I have an i7 2600k and a p8h61 (NOT -M) motherboard. I was wondering if i would be able to overclock it (seeing as the turbo is 3.56ghz (you may say 3.8ghz but that's single core)) I just want to be able to get 4ghz out of it because I know i could get it to that with stock cooling.
I don't know if that motherboard can overclock or only modest overclocks, if the power saving features are greyed out then you won't really be able to do much.
You can try oc'ing on turboboost. Keep the multiplier at stock  run your TB frequencies at  in all modes(1core,2core,3core,4core), keep vcore auto and start up. Run CPUID and Prime95, if your vcore is to high use the voltage offset if the board supports it, at 4ghz you want a sub 1.3v vcore.
If the motherboard doesn't have any VRM coolers or any kind of power control design then you will likely toast the motherboard.
