So, I had absolutely zero stability issues with my GTX 1080 Ti and RTX 2080 on this exact system so I know that my hardware is good. I have put it through the paces of memtest86+, HCI memtest, Prime95 blend for 24 hours, realbench for 12 hours etc... and have had zero errors with my hardware other than with this GPU until I retweaked my system and am confident that the only issue I am having that is out of the ordinary is Forza Horizon 4 can't go 4k over HDMI but every other game can. Other than that I am rock solid. I have a 2018 Thermaltake Toughpower Grand RGB 1200W 80 Plus Platinum TPG-1200F1FAP (note: this is not the iRGB plus model nore is it the newer ARGB model) and it has given me zero problems so far. My unit was reviewed favorably across the board so I really don't think it would be my PSU. I do prefer Corsair for PSUs but I got this current PSU for free and decided to use it as all the reviews were really good. I had a 110% stable core system that had no issues running two nVidia cards fine but it seems that these 6800 XT cards are a bit more finnicky, stress the system more overall, and have smaller voltage fluctuation tollerances but like I said before after tweaking things I can game all day every day without incident as long as my VRAM is not overclocked though with raising the SoC (A) to 60 maybe I can get away with it now. When I first got this card I read so many threads of people (specifially with the MSI Gaming X Trio going through mutliple power supplies trying to fix their black screen issues and not a single person benefitted from switching out PSUs. Most people said don't waste your time switching out your PSU as these cards just have problems and AMD is going to have address them with driver and VBIOS updates which they have already said they are working on. I am just happy I was able to understand my system well enough to be able to tweak a few voltages here and there and I went from having black screens every time I tried to play a game to zero black screens other than forza @ 4k on the tv, haha. I just play it at 1440p on my tv and it looks amazing so I don't care. I am now trying to figure out a better cooling solution to get that hot air away from the GPU as fast as possible to deal with the high junction temps. I think I might frankenstein it and take the top shroud and fans completely off and add my own case fans to it that can cover a lot more area and push way more CFM at significantly lower noise levels. It is just so crazy how the junction temp is +30C over the edge temp. Anyways, thanks for the discussion.
