What scenario results in the higher performance?

[MISMCSA]

I can run my 4gb of gskill at 1400MHz, with 7T timings, or at 1670MHz with 9T timings.

From the information of read, it seems the 1400 with 7T would provide the better performance.

ne1?

Thanks

Why not run your applications and see for yourself if you already have the hardware.

get a memory bandwidth benchmark program
benchmark both scenarios
use your eyes and brain to determine which number is faster
every system is different, this will determine which settings are better for your system.

I have some 1333 ram that I basically did this scenario on, and the higher frequency gave better speeds. The timings didn't seem to change too much.

I would test applications you use more than a synthetic benchmark.

It may be my imagination, but 1400 CL7 feels a bit snappier than 1666 CL9. I swear windows loads faster @ 1400 CL7.
