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.
Although single-module DDR is showing very consistent pricing trends, the dual channel DDR market is humming right along. In fact, this looks more like the DDR2 chart, as we find an aggregate chart drop of $422. This is an exceptional total, as our last guide had an overall drop of only $52. There was a host of individual price drops, including thirteen that hit double digits. The largest were for PNY PC4800 2x512-MB (-$85), PNY PC4400 2x512-MB (-$84), OCZ PC3200 Platinum XTC 2x1-GB (-$34), and Corsair XMS PC3200LL 2x1-GB (-$34) matched pair kits. There were only two price jumps of any kind, and these were near-meaningless increases of $1 and $5.
