Hi Guys,
With my P5b deluxe I have the option of 1:1, 4:5, 2:3 and some other ones! for setting the ratio of FSB
RAM.
I am currently running an E6300 @ 3.2 by using a 460MHz FSB. I am running my RAM at DDR2-920 (1:1).
I have the option (at this FSB) to run memory at DDR2-920 (1:1), DDR2-1150 (4:5) and DDR2-1380 (2:3).
Can anyone explain to me the benefit of selecting the higher (async) dividers ? If I select 4:5 and run my RAM at DDR2-1150 how can the increased bandwidth benefit me if the FSB is still running at 460 ? Surely the RAM can only communicate at the same speed as the FSB, so is there any real world benefit of running greater than 1:1 ?

Time to do some everest/sandra memory benchmarks to see how I gain by changing to the 4:5 divider.
