The number of dual-channel DDR platforms continues to increase, and has really created a different section of the memory market. The "matched pair" format is becoming increasingly 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, and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
Usually, the trends we have in the single module DDR listings are similar, and even extended, to what we find the dual channel DDR price list. Unfortunately, that is not the case this week, and the small drop in the previous DDR chart has turned into $19 overall chart increase in the matched pair DDR listings. There was only a single price drop that reached double digits, as Corsair XMS PC4000 2x1-GB fell by $16, although there were several smaller price decreases that followed. What really put the monkey in the wrench was the $51 price spike that hit Crucial PC3200 2x2-GB, which more than cancelled out the lower price trend.
