OP can check CPU+RAM stability by using any reliable stress test (ex.: Prime95 - blend).
Will do a proper stress test later today and will post the results.
Having the issue here with my Red Devil 5700XT , happens at least once a day during games. Green Screen and then PC restarts.
Prime95 Blend test just done for 3+ hrs with full load and no problems. XMP was off and RAM speeds were at the motherboard default of 2133hz. Will do a full 24hr test when I have the chance to do so but as far as what this test has shown me it might not be a CPU + RAM stability issue because the crashes usually happen within ten minutes of play a game.
I must stress for anyone reading this thread to remember my original post of the conditions my GPU is crashing. Others have come to this thread about their GPU crashing under normal day-to-day use. I must reiterate that my conditions of which my GPU is crashing is a very rare and very specific conditions and does not just happen from normal game play of 5hr+ or just in general use.
Clearly it's not a CPU+RAM issue if you had no rounding erros during 3h Blend run. There is no need for another 24h round.
Most likely the problem you have is GPU related, either the gpu unit is faulty at a hardware level or there is an incopatibility due to your multi-monitor setup.
"Destiny 2 I have suspicion with it not liking the AMD graphics software as Destiny sees it as an "overlay" even when not in overlay mode"
Destiny 2 is definetely not perfect from a technical standpoint but my personal experience with this game running on AMD system (Ryzen 3600/5700 XT) on 1440p 144hz single monitor is decent overall. I've played it at least for couple hundred hours on this system switching graphic settings very often (low preset for PvP; highest with DoF - high, Shadows - High, FoV maxed for everything else) + opening radeon overlay and metrics overlay and had no crashes into black/green screen at all.
I would suggest to disconnect your second monitor and to try reproducing green screen crashes with a single monitor setup. If you won't encounter the issue with a single screen then at least you can be sure that it's not an issue with your particular GPU unit and changing it to another 5700 XT likely will not help.
I fix the problem on my Sapphire RX 5700 xt nitro +.
1) Remove the current driver with DDU, remove it completely!
2) Install version 19.9.2-sep23
3) Disable hardware acceleration in google Chrome.
My problems were resolved after several searches in various forums.
The solution found at this point was this. Hope this helps.
I have already gone through the process of using their software to remove the driver and do a clean install. Though I didn't use the driver you suggested. I will give it a try today and get back to you. Recently it has only been crashing on the game "Cloudpunk" if you or anyone else has it and can test it out as well that would help.
What were the reasons and conditions for your crashes? This may help but I don't think the issues should be counted as being related unless we are both experiencing crashes for the same reason. As someone has suggested this already I will be giving this a try to see if it clears up my crashes. My card is not crashing from normal use and I also don't see how chrome's hardware acceleration will have a play in my issue when I have already stress tested my CPU+RAM to be stable for now. Thank you for the info.
