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 the 2x256-MB and 2x512-MB 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 listings showed approximately double the activity of the single module chart, and there was a bit more variety in the brands and sizes that received the larger price cuts. Kingston HyperX PC3700 2x512-MB dropped by $33, Mushkin PC3200 L1 2x512-MB dipped by $22, while OCZ PC4000 EL 2x256-MB and Mushkin PC3200 Blue 2x512-MB received price cuts of $16 and $15, respectively. There was also only a single double-digit price jump, as Corsair XMS PC4000 2x512-MB spiked by $16. Overall this is another great week for dual-channel kit buyers, and we continue to see price drops in certain areas.
