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.
While the dual-channel DDR chart usually brings with it better news, this times it's actually a bit worse than what we found in the single-module DDR listings. But not much worse, as there were also three price drops, including a $10 decrease that hit G.SKILL PC3200 C2.5 2x1-GB. The number of price increases also jumped, doubling to ten, and included Crucial Ballistix PC3200 2x512-MB (+$17) and PNY Optima PC3200 2x1-GB (+$9). This created a different trend than we're used to in this area and the overall chart movement totaled a $29 increase, which more than wiped out the $23 aggregate chart drop we posted in the last guide.
