Hothardware posted a review looking at 5 high-speed DDR3 memory kits.

Quote from the review: "We‘re writing to let you all know that we’ve just posted a new article at HotHardware in which we rounded up a handful of high-speed DDR3 memory kits. We got our hands on five, dual-channel, 2GB kits from Corsair, Kingston (2), OCZ, and Super Talent each with different rated speeds and timings, ranging from 1333MHz to 1800MHz.
Our intent was to show you how performance is affected by different clock speeds and timings using Intel's P35 chipset with a processor that has a 1333MHz front side bus speed."
