Importance of 1:1 FSB : DRAM

if a CPU is running at 356x9 (3.2ghz) with a 4:5 ratio so the memory is at 949mhz better off than a cpu running at 400x8 (3.2ghz) with the ram running 1:1 for a total speed of 800mhz?

400x8 is faster than 356x9 due to the increased FSB bandwidth.

so a lower multiplier with a higher FSB is always better? this will also help keep the ram speed up aswell?

and just a quick side question, do ram timings affect tempreture or just the stability? I thought i was just voltage that affected temps and the timings affected stability if they were set to low. but my friend wasnt sure and i have no one else to ask XD

Just try and get your CPU and mem running as fast as possible, Quad cores can benafit from greater bandwidth but its outright CPU speed that matters, there is little recordable benafit from running mem 1:1, just get it high as you can keeping it stable. Memory timings made a diffference with older (socket A) system but not any more, loosen you mem timings if it allows a higher clock speed.
