The dual-channel memory format is the standard for high-end performance systems, and is the de facto packaging for most DDR memory. The "matched pair" format has become very 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 (although 2x2-GB are emerging) and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
The dual channel DDR chart was more active than the previous listings, and true to form, the $130 total chart decrease almost doubled the single-module DDR results. This is still a bit lower than our last price update, where dual channel DDR managed to post almost $200 in total drops. There were nine individual price cuts that reached double-digits, with the largest hitting the Patriot PC4000 2x1-GB (-$22), OCZ PC3200 Performance 2x1-GB (-$21) and pqi TURBO PC3200 2x1-GB (-$20) matched pair kits. Unfortunately, there was some activity on the other end of the chart, and two listings - PNY Optima PC3200 2x1-GB (+$24) and Kingston HyperX PC3200 2x1-GB (+$10) - matched this feat.
