Rack Up Server Performance with LRDIMMs
Our load-reduced DIMMs (LRDIMMs) use a specially designed buffer to reduce the data load to a single load (up to an 8-rank DIMM), whereas standard RDIMMs present multiple loads for dual-rank and quad-rank versions and limit the amount of data you can load to the data bus. Implementing LRDIMMs enables you to add more DIMMs per channel and increase the memory capacity and speed of your systems.
LRDIMM Part Information and Documentation
We are currently sampling limited quantities of LRDIMMs to select customers. Contact Micron for LRDIMM availability and documentation.
Micron Announces World’s First LRDIMMs
We’re the first to introduce LRDIMMs, the highest density DIMMs available. Because our LRDIMMs are based on our ultra-efficient 2Gb DDR3 components, they offer high density and high performance at a price that makes it feasible to implement in your next server design.
Read our LRDIMM Announcement
Because we build both the DDR3 components and finished modules, we can carefully test our LRDIMMs at each stage of the manufacturing process. But because end quality is dependent on more than just reliability, we’re also working closely with buffer suppliers and server OEMs to ensure that our LRDIMMs function well with multiple server platforms.
LRDIMMs support higher densities than RDIMMs and enable you to add more DIMMs per channel. The result? Triple the available density and as much as a 57% increase in bandwidth. This enables you to get more performance from a single server, boosting overall data center efficiency.
