Core i7-900 users get 12GB DDR3-1600 kit
 

With the release of its LGA1156 Core i5 and i7-800 processors, Intel has clearly relegated the Core i7-900 series to the high end. So, it stands to reason that you'd want to trick out a Core i7-900 system as much as possible—perhaps, say, with Kingston's latest HyperX memory kit, which delivers a whopping 12GB of blazing-fast DDR3 memory.

The new Kingston HyperX 1600MHz 12GB triple-channel kit includes six modules, with each module rated for operation at a peppy 1600MHz with 9-9-9-27 timings and 1.65V of juice. Kingston says the memory supports Intel's Extreme Memory Profiles, so getting it to run at those specifications shouldn't involve any tinkering.
