Re: 6900XT causing PC to reboot while gaming

Wanna hear something funny? ( for you not for me)

After 2 weeks of no crashes i changed to a new case and guess what, i had another crash. What does the new case have that the otehr doesn't ? More fans.

This is where AMD loses most of its clients, their soft is garbage. Excuse my agressiveness but when you pat 2000$ for a **bleep** silicone you expect it to "Just work", not run around and around like ian a **bleep** circus until something( most of the times you don't even know what) fixes your problem, if it ever.

Shame on you, AMD

Re: 6900XT causing PC to reboot while gaming

Are your games crashing or entire Windows will reboot? Is your Eventlog filled with WHEA unrecoverable errors just before crash? When i have moved from 1080p to 1440p gaming, my memory become unstable at 3600 Mhz and computer has started to reboot. Undercocking memory to 3200 Mhz has solved my problem, but of course it can be different case with you.

Re: 6900XT causing PC to reboot while gaming

I've not seen WHEA errors, but I might not be looking in the right place. I believe my Corsair memory is 3200 anyway.

I've had some minimal feedback from Scan, too, and they've got it working on a 4K monitor with the latest BIOS, but that is not the 1440p 60Hz monitor that I run at home.

I would ask if anyone believes that running the benchmark (3dMark Time Spy) at 1440p 60fps but rendering it at 4K would likely be a different thing for the GPU/CPU/MB/Mem to manage than simply running at 4K straight.

I do know that 1440p is not always perfect ¯\_(ツ)_/¯

@x6205I've read your story now ... you shouldn't have to limit your PC ... it should run at stock levels ... it's not acceptable.

Re: 6900XT causing PC to reboot while gaming

Well, i understand your point of view, but why should i stress myself and spent whole summer with troubleshooting. Tinkering with BIOS or DRAM Calculator or blaming AMD for bad drivers, Asus for bad BIOS or AMD for bad AGESA or whatever. Memory downlocking was propably easiest way how to solve my specific problem.

Other option i have is replace RAM with even more expensive model and if it will not help then what? Maybe it's bug in AGESA, maye in drivers. Since then i have updated BIOS so maybe i will re-test it at 3600Mhz again. Anyway, difference between 3200 vs 3600 Mhz is so small, that it's almost irrelevant to push RAM higher.

Re: 6900XT causing PC to reboot while gaming

@Cmdr-ZiNI left my PC on for 3 Days on a fresh install, had no issues in Windows 10. However, that was the Basic VGA Driver. The moment I installed AMDs proprietary wares... GPU Locked up, or Blank Screens. I could see quick tempered people going NUTS at their builds.

 

I've been on Linux since June 2021. I've had no issues with this card. I decided to dual boot into Windows 11 when it was released. I have to say that DCOM thing is NOT working very well on the new OS. I tried watching a video and the moment I skipped a few scenes or fast fowarded n my screens all went blank.

It's software, it has to be. I've been running fine on POP OS a variant of Ubuntu Linux, completely normal and the Basic VGA ran normal without fault.

Everyone seems to be racking their brains out thinking it's hardware. I did even think that @RaiJinRoh  PSU or Power Requirements had something to do with it. I have a 1000w PSU and an i9. My Nvidia card worked fine, however AMD cards are renowned for being very power hungry like their CPU counterparts.

But no issues on Linux. - Are these forums monitored! Like is there anyone from AMD that actually reads these forums? What do you have to do to get the attention of a mod or AMD Developer? Post a nude?? These forums are annoying and several people have contacted AMD including me and they are refusing to acknowledge the problem. 

I did checkout TenForums, a few people were complaining that Windows Sucked and kept rebooting on them, after I asked what GPU card they were using 100% of them said AMD.

https://gpuopen.com/  I've had a look here.

https://github.com/GPUOpen-Drivers/AMDVLK 

 

I'm hoping someone else that's fairly tech savvy or has developer/software engineering skills, can test out my theory and install a copy of POP OS Linux on perhaps a spare hard drive or partition or even a USB stick install.

One thing, I did notice however on Windows, if I disabled my wallpaper and all visual effects I wasn't plagued by the reboots. Whilst on idle. I do remember that from Windows XP, Microsoft changed the way the Graphical User Interface was drawn by the OS and on Linux the UI is less graphically enhanced, depending on which GUI your using as Linux has a fair few choices.

 

Does anyone have a PSU higher than 1000w? and still plagued by the problem.

I suppose another option would be to port the Linux drivers over to Windows, but Windows Requires Signed Drivers. You can override that, I guess. But how many security overrides must you enable just to use a graphics card. It's like your literally fighting Windows's Subsystems.

I know reverse engineering and publishing the source would be illegal but porting the Linux drivers seems like feasible option, though the interface architecture is completely different. Although being sued by AMD, would at least put me face2face with AMD.

https://www.overclock.net/threads/official-amd-radeon-rx-6800-xt-owners-club.1774300/page-9  - Some people here are suggesting to reduce the power consumption of the card by under clocking it.

 

One thing does baffle me. Not everyone is affected by this. Some cases, the system runs fine. Makes me wonder if it's a GPU BIOS flaw. As different manufacturers have different BIOSs https://www.techpowerup.com/download/ati-atiflash/

Although if your card or system crashed or hung during the update. Unless your card has a dual BIOS, that would be the end of that card, unless you wanna resolder a new BIOS chip to the card, though you'd need some master skills for that feat of engineering.

Re: 6900XT causing PC to reboot while gaming

@Tazryder 3 days may not have been enough but depends on the usual frequency of the issues you're having.

You say you have an i9 CPU so you probably don't have the random reboot issue many Ryzen users are having. Mine I'm putting down to CPU not being as stable as others, since replacing it I've had no issues for just over 2 weeks running constantly and I hope I don't again. My memory has been pulled from the QVL listing I wonder if that was a contributing factor.

Yours sounds more like a GFX card issue, it could be software. I doubt it's power draw, 1000W is fine assuming your PSU is in good condition and setup correctly, I assume you're running 2 separate power cables I can't remember all the previous posts. AMD graphics cards use a lot less power than their competition this gen BTW, but it's not a power issue.

If you want help from AMD the forums aren't the the best place it seems, email their technical support.

It might seem like everyone has the same issue but there's lots of causes and people on the internet can miss things so you need to take what you read with a grain of salt until you can confirm it yourself.

If there was a mass issue there might be a statement but it's more likely lots of different issues that would need individual technical assistance and  forums aren't the best place for that.

When you installed AMD's wares what did you install, was it driver only? I have had the drivers glitch on install had to DDU and resinstall and they were good since.

Do you have any overclocking software installed like MSI Afterburner?

As long as your drivers and Windows and everything are up to date then I'd contact your graphics card manufacturer and ask them.

If they recommend a BIOS update I'd do it. A long time ago I messed up a BIOS update on a GFX card, I was able to boot with another graphics card and flash the messed up one in windows, I doubt this will work these days you'd probably need to RMA.

However these days as long as you follow the instructions to the letter a BIOS update is pretty easy to do and very reliable as long as there's no power outage you'll be fine. Check with the GFX card manufacturer first.

I wouldn't be surprised if you need to reinstall or update something or need to RMA your GPU. It's hard to say the cause without looking at it more closely.

Re: 6900XT causing PC to reboot while gaming

Some of the suggested fixes here, while they might have seemed to work for some people don't appear to be getting at the root cause.   I installed my card, things generally worked and then I decided to run 3dmark Time Spy to see how it would do.  After only 10-20 seconds in, the system shut down.  And when I say shut down, the red Radeon logo shut off, but the LED's on the RAM were still lit.   So it wasn't a complete power shutdown, as it turns out it appears to have been the 12V supplies.  My PSU is a Corsair HX750i and should be plenty for what I have installed in the machine. It's got a Ryzen 5800x at stock frequency/voltage, 32GB 3600 DDR4 and a 2TB PCIE3 M2 SSD.   None of that should come anywhere close to the limit, even if the card were to draw 500W.  Then I read a comment somewhere on Reddit about split rail supplies.   In my case, I can select this in the iCue software.  When I loaded that up, sure enough I had it set to split rails. (not intentionally)    So with split rails, that means the over-current protection limit for each of the two rails will be lower.   The problem is, I have my power connectors to the GPU coming from one of those rails.   Once I rebooted with that change, the shutdown problem was resolved.   I'd suggest that people check this on their PSUs.   So no, you don't need a 1000W+ PSU, you just need to allow it to supply the power it needs on one rail.

Re: 6900XT causing PC to reboot while gaming

@sebakke yeah you want to use 2 separate power cables for your GFX card and put one on each rail. I'm pretty sure this was mentioned earlier.

Although your stability may of improved keep an eye on your system closely over the next couple of months because there's instability issues with the 5000 CPU series too and they sound a lot like how you described.

I wonder if there's issues with memory speeds over 3200 Mhz or the system running the fabric too high. I too have a 5800X and 3600Mhz RAM, infact it's my second 5800X it solved my issues perfectly for 2 months before also dying.

There's something unstable about this platform.

Re: 6900XT causing PC to reboot while gaming

My 5800x has been perfectly stable since I built it 9 months ago.  I've used it with a 5600xt and 3060 without any issues.  But either of those GPUs are relatively low power, so haven't stressed the system.

Re: 6900XT causing PC to reboot while gaming

@sebakke that's good to know you where stable with a 5800x CPU and 3600Mhz RAM prior to getting your graphics card.

Maybe I'm just unlucky to get 2 dud CPUs, but it does make you wonder, especially when a lot of people say Ryzen has troubles with high speed memory.
