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 displayed similar trends, but the price decreases were greater in number and cut a bit deeper as well. The largest was a $13 price drop to OCZ PC3200 Platinum 2x1GB, and this was accompanied by several smaller cuts in the $2-$8 range. Thankfully, the price increases were almost nonexistent - we counted just four total - and the largest was only an $8 spike to the price of Kingston HyperX PC3200 2x1GB. This still resulted in a very sedate week for dual-channel DDR prices, with the chart dropping by an aggregate total of only $32.
