|Sigh... once again this old arguement....|
Okay, The P4/Core cpu's use a quad pumped bus. That is why it equals 667 (166.6 x 4), NOT like the AMD DDR bus (2x) of the Athlon xp's
Yes, going to DDR 2 667 would give a slight increase in memory bandwidth.
This is especially true if you are not running in dual channel mode. But even if you were, dual channel mode MIGHT provide a 5-10% improvement in real world tests, not a 50% improvement.
CPU FSB 667Mhz = RAM speed 667Mhz, end of story.
