One interesting point here is that, in previous generations of chips, the type of ram a board could accept was based almost exclusively on your chipset. In the transition period between SDRAM and DDR SDRAM, several co.'s released chipsets that could accept both. The K8 moves the northbridge on-die. That means the ram it will accept is based exclusively on the chip itself. AMD is committed to DDR SDRAM, so we probably won't see any RDRAM K8 chips. The initial launch will support pc2700 DDR. Sometime next summer, DDR-II will start appearing, and AMD has plans for a K8 that accepts DDR-II at that time. (DDR-II is faster and completely backward compatible AFAIK.) -Matt
