Recently got a P5K-E and E6750 and just read through this thread over yesterday and today. Very useful information here for a new P5K-E owner so I'd just like to say thank you to everyone who has contributed their experiences here testing BIOS versions and whatnot.

One question I've been having that doesnt seem to have been answered is about core temp readings. I am getting different readings whether I check the BIOS, PC probe II or through the Core Temp program.

Idle temps:

BIOS - 13C
PC Probe II - 11C
Core Temp - 21C

I'm assuming Core Temp's reading is the more accurate one as it reads directly from the DTS but it still seems a bit low to me. I do have an aftermarket cooler, an old Thermalright XP-90 (AS5) with a vantec tornado spinning at about 2800RPMs and my current vcore is only 1.125 (1.1 in CPU-Z from vdrop). Anyone care to elaborate on why the readings are different and also why they seem low?

Some other info...

P5K-E rev 1.02
BIOS v1006
