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
