I recently posted https://www.reddit.com/r/overclocking/comments/1ryhiru/advice_for_ram_overclocking/ looking for help which has been appreciated! However, even with better timings the latency did not change on memory. I have PBO enabled with a +200 offset and -15 with Curve Optimizer if that helps. Any ideas why? I ran Prime95 Large FFT and Y Cruncher for an hour each with no crashes/errors.
