Memory maker Corsair has launched a pair of high-performance memory modules that not only ship with a specially design heat sink but can also be supplied with a clip-on cooling fan. The DDR 2 DIMMs run at 1,111MHz.

Dubbed the XMS 2 Dominator, the Corsair product line comprises two 2GB modules, one clocked at 1,111MHz, the other at 1,066MHz. The higher-speed version has a latency rating of 4-4-4-12-2T, while the other DIMM is rated at 5-5-5-15-2T, Corsair said.

The company claimed the DIMMs' heatsink maximises the dissipation of heat not only from the front of each of the module's memory chips but also heat flowing from the back of each chip via their connector pins.

To help move the heat away from the memory even faster, Corsair said it was offering an optional fan unit containing three 40mm fans to suck air up between memory chips and the DIMM circuit board and out over the heatsink.

Both DIMMs meet Nvidia's Enhanced Performance Profiles (EPP) specifications for auto-overclocking. The memory modules will ship early next month, Corsair said, priced at $600-650 for the PC28888 product and $380-400 for the PC28500 version. The add-on fan will cost $25. ®
