Petz, Time to market is I think the best argument of not dropping the Clawhammer. I don't know if including 2 DDR channels would from beginning would have delayed it. For the same reason that CAS 2 usually won't work with 2 DIMM's instead of 1. Imagine with 4, 6 or 8 DIMM's installed. I think you are talking about a different problem, which is number of devices on one memory channel. If you add more, the timing becomes more difficult. But dual channel actually solves the problem. For example, if you want 4 DIMMs, you could have 2 DIMMs per memory channel, instead of 4 on 1 channel. 2 DIMMs per channel are easier to implement, and can support more aggressive timing. Finally, with PC3200 already available, I have no doubt that Via and SiS will support PC3200 for Clawhammer before 2003. There is nothing Via or Sis can do. Hammer will support PC-2100 and 2700 natively, with it's on-die controller. If Via or Sis were to create an off-chip controller, it will not perform better. 2.7 GB/s with low latency will outperform 3.2 GB/s with high latency. The PC-3200 may be too flaky to support, and AMD will just have another spin which will support DDR-II. Joe
