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.
Our dual channel DDR chart shows slightly different pricing trends, but first impressions can be deceiving. The overall activity resulted in a total chart decrease of $50, but many of the dual channel DDR listings showed price changes similar to the single-module DDR chart. The only difference was a large $76 price drop that hit Crucial PC3200 2x2-GB, which was the main source of the total $50 chart decrease. There was only one other double-digit price cut, as Crucial Ballistix TR PC4000 2x512-MB fell by $11, while Mushkin eXtreme PC4000LL 2x1-GB jumped $29 and OCZ PC3200 Platinum 2x1-GB increased by $10. If you remove those outliers, the majority of matched pair DDR showed no price change at all.
