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 currently the 2x512-MB and 2x1-GB kits, and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
The matched pair DDR chart shows a lot more activity than the single module listings, and we're seeing significant movement on some 2x1-GB DDR modules. There were a total of four cuts hitting the double-digit range and all of these hit the 2-GB dual channel kits, there largest of which were Mushkin eXtreme PC4000 2x1-GB (-$24) and Crucial Ballistix TR PC4000 2x1-GB (-$20). Although the majority of listings showed no change, there were very few price increases, and none above $5. The matched pair DDR chart also showed an overall drop of $99, which is not exactly significant, but it sure beats the single module market.
