1t is better, but most DDR2 is not stable at 1t. You may be able to get it stable, but usually the timings need to be so loose there is a loss in performance.

If you can get stable at 1T use it, as there is a 5-10%+ performance increase availble using that setting. However as drald says you may have stability issues with it. I used it a while back with some Corsair GB DDR TwinX and the difference in performance was really noticable.

It's the command rate for RAM. It used to be for AMD ddr1 systems you would want 1T for running dual channel with 2 sticks.

Now it's very unstable, so just leave it at 2T for ddr2 and you'll be fine.

If you can run 1t then do it. With 2x1g you should be able to get 1t stable with no problems. When you go to 4 dimms then you don't have a choice but run 2t.

As far as performance loss 1tvs2t, I'm not sure. Some people say it's acctually a significant difference. But then again 2t gives you more stability so you should get away with higher clocks overall.

2T is when your RAM is running too fast, for your mem controller, so it'll need to 'STABLIZE' its drop down to 2timings, or 2T. which by benchmarks does make a diff but by you actuall eyes it wont

With ram running at 1T there IS a visual difference to in speed AND response times. I've seen it.

most DDR2 ram won't be able to run 1T... especially with more than 2 slots filled... the ones that can run 1T end up having to run closer to stock speeds (no overclocking)

For example my SLI-readies can run 4-4-4-15 1T @ 800MHz.... but get better performance from 5-5-5-15 2T @ 1000ish MHz

1T offers a nice bandwidth boost over 2T, but most sticks can't handle it and will benifit more from having their clock speeds pushed

I ran the crysis benchmark tool at medium res, medium settings to get an idea of how much difference there is between 1t and 2t.

Same exact same settings, clocks and timings at 5-5-5-15 with g-skill ddr2 800, only variable was 1t or 2t did 3 runs these are the averages:

1t Average fps: 27.7

2t Average fps: 27.685

I honeslty expected like a 5% hit at 2t. But given these results I'd say it's a very small difference especially since you might get away with higher clocks with 2t.
