Memory speed and timings

I can run my memory (so it says) at 400 4-4-4-12 or 500 5-5-5-15. I run at the 400.
What is the difference, good or bad, for running 500.
Slower timings, but higher speed any advantages

You always want as tight of timings as possible, so lower speed, tighter timings is always better.

You won't notice as much of a difference if you switch the timings as compared to if you switch the speed. Run them at 500MHz.

Application determines which will serve you better. What are you using it for, mostly?

No. It's the other way around. Speed matters way more than timings.

The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP

Speaking of RAM speed, how do I overclock RAM? Or does the BIOS scale it with CPU overclocking?

Through FSB overclocking.

Okay, thanks.

Not always. Again, it depends on the scenario, and what degree of comparison you're making.

And the chips used, for that matter.

Download Sisoft Sandra Lite. Compare memory bandwidth and latency for your 400 mhz and 500mhz settings. Then make your decision. Personally I go with lower frequency, tighter timings, and 1T command rate instead of 2T. Tom's hardware showed that at least on my mobo (P5n32-e sli+) that tighter timings in 1T outperformed in both bandwidth and latency, and I verified this with lavasys and sisoft on my system. Yours may be different so try it. Also running 1T CR can be difficult for some brands of ram.

woops forgot to give u the link

o and im using 1000mhz g.skill at 800mhz 4-4-4-8 trc 20 cr 1T instead of 1000mhz 5-5-5-15 cr 2T as spec'ed by the ram. Overclocking the ram to 1100ish, well this mobo hates clocks above 1000 for some reason, and ive fought with it forever, so to be honest I haven't been able to compare high frequency overclocked ram, vs normal frequency tightened, but i have compared extremely tight timings vs default spec for this ram, and the 1T rate is better.
