No, but it worked OK - there was some power management going, just don't know how much. (The original UnNlited inf was installed with "update driver".) I haven't gotten yet to try a full installation. The main thing I want to check is if intelppm.sys EVER gets installed with this hardware. Anyway, for power management of the processor I use RMClock and/or CrystalCPUID which work beautifully (the former just doesn't recognize half multipliers). And software UNDERVOLTING kicks a$$. GL * Edit - I doubt Server2003 or XP power management bothers to change multipliers/voltage on the fly, so those utilities are essential. For Vista, I don't know, but from the Control Panel applet I've seen on another computer, it isn't clearly exposed what does it do. You can just edit the .inf to say intelppm.sys instead of processor.sys and it seems to work fine
