The number of dual-channel DDR platforms continues to increase, and has really created a subset of the memory market. The "matched pair" format is becoming increasingly 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, and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
The high-end matched pair DDR chart doubled the $80 aggregate price drop of the single-module DDR listings, and showed more individual double-digit price drops. The largest cuts were for 2x512-MB configurations, and these bucked the trend towards 2x1-GB dual channel kits receiving all the attention. Crucial Ballistix Tracer PC4000 2x512-MB fell by a whopping $71, while Crucial Ballistix PC4000 2x512-MB dropped $30 and Corsair XMS PC3200LL 2x512-MB received a $21 cut. In terms of individual brands, the Crucial Ballistix DDR kits were the most active by far, and bargain-hunters may want to dust off their wallets and nab a deal or two.
