Re: 6800 XT and Samsung Odyssey G9 periodic black screen system crash

I'm using DisplayPort. Currently experimenting with the 20.11.2 drivers installed without Adrenalin (https://community.amd.com/t5/graphics/radeon-6800xt-black-screen/m-p/426353/highlight/true#M68254 and https://www.youtube.com/watch?v=IhBLqTVxcBM). The system didn't crash all night (~8-9 hours on). I will continue testing today.

May I know what's your system specs?

What's your GPU usage during heavy load or gaming?

@mypg0306 

Depends if you limit or not frame rate...

but around 150 W was the max I have seen. To be honest I really don't care about power consumption. As long it's stable.

Re: 6800 XT and Samsung Odyssey G9 periodic black screen system crash

I mean is GPU running 99% all the time when gaming?

@mypg0306 

If you don't limit the FPS's of the card, that's going to be the end result yes.. most likely.

Previously most games would be CPU bound and the big GPU cards would not be able to process much data, hence not going to 99%.... or also, if you were using VSYNC and using a beefy card, when using 60Hz resolutions, that would effectively limit the framerate the GPU is required to produce... meaning the GPU would never or unlikely go to 100%.

Without those problems in the way anymore (CPUs and PCIe has improved quite a bit), the GPUs are able to produce huge amounts of FPS... until they reach 100%. Not that you need that... but if you don't tell them to stop (at a certain FPS rate) they will just as much as they can.

There is an option on the Adrenalin drivers to limit the FPS in general... I have a 120Hz monitor, so my limit is that. Above that I don't really see any benefit... so there is no reason for that.

Hope this helps you understand a bit more.

 

Note: If you are indeed limiting and still see 99% GPU usage, then you might have a problem. But be sure to understand the game requirements before assuming you have a problem.

Re: 6800 XT and Samsung Odyssey G9 periodic black screen system crash

OP here again.

Despite the non-Adrenalin driver install method, which was showing stability for a day or two, I am continuing to experience full system crashes with a blank screen. The monitor (the G9) remains "on" (pixels are on) but show no image. I am almost entirely sure that this is a Windows driver issue and not a hardware problem with the card because I dual-boot this system with Linux (Arch, latest available kernel) for work and have full stability, no crashes. I am on the verge of returning this card and hunting down a 3080 or 3090 because having my entire system crash randomly is a horrible experience.

Re: 6800 XT and Samsung Odyssey G9 periodic black screen system crash

I have the same problem like you.

AMD RX6800XT + Odissey G9  need to restart 4/5 my computer to have a screen of windows (connection ok on Display port 1 but bblack screen).

I have called SAMSUNG and after 1h of diagnostic together they told me call AMD there is a problem with the game card
