PC Perspective posted a review on the Corsair Dominator DDR3 1800MHz Intel XMP Memory

There's a lot to like about Corsair's new Dominator XMP 1800 MHz DDR3 modules. Just in terms of raw speed, the amount of memory bandwidth that DDR3-1800 offers is amazing. We would really like to see the timing issue addressed though for the XMP profiles -- if 7-7-7-20 was indicated then having the system run at 9-9-9-24 is a downer. Looking past that, the Intel XMP standard does in fact make the memory overclocking world easier and more accessible to users that are not comfortable addressing multipliers and timing settings.
