your ram does have very high cl 18
I have 14,15,16 on my miners.
I use 3000 or 3200
if you crash 💥 when you open ryzen
something is set wrong in the bios.
Do you think a Ram change to CL16 or CL14 is needed?
I don’t know msi mobos.
had bad luck them and don’t use them any more.
so i don’t know how to set the bios.
if you botch bios settings you run low.
you have something wrong besides the ram cause you cant get ryzen to run.
I don't know MSI either but RandomX isn't dependant on DRAM speed so it's a waste of time to tweak it.
CPU OC will help but Ryzens are notorious for little OC potential.
You might have to tweak the number of threads and affinity to get best performance.
You might also get better speed if you run as administrator, but I hesitate to recommend it for security reasons.
