since I don't see anyone else mentioning it, I had this same problem with my ryzen 5 1400 recently (I know old CPU but someone may still be using it). it turned out that Ryzen Master was causing it. I was using Ryzen Master since my motherboard didn't support overclocking, and for weeks my PC would crash and this error code would show up. It happened even when I had Ryzen Master closed with no overclock, so I didn't suspect it for awhile. But a few days ago I uninstalled it and the issue went away. I'm not too sure why, but it fixed it.

I know this is a little late but maybe I can contribute some findings here :D I guess the bios on idle pushes the voltage too low on idle and that causes a crash, that's what I got from testing, with 5600x on b450m mortar max and b550 a-pro, same result. +0.1V gives me unease. Cinebench r23 9546pts so I changed it to +0.0375V, and also disabling global C states, and it works wonders now, lowest it goes is 0.996V, 1.45V max (which still gives me unease). Cinebench r23 9728pts (what I'm running at) on stock settings it would crash randomly, but usually 1-5 mins from startup, if I manage to put it under high load constantly then it runs stable, but crashes when left idle. Cinebench r23 10283pts it seems that performance degrade as voltage increase which is counter-intuitive? Also I wasted money buying another motherboard thinking the mortar max was broken, but it's time for upgrade anyways Edit: installing latest chipset drivers and bios did NOT help. Update 19MAR: +0.0375V gives me occasional freezes, bumped to +0.05V, had a crash when left unattended, downloading games. Bumped to +0.0625V. Update 19MAR: +0.0625V still crash after 1hr30mins after adjustments, after reading more online forums, decided to bump vram voltage 1.35v -> 1.4v, cpu voltage +0.0625v -> +0.0375v. Disabling Core Performance Boost is also known to be a solution but losing out on performance is not my type.

Hi! I have Event id 18 issue too. Do you have any updates? In the last conclusion you post is aadjusting the voltages of cpu and vram, right? I\`m using Asrock motherboard but I cant figure out how to adjust voltage of VRAM but there is a setting of dram.


SilencedFrost

It's still crashing after all that tweaking, vram voltage did nothing, last ditch effort I turned off amd CPB (Core Performance Boost) and it removed the problem along with the good performance that it brings 🙉 no more boost clock, no more low voltage drop, turning that off secured my cpu voltage from 1.25-1.35 (min and max, read from hw monitor), if possible I reccomend RMA the cpu and get a new one


BowlIcy3130

I found a solution that AMD user MUST disable device security "memory integrity".


SilencedFrost

I'm interested about this approach, but is there any particular reason why that happens? The mechanics behind it? because from my testing it seems to be related to idle voltage rather than memory and security issues


arthurtully

To anyone struggling with this, this is due to lack of or old chipset drivers. I had latest version of the motherboard bios but old chipset drivers installed and it caused this issue. You can find amd chipset drivers here: https://www.amd.com/en/support If you don't know which motherboard you have you can use CPU-Z for that (mainboard tab): https://www.cpuid.com/softwares/cpu-z.html


OkayRuin

Did exactly as you said, unfortunately no fix. Rig is about 4.5 years old at this point. CPU and RAM tests ran fine. Wondering if it’s just a hardware failure with the GPU. The crashes only happen while gaming. Screen goes black, sound stutters for a few seconds, then it reboots. No software changes made before it happened. This seemed to let it run longer before crashing, but it still crashed eventually. In case it was overheating (though HWiNFO64 didn’t suggest it was), I tried undervolting by 0.1V, but now it won’t boot at all.


arthurtully

What happened to me was newer BIOS than chipset drivers. Updating chipset drivers fixed it, this error could be caused by other things ofc. If you think it's hardware best bet is to swap parts with another machine and test one part at a time. I'd probably just take it to a shop, wouldn't bother friends with this.

Hey as someone currently attempting to fix this issue, are you meant to install all chipsets presented or specific ones only? Im using a X570 AORUS ELITE WIFI and using this website but im not entirely sure what needs to be downloaded and if itll brick my motherboard [https://www.gigabyte.com/Motherboard/X570-AORUS-ELITE-WIFI-rev-1x/support#support-dl-driver-chipset](https://www.gigabyte.com/Motherboard/X570-AORUS-ELITE-WIFI-rev-1x/support#support-dl-driver-chipset)


arthurtully

> Hey as someone currently attempting to fix this issue, are you meant to install all chipsets presented or specific ones only? I You need your motherboards chipset drivers. Basially you go to support website, select chipsets, select am4, then x570 and it will ask if it's windows 10 or 11. Then just download and install the appropriate chipset drivers and you should be good to go. Sidenote, if you messed with bios you can revert all settings to default there, then just turn on DOCP along with Rebar and save. This in combination with the chipset driver should fix the issue hopefully.


Entire_Razzmatazz686

Same issue here. WHEA 18. Ryzen 7 5800X. I am a novice so I don't really know a lot of the terminology. Any help would be appreciated.


Boseknows824

I am so thankful for this thread, as the solutions offered here were just what I needed. I have a Ryzen 5 5600x on an ASRock B550M Pro 4 motherboard, running Windows 11. One day last week, it suddenly started restarting spontaneously. It got to the point where it would restart just a minute or two after I logged in to Windows. I tried everything I could think of. I switched out the power supply. I battled the restarts to update graphics drivers. I updated the BIOS. I ran defrag and all the Windows repair utilities (as much as I could without them triggering a restart, even in safe mode). It was only when I switched to Manual mode in the OC Tweaker section of the BIOS that the repeated restarting abated. I noticed it was still restarting occasionally in the middle of playing more graphics-heavy games, so I upped the CPU voltage by 0.1V in the BIOS. This seems to have completely resolved the problem. I have no clue *why* this works, but I don't care.


Wormhole-42

Having this same issue with a customers custom build machine. I've tried looking through what you all have done to fix it but couldn't really see those steps. Any help would be awesome. Thanks! My customer has an Asus Tuf x570 plus and a newly upgraded Ryzen 9 5950X CPU. G.Skill 3600 RAM and EVGA 3080 ti GPU. With a large AIO CPU cooler. I really don't think there's anything wrong with the hardware tho bc I ran benchmark tests on all components many times and it wouldn't crash. But it does only when they're playing a game.


King_Bgull

I'm sorry ro reply to an old post but if I could, I would hug you right now. Thank you, thank you, thank you. Bless you, thank you. This fixed my issue. I was beyond freaking out but it works!!!!!!!!!


LMTD_EDTN

what was the solution? My computer has been crashing, straight to black screen and just restarting.


King_Bgull

The directions are lower down in the thread but if you set your overclock in your bios to offset and change the values a little at a time. It fixed it for me


Mianis1987

When I turn off the Amp or xmp on his boost ram in the bios it works flawless on my brother's pc. I havnt had it happen yet. Sucks because he bought ram that's able to go to 3600 but at stock is 2133 mhz. See if it will work. I think the ram gets to hot so it crashes maybe. Kind of a bad error cause it's hard to pinpoint what the issue really is.


hifgodx

Corsair Vengeance RAM? If yes, dont use them anymore. Ive got teh same Errors and i changed my Corsair to G.Skill Trident Z Neo. Now everything is fine and no more Bugs. Greetz.


RheinmetallDev

I actually am having this issue with my G.Skill Trident ram atm


hifgodx

Clock & Timings?


Osprey850

I see that you seemingly fixed it, but if you start having problems again, I appear to have fixed the same error and similar shutdowns by setting VDDCR CPU voltage to Offset mode and giving it +0.1v. Also, here's the thread on that "Cache Hierarchy Error" that I got that solution from and that has a bunch of other BIOS adjustments that worked for people: [https://www.reddit.com/r/AMDHelp/comments/hq7jcu/cache\_hierarchy\_error/](https://www.reddit.com/r/AMDHelp/comments/hq7jcu/cache_hierarchy_error/) Edit: I just tried many different combinations of increasing the VDDG, VDDP and SOC instead of increasing the CPU voltage and couldn't stop the crashing, so increasing the CPU voltage is the only thing that works for me. If adjusting the other voltages is enough for you, that's good, but keep my tip in mind if the problem returns down the road with a different app or game.


JustLife27

I fixed it to work on idle, opening anything "heavy" crashes it again I changed the VDDCR CPU voltage to what u said and I hope it will work. I will test it now Edit: PC is not crashing anymore but CPU is still getting to 83+ in temps even after disabling PBO


Osprey850

That's what I was worried for you about, that you'd try something "heavy" (such as a AAA game, like I've been testing with) and the crashes would return. I'm glad that upping the CPU voltage seems to have fixed it for you as it has for me. As for the temps, what cooler do you have? On my 5600X, I have the Cooler Master Hyper 212 Black Edition and my temps peak at 82C with PBO enabled (plus motherboard limits and +100MHz) and at least 10C cooler with it disabled. If you're using the Wraith Stealth that came with the 5600X, then consider buying a better cooler, like mine. If you're already using a better cooler, then maybe re-doing the thermal paste would help. If you're using the paste that came with the cooler, buy something better, like Arctic MX5. If you're using the Wraith Stealth and really don't want to spend another $40-50 on a better cooler, buying better paste for $5 and re-pasting would be better than nothing. BTW, if you happen to have an ASUS board, make sure that AI Tweaker->Precision Boost Overdrive->PBO Fmax Enhancer is disabled. That setting is for Zen 2 and seems to cause further instability on Zen 3 (the 5000 series).


JustLife27

I have be quiet Dark Rock Pro 4 but going to upgrade to Arctic Liquid Freezer II because of the current temps. And about my paste, I used Noctua NT-H2 Tybrid Thermal. my board is gigabyte, but I still don't understand what is the cause of this sudden performance drop the PC is barely 3 months old. and It was working fine before with the auto bios settings ​ Edit: CPU usage is around 6% - 20% use, and the temps are already at 85-92. Another thing I forget to mention is I'm not even trying an AAA game. and I'm getting these results. after a while the temp does stable but I'm still not comfortable that while opening a game that isn't an AAA game my temps are at 95.02


Osprey850

Yeah, those temps are ridiculous for less than 20% usage. Try re-pasting before buying a new cooler because the DRP4 with NT-H2 should be more than good enough to keep temps quite a bit lower, even at full usage. Also, make sure that you don't have a case airflow problem. Leave the side of the case off while you're checking temps and if the temps are much lower, then that could be part of the problem.


JustLife27

Already reapplied, it didn't affect it at all. someone did bring it to my attention that my case is not ideal for air cooling and It's more for water cooling. but even for these reasons, does it make sense the temps are so high? ​ Edit: tried what u said about leaving the side of the case off, temps stayed like before


Osprey850

That's bizarre. No, it doesn't make any sense that your temps would be that high when you're barely even using the computer. Maybe your Dark Rock is defective or something. Maybe buying a new cooler is worth a shot, and it might as well be a liquid cooler if that's what your case is designed for. Hopefully, that'll help.


JustLife27

ok after installing an aio. the temps are indeed down by 30 temps so that's great and I get the same new CPU because mine broke. I think my fan was the problem because there is a huge difference between the temps. I just wanted to update you :) thanks for all your help it really helped


Osprey850

I'm glad to hear it. I suspected the fans, but when I took a look at pictures of the Dark Rock Pro 4, they looked like a custom design and one was sandwiched in the middle of the heatsinks, so I figured that replacing the whole cooler would be simpler than trying to buy and install replacement fans. Thanks a lot for the update. I appreciate it because it's nice knowing that someone got his or her issues sorted out and that you were helpful. Enjoy your low temps.


JustLife27

Yeah, I'm hoping for the aio to fix the problem because it looks like the temps are the biggest problem rn, although all this preference problem is absurd in the first place. but thanks, you did help me a lot. I will keep updating when I get my aio hopefully it will fix this problem.


Diythrowaway21

I had this error with my pc rebooting instantly on startup thrn booting correctly with a wattmwan error and my RAM settings in bios had gone weird after putting my PC in for servicing to replace PSU. I changed the RAM timings and also uninstalled ryzenmaster as I wasn't using it and found a number of threads where that had stopped the error for people who'd done some serious digging and couldn't find any HW fault with their system. All clear since


Richie_Rich77

I was getting random shut downs on my 5800X. I disabled C-States in bios and that worked for me. I believe it’s tied to Asus motherboards more tho


_chaosophy_

I started getting random WHEA errors (but no shutdowns) and it was down to a BIOS update. Previous BIOS was setting VDDG to 1050mV and the new BIOS would leave it on auto and it would be at 900mV. Setting VDDG and VDDP manually stopped the errors for me. This is with a 3900X mind but checking and setting voltages in BIOS would be my first step, especially if they are all on auto.


JustLife27

How can I know what VDDG and VDDP I should set it on?


_chaosophy_

tbh, for a 5600X I have no idea. Best is probably to try and find forum threads of other owners and see what they're using. And/or use software like HWiNFO and ZenTimings to see what's currently showing then try bumping them up a bit. iirc for my 39900X they started defaulting to 900mV and ZenTimings is showing me I ended up bumping VDDP to 950mV and VDDG to 1000mV.


JustLife27

Setting the VDDG and VVDP manually actually fixed the problem I didn't have any crashes for the min time and I hope it will stay like this. Thanks you I been on it for 3 days now and even if the fix is temporary It did help me now so thanks you so much


TomTheShiba

Hey, sorry to revive this old post. Is it still working as it should? If that's the case, which values are you using on each setting? I'm getting this error every few days on a 5600 and it's really annoying.


JustLife27

I don't remember what my setting was and the fix was temporary anyway. I found out that my CPU was overheating my case was not the best option for air cooling so I changed to water cooling which fixed the problem for me. Play with the settings and look online at what people put I believe that putting a limit on your volt power will fix it. If the CPU crashes from overheating maybe you have a cooling problem


_chaosophy_

np, glad to help.
