KHX:DDR3 - DDR3 is the next generation of DDR memory technology. It is an evolution of DDR and DDR2 memory technology that delivers higher speeds (beyond 1333MHz), lower power consumption and heat dissipation. It is not backwards compatible with DDR2 or DDR based motherboards, due to incompatible module connection, voltage and DRAM technology. DDR3 HyperX is available now in speeds PC3-1375 and PC3-1500.
