Too bad you only have one Kingston stick. I'd be interested in a DC comparison between the Kingston at 5:4 fastest timings you can versus the PC4000 at 1:1, 3-4-4-8. You have only SS sticks so it would be a valid comparison.

I'm not familiar with single channel benches so I can't explain what you see there. But that Kingston PC2700 does 260, 1:1 at 2-3-2-5??? Looks like it's the one with BH-5 chips. But the memory marks are about the same with PC4000 at 3-4-4-8 so it's not surprising the 3DMark score is equal.
