memory timing question

[MDme]

what's better

a) RAM SPEED 250MHz (DDR500) at 2.5-2-2-10 (2T) or...

b) RAM SPEED 208MHz (DDR416) at 2-2-2-10 (1T) (using ram divider)

both systems run at 2.5 Ghz

250MHz, no question.

Run some benchmarks to get the difference between the two (like a game timedemo or something).

Not according to this Test

"The very top of the memory tests are the most revealing results here. Despite the fact that several memories reached DDR600, highest performance was at the fastest speed the memory could achieve with a 1T Command Rate. This varied from DDR546 to DDR590, and it was at those 1T memory speeds that the best memory performance was consistently achieved."
