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.
The dual-channel DDR chart showed greater overall activity, but this was mostly due to a single listing. The overall chart dropped by an aggregate total of $84, more than double that of the single-module DDR listings, but numbers often do not show the whole picture. That is because the price of Corsair XPERT PC3200 2x512-MB fell by an amazing $79, shaving more than half off its original price. The next largest drop was only a $19 price cut to Mushkin EM3200 PC3200 2x1-GB, and after than, only $5. There were only two price increases of note, as Patriot PC3200LL 2x1-GB increased $11 and OCZ PC3200 Platinum XTC 2x1-GB jumped by $17.
