OK thanks. PowerColor, Sapphire, and Amazon RMA and technical support have been very helpful to me in the past.
Not ever had to get help from XFX.
Punching up for AMD personnel to see, as far as I've heard this is still a major fault with first-gen vega cards.
After nearly 2 years of pain, i just got the rx 5700xt. Not perfect but far less problems.
I really really tried to fix the card but the problem was so fundamental that it was nearly not possible, just with hard workarrounds (HBM @500Mhz min clock)
Hope the will fix it or learn from it!
Thanks again Paul for your Ideas and advice.
I'm bumping this as it looks like AMD Radeon black screen issues are gaining a bit of public traction after all: https://www.extremetech.com/extreme/306175-amd-is-investigating-black-screen-driver-issues-on-radeon...
It looks like there's (at least) a similar issue on Navi cards as well. And it might be a driver issue after all.
Overall, it might be a good idea to contact writers of these sorts of articles and point them to this thread and/or at least point out the same issue exists on Vega cards.
I had 2*GB V56 OC having black screen crashes, completely random. 3rd card is working for about a year, absolutely no problem. So I think issue covered in this thread is unrelated to all Navi card issues.
Only other issue I had is black screen when starting CS GO. It was most prominent with 19.10.1 drivers. Yesterday I moved to 20.2.1 and it seems that it is solved or almost gone (did not happen so far). Card is completely on stock.
My five cents on this situation.
Hello, I have the same gpu (Rx Vega 64 Liquid Cooled) with the same bios and I was having the same problems. Than I figured that the vega 64 could not hit the p7 state (1752mhz) with its current power settings. Than I started to adjusting it. I finally find a brillant settings for my Vega 64. I can use it with no problem and cooler than before. My driver is 20.4.2. I always using the latest driver and I have not encountered any problems since I adjusted these settings.
For those who cannot solve this issue on Vega 56/64 and Radeon VII the most stable solution by far is installing the Radeon Pro Enterprise Drivers.
Don't load any config file for Adrenalin Gaming UV/OC just configure it all again from scratch.
It behaves quite different on gaming, reaching even higher clocks, different temperatures, and memory levels stability. And is free of crashes, at least for me and for other various users who tested it.
Have you tried this yet?
I will take a look at this tomorrow to see if I still get Black Screening on the latest drivers.
I have 2 XFX Vega 64 Liquids and one PowerColor Red Dragon RX Vega 56 I can test immediately.
