Ram Timing Advice for new build

[Rumbled]

Can anyone explain tightening and losening up ram? I'm currently running Kingston Hyper X 1600MHz with 9,9,9,27 at 1.65v recommended timing and voltage. Also would it be faster to run 1300MHz with the CPU-Z recommended JDEC of 9,9,9,25? Thanks for the advice....

even in a benchmark program the difference between 9-9-9-25 and 9-9-9-27 probably wouldnt show up.

the RAM timings are numbers of clock cycles needed for a certain function. there are around 2 dozen numbers that effect RAM, but the main four (or sometimes 5; which have the most impact) are what you see in specifications.

this is what they actually mean http://en.wikipedia.org/wiki/Memory_timings

9-9-9-27 @1600 is definitely faster than 9-9-9-25 @ 1333 (~same timings, faster clocks)

You'd be hard-pressed to be able to tell the difference between a system running one versus the other, though, unless you were running a memory benchmark.

It's almost pointless to get super low-latency expensive RAM anymore.
