It took a few months, but Corsair has outdone itself again with the launch of its new 2GB Dominator GTX4 DDR3 memory. In January, the company introduced DDR3 RAM rated for up to 2400MHz, and that topped its 2000MHz sticks, but its latest offering promises to operate at 2,533MHz with timings of 9-11-10-30 and 1.65V -- perfect for P55-based machines.

Just like the 2,400MHz GTX1, GTX4 modules are individually tested by hand at Corsair's Freemont, California lab. The RAM ships with a lifetime warranty for the very special introductory price of only $325. While you're at it, you might as well go the full mile and get the company's Airflow 2 GTL fan, which is recommended for optimal performance.
