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.
We get better news in the dual-channel DDR chart, where at least some listings received a double-digit price drop. There were four listings that hit that mark, including the pqi TURBO PC3200 2x1-GB (-$25) and Corsair XMS PC3200LL 2x1-GB (-$24) kits, which both exceeded the -$20 mark. There was only a single price increase of any consequence, as OCZ PC3200 Platinum 2x1-GB spiked by $9. But that was as far as the price changes went, and due to the greater number and depth of the price drops, the overall chart movement displayed an aggregate drop of $67.
