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 tells a far different tale than the single-module chart, and overall pricing trends are definitely moving downward. And if we discount the bizarre $47 price spike to Corsair XMS PC4400 PT 2x512-MB (which was based more on low supplies than anything else) it was actually a nice week for matched pair DDR. There were quite a few individual price cuts to be found this week, but surprisingly, only the $18 cut to the price of OCZ PC4400 Gold 2x256-MB DDR registered in the double-digit range. It's still a good week overall for the dual-channel DDR kit market, and the majority of brands received some form of price break.
