The number of dual-channel DDR platforms continues to increase, and has really created a subset of the memory market. The "matched pair" format is becoming increasingly popular, as these DDR module kits are perfectly suited for the requirements of high-end dual-channel DDR operation, and are a much safer buy than purchasing one module now and hoping to match it up later. The most popular configurations are the 2x256-MB and 2x512-MB kits, and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
The high-end matched pair DDR list is a bit more active than the single module prices, but again, the price cuts are limited to select areas. Corsair XMS PC3200LL 2x512-MB received a nice drop this week, and many of the Geil Platinum Ultra matched pairs dropped quite substantially. This week also sees the introduction of Kingston HyperX PC4300, which has become more visible at the larger online retailers.
