DDR2-1000 vs DDR2-800?

[Gerr]

Which should I run my G.Skill PC2-8000 2x2GB on my high performance gaming rig?


DDR2-800 with 4-4-4-12 timings at 1:1 ratio

or

DDR2-1000 with 5-5-5-15 timings at a 5:4 ratio

Doesn't really matter. The lower timings and 1:1 ratio are canceled out by the speed boost.

I'll honestly be surprised if the difference is more than 1 FPS.

Edit: Assuming there's any noticeable difference, which I would tend to doubt, you can always just try both and see what you find.

Granted, the difference won't be much, but that's the faster config.

theoretically DDR2 1000 speeds of 500mhz on the ram is faster, but in real world usage they're =

I have tested 800 Cas4 vs 1000 CAS5 with the CPU at stock. Most benches and apps I tested averaged about a 2% increase with a few memory intensive tasks getting as much as 5% using the 4:5. So, if your system will do it, I'd suggest the 4:5 @ 1000.

Did you run any in-game tests? I'd be interested to know what you found if so.

I ran 1 or 2 game demo benches. It's been a while and I don't have the results handy. In general, memory timings or running the memory faster than the CPU has VERY minimal effect on game performance or FPS. CPU cycles are king for gaming. Read around and find any memory review where they use games as memory benchmarks and you'll see it.

Yeah that was my general understanding. Cool.
