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.
The dual-channel DDR chart usually shows more activity than its single-module counterpart, but this was not the case. Instead, we find almost a mirror image of consistent pricing, and the individual changes were even smaller. A pair of $7 price cuts to the A-DATA PC3200 2x1GB and Kingston Value PC3200 2x1GB matched pair kits amounted to the most significant drops we could find. The price increases were even lower, with a $7 jump being the largest in the chart. The overall DDR trends followed right along, and showed an aggregate chart drop of only $10.
