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 mirrored the single module listings in some ways, most notably the $79 price cut to a pair of 512-MB Geil Ultra-X PC4400 modules, or just a bit more than double that of a single module. There were also seven double-digit cuts in the dual channel DDR listings, including $14 off both OCZ PC3500 EL 2x512-MB and OCZ PC4800 EL 2x512-MB. The overall price chart shift resulted in a total drop of $144, again, almost double that of the single module chart, and there were no significant price increases at all.
