Question: I'm using the AMD® AM2 Athlon 64X2 5000+ Black Edition CPU. The ratio of this CPU is unlocked. I would like to overclock it by adjusting the ratio. 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?(2007/12/19) 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.
