RX6900XT causes pc to shutdown

Hey guys,

 

I have seen similiar topic here, which for some reason was closed...

I purchased RX6900XT today this version https://www.gigabyte.com/Graphics-Card/GV-R69XTAORUSX-WB-16GD#kf, swapped with  my RX6800 which had zero issues

Now, whenever I try to load any type of benchamrk, Time Spy or Fire Strike, PC just shuts down with some RGB lights still on.

I tried: updating MOBO bios, resetting it to stock settings without any OC

Uninstalled driver using DDU, installed the latest version Adrenalin 21.11.3 Optional, then using DDU again, tried Adrenalin 21.10.2 Recommended (WHQL), no joy, same issue.

I thought it might be PSU (EVGA850GA GOLD), but saw others swapping theirs for 1200W and issue persists.

Unfortunately I found no solution in this topic as well : https://community.amd.com/t5/graphics/6900xt-causing-pc-to-reboot-while-gaming/td-p/438749

Any solution? Thanks..

Re: RX6900XT causes pc to shutdown

I am having the same issue my 6900 is on a liquid cooled setup so I know I’m not overheating and my psu is an evga g2 1300 so not overloading … I’ve tried turning of resize bar and enabling csm in bios with no luck … are you by chance running windows 11? Because I didn’t start having issues till I installed win 11

Re: RX6900XT causes pc to shutdown

Actually I was thinking about upgrading to W11, but wont now lol

Running W10 which I installed like 2 months ago, dont think reinstalling it gonna help.

It's so frustrating, I bought this card for benchmarking purposes mostly but still...

Weird fact: card almost can finish Time Spy's graphics test, but shuts down PC when trying to run Fire Strike instantly.

Re: RX6900XT causes pc to shutdown

Update: I was running all benchamrks while monitoring it with MSI aferburner. I disabled it and I was able to run benchmarks I was not before: Time Spy and even Fire Strike was not even starting but causing PC to shut down instantly.

Then I did a small OC, PL 15% and max Core clock 2700 and symptoms were same. I refuse to believe that my card is not able to run at these clocks.

 

I ran Time Spy Extreme stress test, 20 loops roughly 15min and no issuesIMG_2929.JPEG

Still feels it is not 100% stable.
We need better driver AMD.

Re: RX6900XT causes pc to shutdown

I think I found a solution through these forums… set Radeon chill fps min to 140 and max to 180 , go to tuning and set the 3D clock to min 2000 max 2200 , Atleast in gaming this seems to have solved the issue

Re: RX6900XT causes pc to shutdown

Soo, after all, it just was PSU...

Power spikes of 600+ watts, which EVGA 850 just cant handle

Upgraded to 1000W and all works really really well

Re: RX6900XT causes pc to shutdown

I can confirm that...had a similar Problem because i used the daisy chained standard PCI-E cable from my HX850i.

OCCT Powertest causes the PC to reboot instantly and sometimes it rebooted while gaming.

Works fine after i changed the powersupply of the GPU from one  to two cables...
