I would make my first priority getting the Cas latency as low as possible. Just keep dropping your cas and upping the voltage until is just won't post. Up the timings to see just how low you can get the cas latency. Then run memtest/prim95 for stability. (when running memtest I usually run once instance per ram dimm. (~ 250mbs))
Honestly though, You should first see if the differences made by overclocking are even worth it for you. Run Maxxmem benchmark in between each clock change to see if there are improvements. You get to a point, when overclocking, where you have to dump tons of voltage to get a little bit more over clock, "diminishing returns," and its just not worth it,or, not possible.
And I've know ram to be finicky. Able to run at really weird niche timings. So it can be really time consuming to find that sweet spot.OR, just run spec likee You do Edited by Acefire - 5/18/12 at 8:39pm
