Corsair Memory on Wednesday said that its engineers have managed to overclock the company’s Dominator GT memory modules from 2000MHz to 2533MHz in the labs. The company did not reveal whether the record breaking required usage of extreme cooling solutions, but stated that the modules worked in triple-channel mode, which means that the result can be practically used.


“When it comes to overclocking and memory, Corsair has proven – once again – that its engineering team truly is the best. As the new world record shows, Corsair’s modules are second-to-none in terms of performance, stability and quality,” said Kevin Conley, Vice President of Engineering for Corsair.

According to Corsair, 6GB Dominator GT triple-channel kit operated at 2533MHz with CL7 8-7-20 timings and unknown voltage setting on a system equipped with Intel Core i7 Extreme Edition model 975 processor and EVGA X58 3X SLI Classified mainboard.

In fact, 2533MHz is not exactly the highest speed achieved by Corsair’s DDR3 memory modules: in July ’08 the company already demonstrated a module running at 2580MHz with CL9 9-9-24 timings on an Intel X48-based mainboard. However, at that time the module operated in single-channel mode, which is not quite useful for multi-channel systems.

Triple-channel memory sub-system functioning at 2533MHz provides unprecedented bandwidth of 60.792GB/s, which should enable blistering performance in applications that depend on memory throughput.

While the results were obtained in a laboratory with premium components, they have chances to be repeated in actual systems by enthusiasts. Corsair Memory recently unveiled advanced thermo-electric cooling systems that are capable of cooling memory up to 20°C below ambient temperature. According to the company, when the thermo-electric cooling is combined with the company’s H30 water-block, the T30 allows for higher overclocking and greater memory performance and stability. In the Corsair Lab, the T30 was found to increase memory frequency overclocking by as much as 100MHz compared to standard cooling.
