Good 24/7 OC for 3930K?

post #1 of 6
Thread Starter 
I'm just curious what you guys think would be a good goal to look at. Not looking to break any records obviously, but I have an H100, an open window with cold New England air and two AP31s at full blast pulling. Currently at 4Ghz via the boards OC Genie feature but I know she can do better manually. What should I look for? Stock voltage? Overvolted?

I think its safe to say for prolonged life of the CPU, stay under 75-80c and 1.4-ish volts. Also, unless you blast the AC in the summer you will find that you may not be able to maintain the same temps and/or overclock then. All chips are a little different, and it depends on how you test for your overclock.

Start at 1.28v-1.3v and 4.0ghz and move up the multiplier until you experience instability with 100% load preferably using prime95. The amount of time is up to you, I say 8-12 hours at a absolute minimum for business use workstations. If you just game you may find out you don't need that much prime testing. I think 4.5-4.6Ghz would be nice for your setup.

It all depends on how much time you spend on it, but it doesn't take much time to find a chip's sweet spot.

Check out the tutorial in the Intel section if you already haven't.

Nice rig. thumb.gif

You are an folding fanatic - so pay attention that higher OC turns your rig in heater, with this CPU (after couple of hours your room will be a few degrees warmer) .Two fans blowing non-stop around the 60 degrees warm air. IMO for folding i will recommend 4.2/4.3 GHz (the best performance /heating ratio). At 4.8/4,9 GHz you will need A/C on in winter time biggrin.gif

Another one -> if you are folding with GPU and CPU in the same time - use those recommended tests with IBT/Prime95 but in those tests missing heat from GPU (they do not load GPU while testing), and PSU is not maximum loaded . IMO if you fold two days with no problems you don't need those tests biggrin.gif

Thanks to both of you, I don't GPU fold because of the 600 series issue (as soon as it's fixed you bet I will). I'll let you guys know how it goes biggrin.gif

4.5GHz is a very reasonable OC for a 3930k under a h100 cooler.

Probably will need atleast 1.3v for that speed.
