Corsair Memory, one of the leading suppliers of high-end memory modules, on Thursday announced its fastest memory modules to date. The new Corsair Dominator GTX is specifically tailored for Intel Core i7/i5 “Lynnfield” central processing units (CPUs) and will not show its extreme capabilities on triple-channel memory sub-systems.


"Corsair Dominator GTX modules are the most tightly-screened, highest-quality and fastest DDR3 memory modules in the world, and we look forward to seeing what the enthusiast and overclocking community can do with these exciting new products,” Kevin Conley, vice president of engineering at Corsair.

Corsair Dominator GTX 2GB memory modules are rated to perform at 2250MHz (2.25GHz) with CL8 8-8-24 with 1.65v voltage setting in dual-module configurations with LGA1156 microprocessors. However, once four of such DIMMs are installed, their clock-speed drops to 2133MHz with the same timings. Corsair claims that three Dominator GTX modules will also operate at 2133MHz with CL8 in triple-channel mode with LGA1366 chips, however, in six-DIMM configurations they will only be able to operate at 1800MHz with CL6 6-6-18 timings.

The new Dominator GTX memory modules are also compatible with AMD’s AM3 platform, but they hardly bring a lot of advantages for AMD Phenom II microprocessors as Corsair guarantees only 1800MHz clock-speed with CL6 6-6-18 latencies in two module mode and 1750MHz frequency for 4 DIMM configurations.

The Dominator GTX modules use Corsair's DHX+ heatsink and are supplied with extra-tall cooling fins to maximize heat dissipation. The part number for this module is CMGTX2, and it is sold as a single module, allowing enthusiasts to purchase two modules for dual-channel configurations or three modules for triple-channel configurations. For the highest performance and frequency scaling, Corsair recommends using the GT Airflow fan with tall mounting brackets, which is also available from the Corsair Online Store.

The CMGTX2 is screened by hand, in multiple passes, by Corsair's lab in Fremont, California, and availability will be extremely limited, according to the manufacturer. It will be launched exclusively on the Corsair Online Store on December 8, 2009, at 9AM PT, and will be sold on a first come first served basis.
