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 displayed many of the same basic trends as the single-module DDR listings, but with a few notable changes. The most prominent is a $95 cut to the price of Crucial PC3200 2x2-GB, along with the lack of any double-digit price increases, both of which contributed greatly to the $164 aggregate chart drop. If you take away the above outliers, and a $31 drop to Corsair XPERT PC3200 2x512-MB, it was a fairly standard week for matched pair DDR. We also added in a few new listings, and with the largest price increase totally only $6, it's still good news for DDR buyers.
