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 chart was a real mixed bag this week, and the overall chart actually trended upwards to the tune of +$15. That isn't to say there weren't deals to be found, as three dual channel kits, Crucial Ballistix PC4000 2x1-GB (-$36), OCZ PC3200 EL 2x512-MB (-$13) and OCZ PC4800 EL 2x512-MB (-$12), showed nice downward movement. But with a total chart increase, there must be some activity on the other end of things, and a whopping $50 jump to the price of Crucial Ballistix Tracer PC4000 2x1-GB certainly did its fair share of damage.
