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.
We usually get better news in the dual-channel DDR chart, but with the exception of a single price change, that did not happen this week. A $20 price drop on the OCZ PC3200 Platinum 2x1-GB matched pair kit did provide some good news, but that was it in terms of double-digit price changes. WINTEC AMPO PC3200 2x1-GB and pqi Power PC3200 2x1-GB both received $9 drops, but this was as close as the dual-channel DDR list could get. The largest price increase was also $9, as Corsair XMS PC3200LL 2x1-GB jumped by that amount. The overall chart movement was in line with these individual results and we posted a $35 total chart drop.
