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 was a lot more active than the single-module listings, with some very significant price drops in evidence. The largest was a $78 price cut to the Mushkin EM3200 PC3200 2x1-GB matched pair kit, but there were also five other double-digit price decreases, including Crucial Ballistix Tracer PC4000 2x512-MB (-$30), OCZ PC3200 Platinum XTC 2x1-GB (-$17) and Corsair XMS PC3200LL 2x1-GB (-$12). There were only a few price increases, and none of note, as the largest was only a $5 jump to the price of an OCZ PC3200 PF 2x1-GB dual channel kit. The overall chart results definitely fell in favor of the consumer, as matched pair DDR dropped by an aggregate total of $157.
