When it comes to these memory modules, what's better, running them at 1866 with timings 9-9-9-24 1T or 2133 with 9-10-10-27 1T? I got a 2500k running on an Asus P8P67 Deluxe @ 4.8GHz. What kind of program can I use to see the difference while benching them? Thanks on advanced and sorry for the noob questions.
