Good to see Crucial back in OC after a few years of abstinence (apart from using PSC ) - but in one thing the tester is definitiely wrong, Intel is not more forgiving on mems, it is definitely no match for 990X with 8xxx Bulldozer, so if these mems run nearly as well on 1155 or 2011 will have to be tested. Times of Intel supremacy on mem compability and clocking are long over
