My geil won't run @850mhz on it's 4,4,4,12 optimal timings. The motherboard sets it at a default of 5,5,5,18, if I change it to this speed, it runs fine @850. Is there a middle ground in terms of timings that is a little faster than the latter, but still means it runs fine?
But unless you are looking at benchmarks, the difference is negligible.
