With Vista and all of the new programs that like to eat up your system memory, the old 2GB sweet spot just is not cutting it anymore. To battle this problem, many manufacturers are producing 2x2GB memory kits that have two matched modules to run in dual channel for increased performance. With speed also comes heat and memory has for a long time, been overlooked when it came to cooling but now manufacturers see the need and have been designing heatsinks to keep your speed demons alive. Heat spreaders have been around for a bit now and have aided in passively cooling memory modules but some companies take it farther with radical heatsink designs and active cooling.
Corsair has found a way to combat this issue with their DHX memory heatspreader. DHX stands for Dual-Path Heat Xchange, which is made up of one heatsink attached to the memory chips and one attached to the PC Board to keep both components as cool as possible. Today we are going to look at the Corsair model number TWIN2X4096-6400C4DHX which is a 2x2GB set rated at 800MHz and runs at a lower latency of 4-4-4-12 with a voltage of 2.1v instead of the JEDEC specified timings of 5-5-5-18 at these speeds. This set also utilizes the DHX heat spreaders to combat the heat generated at these speeds.
The Corsair XMS2 DHX set is packaged in an easy to open blister pack, so that you do not accidentally damage the modules while trying to get them out. The front of the package is see-through, so you can see exactly what the memory and heat spreaders look like. There is the XMS2 DHX logo on the top, as well as the capacity specifications on the front. The back of the packaging explains what the DHX heat spreader is and what it does. There is also a section that explains about the optional active cooling fan from Corsair that can be used with the XMS2 DHX memory to lower temperatures even more, especially while overclocking. If you open the paper in the packaging there is a step by step guide on how to properly install the modules to aviod damage.
Once the modules are removed from the packaging we can get a better look at them. The DHX heat spreader is large and made of aluminum to aid is the dissipation of the heat created. The top of the heat spreaders uses a fin design so that air passing over them will remove the heat and out through the case exhaust fans using convection. One heat spreader is attached to the memory chips and one is attached to the circuit board to keep both parts of the module at optimum temperatures. With the optional cooling fans, this will also decrease the operating temperatures for faster and more stable overclocks. This set is a matched pair of modules rated at 800MHz with lower latencies of 4-4-4-12 at 2.1v.
Now that the memory is out of the packaging let's get to testing these monsters.
