Saphire rx 6800 16G OC + Ryzen 5 5600x Blackscreen crash

Hello Guys,

So I've built myself a new computer for the first time (So please have mercy on me if i dont get things instantly), and i've experienced a lot of black screen crashes while playing some games on higher settings.
So far i've had crashes while playing CoD: Warzone while turning raytracing on and Cyberpunk on Ultra and sometimes even on medium settings.
I get a blackscreen, the sound gets stuck and the LEDs on mouse and keyboard begin to flicker. The Monitor doesnt seem to get a signal from the PC anymore.
After that the computer doesnt react to anything and the only way to stop it is a hard reset by pressing the power button.
I've tried reinstalling the drivers, changing the voltage on the GPU and making a clean reboot. None of that worked.
I've also run some diagnostics with Furmark, GPU-Z and LinX. None of the values really seem to be out of the order for me. Also i can run Furmark on high settings without and problems and LinX also gives me back good results without crashes (Even if both run at the same time).

Specs:

CPU: Ryzen 5 5600x 6-Core 3,7 Ghz
GPU: Sapphire Radeon RX 6800 16G OC
MBO: Gigabyte x570 Gaming X
PSU: Be Quiet straight Power 11 750W
RAM: 16GB G.SKill Aegis DDR4 3200 Dual

I appreciate any suggestions to what i could try to fix the issue,

Thanks a lot in advance!

hi,

1. update your BIOS to lastest
2. do a CMOS reset (and leave everything on auto)
3. test again

4. enable "above 4G decoding" in BIOS
5. test again

6. increase powerlimit by 15%
7. test again

Laptop: R5 2500U @30W + RX 560X (1400MHz/1500MHz) + 16G DDR4-2400CL16 + 120Hz 3ms FS

Re: Saphire rx 6800 16G OC + Ryzen 5 5600x Blackscreen crash

So i've tried the first 2 methods and now i encounter a different kind of crash.
Now it seems only the GPU is crashing. I get a blackscreen but the sound stays for a few moments and the LEDs on my mouse and keyboard stay on.
But now the compuiter crashes instantly upon entering the game...

Could you tell me which power limits i have to increse (which lines in the BIOS) ?

It seems to go the right way, thank you

power limit in Wattman (in AMD Driver)

btw - if game crashes instantly:

run DDU in safe-mode to clean old driver - then install 20.12.1

Re: Saphire rx 6800 16G OC + Ryzen 5 5600x Blackscreen crash

ok i reinstalled the drivers and increased the max power by 15%.

Its stable if i turn down the frequency to 85 - 90%, but as soon as i run games on full capacity it crashes after a few minutes in.

Re: Saphire rx 6800 16G OC + Ryzen 5 5600x Blackscreen crash

is it the pulse or the nitro card?

maybe card is broken.

do you run MSI Afterburner? or any app that gives an overlay?` (Rivatuner, steam overlay, uplay overlay etc)

neither of those, just Sapphire 16GB Radeon RX 6800 16G
Is there any way to find out if its broken?

 

I tried using MSI afterbruner in order to do diagnosis and while i play cyberpunk i have to run steam in the background

1. disable Steam Overlay in settings for Cyberpunk (then test with Cyberpunk)
2. also close MSI Afterburner + RivaTuner (because its another overlay that can do weird stuff)

you can test your GPU at a friends PC - or you simply RMA it (i best hopes)

here some other fixes:

A: do a CMOS reset - and leave everything at "AUTO" in BIOS (no XMP etc)
B: use DDU in safe-mode to clean old AMD and/or Nvidia driver
C: do a fresh install of Win10 20H2

I'll try all of that tomorrow.

What does RMA mean?

Also i've just read a thread about it being a common problem with the 6800/6900 suddenly having power spikes and melting the PSU...

Thanks a lot for your help so far!
