I don't know the exact memory kit you're using, but lets say for example your memory is rated for 3200MHz with 16-18-18-38 latencies. Those latency timings are the timings I'm referring to. So if you lower the speed to 2666MHz, at the stock 1.35v the RAM is rated for, you may very well be able to lower those timings to 15-16-16-35. This makes your memory perform faster. And typically the higher the speed (MHz) the higher those latency numbers get. So they are scale-able. But just for the sake of getting the system running, I would set your speed and put the rest on AUTO and make sure eveything is working just fine. Later on you can go in and fine tune the memory and see what works and what doesn't. Setting the latency too low may cause...
