I did the 2 pin mod using rear window defroster repair kit. I just pained a little bit on the socket and made sure it did not go over any of the other pin holes. When I did this, it opened up voltage choices in my bios up to 1.85v. This is on my IT7 board. What is nice about using the repair kit is you dont have to worry about breaking a pin off of the CPU, and it is easily removed with acetone.
