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 situation was a bit better in the dual-channel DDR listings, and here we found more activity than the single-module chart. There were six price drops that hit double digits, including Geil PC3200 Value 2x1-GB (-$35), Mushkin EM3200 PC3200 2x1-GB (-$30) and Patriot PC3200LL 2x1-GB (-$20). A single price increase tried to rain on the parade, as Corsair XMS PC3200 XPert 2x1-GB jumped by $38. Even so, the overall chart movement went in the right direction, and the dual channel DDR listings posted an aggregate drop of $199. This was a bit lower than the -$178 and -$136 overall decreases we posted in the past two price guides.
