I have some questions about o.c.ing a 3770k first off I read that with stock heat sink under prime 95 the temps clime to 95 C before settling at around 86 C under the full load. I currently have mine under a stable o.c. of 4944 mghtz but my vcore sometimes peaks over 1.5 like 1.522. I'm on an ASUS Sabertooth z77 mobo, with a push pull on a triple fan rad, and a single fan on a single fan rad. my temps climb to 95 C then settle at the high 70s low 80s C under full load, with my vcore temp slowly climbing to 40-50 C. My main concerns were first off is it really bad to have the vcore go up over 1.5 because I have seen a lot of articles about ppl who have o.c.ed their 3770k to 5 ghtz, and I don't see how that is possible without putting your vcore over 1.5. my secound concern is the temps, i believe the temps are fine since they are around the same as with the stock cooler without o.c.ing at all. and lastly about the vcore temp, it seem s to be a bit scary to me, but at the moment I don't have very good air circulation throughout the case, and the vcore isn't water cooled, which I intend to remedy by getting more case fans.
