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.
Once again, the dual-channel DDR chart was more active than the previous DDR listings, and lived up to its name with an aggregate chart decrease of $98, or exactly double that of the single-module DDR chart. Two price drops really stood out, as the Kingston Value PC3200 2x512MB (-$29) and OCZ PC3200 Platinum XTC 2x1GB (-$18) kits fell by double digits. There was a long line of smaller $3-$9 drops, and only a single matched pair kit increased in price, but that a $13 spike to the OCZ PC3200 Platinum 2x1GB kit.
