It would probably be possible to squeeze a bit more out of these modules by increasing voltage, but that would void the lifetime warranty, something I am sure most of you wouldn't care to do.
Aside from having to modify my CPU heatsink to achieve proper clearance for the unusually tall Reaper modules, I had no issue with this memory kit. I experimented a bit with the heatpipe cooling on these modules, running the system with and without a 120mm fan that is positioned on the Tech Station to cool memory modules. Without the fan, the heatspreaders did get very warm - more so than I would have anticipated. Both the upper and lower sections of the heatpipe-based spreaders were warm, meaning the heatpipe technology is doing its job as advertised. With the 120mm cooling fan on, the modules remained generally cool to the touch.
Overall, the 6400 Reaper EB kit that offers everything you would look for in terms of high performance memory. The modules booted at the advertised timings and remained rock stable throughout testing. Overheating was not a problem thanks to the Reaper's heatpipe cooling, which channels heat to the upper deck of aluminum fins and effectively increases overall surface area. Overclocking came easily, as I was able to take these modules up to DDR2-930 at default timings and warranty-safe voltage. If you have proper clearance for these modules and are in the market for some new DDR2 memory, I encourage you to give the OCZ PC2-6400 2 GB EB kit a hard look.
OCIA.net has awarded the OCZ 6400 Reaper Enhanced Bandwidth kit our seal of approval.
