I've got a system here that I'm helping someone set up - I didn't purchase it myself.
It's got a 2.4gig P4 in it, but I'm curious if it's a B or C. Currently running at 533 so I'm assuming B, but would like to know if there's a way to find out for sure.

If anybody's got an easy way, let me know. I suppose I could pull off the heat sink and see what the markings say, but would prefer something software if available.

you can download a program like wcpuid or cpu-z from the top of this forum and see what the multiplier x fsb is

if the mult is 18 x 133 then it's a B

if the mult is 12 x 200 then it's a C
