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.
We expected similar news in the dual-channel DDR chart, and while we did get most of it, there were a few noted anomalies. One is a massive $102 price cut that hit Kingston HyperX PC4300 2x512-MB, as some vendors are literally putting these modules on "fire sale", so get 'em while they're hot. A $29 drop to G.SKILL PC3200 C2.5 2x1-GB and $12 off Corsair Value PC3200 2x1-GB rounded out the double-digit pricing activity, while a $7 price jump to Patriot PC3200LL 2x1-GB was the largest increase on the chart. This amounted to a very healthy $142 aggregate chart drop, but without the $102 individual cut, it would have been business as usual in the matched pair DDR sector.
