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 memory listings continued the trends we found in the DDR charts, and contained a nice set of price drops to go with very limited price increases. The price cuts that reached double digits included Crucial Ballistix DDR2-667 1-GB (-$19), Kingston HyperX DDR2-1000 1-GB (-$18), and WINTEC AMPX DDR2-1000 1-GB (-$10), while the largest price spike was a nominal $3 increase to the cost of PQI Turbo DDR2-800 1-GB. This placed overall single-module DDR2 listings movement directly in the consumer's favor, with a total chart drop of $67 this week. It will be interesting to see if matched pair DDR2 continues this trend, or moves in the other direction.
