DDR2 is the next generation of DDR memory. DDR2 memory features faster speeds, greater bandwidth, lower power consumption and enhanced thermal performance. Although DDR2 modules are the same physical dimension as DDR modules, the plug-in connector configuration is different and as such DDR2 modules are not compatible with PCs requiring DDR modules, and vice-versa. PNY manufactures DDR2 memory upgrades rated at PC2-3200, PC2-4200, PC2-5300 and higher. They are compatible with desktop and notebook computers and processors including Intel`s Pentium, Celeron, Centrino, AMD`s Athlon and Sempron Socket AM2 processors, and others. PNY upgrade modules are compatible with systems from Compaq, DELL, Gateway, HP, IBM and over 5000 other systems. Boost the performance of your PC. PNY memory upgrades will prove to be an outstanding value now and in the future.Price: $74.99
