My Gigabyte 7N400 Pro2 won't let change cpu voltage??

[mato7742]

once i'm in the bios, i can go to voltage and it will let me increase my cpu corev with only three options, however, i need to decrease the core voltage not increase it. everyone says they set their core voltage to like 1.60 or 1.75 or even lower, but i'm really confused as to how i can lower my voltage if the options aren't available? sorry i know it's a n00b question, but it would really help out since my cpu is currently at 57C (axp 2000+ palomino) thanks for the posts.

Your Palomino-core 2000+ is designed for a higher voltage than the later Thoroughbred-A, Thoroughbred-B or Thornton versions of the 2000+. It also produces more heat due than its younger brothers do. I don't think 57C is an indication of trouble... heck, I had an Asus board that would purposely run the CPU fan as slowly as possible unless the CPU temperature managed to reach 60C.

Realize also that mobos estimate the CPU temperature by an external thermistor, and they're not calibrated the same, so a reading that seems high on one board may be completely normal on another. Case in point: Abit first-generation nForce boards, which routinely read near 70C, while Asus' first-gen nForce boards routinely read about 45C. Quite a range of estimates goin' on out there, eh?

If you do want to lower your CPU temperatures anyway, you might consider either getting an upper-end aftermarket heatsink like a Thermalright SLK-800, or grab a newer processor with a cooler-running core. The Thornton-core 2400+ looks like it puts out about 10W less than your 2000+ Palomino, for example.
