My motherboard takes both, *believe me* I checked. In fact, I found out the hard way by buying another 4gb of DDR2, and figuring out that the 4 available memory slots unused were not for DDR2 but for DDR. The manual says I can't use both DDR and DDR2 at the same time. So I can do a max of 2x1gb of DDR2 (my current setup), or 4x1gb of DDR, which I must do to get teh AJ lits to load in BFD. That's why I was inquiring whether DDR is an OK choice, or whether it's time yo upgrade to a new machine.
