Overclock advice on GA P67 D3 B3 with a 2500k

Hey guys, so I finally got the build in working order but ran into a few problems regarding overclocking. I've read various OC guides and I'm just looking for a modest overclock of about 4.2-4.4. I've disabled the various power-saving features that intel uses and I'd like to adjust the vcore but the BIOS isn't showing that option once I enable LLC (as opposed to auto). All I see are: Dynamic Vcore (DVID) QPI/VTT Voltage and System Agent Voltage. I've updated the bios to the latest version and it's still not showing the vcore setting. Is there any other way to adjust the vcore with LLC enabled or should I leave it on auto and hope for the best?

You should be able to do 4.4GHz on stock volts. You can adjust the volts with dynamic vcore (it will try to save you some heat at idle but could be unstable) or disable LLC and run at constant volts.

Thanks for the quick reply, just had another quick question (major OC noob but I'm learning quick). I'm at 4.4ghz and used DVID to drop the voltage to 1.29, but I also still have the C3/C6 state support turned on to keep temps cool at idle. For the sake of the cpu's health, should I keep it running at constant voltage (turn off C3/C6 state) or let it turbo up to 4.4ghz under load?

Letting the CPU run at lower voltages when idle will probably marginally improve the CPU's lifetime, but the real advantage is lower heat output (and therefore lower noise) at idle. So yes, I recommend using C3/C6 if possible. Higher OCs sometimes rule out that possibility, but take advantage of it if you can.
