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 was a bit better in the dual channel DDR chart, and at least there were a few noticeable price drops and potential deals for interested buyers. The chart showed four double-digit price cuts, including Kingston HyperX PC4000 2x1-GB (-$30), Crucial PC3200 2x2-GB (-$23), Corsair XMS PC3200 XPert 2x1-GB (-$21), and Crucial Ballistix Tracer PC4000 2x512-MB (-$16). There was a bit of activity on the other end of the chart, as both Corsair XMS PC3200LL 2x1-GB (+$20) and Corsair XMS PC4000 2x1-GB (+$28) jumped by more than $10. Although there were fewer price increases than decreases, the aggregate chart drop was only $39, and the majority of listings showed little or no change.
