Hopefully someone can offer some help with the weird issue I am experiencing.
I have been experiencing apparently random BSOD issues for a few weeks. After a day of experimenting i have a bizarre way of triggering the fault to occur.
Boot the system from cold, tell it to seep, wake it up. If you try using the PC it is guaranteed to BSOD / freeze / black screen within a few minutes. If you restart in to memtest, it will fail test 7 every time.
If you use the reset button / hold the power button to shut down and boot back in to memtest, the fault remains. if you hard power off by cutting the mains supply then power back on, the fault is gone until the PC sleeps again.
I have tried a few things
Different memory kits: no difference
XMP enabled / disabled: no difference
onboard graphics / 5080: no difference
UPS on power: no difference
reseat CPU: no difference
different SSD and a clean windows install: no difference
reset BIOS: no difference
update bios (i was having BSOD issues with the bios i was initially running (7E34v1A81), the 200s behaviour is the same on both 7E34v1A83 and 7E34v1A9)
The machine isn't overheating. during a load test I can get the CPU in to the high 70s, memory in to the 60s. Voltages look stable. It doesn't matter if i run tests immediately following a cold boot or once the machine has been powered on for an hour, the behaviour is the same.
The only thing that changes the behaviour is changing performance mode.
In 200S boost I can have the above behaviour every time. In normal / MSI performance mode I get occasional crashes / memory test failures but only 1 in 10 tests show either a memory fault or one CPU core as faulty (OCCT / memtest). I can't reliably produce a crash without using 200S but it has crashed in normal mode. I only know 200S exists following a bios flash to try and fix the BSOD issue I was already experiencing.
If I don't let the machine sleep it will run for 4+ hours without issue. Once it has resumed from sleep I know it will crash.
My Specs are
Intel 285k
360mm AIO
MSI Pro Z890P-WiFi
64Gb G.Skill 6400CL32 (i have tried Kingston and crucial memory too)
RTX 5080
Corsair RM1000x PSU
WD 850 black 4tb M.2 SSD
Every component is less than a month old.
I am not sure if this is a motherboard or a CPU fault but i have tried 3 different memory kits and the fault exists with both with the onboard graphics and with a 5080 installed.
It's not impossible my random crashes are completely unrelated to the sleep / 200S boost problem but it is a major coincidence if i have 2 unrelated faults with very similar symptoms.
Has anyone else experienced something similar? i am tearing my hair out trying to find what's wrong.
