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 was a lot more active than the single module DDR listings, as evidenced by the six double-digit cuts, culminating in a whopping $146 drop hitting the Kingston HyperX PC3200 2x1-GB kit. Naturally, the overall chart movement was also impressive, and dropped by a very healthy $270 this week. OCZ PC4000 EL 2x1-GB fell by $30 and Crucial Ballistix TR PC4000 2x1-GB dropped $27, and 2x1-GB DDR matched pair kits held down the top five positions on the "Price Change" column. There were some higher price levels to contend with, but only two reached the $12-$14 range, and there were only six price increases in total.
