DDR has been transformed into DDR2 through the doubling of internal data bus, thereby allowing next-generation memory speeds of 533/667/800/1000 MHz and above, and Intel was the first to jump on the DDR2 bandwagon, with the 975X, 955X, 945X, 925X/XE and 915P/G platforms all utilizing this high-end memory. With the release of the AM2 platform, AMD has also joined the DDR2 camp, and this will slowly transform DDR2 into the new memory standard. The DDR2 market continues to expand, with more of the larger vendors jumping on board, we expect capacities and speeds to only increase. As far as the pricing chart goes, this chart looks specifically at single module DDR2, and keeps to the standard DDR2-533, -667, -800, and -1000 speeds, as well as module sizes from 512-MB to 1-GB.
The single module DDR2 chart isn't looking much better and the usual selection of price drops are simply not in evidence. The aggregate change amounted to a $44 increase, and while not that bad by itself, it occurred an area where prices automatically drop each week. There was only a single price drop of any kind, as Corsair XMS2 DDR2-800 1-GB fell by $9, but there was more activity at the other end of the chart, where three double-digit price increases helped make it a tough week for DDR2 buyers. Patriot eXtreme DDR2-800 1-GB (+$15), Crucial Ballistix DDR2-1000 512-MB (+$14), and Crucial Ballistix DDR2-800 512-MB (+$11) were the culprits in this case.
