Hello here is a tip for the 6800xt and 6900xt graphics card if you have crashes in games.
If you own a VR headset or have more than 1 screen connected then remove the VR and your extra screen so only your primary screen is connected.
I own the 6900xt and pimax 8kx vr headset and my games also crash all the time, BUT when i unplug the Vr headset two usb cables then the games do not crash anymore.
So i think there is some kind of HDMI/usb Vr kind of bug.
my story
i did not play much vr with the new 6900xt yet but i had 0 crashes in VR... but if i start a non vr game with the vr headset connected the non vr game will crash withing 5-10-60 minutes no matter what.
And its also like when i play a non vr game with the vr headset connected its like i dont get as many fps as when the vr headset is not connected to he computer.. So something is clearly wrong that a vr headset that is not "on" but in standby/sleep mode effect other things. I did not have this problem with my 2080rtx nvidia card.
pps.. the computer do not crash/turn off when i do stress test, 3d tests or burn in tests and torture tests of the hardware.. it only happen in non vr games when the pimax 8kx is connected. So its not a heating problem of my system its rock steady if i remove the vr headset.
my specs
windows 10 64bit
32gb ddr4 ram
6900xt
5900x cpu
2xm.2
1x7200hd
1x water cooling ( closed AIO system )
1000w rog power supply
Acording to my calculations the computer need like 650w - 750w so its not a power issue. And as said if i remove the vr headset the computer is rock steady and no crashes.
