DDR ram & thrashing L1/L2 cache

[Velocet]

Anyone played with boards that support DDR ram @ 266Mhz with Gaussian98 or
other computational software that thrashes the cache?

Im finding that the increased bus speeds on any of the boards and CPUs
I've been testing with g98 is the biggest speedup over any other factor.
(cache size on board, cache speed, etc).

I am wondering if anyone has comparisons for the same CPUs with the same
amount of ram on DDR and non DDR boards+memory for jobs that thrash cache.

Thanks.
