In addition, from everything else I've heard the Socket 939 cpu's have the controller built right into the chip and such systems can handle 4x512mb with no drecrease in performace. As I've been acting under this assumption, please correct me if I'm wrong.
Some steppings of athlon 64 in conjunction with some motherboards cannot run the memory at its rated speed. Examples would be having to scale back the command rate from 1T to 2T and clocking the memory down to 333mhz (from 400). For the most part this has been resolved on newer chipsets and steppings of A64s, but it still rears its ugly head occasionally with just the right (or wrong depending on how you look at it) setup.
