I've built 2 PCs with Crosshair 6 and both of them have some troubles.
1st computer - my own. So I have 3800CL16 stable with my Ryzen 3600x but sometimes I boot the PC and all memory tests are failing and the reboot solves the issue. This happens probably 1/50 times but still bothers me as it is the only case of instability. Would appreciate any advice on this one or some ways to debug this.
2nd computer was built for my friend. My friend isn't very good in computers and any unstable behaviour of it causes some panic. There's R5 1600AF and Patriot Memory(PVS416G400C9K) that is on Stock settings. This system failed working on stock, the reason: Sometimes the screen goes black and the CPU fan as if stops for a moment and starts again and this cycle loops. The Q-code displayed at that very moment is 8. Not 08 or 80. Just 8. This happens really rare, perhaps once a week but still this bothers a lot as it can crash any moment.
Sometimes the system doesn't wake up from sleep. AA Q-code is displayed as if everything is fine.
What we tried here:
I supposed that the issue is the plastic backplate of Hyper 212 Evo but this issue happened later on Stock AM4 cooler. Tried setting manual voltages for both RAM and CPU - issue happens again.
We have now changed the CPU to R5 1400 to test if there's some compatibility with AF CPU as it came out later than the latest CH6 bios, we haven't confirmed random black-screen-shutdown yet as we replaced it only yesterday but problems with not waking up still there. Also, there's a cold start for some reason.
P.S. I also never trusted to Patriot and I think the issue can be with the RAM despite it passing the tests successfully.
Let me know if there's anything I missed.
Any help will be very appreciated. Thank you.
