Pc is from early october, made it myself
Problem: mostly fast reboots, rare blue screens
dump: https://easyupload.io/gycby0
Is the WHEA_UNCORRECTABLE_ERROR event 18
Those reboots mostly always happens right after system start, by opening a video or using the search in windows, or else after a couple hours during some low activity like browsing, youtube or league of legends.
I never crashed in bios.
Never crashed during heavy gaming load or OCCT. ( bu i suppose it was jsut "stable day")
Now, after those reboots the ryzen behavior.. change and i have the core number 6 stuck like this: (also voltage stuck over 1.4 and higher temps)
This is idle but core 6 IS ALWAYS over 4mhz.
For some reason, the pc is 100% stable with this, never crashed or rebooted.
After restart it go back to normal (all cores go in idle, 35-40 idle temp) and the reboot lottery start.
I'm 100% clueless.
I updated everything, updated the bios, did 2 cicles of memtest and all OCCT stuff for 1h, 0 errors.
Windows is fully updated, i do dism/sfc often and no errors.
Bios settings are stock default, only xmp 1 enabled for 3200. (but disabling or going 2 for 3000 change nothing)
Now, most days the pc is stable, had even 18 consecutive days of no reboot until few days ago, i use it 14h/day.
Pc is recent, fresh windows pro 10 recent iso, the extra stuff at start are just mouse program, mozilla maint, realtek audio and Nvidia display.
Do pc load with something wrong?
Is cpu defective/damaged? (but still can work well for 18 days?)
Maybe the mobo or something is sending wrong voltage? How do i check? I don't have more ryzen or recent mobo around.
