I have a couple of questions here. I've heard alot of talk about the memory controllers onchip in the 3500, 3800, and 4000. However what about the other 939s? I've seen 939 3000s on sale at newegg, and was wondering, if the mobos don't have onbd mem controllers, how (or if) they run on the 939 boards? The answer to my question would of course be that they also have memory controllers onboard or that they cpu's can't run on there, or that the cpu's acutally do have onchip mem controllers? [Winchester 939 vs Newcastle 754 (are the 754s onchip mem controllers as well?)] Help!
