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 situation was a slightly better in the dual-channel DDR chart, where we at least found a pair of double-digit price cuts. Kingston HyperX PC3200 2x1-GB fell by $15, while Corsair XPERT PC3200 2x512-MB shaved $13 off its price, and gave us the only real price changes in the entire DDR list. Thankfully, the price increases were in line with previous trends. Only two module listings showed higher prices, with a $4 spike to A-DATA Vitesta PC3200 2x1-GB being the largest. This translated into a total chart drop, with it falling by $55 for the period.
