Just a month ago, I decided to buy a new rig. I bought AMD Phenom X4 9650 with 2.3 GHz, Biostar TA790GX XE, DDR2 Kingston 2GB PC 6400, and a HDD WDC with 640GB capacity. I installed Windows XP Professional with Service Pack 2 and it’s ran smoothly. Then, I installed AMD Over Drive and Everest 5.0, just want to make sure I had no problem with temperature. I saw the processor clock at 2300.x MHz at that moment. I saw it at idle and do nothing. Just a week after that, I decided to install Vista, with service pack 1. So, I installed it. Run faster, smooth, and no problem. But, I just got shocked to see my Phenom clock at 1150 Mhz, cut by half.

Well, AMD Cool’n'Quiet™ tehcnology can not be enabled in Windows XP or below, just try it. I’m glad now I can see the AMD Cool’n'Quiet™ tehcnology runs in my desktop, make my home more light and energy-saving. This problem probably XP doesn’t support this feature, you have to change the power scheme in XP to activate it. Open the Power Options from Control Panel and choose ‘Minimal Power Management’ and click OK. If this still not working, just try to update your processor driver and try to look at the BIOS. Hope this information helpful.
