SPCR

I just got hold of my new server and HTPC hardware. In the past I have used speedfan to control the fan's speeds. But these new babies (a C2D and 4850e) support speedstep or similar. I saw somewhere that there is some piece of software where you can define the speed (and voltage) for the different steps, but I have forgotten the name of it. help is much appreciated.

You are looking for RMClock

Thanks

Or Crystalcpuid.

RMclock does not work in Vista64, but crystalcpuid does.
