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 also very active this week, but there are really two different scenarios taking place. In some cases, prices have spiked significantly, especially on some of the 1-GB DDR kits like the Kingston HyperX DDR. In many other areas, we find nominal price increases, along with several that remained unchanged, such as Geil PC3500 and PC4200 1-GB kits.
