I curretnly have 512mb of pc2100 DDR RAM. I want to upgrade to 3200, because I believe that is the best my board will upgrade (I have a Asus P4P800, it only supports up to 3200, right?), but I can't buy a whole gig of pc3200 with my $ right now. If I were to throw in the 3200 with the 2100, what effect would it have? What speed would it run at in my comp, I mean will it seem as if it is all 2100, 3200, or somewhere in between?
