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.
There was more activity in the dual channel DDR chart, and this held mostly good news for consumers. There were five price drops that hit double digits, including a $32 cut to OCZ PC3200 Platinum 2x1-GB and a $19 decrease in the price of Super Talent PC3200 2x1-GB. The overall chart fell by $72, with most of the downward price movement hitting in the 2x1-GB range - these DDR kits comprised the vast majority of the lower-priced listings. The news was also very good on the price increase side of things, as only a single DDR2 matched pair kit increased from our last guide. Of course, this was a $33 spike to the price of PNY PC4400 2x512-MB, but as long as you steer clear of that landmine, it's a pretty good update for DDR2 buyers.
