Regarding 1T and 2T

post #1 of 9
Thread Starter 
Questions, i have an asus mobo sabertooth 990fx. My questions is what should my timings be set to 1t or 2t or auto?
post #2 of 9
2T is more stable than 1T. 1T is a tiny bit faster than 2T, but not enough to matter in everyday tasks. Helps is memory benchmarks.

Set it to 2T.

With that CPU and the memory you have, you should be able to run it easily at 1T

Stick with what the manufacturer says.

Unless you run an APU, then by all means try to achieve 1T. The performance boost is rather notable.

I use 2T only if it provides an extra 166MHz or more, over the same memory @ 1T.

The difference between the two is essentially:
1T - Fastest setting (literally half the time as 2T), improves latency across the board, provides a good amount more bandwidth at any given frequency assuming that the other timings are the same.
2T - More stable with "pushing it" overclocks, is typically necessary when all memory DIMM slots are filled and/or with 8GB DIMMs, is slower, reduced bandwidth, and for "normal" overclocks is not necessarily needed for stability (ie lower than 2600 9-12-12 or so)

The difference between 1T and 2T with my Ripjaws Z DDR3-2133 9-11-10-28 16GB (4x4GB) kit in my RIVE, running completely stock speed and timings, with the 3930K @ 4.5GHz, was about 8-13 percent according to MaxxMEM, AIDA64, and a few others. Cut my wPrime time by about 5sec, and another 5 off SuperPI 32M.
It didn't require any adjustments besides simply switching from 2T to 1T.

I have not used 2T since, and I've had no issue running my memory at 2442 9-10-10-27 1T 24/7 for the past few weeks, or DDR3-2284 8-10-9-24 1T for a week and a half (did require 1.6875v for the VDIMM).

if it's is stable, then run 1T....especially if you're only running @1600MHz

I have amd 8350 running at 4.6ghz and memory is G.SKILL Ripjaws Series 16GB DDR3 1600mhz. Please let me know what should i set it to. All of my slots are filled with 4 sticks each, so should i set it to 2T?

I checked the bios, it was set to auto but it showed up value 2T. Should i set it to 2T or 1 T?

Set it to 1T, if it boots, leave it as 1T, if it doesn't boot or you get any BSOD's, get revert the setting back

Pretty much this. If it will run stable at 1T, then there's no reason NOT to run it with the faster of the two available Command Rates... However, if no amount of tweaking will get 1T stable, then run 2T and don't worry about it.

FWIW, I've generally found that, oddly enough, tighter secondary and tertiary timings tend to make 1T more stable, while looser secondary/tertiary timings make it less likely to "take".... Weird, yeah?
