But after adjust the CPU ratio in BIOS and boot into the Windows, the ratio of this CPU does not change. What should I do?(12/19/2007) Answer: Actually, it is AMD® CPU driver's behavior. To perform overclocking please disable the "Cool 'n' Quiet" function in BIOS-> Advanced-> CPU Configuration-> Cool'n'Quiet. Please refer to the following picture.
