The number of dual-channel DDR platforms continues to increase, and has really created a different section 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 currently the 2x512-MB and 2x1-GB kits, and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
News was even worse in the matched pair DDR listings, and instead of an aggregate chart drop, we're seeing overall prices rise by $14. This may not seem like much, but when you're used to overall chart prices dropping by triple-digits, any price increase is too much. There were three price cuts that hit double digits, as Mushkin eXtreme PC4000 2x1-GB fell by $17, Mushkin eXtreme PC4000LL 2x1-GB dropped $16, and gigaram Mach 1000 PC3500 2x1-GB received a $15 price cut. Of course, there were a couple of significant price increases to account for, the largest of which was a $35 jump to Corsair XMS PC3200LL 2x512-MB. This is a very tough week for DDR buyers overall, and we'll have to see if the trends stay constant with our Registered DDR and DDR2 listings.
