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.
This week's high-end matched pair DDR price list shows real movement in some areas, while others remained pretty stable. The main price breaks came at the PC4000 level, with Corsair dropping significantly and Geil moving down nicely. The double-digit price spikes were the result of fewer vendors carrying these models, with Muskin PC3500 2x512-MB and OCZ PC4200 2x512-MB being hit the hardest.
