Corsair has released 4GB Dominator memory kits that run at 1600MHz:
The dramatic increase in memory frequency from previous 800MHz DDR2 modules to the overclocked 1600MHz Corsair DOMINATORs allows a corresponding increase in memory subsystem bandwidth, which directly results in improved system performance. At the same time, advances in processor architecture and game design have moved the optimal memory content for a gaming-oriented system from 2GB to 4GB. Corsair and Dell worked together to produce module test procedures specifically tailored to provide a high speed 4GB memory subsystem with superior stability and greatly elevated clock frequency.
“The performance computing community is very aware of the improved game play that 4GB of memory offers, as well as corresponding improvements in task switching and program load times,” stated Andy Paul, President and CEO at Corsair. “Dell and Corsair completed many hours of testing and tweaking over many hardware and firmware revisions, and the result is a platform that is exquisitely tuned for performance and stability.”
“The XPS 7XX-series platform is the ideal place for Dell to showcase the best that PC performance hardware has to offer,” said Patrick Desbois, Dell XPS Gaming Engineering. “We had very aggressive performance goals for this platform, including the ability to run 4GB of overclocked main memory with rock-solid stability. Corsair’s DOMINATOR DDR3 modules were the only logical choice for the best-in-class performance memory required for the Dell XPS 730.”
