ok, now some other stuff...

as soon as I enter CPU oc mode (i.e. anything above 3 GHz for 1700, no RAM oc) it fails OCCT CPU Large test after ~10 min (bluescreen, auto-restart etc.)

the weird thing is, say, I can run all kind of stress tests stable, like Realbench for 8 h, linpack for 1 h, cinebench, SuperPi32 etc. EXCEPT OCCT CPU Large - instant crash. Different frequencies, vcore, llc, soc, I think i tried everything even downgraded BIOS to 2.40 - same problem

disabling SMT seems to solve the problem... question is what's at fault here... board, software, cpu or something else

I would greatly appreciate if someone could run OCCT (v.4 5.0 latest) CPU Large test on Gaming K4 with an oc Ryzen and see if the crash can be replicated. Thank you.
