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 single-module DDR, but like many things in life, it did not automatically translate into a positive trend. In fact, get ready for some bad news, as there were three price drops and only one of them managed to hit double digits. The price of Mushkin EM3200 PC3200 2x1-GB tumbled by $17, but compare that to six similar price increases, including price jumps to Kingston HyperX PC4000 2x1-GB (+$22) and pqi TURBO PC3200 2x1-GB (+$15) matched pair kits. The overall chart actually increased by an aggregate total of $59, a far cry from the -$84 total decrease we posted last time out.
