OCZ makes some bold claims about its 4GB PC2-6400 ReaperX memory. It states that this 2x2GB kit offers ‘high frequencies and aggressive bandwidth for maximum system stability. Rated at DDR2-800 with 4-4-3 timings, the PC2-6400 ReaperX provides exceptional latencies for the extreme enthusiast and gamer.’ Well there’s plenty to get our teeth into there but let’s start with the cosmetic looks of the memory and the construction of the heatsink.
We’ve previously been impressed by OCZ Reaper HPC (Heat Pipe Conduit) memory. Reaper modules lift a secondary heatsink above the main PCB using a small tubular copper heatpipe that is clamped between the two heat spreaders. This results in a convoluted heat path that leads from the memory chips to the heat spreaders, on to the heatpipe and thence to the secondary heat sink. And that must be good because it’s rare that I get to say ‘thence’ in a review.
ReaperX shortens the heat path by clamping a broad flat copper heatpipe directly to each bank of memory chips using the two halves of the heat shield. These heatpipes run across the module of memory and then bend around through 180 degrees to run back across the top of the memory. These upper sections carry aluminium fins to dissipate the heat so the heat goes directly from the memory to the heatpipe and on to the air inside your PC case in a surprisingly effective way. In fact the memory consistenly hovered around 35-40 degrees Celsius, which is mightily impressive.
It’s worth pointing out that the two heatpipes don’t join together even though it appears that they do in the photos. When you install the memory it’s important to be careful as it’s all too easy to press on the delicate heatpipes rather than the body of the module and cracking the heatpipes would render them useless. The other downside to the design is that the heatpipe system makes the modules rather thick so you can’t populate two adjacent memory slots. As most motherboards have four memory slots you’ll be limited to installing a pair of modules in two of the slots which might be a problem with a 2x1GB memory kit but it’s unlikely to cause you a problem with this 4GB kit unless you are determined to have 8GB of RAM in your new PC.
