From my experience 500 with those timing would be faster. Try a program like Everest, it has a memory speed test. Not sure thoguh 1:1 and tighter timing may mean better performance. Try Everest see what kind of numbers it spits out.
tighter timings vs speed?
Hello fellas its been a while but im back with a question.
Ive got some 2 x 2 gskill ddr2 at 500 mhz. These are running at
5-5-5-15. Now i changed it to 400 mhz, and i could get the timings to
4-4-4-9, which i think is pretty damn good. What im wondering, and im not sure if theres a difinitive answer, is are smaller timings going to show better performance than 100 mhz,, or 200 because of ddr2?
Thanks

Oh also i am now running at a 1:1 ratio on cpu/ram which may also be good

Here is the same FSB (410) with the same multiplier, but with different RAM timings and speed because of ratio:
4-4-4 1:1

5-5-5 4:5

I gain about 10% at these settings
I've seen a few who've had better scores with lower latency vs. speed, but as a general rule, speed wins out on Intel based systems.

Here are two extremes
5-5-5 5:6

3-3-3 1:1

I must say though, this ram at 3-3-3 667Mhz is just as snappy as when i put my CPU up to 3.6-3.8Ghz. My CPU is only at 2.5Ghz, its much snappier then my CPU at 3.2Ghz with my ram at 5-5-5 1120Mhz. Which is really odd since my FSB CPU and ram are all slower?

That is very strange. Have you run SuperPi at both speeds?

Testing in Superpi isn't good idea, because it likes tighter timings and in games/other benchmarks higher clocks will be better. Anyway, the difference will be about 1-2% I guess and something like 1000 5-5-5-15 is in 100% sufficient

Overclocking CPU/GPU gives better effects
