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.
There was a bit more activity in the dual-channel DDR chart, but again, nothing that was too exciting. Five of the listings did fall by double-digits, but the range wasn't that great, and a $14 cut to the price of Ultra PC3200 2x1GB was the largest. This was followed by a selection of $10-$11 price drops, along with a set of smaller price decreases in the $1-$6 range. Only a single dual-channel DDR listing increased by a similar amount, as the price of a OCZ PC3200 Platinum 2x1GB kit jumped by $11. Our previous memory guide showed this chart dropping by an aggregate total of $36, or right on par with the $33 drop this week.
