On my notebook, which has an old 2.2 GHz athlon65 uniicore (3700+), cpuinfo shows cpu MHz as 798.103
Does that mean that as I am typing this message, the cpu is running at only 790MHz?? How an I speed it up?
All amd processors are either locked (Multiplier set) or unlocked (Black Editions , unlocked multiplier) Which means the multiplier can be raised to adjust the cpu speed. I think you are thinking the cores themselves are cut and in some mobos you can unlock some cores. Amd Phenom x2 555 is a Phenom x4 555 with two cores disabled for marketing reasons.

It's a roll of the dice to see if one of these can be unlocked to show 4 cores. Some do and some don't
In reality when the price of these units are so low you could have got your self a real quad for just over 100 bucks
Good luck Michael
