It should, seeing as I'm running a P3-700 on the same MB. Plus, "OCing" the Celeron won't OC your system, as it'll be running at 100MHz FSB. FYI, I'm able to get this P3-700 up to 868 on a 124MHz FSB, and that's with my memory and probably my video card (Xpert 128) holding me back--if you're not running the system out of bounds, it all depends on how OCable your Celeron is.
