Although none of Intel's Nehalem-derived CPUs officially supports DDR3 memory faster than 1333MHz, a press release hit my inbox this morning announcing that Kingston has a new 4GB, dual-channel HyperX kit capable of running at a whopping 2400MHz. Claimed to be the world's fastest memory, the KHX2400C9D3T1K2/4GX kit has already gained Intel XMP certification (PDF) for Core i7 processors. Of course, some sacrifices had been made on the path to 2400MHz. The HyperX DIMMs were certified at relatively high 9-11-9-27-2T timings and require 1.65V.
Anyone itching to get their hands on these latest HyperX DIMMs will have to wait until the second quarter of this year. There's no word yet on price, but I wouldn't expect the modules to be cheap, especially if Kingston is able to hang onto the "world's fastest" crown. Intel certified Corsair's 2333MHz Dominator GTX1 modules earlier this year, and those cost a cool $200 per 2GB DIMM. For reference, the 4GB DDR3-1333 kit featured in our latest system guide sells for just $105.
