Bios tweaks in windows?

I know with my old KV8-Pro I was able to change voltages, etc. from Windows. Is there a way to tweak those settings from Windows with the DFI NF4 board? Right now I'm using Clockgen, which allows me to change my FSB, and A64 Tweaker which allows me to change timings. Is there a program that I can use to change voltages too?

Central Brain Identifier does I think. Link

Thanks a ton! These are great!
