Hi group, I'm planning to build a new system, and this time, I'm thinking to use Core2 Duo. (Please don't start the CPU debate. I have a specific reason to use...

I only have one question - why undervolting?...

All Core2 Duo CPUs will run reliably at 1.05V at 6x clock. This is the EIST voltage/clock setting. Most chips can improve on this. Most ASUS, Abit and Gigabyte...

What I did was use the least expensive 45 nm Core 2 Duo I could get my hands on. Using these and under voltaging I'm almost tempted to replace the heat sink to...

There is another reason for reducing the voltage; but it is not usually a user determined function. If you are trying to switch a transistor from "on" to "off"...
