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 has a bit more action than the single-module chart, but again, it's a case of some pretty significant cuts skewing the overall price changes. The Kingston HyperX PC3700 2x512-MB kit doubled up the single-module price cut to $60, and OCZ PC4200 EL 2x512-MB also dropped a healthy $31 as well. There were a few $8-$10 price drops to report, but we also have similar price increases that do much to offset the lower price movement. The overall price change was much larger than with their single-module counterparts, outranking it by over 3 to 1.
