Corsair says ”Dominator GT is the ultimate performance memory solution within the Dominator product line. Limited to only extremely high memory speeds, Corsair Dominator GT only uses highly screened IC’s to guarantee performance and over-clockability. Using ultra efficient Dual-path Heat Xchange (DHX) cooling technology, Dominator GT DDR2 and DDR3 memory modules also ship with the Airflow Fan to maximize heat transfer away from the modules — all the while being stable and reliable. With removable heat sinks, Corsair Dominator GT DDR3 and DDR2 memory modules can even be outfitted with additional upcoming accessories with enhanced features”.
