I've had grey screen + blue lines crashing with my 6950XT  for my entire time I've owned the gpu (1.5 years). I've read multiple people with the exact same issue with different architecture GPU's - some RDNA1, some RDNA2 and the issue even exists with RDNA3. I've done all of the run of the mill things like disabling MPO, reinstalling windows, clean driver installs and even flashing  custom BIOS. Nothing fixed it. The thing all users with this issue had in common is high refresh rate and / or 10 bit color multi monitor setups.  There's clearly a bandwidth issue or some kind of display protocol issue that causes these crashes and they happen at the most random of times. 

So let me get to the point - the issue is 100% GPU related. Many people speculate that it might be a Chipset driver problem or an unstable BIOS configuration but no - I am 1000% confident it's the GPU. How you ask? Because 3 months ago I bought a 4080 super and just swapped my 6950 XT with it. No windows reinstall, no difference in my BIOS configuration, only reinstalled AMD drivers with DDU -> installed Nvidia drivers. SAME.EXACT. SETUP. And I'm yet to have a single issue with grey screens/black screens/ crashes etc.

So yeah.. wanted to put that post out there in case people were still searching for "grey screen blue vertical lines". You should know that your GPU's the problem, and this has been a problem that's existed for at the very least 2 years, and clearly AMD have no intention to fix it.

This issue is still actively avoided by AMD and not being addressed. Pretty much everyone with RDNA1,RDNA2 and RDNA3 GPUs that's using a 240hz monitor + a second monitor is affected but AMD's dead silent because that makes for a small minority of people.

I have just started to have this problem with the 24.7 (possibly also 24.6) update. 24.5 was fine. The worst part is I got one of those Samsung Neo G9 monitors which specifically work with the 7900 XTX and switched to that card only to have this problem. All I can think to do for now is roll back and hope some future update fixes it. I am concerned this problem has been around for so long though, even if it wasn't affecting me. Now it is getting worse? And will it ever get better?

High bandwidth monitors, especially ones that are using DSC seem to be breaking the signal in some weird way. AMD will never address this because if you think about it they have 15% market share. Out of those 15% how many people actually have a high-end GPU that can run high-bandwidth high-res monitors? And out of those how many have those types of monitors? Reality is large majority of AMD GPU users are running a 6600xt 5700xt and similar gpus with at best a 144hz 1080p screen. It is a very sad situation because I have a 6950XT sitting in a box, gathering dust and I had to spend 1200EUR on a 4080 SUPER. But given the fact that people with RDNA1, 2 and 3 GPUs are experiencing this issue and it's not been fixed yet my guess is it will never get fixed.
