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.
Since the dual channel DDR listings essentially double-up the single module charts, it's appropriate that the aggregate chart shift amounts to +$193 this week. This is actually down a bit from the +$212 we posted in our last price update, but even so, it is hardly good news for memory buyers. At least there was one significant price drop, as Crucial PC3200 2x2-GB shaved a healthy $57 off its retail price. That is the end of the good news for matched pair DDR, as there was a host of price increases, including an incredible fourteen double-digit spikes, and four that topped the $20 mark. This last set included the OCZ PC4000 EL 2x1-GB (+$29), Mushkin PC3200 2x1-GB (+$23), OCZ PC3200 Titanium 2x1-GB (+$21), and Corsair XMS PC3200XL 2x512-MB (+$21) kits.
