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 duplicates some of the trends we saw in the single-module chart, but shows larger price shifts with a few of the DDR kits. OCZ PC4400 Gold 2x512-MB dropped a whopping $24, while OCZ PC3700 EL 2x512-MB, Geil Ultra Platinum PC3500 2x512-MB, and Corsair XMS PC2700LL 2x512-MB all posted double-digit price cuts. Although OCZ PC4200 EL 2x512-MB bucked the trend and jumped a hefty $35, the vast majority of the price changes were in the consumer's favor, and overall price changes were about equal with the single-module counterparts.
