Cco or Cbo stepping, what is this?

CK,

A stepping refers to minor revisions in a processor core as it goes along in it's product lifetime. For the P-3 1 gig you're looking at, there will be some information printed on the top edge of the plastic back plate which will probably start out something like this for a 1 gig P3 at 100 Mhz front side bus: 1000/256/100/1.8V

The very last bit on there, after the country of manufacture and everything will be a code, starting with an S. I'm looking at the backplate of a P3-700 and it says SL4C3. Jot down that "S Code" info and go to the Intel website and input it as a search. That should pop you up a list of processors, including the one you're interested in, with a bunch of data, including which stepping it is. If this is a recent or not-yet-made acquisition, odds are very good that it'll be a cC0 stepping one. The advantage is that this stepping tends to be a bit more overclockable than the previous steppings. But the cB0 wasn't bad either.

Hope that helps a bit.

If you're buying a retail boxed CPU, the S-Spec (hence the stepping) is the last 5 characters of the Product Code on the box.

Good Luck!

cC0 is the architecture for the 1133/133 effort. It shares its multiplier with the 850/100, which should be a pretty good overclocker.
