Question Random crashes after RAM change

[Janhongi]

Hi!
I got Asrock z390 phantom gaming montehrboard and now I'm getting random crashes after RAM change..

I had 4x 4gb g.skill 3200mhz rams and upgraded to 4x8gb g.skill 3600mhz rams.
Sometimes I can game 10hours without problems and sometimes I crash in a hour. Mem tests showing no problems. In BIOS event log says "memory size different" when crash happens. But I can't find info from internet with that error. Any ideas?

Welcome to the forums, newcomer!

What BIOS version are you currently on for your motherboard? What OS version are you on for Windows 10? Did you change the motherboard? From the way you've stated the thread, it's as if you did a motherboard/platform upgrade/change.
