If you buy a dual slot 1 board, maybe... The Celeries are 'not able' to dual process unless they are slightly altered - forget the exact thing, but have seen it around. The Abit bp6 automatically gets around that. Many slocket's do as well. If yours are able, you could plug it in and it would work, but since they are different processors, you'll get a performance hit. Best situation is to use as close as possible to identical chips as you can. The further apart, the more the hit.
