Hi Dave B; Re: "You said that two channels would provide 4.2GBs of throughput. That's DDR-II, not DDR-I." Sounds like a little terminology confusion here. With DDR-X, the "X" refers to the technology type, not the number of x64 channels. A single channel of PC266 (which is DDR-I), provides 2.128GB/sec bandwidth. Two channels of PC266 provides 4.256GB/sec bandwidth. That is still DDR-I. DDR-II is a faster version of DDR-I. It is supposed to provide bandwidth per pin considerably higher than the 266MHz of DDR-I. They are talking about 600MHz, maybe considerably higher. (Sorry I don't remember the details, it is still too far in the future for me to worry about.) Two x64 channels of 600MHz DDR-II would provide 9.6GB/sec. -- Carl
