There must be a way in the P8P67 UEFI to manually set the max CPU voltage. Anyone know as it seems to be doing it automatically at the moment or is this part of the digital VRM?

EDIT: Found it, had to scroll down doh!

Have now got my i5-2500k running at 4.2ghz @ 1.275 in BIOS Coretemp shows 1.3461 not sure if that is correct... max temp 77C stock cooling.

I checked how hot it went with voltages set to auto @ 3.7 and it got to 67C

So far Prime stable for 11 minutes Small FFTs... I am quite pleased with this as I was aiming for about 4.3 with stock cooling so am about on the money.

EDIT: Prime was unstable after 16 minutes... so I just installed Speedfan and its telling me my vcore is only 1.18v but temps in Coretemp get up to 77C! My next purchase will be a decent cooler to push up the vcore and keep the temps down, but I just wanted to see what stock cooling was like. Is Coretemp accurate?

EDIT: Pushed the vcore up to 1.28 in the BIOS CPU-Z and Speedfan showing 1.192v temps about the same max 77C will see how long Prime lasts. As it stands seems I have plenty of scope to up the voltages as long as I get a better cooling solution which could knock 10-15 off my temps.

EDIT: Decided to back off and wait until I receive a new cooler, just trying the OC tuner which gives me 4ghz automatically will see if that is stable now.

EDIT: Gave up on the 4ghz OC tuner overclock because it wanted to give the chip 1.240v as according to CPU-Z and at the temps I was seeing I did not want to push it higher then that. At the low volts I was using and the high temps I was seeing a decent air cooler is a must.
