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 showed a lot more activity than we saw in the single-module chart, and the overall shift was far more significant. There were a few double-digit price cuts this week, including a $26 drop to OCZ PC4200 EL 2x512-MB, and a $23 cut to Corsair XMS PC2700LL 2x512-MB. There were also virtually no price increases on DDR kits, and the number of cuts outnumbered the modules that did not change in price. Overall, this is a pretty good week for matched-pair DDR kits, especially if you're buying where the most significant cuts hit.
