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 overall activity in the dual-channel DDR chart was far more significant than anything in the single-module DDR chart. For starters, an amazing twelve listings posted double-digit price cuts, with many cutting extremely deep. A $63 drop to OCZ PC3200 Platinum XTC 2x1-GB was by far the largest, but $32 off OCZ PC3200 Platinum 2x1-GB and a $20 cut to Mushkin HiPerformance PC3200 2x1-GB were nothing to sneeze at. There was only a single price increase, as Mushkin eXtreme PC4000LL 2x1-GB jumped by $3. The overall chart trends showed a $224 aggregate drop, which is the best performance we've seen in this chart in quite some time.
