memtest86 11.3 is a standard part of my build routine, it passed that (4 passes is the standard that the free version allows you to do, an older free version allows a custom set of passes to be set but IIRC it wasn’t compatible with AMD9000 so I updated my memtest86 memory stick to that version). I didn’t bother checking the second module.
It crashed with the third module (plain Kingston non Fury, DDR4-3200, I had to reset the BIOS presumably because of the old XMP config, then the BIOS detected the new module and ran it at 3200MHz automatically. I then went straight into my current standard test for this problem (23H2, no updates, video driver, monitor set to power off within 1 minute, no sleep mode).
I’m now trying a janky PSU that the case came with because it’s the newest non-Corsair spare PSU I’ve got. Impressively quiet PSU, I’m surprised.
If this doesn’t do the trick, then logically I have to come back to the SSD because the Intel SSD seemingly working fine. I’m just trying to get my head around the apparent facts in this respect though:
SSD1: Samsung 980 with heatsink = problem
SSD2: Intel 660p no heatsink = seemingly no problem
SSD3: Samsung 990 PRO no heatsink = problem
Another build I’ve done recently which is extremely similar to this has a 990 PRO 2TB in, I didn’t have any issues with that build (though my paranoia is starting to creep in, suggesting “well maybe you didn’t test it enough….”). I normally use Samsung PRO SSDs with this board.
When I swapped boards, I purposefully did not update the BIOS because the BIOS update is a recent one that I only applied to this board and the previous PC I built a week or three ago with the 2TB SSD in.
One other note: I would say most of the time when Windows “crashes”, the monitor is off and Windows fails to respond to standard wake-up techniques like mouse movement or a keypress. Sometimes it BSODs, and usually that BSOD is CRITICAL_PROCESS_DIED.
