The Reaper HPC is 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. The first modules to be incorporated with the new Reaper heatsink are rated at 800MHz and run at CL 4-4-4. Featuring an EPP (Enhanced Performance Profiles) programmed SPD, PC2-6400 Reaper HPC modules will immediately boot at the rated specs on the latest generation of NVIDIA® SLIâ"¢ chipsets. Although the OCZ Reaper HPC series was coined for enthusiasts, EPP eliminates the need for manual configuration and makes memory optimizations a household item for the complete range of consumers looking to maximize system performance through overclocking. As part of OCZâ?TMs line-up of premium memory, PC2-6400 modules are backed by a Lifetime Warranty and industry-leading technical support.
