cDO vs. cBO

[daddyloy]

Could anybody please Tell me what is the difference between an Intel CPU w/ stepping cDO and cBO?
I now have Intel 1.G cpu w/ a cDO on an abit ST6 mobo with Leadtek GEforce2 TI and 256 kingston Ram. Is this setup good for overclocking How far can I go? What could be my bottleneck?:cool:

[Placid]

You can go to 1201.5mhz ;)
I Had the sh6, kind of a middle of the road overclocker.
Maybe 150fsb's if it likes your memory.

[deez]

is it a 1 gig cele or P3?

if its a P3 is it an E or EB? (E=100FSB EB=133FSB)

[Yodums]

There are only cD0 steppings for the P3 1000E and Celeron II.

EB has like 3 steppings I think.

The PIII 1GHz EB has cD0 steppings too. I have two of them in my VP-6.

cB0 stepping and cD0 stepping have to do with when the processor was made (somewhat) The cB0 means that it was one from the first factory setup... cD0 came along later... not sure what happens... probably a manufacturing process change or revision ;) From what I've heard the cD0 overclock better than other steppings (cB0, cC0, etc.) Hope this helps :D

[Xaeryan]

The cD0 stepping is based on a newer manufacturing process than the cB0 (and the cC0)... this doesn't mean it's phenomenally better, but generally newer steppings have better yields, meaning better overclocking for you.
I have a 1.0GHz cC0 stepping PIII EB that only does 155 FSB. Many people with the cD0 version (yes Yodums, it does exist) have gotten it to 1250 reliably.

yeah, you're right there on the head 1250 the best I could go. I tried 1300 but it froze can't complete 3D 2000.

Rainmaker' you make me feel better! thanks

It is a 1 G. PIII- e500 or something

Use Sisoft Sandra to determine the stepping and whether its an EB or E chip.

[daddyloy]

This is how Sandra listed it- P6C (Coppermine) Pentium IIIE 500-1.13G....
and I using the stock Fan I might upgrade to a more efficient colling system soon.
