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 2x512-MB and 2x1-GB kits (although 2x2-GB are emerging) and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
As expected, the dual channel DDR listings show the same basic trends, only with higher dollar amounts due to the matched pair format. The total chart movement amounted to a $186 increase, or just over double that of the single module chart, and well back of the $349 aggregate chart jump of our last guide. In terms of individual price activity, only one matched pair kit received a double-digit price drop, as OCZ PC4000 EL XTC 2x1-GB fell by $13. But that's it as far as significant price cuts go, but we're just getting warmed up on the price increase side of things. Here, we find a grand total of nine double-digit spikes, including five that hit $20 or more. The largest jumps included the Patriot PC4000 2x1-GB (+$27), Mushkin eXtreme PC4000LL 2x1-GB (+$28), and Corsair XMS PC3200LL 2x1-GB (+$36) dual channel kits.
