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 news does not get any better in the dual channel DDR listings, and true to form, these essentially double-up the single module chart trends. The total chart movement amounted to a $349 price increase, or a $100+ jump compared to our previous update. There was not even one price drop that hit double digits, and in fact, only a single price drop even graced our dual channel DDR chart. On the price increase side of things, there was a ton of activity, including a whopping twelve double-digit spikes and seven that exceeded $20. Some of these increases were quite significant, including a $51 jump to the price of Crucial Ballistix TR PC4000 2x512-MB and a $64 price spike that hit Crucial PC3200 2x2-GB.
