Command Rate 1T or 2T?

post #1 of 12
Thread Starter 
I have a set of G.Skill HZ 2gig dual channel ram, my timings are 3-4-4-8. the highest ive gotten my ram is 263mhz (just to load windows, never tested on prime, im actuly testing 260mhz on prime rite now), with a 11x multi and 1.6 vcore at like 2.9ghz on air cooling. I was wondering what command rate I should set it at? 1T or 2T
my rig?

For the best performance the 1T setting is better. The performance boost will be noticeable in games and scientific calculations, in the other areas it is not that important. Benchmarks can tell you otherwise, but the truth is for example in video/audio encoding there is no difference between 1T and 2T.
The 1T command rate has however the downside that the memory won't be able to reach the same OC freqs that it went with the 2T setting. If you are using the 1T now and switch to 2T you'll probably see a slight increase of your max OC, but only if you are limited by your mem and not by the CPU, HT or mobo.

There is very little difference in real-world apps when using 1T vs 2T... if you can get the CPU speed running higher with 2T then this will help you the most.

See link in my sig on this very subject ...

Get to as high as speeds as you can using 2T, then see if it can go 1T. If it can, great! If it can't, don't sweat it. There is barely any difference in most benches I have seen.

I wouldn't be if that is as far as you droop. You are running a bit high on the voltage but your temps are excellent.
