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 held better news than the single-module DDR listings, and the $87 aggregate chart decrease is certainly a lot better than the $10 drop we found in the previous listings. Of course, numbers can be misleading - in this case, the main downward activity revolved around two matched pair kits. Crucial Ballistix PC4000 2x1GB fell by a whopping $70 while PNY Optima PC3200 2x1-GB received a $20 cut, and these two accounted for the vast majority of the dual channel DDR price drops. Price increases were virtually non-existent, with a $6 jump to OCZ PC3200 PF 2x1-GB being the largest.
