Even higher latency RAM? I'm not sure about that.
Most current DDR2 memory modules run at 667Mhz with the same 533 settings, which most likely indicates that DDR2-667 will manage to operate with lower latencies than DDR2-533... (same timings, but lower latencies because clock period is smaller)
In any case, DDR2-667 is probably the breaking point for DDR2. It will make DDR2 show more of its potential if compared to DDR400; it's still a somewhat tough match, though. I'm thinking only once DDR2-800 matures will we truly ditch DDR400. I'd expect DDR2-800 with better-than-standard timings to outperform DDR400 in every possible way, and I wouldn't be too surprised if that were to happen in the next 6-9 months or so. Remember, DDR2-800 will be available as early as november 2004, and will certainly fit in the 2004 timeframe in very small amounts. And I doubt mobo makers wouldn't jump on the opportunity of supporting newer memory types, if i925XE were to support them, even for the enthusiast market, for the next 6-9 months. (that would also be good for bragging rights, if DDR2-800 manages to finally put a good light on the LGA775 platform as a whole!)
I do still have to agree, however, that this story has more bandwidth than common sense and more latency than necessary, and that's why DDR2's technology needs to catch up. It can only possibly bring benefits when it is fully developed and mature; DDR2-400 is a joke and DDR2-533 is not justified. Catching up is still possible, though.<P ID="edit"><FONT SIZE=-1><EM>Edited by Mephistopheles on 10/07/04 00:37 AM.</EM></FONT></P>
