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 greater fluctuations than the single module chart, and the overall cuts ran much deeper. This is only logical given the doubling effect of matched pair kits, and instead of simply double-digit cuts, there were some real doozies in this area. Ultra high-end DDR was hit the hardest, with Corsair XMS PC4400 PT 2x512-MB dropping $47 and Kingston HyperX PC4300 2x256-MB falling by $17. This area was also volatile in the opposite direction and there were many price spikes to contend with. Mushkin PC3200 L1 2x512-MB (+$52), OCZ PC4200 EL 2x512-MB (+$31) and Kingston HyperX PC3700 2x512-MB (+$30) showed the largest increases this week. As in our previous guide, it's another tough week in the dual-channel DDR kit market, but those who look closely can still find the deals.
