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 held better news than the single-module DDR listings, and posted a $126 aggregate chart decrease, which is very consistent with the $130 overall drop in our previous update. Naturally, the price decreases outnumbered the increases, and there were eight drops that hit double digits. The largest were a $27 cut to the price of PNY Optima PC3200 2x1-GB and a $25 drop to Patriot PC3200LL 2x1-GB. The remainder of these drops were in the $10-$15 range, and mostly affected 2x1-GB kits. On the other side of the coin, there was only a single double-digit increase, and that was only a $10 jump to the price of Crucial Ballistix Tracer PC4000 2x512-MB.
