I'm trying to OC my 2500K and would like to tinker with a few manual settings.

I've currently got my chip set to 4.6ghz via the auto OC settings available on my Z68 Extreme 4 Gen 3. The volts seem to fluctuate between 1.336 and 1.344 in cpu-z when under load, with temps between 57-65° between the cores. This is being cooled by a Noctua D14.

Now my aim is to reduce volts to reduce temps and be a bit greener, as i hear the auto options are just aggressive defaults for all chips.
So my question is that if i wanted to tweak the volts manually should i just drop the volts to a safe and stable amount or should I experiement with the offset setting? Also what is this offset setting and how do i determine the value it should be?

Regarding IBT i've downloaded v2.52 but what settings do people suggest using? (i have 8gb ram).
 
for IBT you need 2.52 and windows 7 SP1.

To find your offset, get coretemp or something that will show your VID, take note of its highest value under stress (usually around 1.38v). You now need to deduct the required voltage to match your cpuz vcore. So for example your cpuz vcore is showing 1.344v, and for example your VID is 1.384v your offset would be -0.040.

Then to get things lower simply decrease your offset, so -0.050 would give 1.334v etc...

You may also need to play with the LLC, phase control etc...
 
there will be, just have a search about, I'd be surprised if there aren't more than few guides for the gen3 with it being so popular
 
Cool, I think I need to search for a guide as I tried the offset mode and set it to the load difference between coretemp and CPU-Z and the pc failed to boot.
Even tried reducing the amount but it was instable in window. Haven't touched the LLC and other settings as I think I need to understand them more.

At least the auto oc mode works 100% fine tho
