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.
The news is even better in the dual channel DDR chart, and it includes a lot more activity compared to its single-module cousin. To start, we have five price drops that hit double digits, including a pair of $100 individual cuts. Kingston HyperX PC4000 2x512-MB and HyperX PC4300 2x512-MB both shaved a C-note off their retail prices, while Mushkin HiPerf PC3200 2x1-GB and Kingston HyperX PC4000 2x1-GB fell by $38 and $21, respectively. Once again, there is only a single double-digit price spike, with Corsair XMS PC3200 PRO 2x1-GB increasing by $21. The overall chart trends followed along with these individual price cuts, and the dual channel DDR listings posted an aggregate drop of $265.
