sirkillalotic Posted April 16, 2020 Share Posted April 16, 2020 Hello, I have a fresh build using msi pro carbon 570x and the ryzen 3900x. 32gb 3600 ram. I converted my machine to an img. Got everything working but when I put a heavy load (loading up ark video game) I get this system thread exception and not just this machine but my other separately cpu pinned fresh install os gets this error as soon as this one does and vice versa. I'll even have the converted vm off and the fresh vm has the same problem.(yes both machines will get the error at the same exact time). I also have the cores isolated so that unraid can only use 2 separate cores. I am passing though a 1080ti using vbios. I'm stuck to what's wrong and spent hours upon hours googling and tinkering. I'm on unraid 6.8.3 Quote Link to comment
testdasi Posted April 16, 2020 Share Posted April 16, 2020 As a strating point, you need to attach diagnostics zip. Tools -> Diagnostics -> attach zip file. Quote Link to comment

First thing would be not overclocking the RAM it's a known issue with Ryzen, see here: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/?do=findComment&comment=819173 Quote Link to comment
sirkillalotic Posted April 16, 2020 Author Share Posted April 16, 2020 (edited) Thanks for the replies, will post diagnostics ASAP As for the overclocking. The ram I bought was rated 3600, the board recognized it was 2133, so I manually set it to 3600. By not doing this the graphics was taking a SEVERE hit in performance. adjusting it made it nearly bare metal. So you are saying my 4 slots of 3600 need to be set to 2667? or maybe I should just experiment with dropping down the ram little by little? The unraid OS isn't crashing, just the VM's. Also when running against Baremetal the system runs great on 3600. Edited April 16, 2020 by sirkillalotic Quote Link to comment
testdasi Posted April 16, 2020 Share Posted April 16, 2020 Manufacturer rated overclock is still an overclock. Running "great" by performance doesn't mean the same with stability (usually the opposite). Also RAM speed usually should not have severe impact on your graphics performance. Most games don't even use that much RAM to begin with. What games are you playing? Quote Link to comment
tjb_altf4 Posted April 16, 2020 Share Posted April 16, 2020 Drop to 3200 and see how you go, 3200 is what gen 3 ryzen is rated to run at out of the box and should maintain decent system speed. You are running either both memory banks or dual rank, so that might be taking a toll on stability with the speeds you are running. Running memtest overnight would be a good idea to see if any errors appear at both your current speed and at 3200. Quote Link to comment
sirkillalotic Posted April 16, 2020 Author Share Posted April 16, 2020 (edited) @testdasi Interesting, I didn't know that...I was getting 15300 with passmark using the 2133 ram for a 1080ti and 17600 using 3600 setting. So I'm just talking about the benchmark. I'll try the 3200 and see what happens Interesting how only the VM's crash (both) and Unraid stays up Edited April 16, 2020 by sirkillalotic Quote Link to comment
