    Something I realized was CPU benchmarks went up where as RAM benchmarks not so much. Perhaps this may explain using all 4 DIMMs does stress the CPU's IMC. Just saying :)

    Also the original specs for the DDR3-2133 Ram is 9-11-11-32 @ 2T w/ 1.6v and the XPM spec was 9-12-12-32-42 @ 1T w/ 1.6v. What I did was lowered the one 12 to 11. I plan on further tightenning up the ram more but at a later date.

    Running the DDR3-2133 at original timmings did not gain any extra performance boost for the Ram, but the CPU performance did get a mild gain, but not much. But by using the XPM specs this is what I got, better than the original.

    Nice review. I would like to see the G.SKILL Ripjaws X Series 16GB DDR3-2133 (8GB x 2) run at the 1866 (4GB x 4) - 9-10-9-28-2T @ 1.5v speed and see if their is any performance differences. Would make for a interesting comparison.
