The Reaper (Cas 4) 4GB kit is designed to offer consumers a high end, high density kit, that is optimized for gamers who require both faster and more memory to power through the latest graphics intensive applications and games. The Reaper makes use of the HPC heatspreader, an innovative patent-pending cooling solution developed by OCZ to effectively minimize heat produced by high-speed memory. As heat rises into the thermo-conductive copper heat pipe conduit, it is dissipated through the strategically-placed compact aluminum fin array. By guiding performance-robbing heat away from key memory components, the unique Reaper HPC design helps facilitate improved overclocking performance, while improving longevity and stability of the modules.This high-density 4GB kit is ideal for running any enthusiast or profession system at maximum performance. At 800MHz, the 4GB Edition runs at tight 4-4-4 latency timings and offers unprecedented stability on the latest AMD and Intel platforms. As a Vista up-grader, the PC2-6400 4GB Cas 4 dual channel kit will provide maximum memory bandwidth and deliver the best possible gaming and productivity on Vista systems.
