Dale, Of course, upgrading Clawhammer's integrated PC1600/PC2100/PC2700 controller to an integrated PC2100/PC2700/PC3200 controller would be easier than increasing the FSB of Athlon from 333 MHz to 400 MHz. I think that's the upside of integrated memory controller. Instead of dealing with 3 interfaces: -Northbridge to memory -Northbridge to FSB bus -CPU to FSB bus there is only 1 interface - CPU to memory which needs to change. There is only one company involved, and no need to synchronize the schedule of AMD and chipset vendors. You may recall that time after time, AMD suffered because of delays of chipset vendors. With integrated memory controller, AMD is in charge of it's own destiny. We can look back and see how things went as far as memory / northbridge support: -Via was way late with KX133. AMD had to do with it's own IG chipset and only PC100 RAM. -Socket CPUs delayed because Via couldn't deliver. It took some time after socket A CPUs for KT133 ro stabilize -low end UMA chipsets delayed. -KT133 couldn't really make it over 110 MHz FSB, new spin KT133A had to be released (I don't recall the timeliness) -PC150, PC166 SDRAM could be purchased, but no support from any chipset maker. -DDR chipsets from everybody delayed. AMD beats all chipset vendors with 760. In a completely unusual star formation, that happens only once per generation, increased FSB to (133/266), new memory (DDR), fastest memory speeds (PC-2100) all synchronized, released at the same time. -PC-2700 could be bought, but the chipsets not here yet. -even if the chipsets were here (and working), the FSB is out of synch, so faster memory would not help much.
