Micron DDR2 — Beyond Fast
If you’re looking for ways to maximize performance, you should know that with Micron memory, you can get as much performance as you need. We’ve set the pace for high-end DDR2 memory, with speeds that top DDR2-1066. We’re also bolstering our DDR2 product line and maximizing our road map so you can get the DDR2 solution you want for the time frame you need it. We’re doing all we can to help you get the very most out of your designs with this high-performance technology. And that goes for overclocking enthusiasts too—who will appreciate being able to tweak it, crank it up, and run it for all it’s worth.
And you probably know that we offer RoHS 6/6-compliant DDR2 parts and that we’re committed to engineering green products. But did you know that we also maintain a full set of products that are 5/6 compliant for industries that have exempt applications? Bottom line—we're committed to you, our customer, and to providing the solutions you need when you need them.

Our DDR2-1066 memory leads the industry with the fastest speeds for component and module devices. At 1066 Mb/s, these devices easily meet industry demand for increased speeds and improved bandwidth—and they do it without requiring any system redesign.
Maximize your energy savings at the microchip level by using energy-efficient Aspen Memory FBDIMMs. Other than the voltage change, using these 1.5V DDR2 FBDIMMs is transparent to your system. The performance, timing, and other operating requirements for 1.5V FBDIMMs are identical to 1.8V FBDIMMs; the 1.5V parts just consume considerably less power.
