It offsets from the CPU's VID voltage...stock voltage. You just need to mess with it and see what you need. Start with my settings and adjust as needed. CPU-Z will let you kknow what cvore you are at in the OS.

I just noticed that your specs indicate a 2500K, were those settings for a 2500K or a 2600K

Can confirm this guy is absolutely correct

Also with Hyperthreading off on my i7930 i can get higher clocks so even more Gflops dunno what they do like but i have lots with HT off

I have almost no use at all for the extra speed, i'd probably be fine with stock speeds. But why have a computer if your not going to overclock it?

Doesn't matter, it was my 2500k, but all you need to do is adjust the vcore to your cpu. Though you may not be able to hit 5GHz unless you have a good chip.

I have close to no idea how good of a chip it is, but IMO 4.7Ghz is a pretty decent overclock. I just want to say I have a really fast chip! Who doesn't?

Okay, so right now i'm sitting at 5Ghz with + .1v vcore for a actualy vcore of 1.48V after running several runs of linx using all 8GB of ram i'm getting a max gflops of ~72 is this right? I feel like it should be more. But at stock 3.4ghz i was only getting 52 gflops.

can anybody explain these results?

So that run took ~15 seconds and was 70 Gflops

You don't have hyper threading disabled do you! lol, I get 114gflops at 4.8GHz. Disable hyper threading and report back
