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.
The dual-channel DDR chart is quite similar to the single-module one, with a lone significant drop and very little in the way of upward movement. The double-digit price cuts included the pqi TURBO PC3200 2x1-GB (-$20) and Crucial Ballistix PC3200 2x512-MB (-$11) matched pair kits, but the next-highest was only -$6. There were actually price increases in this chart, and although none hit double digits, a $9 jump in the price of Crucial Ballistix TR PC4000 2x512-MB did come close. This resulted in an aggregate chart drop of $45, which is much better than the $55 total chart jump we posted on our previous memory guide.
