The Phenom chips have frequency scaling properties. The only reason to use this feature is to manage temperatures, if the frequency is lower the processor will consume less power and therefore run cooler. My computer with Thermaltake water cooling would run at 28C – 32C with the frequency scaling option enabled in the BIOS (AMD Cool’n Quiet). I currently have the BIOS configured with this feature off. The FSB is scaled to 215 with the multiplyer at 11.5. The processor voltage range is 1.15 – 1.25 and I have gold series OCZ 1066 DDR2 ram. The voltage for these chips are 2.1, and the timing is 5-6-6-18. Enable 2T and ganged mode. I cannot get the chips to operate at 1066, the computer wont post. No worries ram speed is not a major player in the speed of application launching. The FSB play a greater role. Currently the RAM is operating at 900 Mhz, and the processor is operating at 2.54 Ghz. The temperature of the computer is consistently 30C – 32C even under load.
