Today we announced the world’s first DDR3 LRDIMM
s, built with our advanced 50nm, DDR3 SDRAM
components. If you’re in the server industry, you know that load-reduced DIMMs are going to deliver some much-needed performance and bandwidth boosts for next-generation servers. Their much higher capacity and performance specs mean that early LRDIMM servers will have up to 57% better bandwidth and as much as three times the memory density—up to 144GB. And you can expect those specs to rise as mainstream DDR3 production moves from 2Gb components to 4Gb and beyond.
How do they do it? Basically, an eight-rank LRDIMM can reduce memory load to a single load per channel (traditional RDIMM loads correspond to the number of ranks; dual-rank=2 loads, quad-rank=4 loads). Lower loads means you can put more DIMMs on a channel (and/or run the modules faster, depending on the configuration), boosting performance and memory density. LRDIMMs are also capable of much higher densities than RDIMMs; we’re making 16GB LRDIMMs today and plan for higher densities in the future.
We’re currently sampling these to buffer suppliers (to make sure our LRDIMMs are as fast and reliable as possible) and a few select server OEMs. You can probably expect to see ultra-high density, high-performance LRDIMM servers hitting the market before mid-year 2010.
