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 right where we expected, almost doubling the price decreases we found in the single-module listings, and posting an aggregate chart decrease of $148. This spells very good news for consumers, especially as price levels have been mostly consistent. There were six price decreases that reached double digits, including two that surpassed the $40 level - Corsair XMS PC4000 2x1-GB fell by $56 and Kingston HyperX PC3200 2x1-GB dropped $42. The matched pair listings also showed more diversity in the price drops, featuring Corsair, Kingston, Super Talent, G.SKILL, and pqi branded DDR at the top of the list. There were only two price increases, and discounting a $1 jump, the $24 price spike to Geil Ultra Platinum PC4000 2x512-MB was the only noticeable one this week.
