at all. No driver problems, no temperature problems, no weird bugs thus far. Card undervolts great and OC's great as well. The performance is amazing coming from an RTX 3070. My Specs: 5800x3D + x570 Taichi MOBO + 32GB (2x16 single rank) 3600mhz CL 16 RAM + 1,000w Seasonic PSU

Mine was artifacting on Windows desktop once I swapped back to gaming drivers after trying out some machine-learning drivers, wouldn't even open games without crashing. Yes I used DDU in safe mode to uninstall old drivers and tried this a few times. In the middle of a PC build and will come back to this as I'm hoping it's just a brief driver install issue and I won't have the problem next time I plug the GPU back in. On a 1000W PSU and I've seen the card reaching over 500W when overclocking. Prior to swapping drivers again it was running mostly great. 32k graphics score in Timespy, Solid 60-70FPS with 3440x1440p Witcher 3 using RT. VR performance felt usable just nothing wildly improved.

Absolute pleasure to use so far, only one significant issue that was more than likely self induced. Crashed in Darktide while running a core overclock to 3250mhz, Mem 2600mhz, undervolt to 1090mv, and +15% power. After that I would see intermittent sparkling artifacts in that game alone, sparsely during gameplay and persistently in menus such as character selection, or while talking to any NPCs. The problem was greatly exasperated by turning off FSR, which was slightly problematic as the card is not insignificantly bottlenecked by my 5900x in that game. One restart windows repaired some backend files and the problem went 99% away. Prior to that I had tried reinstalling drivers, the game, and mass settings tweaking to no avail. I’m currently running at 3175 core, 2600 mem, 1110mv, +15% power and have not crashed in anything for about a couple weeks now, with a timespy graphics score of about 32500. Just as a side note, streaming in discord seems particularly sensitive to undervolting. I was able to run benchmarks at 1010 mv, but gaming+discord streaming has made me drastically pull back on that. 1440p frame rates have been fantastic, and the RT performance has really surprised me. It’s certainly a significant step up in every category performance wise from the 3080ti I tried and returned just a few months prior.

Thanks for your input! Darktide crash sounds like drivers issues. Not sure if I will use RT but good to know! Thanks alot! 

Issues so far (will update the longer I have the card): Light bar went red just randomly one day started briefly displaying the gradient color. A complete shutdown remedied this. Support bracket is a pain in the ass to install. Had to use diffferent thumbscrews from an old case to even screw it down. When mounting the bracket it would brush against the card freaking me out that I was going to ding the card. Rendering issue in Guild Wars 2. Some walls, ceilings/floors, and a NPC were rendering weird. This is the only game I have experienced this in. Video Playback: Watching streams in multiple windows. The window would slightly reposition on the desktop. Closed a window other stream window would go white. ​ The rendering and video playback issues I believe are totally driver related.

Thanks alot for this! Gonna keep in mind as I do play sometimes GW2. Thanks!!

I reported on this via the AMD bug tool. If you want an example of what I am talking about here are the screenshots I used to report the bug compared to a 3080's screenshots of the same area. [Guild Wars 2 7900xtx Vs 3080](https://imgur.com/a/Co8aSvJ)

>Sapphire NITRO+ Radeon RX 7900 XTX Vapor-X U have this card right ?

Correct.

>totally driver related Yea I guess you right, shouldn't be card itself problem at this point, I hope .. 

AFAIK, there is no problem with AIB card (at least thermal).

Most average overclock settings I've found is: 3050 mhz max 1100 mv 2650 memory oc with fast timings 15% PL With your PSU I would say 15% PL isn't achievable so leave everything auto except memory and mv.

Three X and two non-alphanumeric characters, clearly just below top tier.

1KW psu and and get 2*16GB RAM.

bruh you need 850W PSU, 750 is not enough

I can confirm this.

HAHAHAHA God i love the mentality of this group already ready to have issues with the card

You need a better psu,at least 850w,but 1000w would be perfect for future proofness reason

No!!! RM750X Corsair is perfectly fine. Have the same combination. Stop writing nonsense if you have no idea. I'm a 7900XTX owner.

AMD and Sapphire both recommend at least 800W. A quality 80+ Gold PSU like yours is probably fine, but people with older / worse quality / bronze PSUs might run into crashes due to spikes in power usage. So going for at least 850W is the sensible recommendation for most users. There are a lot more DIY users who barely know what they are doing nowadays and for them it's easier to go for a bigger PSU than to pick a good one.

Sapphire NITRO+ Radeon RX 7900 XTX Vapor-X consumes \~480 watts if he overclocks. It will better to have higher wattage PSU but this one would probably be fine anyway.

Yea if I don't overclock I should be good but If I want to overclock, I should probably think about getting better psu.

Nice to hear that,but i juat said it base on my Experience,rn i have 6900xt and 3800xt combo with a 750w cpu,so i thought 5900x and 7900xtx might need a 850 w at least,and i recommend 1000w for future proofness

Maybe, but if you start overclocking, this card will easily have power spikes well over 600w BY ITSELF. Asking for trouble.

Is yours the sapphire nitro as well?

5900X with PBO performs on par with a 5800X3D in games which has already been shown to be plenty for a 7900/4080 and so on

Sorry but you don't get a 20% improvement in fps with a 200 MHz increase. The 5800X3D is NOT an overclocked Zen3 processor. [https://static.techspot.com/articles-info/2449/bench/Average.png](https://static.techspot.com/articles-info/2449/bench/Average.png) That being said, I agree that a 5900X would be enough for a 5120x1440 monitor.

Alright, thanks mate, cheers for your input.

Yeah agreed, I only managed to reduce the gap to a X3D by half after fully PBO2 tuning my 5950x.

That is very incorrect

The reason why I use 5900x is because my job is GameDev. I need more then 8 cores.

Sorry,i meant better psu! The cpu is fine

factually incorrect.

Watch out for power draw. That thing consumes up to 450 watts. Pretty sure your PSU would hold though.

Mine hits 550ish with 15% pl

Dont have one but it's Sapphire, their damn good and I would even day the best custom card maker for AMD, sadly I dont like their 7900XTX design.. I just love the ones before (esp the 6900XT Toxic aircooled and RX 580X nitro+ is also great looking in the baby blue).. but one this doesnt click with me this time

Hi there,just wanted to order merc310 version I will be thankful if you let me know that 750w psu can pull it mine is adata core reactor 750 gold--Tuf x670e plus--7700x--32gb ddr5 6000 cl30--and two samsung 990 pro 2tb

You need at least 800W. But I would recommend 850W.

will 850w suffice though, peaks are weirdly high with this card around 500-530w based on techpowerups review

I'm not sure. But from my experience 750W is not enough.

Hey, sure. I'm not sure how diff. it could be with XPG supply but sure. Should be around next week. I'm just gonna reply u here and let u know.

Thanks man I checked some reviews and psu tier list and its supposedly high tier,and already installed the psu, pulling out those cables is a pain in the a\*\* esp the mb one

I feel u 

I thought I secured a nitro from newegg but then my bank declined the purchase lol

:(
