I've set up my RAM:
Setting-up-G-Skill-F4-3200C14D-16GTZRXAs I was running AIDA64 System Stability test with my settings for over 10 hours without issues at 3066MHz I thought that I have solved all issues and a BIOS update would make 3200 MHz accessible.
But then I started getting problems with bootability:
Bootability-with-G-Skill-F4-3200C14D-16GTZRX-(BUG)Yesterday I've tried to OC the CPU a bit. I was able to stably run it at 3700 even 3800 MHz for hours (AIDA64 stability/stress test). But then suddenly my PC started rebooting without having made any changes in BIOS. I removed CPU OC settings but it did not help. I realized that now I have stability problems with running memory again. My PC freezes or reboots, sometimes in BIOS sometimes in Windows login screen, sometimes I am able to run AIDA64 stability test for a few minutes before it happens. These problems happen with the same settings that worked before (enabled me to run stably for tens of hours) at all frequencies above 2133MHz!
=> With the same settings at the same frequencies it sometimes does not even boot up, sometimes when it does it freezes and sometimes it works for tens of hours under stress testing. Thus my hardware behaves inconsistently!
What do you think is most likely the culprit - what should I RMA - the motherboard, the CPU (IMC) or the RAM?
