Hello,

I overclocked my sandy bridge (i5-2500k to 4.8 Ghz) with CPU voltage set to "auto" in BIOS. I can't put a fixed voltage in as it uses offsets or auto (MSI z77a-g41).

Below is my HWInfo during stress test. When test2 starts in prime95, my Vcore and clock speeds drop to 1.12 and 3300 mhz for 2 seconds and then goes back up to 1.312 and 4800 mhz for 4 seconds. This repeats for the rest of the test (been running it for over an hour now).
