Trying to Tighten Memory Timings

post #1 of 5
Thread Starter 
Okay, so I got what I need to know about CL, tRAS, Trc, etc.

I'm trying to tighten the memory timings as far as the BIOS Can reach (4-5-5-15-12-1T)

And I'd like to keep the Memory Mhz @ 1333 - But could settle for something like 1.2Ghz Or Higher.

The Stock timings are:

9-9-9-24-33-1T (On G-skill Ripjaws DDR3 1600)

what kind of voltage increase are we talking here? 1.6V's?

Bumping should be done once every 24 hours only. Be patient and someone will respond

CL-tRCD-tRP-tRAS-tRC-Command rate are to i.e. 9-9-9-24-33-2T
The 3 9's or whatever are the values you want to decrease first, do it as so:
8-8-8 (7-9-7 if tRCD of 8 unstable)
7-8-7 (or 6-9-6 or 6-9-7...) etc.

Then lower the tRAS, ideally the value of tCL + tRCD + tRP; 9 + 9 +9 = 27. Note that 24 can sometimes perform better though.
tRC should be ideally the value of tRP + tRAS; i.e. 9 + 24 = 33. Sometimes a different value may be slightly faster. i.e. 6-8-6-20-24 is faster for me than 6-8-6-20-26.

2T is best for command rate, though if you can get 1T out of your RAM kit then it may provide slightly better performance. Lower timings at 2T can outweigh higher ones at 1T.

Up the voltage as needed, do not use over 1.75V due to the PSC ICs and longetivity issues.

why are you trying to make your computer slower?

How is the second post from 5 days ago and the third only 3 days ago?

I feel I should bump....
