Which overclock performs better?

[morbid3ntity]

E8400
Mushkin Redline 2x2GB PC2-8000 5-5-5-12
Asus P5Q-E

Overclocked to 500x7.5=3.75Ghz with memory running 1:1 at 500mhz 5-5-5-12
Overclocked to 416x9=3.75Ghz with memory overclocked higher than 500mhz fsb with looser timings 5-5-5-15

Thanks!

In real-world applications you will see no appreciable difference. I'd go with the second one though, since by using a lower FSB you're putting less strain on the chipset.

I had a similar question a while ago and was told not much difference. Personally, I noticed that the higher FSB setting was actually better on my PC at the same CPU frequency.

Try it and see.
I found that running a x9 multi and x8 multi with cpu at the same speed gave no measurable performance difference in any games on my E8400 + X38, DDR2-1000.
So I now use x9 with lower FSB to reduce stress and heat on the motherboard and memory.

Yeah I ran the full gamut of Everest benchmarks using two combinations w/ my Q6700: 360 x 10 and 450 x 8. In both cases, the ram was set at 1080mhz with 5-5-5-15 timings. Benchmark results were literally like 4% higher with the higher fsb. But running something like super pi 1million didn't make a difference. Also I've never really seen any advantage to running 1:1 fsb:ram ratios either. So IMHO I'd go with the lower fsb and higher multi. In fact, I'm running 360 x 10 right now even though 400 x 9 and 450 x 8 both work for me.
