The number of dual-channel DDR platforms continues to increase, and has really created a different section 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 listings offered significantly more activity than the single module listings, but with the lack of activity in our first chart, it is still not a rousing endorsement. There were three double-digit price drops, as OCZ PC3200 Platinum 2x1-GB fell by $22, while Corsair XMS PC3200LL 2x1-GB and Corsair XMS PC4000 2x1-GB received cuts of $21 and $13, respectively. On the other side, there was only a single noticeable price increase, as Corsair XMS PC3200LL 2x512-MB jumped by $11. The overall chart movement also reflected this, and the total price changes amounted to a $58 drop.
