Thanks for the info. I actually found it right before your reply. It's printed extra small on the back. I've encountered another problem, though.
Does the P3V4X not offer support for a Celeron 566? The CPU box says 1.5v and it appears the P3V4X only goes as low as 2.0 w/ auto-detect. Has anyone gotten a 566 celery running on a P3V4X?
