Asrock 6800 Challenger Pro Black Screen

I have a problem with my GPU Asrock 6800 Challenger Pro.
During gaming, my monitor go black, the GPU fans sometimes swing at full speed or remain at the same fan level, all lights are still on, the audio cuts off 4-5 seconds after that happens, then the lights turn off. I can't do anything except hard reset the PC.
That happened often with PlayerUnknown?™s Battlegrounds, shadow of the tomb Raider.
I tried with everything to find a solution for this issue.

Hi guys,

Same issues here as described by Lakritz93. Tried to upgrade to vBios L04, but it did not give a message of 'success'. Instead just rebooted of itself. In windows 10, I started GPU-Z, and it stated that it was still on the L02 version. Everything still working, except heavy gaming and 3Dmark stress test, as it results in even more frequent black screen, reboot loops and sometimes fans going berserk.   

AM4 Agesa 12.0 and later (Asus x570 E-gaming here), Resize BAR and latest Adrenalin drivers (21.4.1 and 21.5.1) seem to (adversely) affect the occurrence of the black screen fan issues and instant reboot (at face value from own experience and reading forum posts of other 6000 series owners.

And having a 3900xt CPU (instead of 5000 series) and BAR enabled may mess up things further.

Can you guys give a more elaborate explanation of why these symptoms might occur, and if possible, provide GPU bioses to Techpowerup's database?

Since you are already actively suggesting customers to upgrade the GPU bios, this might be a lifesaver for some with single vbios (as is the case with rx 6800 challenger pro), and preventing possibly unnecessary RMA's.

Take care guys

Dear Solon,

Flashing the vBIOS while system is unstable might cause the behaviors that was described.

For the further assistance, please contact technical support by filling out the form in the following link:

Great Bios update (L04)! My pc build seems to run more stable now. Thanks!

Small side note on increased stability: Instead of daisy chain I now use two cables from (Corsair RM850x) PSU to GPU and I also added an extra 4 pins from PSU to CPU (8 + 4 pins on motherboard)

Thanks again guys

I Attempted to update Bios but my card no longer registers on my MB so the Bios update for the Card Failed.
