At same CPU speed, higher FSB/RAM better?

[KD28]

At a given CPU speed, would it be better to have higher FSB/RAM speeds? For example, say I wanna keep a 1:1 ratio which would be better?

450 FSB x multiplier 8 = 3600mhz
400 FSB x multiplier 9 = 3600mhz

or say I just wanted a baby OC and didnt want to stress my components:

400 FSB x mulitplier 7 = 2800mhz
350 FSB x mulitplier 8 = 2800mhz
310 FSB x mulitplier 9 = 2835mhz

I'm lead to believe the higher FSB may perform better but stress the system a little more? If it matters, I have a e6600, Buffalo Firestix, and a DS3.


Oh, and which, if either, would tend to need higher voltages and increase temps? I know (and I will) test these things out but its just nice having general knowledge and advice from more experienced folks before I do.


Thanks =)

I asked the same question here:

Well, a bit of a different question and another slightly different question, but anyways, check the driver heaven review I linked. In real world performance (not pointless sandra graphs) it doesn't look like upping clock speed or tightening timings does a whole lot for anything.

Review:
http://www.driverheaven.net/reviews/PC2-6400 7-way memory round-up/index.htm

They experiment with tighter timings at 800MHz or clocking higher to 1100 MHz. While bandwidth goes up (yippee, who cares) real world performance increases by a very small margin. 1s on super pi etc. Unless you are a benchmark fiend I would say don't bother.

So I've resolved to stick with running 668MHz ram. Woohoo!
