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 2x2GB are emerging) and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
There was a bit more activity in the dual-channel DDR chart, along with several price changes that hit the double digit range. Four of these were price decreases, including the Corsair XMS PC3200LL 2x1GB (-$17), Ultra PC3200 2x1GB (-$15), Kingston HyperX PC3200 2x1GB (-$11), and Centon PC3200 2x1GB (-$10) listings. Only a lone price increase hit similar levels, as the Geil PC3200 Value 2x1GB kit jumped by $10. The led to an overall chart decrease for the week, as matched pair DDR dropped by an aggregate total of $40.
