"OCZ has put together a very interesting 4GB DDR2 memory kit, namely because these modules feature heatpipes and a large aluminum fin heatsink. The ReaperX HPC heatsink system draws heat way from the DDR2 BGA DRAM Modules, allowing system airflow to do all the work silently. The OCZ PC2-6400 ReaperX HPC Enhanced Bandwidth dual channel memory kit is 4GB in capacity, and it retails for a competitive price. This 4GB kit of PC2-6400 memory kit operates at DDR2-800 speeds with timings of 4-4-3-15."
