So the BIOS-update seems to have done the trick! All stable now, PBO and auto-oc on. The system could not handle MSI-Game mode settings for the CPU which have the CPU blasting at 4,2ghz constantly.

Memtest86 passed with flying colours, no errors, all 4 test completed at 6,5hours. I will search for bios upgrade next. Thanks for all the help sp far.

hi! I have just put together a new ryzen build and have run into some memory problems. hardware is tomahawk max ryzen 3600 g.skill trident z neo 3600 16-18-18-18-39 2x16gb asus dual EVO 2070 super Cooler master v750 psu For oc i have enabled pbo and auto oc in ryzen master. For the gpu i have 1000mhz memory oc and 60mhz core clock. Xmp enabled and memory rubbing at 3600mhz eithbstock timinga. All tested and stable in superposition, cpu-z, user benchmark. But then I got down to gaming and had unexpected crashes in rdr2. Tried aida64, system reboots on fpu test. then i turned xmp off and system works, but memory at 2166mhz. so my question is: any fixes for this so that i can run memory at 3600mhz or should I return the sticks and replace then with some better ones?
