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 matched pair DDR chart didn't have a monster $100+ price drop to support itself, but still managed to post five double-digit cuts, with some very significant ones as well. Kingston HyperX PC3200 2x512-MB fell by $54, Geil Ultra Platinum PC4400 2x512-MB received a $42 cut, and Geil Ultra Platinum PC4200 2x512-MB dropped by $33. The total chart drop was only $158, and failed to match that of the single-module DDR listings, possibly due to the Corsair XMS PC3200LL 2x512-MB and OCZ PC4400 EL 2x512-MB kits jumping by $13 and $27, respectively.
