UDIMMs for the Right Price/Performance Balance

Our unbuffered DIMMs (UDIMMs) are the ideal module for high-speed, low-cost desktop computer systems for at least three reasons. First, they're fast. Since UDIMMs rely on the motherboard for buffer logic and registers, and since they don’t need those functions on the module, there’s nothing slowing them down. Second, our UDIMMs are parity and ECC-capable, so they can provide as much as 100% data reliability. Third, because our UDIMMs are an industry standard and in high-volume production, they offer a great balance of price and performance.

Design Guide for Two DDR3-1066 UDIMM Systems

Our engineers have assembled their DDR3 expertise into a Design Guide for Two DDR3-1066 UDIMM Systems. It’s full of information about DDR3 module memory topologies, board layout guidelines, and timing budget recommendations, making it an excellent place to start when you’re developing quality DDR3 motherboards that use DDR3-1066 UDIMM systems.

Full JEDEC Compatibility

Detailed, Specific Tech Support for UDIMMs

Our UDIMMs are easy to replace, easy to upgrade, and JEDEC compatible. Regardless of which JEDEC UDIMM specification you design to—DDR2 UDIMM Design Specification 1.0 or DDR3 UDIMM Design Specification 0.81, for example—our parts meet it.

At Micron, we want to provide you with the best technical support in the memory-making business. We offer multistage technical assistance in the form of savvy application and field engineers; reams of technical notes and data sheets; and abundant simulation models, calculators, and development tools. These resources are here so you can design in a Micron UDIMM with ease.


2 Advantages of Designing With Micron UDIMMs
