Is it possible to have better temperatures with higher voltage on CPU when running at the same MHz?
I overclocked an 2500k on a Gygabyte z68a-d3 motherboard to 4.5 ghz but i couldn't stabilize it.
Now i droped it to 4.2 ghz and tried to lower down the Vcore as much as possible because this is what people recomend.
Strangely, i noticed that when i have the CPU VCore on 1.28V(the lowest it can get without blue screens) the CPU runs
at ~75 degrees when i stress test it with Prime95, but if i set it on 1.34V it runs at ~67 degrees. Is this normal?
