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 also a very active part of the memory market this week, and it posted an aggregate chart drop of $135, and like the single module listings, there were quite a few individual price cuts to report. Crucial Ballistix PC4000 2x1-GB dropped by $89, OCZ PC4200 EL 2x512-MB fell $38, and gigaram Mach 1000 PC3500 2x-1GB shaved $31 off its retail price, but Crucial again threw a monkey wrench into the works with a whopping $52 price spike to their Ballistix Tracer PC4000 2x1-GB dual-channel DDR kit.
