"For the Athlon it seems like the KT266A is still the most desirable chipset and although the nForce definitely has its own niche, VIA shouldn't be too worried about it cannibalizing their Athlon chipset sales; not yet at least. The next wave of Athlon chipsets will bring about DDR333 support however unless the Athlon gets a boost in FSB frequency, something that isn't on any AMD roadmaps we've seen, you shouldn't expect to gain any performance improvement from DDR333."
I've read similar comments a couple different places. It suggests to me that the buss for the CPU would stay at 266 while only the memory would be at 333. How else would I not see a performance boost?
I guess another possible interpretation is that without technically overclocking the chip it won't see a performance boost. That is buying a 133Mhz FSB chip wouldn't allow a 333 memory speed unless it is unlocked which I suppose voids the warrenty.
Someone, just confirm that "no, they don't run asyncronously" and I will be fine. I will forget trying to under stand statements like referenced above.
