OCZ broke into the enthusiast memory market with specialized memory modules tailored for overclockers, and back then, things were simpler. Speed you see, was the only consideration. Today, performance memory is available at just about every corner you look and the maturity of DDR2 just means more choices to choose from. Still, OCZ continues to do their thing. Their FlexXLC series was a testament to their commitment to all the hardcore overclockers out there. However, if water cooling isn't your 'thing', or if you're just looking for something a little more inconspicuous, OCZ has you covered as well.
The OCZ Reaper HPC (Heat-Pipe Conduit) is the next best thing in their premium line up and unlike the FlexXLC, the Reaper HPC has a fully self contained cooling system thanks to its patent pending heat-pipe conduit design. These memory modules employ a larger heat spreader which is connected to a heat-pipe loop at the top to provide the extra cooling required to handle the heat from overclocking and the eventual high voltages used.
The Reaper HPC series comes in DDR2-800, DDR2-1066 and DDR2-1150 versions. The lower end DDR2-800 modules themselves have different variants for memory timing, but being enthusiast memory, the DDR2-1066 and DDR2-1150 models are the most sought after. These high speed modules carry a default voltage of 2.3V and OCZ's EVP (Extended Voltage Protection) warranty scheme to cover voltages up to 2.35V. Seeing how high these babies already run, it seems that even OCZ isn't comfortable risking warranty coverage above another 0.05V, so that might be a slight disappointment. The Reaper HPC also supports NVIDIA's SLI Memory technology with EPP (Enhanced Performance Profiles). Used with selected NVIDIA chipsets, these modules can run with optimized timing or overclocking parameters for better performance.
CPU-Z reports that the DDR2-1066 Reaper HPC memory is actually based on DDR2-667 chips and in fact, our motherboards detected it as 667MHz when set to default or auto. Now, we all know all performance memory above JEDEC standards are really hand picked and overclocked chips. However, it seems that OCZ has opted to use lower rated speed bin memory modules for the DDR2-1066 Reaper HPC. Will this affect performance or overclockability? You'll find out soon enough.
