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 DDR2 memory charts have been extremely volatile over the past few weeks, with unprecedented price increases washing over this section with reckless abandon. Our last guide charted a total chart increase of $331 for single-module DDR2, but things have since cooled down and this time the aggregate jump was only $22. There was still a lot of individual pricing activity on both side, with six price drops and eight price increases that reached double digits. Some of these were quite large, and Crucial Ballistix DDR2-800 1-GB fell by $65, while Crucial Ballistix DDR2-1000 1-GB received a healthy $60 price drop. It's the same deal on the price increase end of the chart, as the OCZ DDR2-667 Gold 1-GB and OCZ DDR2-900 Platinum 1-GB modules jumped by $50 and $60, respectively.
