Current system:
Cpu AMD FX8350 on 6 cores (5&6 core disabled in BIOS) @4.3GHz
Ram Gskill Ripjaws 1600xmp 24GB (2+1 modules)
MB Sabertooth fx990 r2 asus
Psu CorsairRM750x
GPU ASUS R290 STRIX
Ssd Samsung evo 250 + 4 HDDs
Watercooling setup and working on CPU
temps CPU 35c GPU 55c (under load)
CPU 26c GPU 35c (idle)
History:
I started noticing problems 2-3 years ago. PC was freezing randomly even when idle. Lost a memory stick. The problem continued with random shutdowns. I found that the problem for the shutdowns was the PSU and I changed it with a new one. But the freezes continued. I finally found a clue, when I run Prime95 on all cores, PC freezes (all ok on screen but no input possible) almost instantly. Then I entered the BIOS of my MB and found that problem only goes away if i disable cores 5&6.Then I can run the program all day long without any problem. I am at a loss, what could be wrong? Is it a CPU problem or MB, due to that I had a spoiled module already?
How do I continue troubleshooting now? Can I check somehow my hardware further? Tried clear-CMOS, stock speeds on all components, underclocking all cores, different set of RAMs, Format, BIOS update, extra cooling etc... No solution. Unfortunately I don't have another compatible PC to interchange MB and CPU to see who is messing me up from the two! Any clues guys??
EDIT: Is the memory controller on FX included on every set of cores independently? My thought was bad memory controller, could it be?
