Memory Frequency Higher than FSB of the cpu
« on: October 23, 2007, 07:11:51 AM »

Hey,

Just a quick question

Is there any problem with running memory at a higher frequency than the fsb of the cpu. So if you give it a ratio of 4:5 the memory runs a little faster. Will it do anything at all or do you just then just get a bottle neck sicne the cpu cant talk to it any faster than its own fsb speed? The memory is rated for a higher speed than the processor and it feels like im wasting it but I dont have the cooling to handle a higher fsb on the cpu at the moment

Well, historically memory speed > FSB has been done; famously, the old VIA KT133 chipset would run RAM at 133 and FSB at 100.  I think it supposedly provided a bit of a perk; probably because it coped with latency.  (memory that takes x clock ticks to be ready is faster when the clock ticks faster than the mobo)

If i recall correctly, Intel core2duo is supposed to be better if the fsb/ram are matching (synchronous) similar to AMD.  P4s benefit from asynchronous speeds where ram can be faster than fsb.
Doubt it would make a noticeable difference though

Benchmark it, change it, benchmark it, compare.

I haven't seen anything done along these lines in a while, but the research really isn't too hard.
