OCZ ReaperX HPC 4GB PC2-6400

Examination:

Memory cooling is one of the areas where OCZ Technology has been at the constant forefront of innovation and even through expanding their product lines to include flash media, power supplies, and most recently their Neural Impulse Actuator, they are still coming up with new ways to cool system memory. The ReaperX HPC looks vastly different from the original Reaper due to its dual copper heat-pipe design and much larger aluminum fin array. Each heatpipe runs along one side of the memory PCB, so that each memory IC is able to come in direct contact with one heatpipe. This too is far different from the original Reaper design where the heatpipe was just glued to the top of the heatspreader.

The surface area for the aluminum fin array on the ReaperX is much larger, to the point that it's almost doubled. Due to its design though it prevents memory modules from being installed side-by-side. The ReaperX memory may also have problems being installed in a low-profile chassis.

The sticker on each memory module contains the part number (OCZ2RPX800EB4GK), rating (PC2-6400), memory capacity (2GB Dual CH), type (Reaper X Edition EB), and timings (4-4-3). The ReaperX DDR2-800 modules have an EVP (Extended Voltage Protection) rating of 2.2V, which means you can push up to 2.2V to this memory while overclocking before voiding its lifetime warranty. Like the original Reaper modules, this memory also supports NVIDIA's Enhanced Performance Profiles.
