I have a 3930K on an Asus P9X79 PRO, under a Corsair H80, and it is 100% stable at 4.8Ghz. It get's pretty hot (high 80's to low 90's c) but that is in spec. I fold on it 24/7 in the winter when electricity is cheaper, and it is very stable and very fast. You do have to get the voltages into the 1.4v arena though. The CPU could probably do 5Ghz if I had better cooling. That CPU is just a BEAST!

The temps may be within specs but I can pretty much guarantee your chip will degrade a lot faster running 24/7 at those temps. JMHO

It will be trash long before it dies. I mean yeah, I may have reduced the life from 100 years to 25, but that's not an issue for me.

SrsBsns posted : I also just got a 3930k so this will be interesting to watch. I'm still learning about how to OC this system as its my first intel.

I wanted to add this last part because I hear these chips can degrade over time if pushed past 1.35v.

Intel has overclocking insurance where you pay a small fee. If you burn up a chip you get one free replacement.

Relkin posted : I did a 3930k build using a p9x79 deluxe motherboard and h100 currently running at 4.6ghz. Core temps run around 70-75 or a little more if the room gets too warm. I had it at 4.7ghz stable but it took a big bump in vcore to get it and was running warmer than I like(75+) so settled on 4.6. To get 4.7 it took 1.42 volts and only 1.37 for 4.6. As far as safe temps I've heard 80+ is ok but it's your chip so up to you how much you want risk killing it early. Personally I like to play it safe and stay close to 70. Also running 8 sticks of ram is going to be harder on the memory controller and may limit your overclock.

Krisnatharok posted : Do it in 100-200mhz steps. 400mhz may be fine for the first jump but you want stability, so go in small increments.

It's been a while since I OC'd, but if memory serves you nudge the multiplier until it is unstable in stress tests, then nudge the vcore up until it is stable. Rinse & repeat.

The system has already been pieced together and is running Windows 7 Pro. It runs very fast, but I want it to run faster. I want to bring the CPU from 3.2 Ghz up to 4.8 Ghz. I want to do this in steps so that I can monitor temperature at each step. 0.4 Ghz increments sound good. So I would start at stock 3.2 speed, run a program to max out CPU, measure temps, then increase to 3.6, max out CPU, measure temps, then repeat with 4.0, 4.4, and 4.8. Has anybody had any experience doing this with my motherboard and CPU combo? Any suggestions? Also, what temp should I not go over as I am stepping up the speed?
