The number of dual-channel DDR platforms continues to increase, and has really created a subset of the memory market. The "matched pair" format is becoming increasingly 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 the 2x256-MB and 2x512-MB kits, and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
The high-end matched pair DDR price list showed a bit more activity than the single module one, but even so, about half of the listings showed little or no activity. The modules that did receive noticeable price cuts were mostly at the high-end, including nice decreases to Corsair XMS PC4000 2x512-MB and Kingston HyperX PC4300 2x512-MB. The news wasn't all good, as Kingston HyperX PC3700 2x512-MB and Corsair XMS PC2700LL 2x512-MB jumped by $20 and $45 respectively.
