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.
The dual-channel DDR chart displayed very similar trends, and we found a nice selection of both price increases and decreases. Unfortunately, there were no double-digit price drops, and the largest decrease was only $9 off the price of a Geil PC3200 Value 2x1GB dual channel kit. The next on the list was only a $4 cut, while on the price increase side, an $11 price spike to the WINTEC AMPO PC3200 2x1GB kit was followed up by a trio of smaller $5 increases. This also meant that the matched pair DDR chart showed an overall increase, jumping by $5.
