RAM timing 1T vs 2T

post #1 of 6
Thread Starter 
I read the sticky thread above but still couldn't understand exactly what this does. Could anybody explain?

I have Corsair Valueselect 667s in my system which I think are holding my E6600 back from stable OC past 3.2ghz, even when I put the RAM in unlinked mode from FSB. Would switching from 1T to 2T or 3T help this situation?

Thanks.

What about Command Rate?

Command Rate is sometimes referred to as DRC (DRAM command rate). This is the setting that selects the speed of your RAM signal controller. If it is set to 1T, then the controller will run in synchronization with your bus speed. Higher settings will result in slower overall RAM speed, which translates to less bandwith and yes (you guessed it) more headshots for you. Most decent RAM modules will run at 1T, but some have to be set to 2T. The moral of the story here is don’t buy value select RAM!
hahaaa............... I just read this from the FAQ. So now I know what 1T vs 2T is. Can anyone give me a general idea of what C2D @ 3.5ghz w/ 2T command rate will be like versus 3.2ghz w/ 1T command rate performance-wise?

i don't think on intels' that 1t or 2t matters much. all it is is command rates per cycle that your memory does. but 1t or 2t only matters really on AMD procs.

While I do not have any personal experience with the 680i chipset, it has been stated several times by multiple leading benchers that 680 performs exceptionally well at 1T with tighter timings (400-450 3-3-3) and that at 2T you do not begin to see matching performance until 550+ @ 4-4-4.

The reality of the situation though is that you have ram which can do neither those speeds nor those timings. As such, my move would be to stay with 1T because in my opinion, going from 3.2 to 3.5 isn't going to grant you a noticeable performance gain seeing as you are not bottlenecking your GPU (this would not be the case had you matched that 680 with a G80 which sees performance scaling up to 3.4) and your memory will not be able to scale with your CPU.

Aside from that your load temps at 3.2 are already at what I would call the ceiling for C2D (some would say 60, I like to stay comfortably under). Taking a hit from 2T and higher temps for 300MHz? You decide.

Yeah I agree. That's why I just ordered 2 sticks of Ballistix PC2-8000s and a Tuniq Tower last night. When I first started building my rig I promised myself I would be happy with OC'ing to 3.0ghz. I was at 3.2ghz and now I'm at 3.4ghz.

I would say OC'ing is analogous to gambling. You keep pouring time and money in, and you never know when to stop.

yep it is sad. i started back overclocking again last year in november and now the only original parts i have in my computer are my video card (which hopefully is going to be going away very soon) and my motherboard (which is staying for a long long time i <3 it). too much money
