B stepping & C stepping



I've been hearing people talking about B stepping and C stepping on P4's. I know that C stepping is generally better but can't seem to find any one who sells a chip with C stepping. Are all P4's 2.53 ghz and above C stepping or are some both.

C stepping is the same as the C1 Core. It's so far only on the newer processors, but might eventually make it into the lower end P4's. Right now, it should be on the 2.50 and 2.60 (400Mhz), and the 2.66 and up (533Mhz)


There is the 1.8 C1 but so far has been hard to find on the market. The 1.8C1 stepping overclocks really well so people have been buying 1.8 dell's just to get the chip because they are most likely C1 chips! Good luck finding one.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
