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 2x2GB are emerging) and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
We usually find additional movement in the dual-channel DDR chart, and the trend continues again this week. Still, the price drops weren't excessive, but we did have two that reached double digits, as PNY Optima PC3200 2x1GB and OCZ PC3200 Platinum XTC 2x1GB received cuts of $15 and $10, respectively. As in the single-module listings, a single $8 price jump was the only real price increase in the chart, but this time it was Corsair XMS PC3200LL 2x1GB that showed the increase. The overall pricing movement followed right along, and the listings displayed a total chart drop of $46.
