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 price list is a bit more active than the singe module listings, and overall prices are moving down. Although there were a few isolated price increases, there were also some heavy cuts such as Kingston HyperX PC4000 2x512-MB and Kingston HyperX PC3700 2x512-MB dropping $41 and $25 respectively. Most of the higher prices were due to availability, and as many of our usual vendors were out of stock, we were forced to move down the line and take a real hit in the retail price.
