The dual-channel memory format is the standard for high-end performance systems, and is the de facto packaging for most DDR memory. The "matched pair" format has become very 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 2x512MB and 2x1GB kits (although 2x2GB are emerging) and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
We found very similar trends in the dual-channel DDR chart, and it was even more accelerated here. Other than a hefty $27 drop to the price of a Kingston HyperX PC3200 2x1GB kit, it was a dead zone for lower priced DDR modules. Not so at the other end of the chart, as four of the matched pair listings showed double-digit price jumps. These included the Ultra PC3200 2x1GB (+$20), OCZ PC3200 Platinum XTC 2x1GB (+$10), G.SKILL PC3200 C2.5 2x1GB (+$10), and G.SKILL Value PC3200 2x1GB (+$10) kits, which helped drive the overall chart to an aggregate increase of $47.
