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 dual channel DDR chart is a lot more active than the single-module DDR listings, and the $95 aggregate chart drop is more than four times larger. This is still back from the -$174 we posted in our last update, but the five double-digit price cuts were certainly good news. The largest included Corsair XMS PC3200 XPert 2x1-GB (-$31), Corsair XMS PC3200 PRO 2x1-GB (-$25) and OCZ PC3200 Performance 2x1-GB (-$16) matched pairs. On the other end of the chart, there was only a single price increase that even registered, as pqi TURBO PC3200LL 2x1-GB spiked by $23 this week. That was the worst of it, as the next largest increase was only $5.
