what do i need to change to tighten timings?

post #1 of 7
Thread Starter 
want to go from a 1600mhz cas9 to cas8 or maybe cas7. Im leaving this OC last because im told it makes the least of difference. basically i got 9-9-9-24, im supposed to have it 8-8-8-22? And im supposed to change Dram voltage and qpi/vtt to accomdiate? Also how to test these values?

Start by dropping to 8-8-8-22-1T, keep the DRAM voltage below 1.6 and run Prime95 to check stability. I also like to run at least two passes of Memtest86+.

why below 1.6? i think you mean 1.65 right? how about i just leave the voltage at default, surely such a slight change in timings cant be overly demanding.

To start out, I would try to keep the voltage as close to 1.5 as possible. There is a chance that it will work fine at those timings on stock voltage. Personally, if it took over 1.6v to get stable, I wouldn't bother with it as the benefits of overclocking memory are marginal at best and are only noticeable in benchmarks.

one other question, is it worth going from 1443mhz to 1804mhz?

It's highly unlikely that you'll be able to tighten timings and increase the clockspeed. Often people actually loosen the timings to bump up their clocks.
