Ive been overclocking my water cooled I7 3930K for the last couple of days and i am seeing some weird situations going on that did not happen to me with my previous board the Rampage II extreme.
I have it to overclock to 4.8 and it post and goes into Windows just fine.
The problem is when i run benchmarking or stability programs (Prime95 or Aida64).
Cpuid sees the CPU voltage at 1.424 at idle and the core speed at 4800 just like it should be, but when i run the applications the voltage drops to 1.392, 1.400. 1.408 and for a while all seems fine and no errors, but the the core speed drops to 3200 (Procesor default). After stopping any of the programs it goes back up to 4800.
I am getting no freezes and no BSOD.
Temps at 100% burn are below 78.
What does this mean?, is it that the overclocking is failing and instead of crashing like my previous board it just reverts to the default speed?
How about the speed?, why does it change?, do I perhaps have and option in bios for energy saving and that's why it shifts?
Also the ram comes with couple of cool fans but i cant installed them since they don't fit with the Gtx680 in place does it matter if I install the video card in another PCIE? or does it always have to be the highest one?
Any help would be appreciated.
All the best
