Here's something to make bandwidth aficionados swoon. Corsair claims to have passed Intel's Extreme Memory Profile certification process with new Dominator GTX1 DDR3 modules clocked at an eye-popping 2,333MHz—purportedly the fastest to have gotten Intel's stamp of approval. As if that weren't fast enough, Corsair independently guarantees the same modules for operation at an even speedier 2,400MHz.
If my math is right, 2,333MHz yields maximum theoretical bandwidth of 18.7GB/s per module, or just over 37GB/s for two DIMMs piping data through to a dual-channel memory controller. Not bad at all. Corsair says it achieved the clock speed with 9-11-9-27 timings and a Nehalem-friendly 1.65V voltage setting on a Gigabyte GA-P55A-UD4P motherboard. (Any higher than 1.65V, and Intel warns that users could damage their Core i5 or i7 processors.)
Hitting those settings involves having modules individually hand-screened and tested on "multiple high-performance Intel P55 chipset platforms," Corsair points out. The company then slaps on one of its fancy DHX+ heatsinks and sells each 2GB Dominator GTX1 module for $200 on the Corsair Online Store. So, you'll have to part with $400 for a 4GB kit—almost four times the price of the firm's own 4GB DDR3-1600 XMS3 offering.
