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 was more active than the single-module listings, and this week it posted an aggregate chart decrease of just under $200. The individual price changes were also deeper, and in addition to the eight double-digit cuts, we have impressive price drops like PNY Optima PC3200 2x1-GB (-$57), Mushkin EM3200 PC3200 2x1-GB (-$38), Mushkin HiPerformance PC3200 2x1-GB (-$35), and Corsair XMS PC3200LL 2x1-GB (-$33). Unfortunately, there were a few similar price increases, and two in particular caught our attention: a $21 price jump to Kingston HyperX PC4000 2x1-GB and a $30 spike that hit Corsair XMS PC4000 2x1-GB. Overall, it is still a very good week to buy into matched pair DDR, especially as retail supplies are higher than over the past few months.
