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 overall activity in the dual-channel DDR chart was not quite as good, and surprisingly, the single-module DDR listings showed more activity. There was only a single price drop to reach double digits, as the PNY Optima PC3200 2x1-GB kit fell by $16. The next largest price decrease was only $9 off the Kingston HyperX PC3200 2x1-GB matched pair, while a $7 price jump to pqi TURBO PC3200 2x1-GB was the biggest shift on the other end of the chart. This led to a stable week in dual-channel DDR, as the chart only fell by an aggregate total of $51, well back from the impressive $224 decrease we found at the end of March.
