DDR3 is the next generation of DDR memory. DDR3 memory features faster speeds, greater bandwidth, lower power consumption and enhanced thermal performance. Although DDR3 modules are the same physical dimension as DDR2 and DDR modules, the plug-in connector configuration is different and as such DDR3 modules are not compatible with PCs requiring DDR2 modules, and vice-versa. Boost the performance of your PC. PNY memory upgrades will prove to be an outstanding value now and in the future
