Micron unveils 256GB DDR5-8800 memory modules: Revolutionary capacity and performance for the next generation of computing

Micron has unveiled 256GB MCRDIMM memory modules designed for next-generation servers at the Nvidia GPU Technology Conference (GTC), reports TomsHardware. These modules offer a significantly higher capacity and performance boost and are ideal for applications such as AI and big data that need to process large amounts of data efficiently.

The new modules are based on monolithic 32 Gb DDR5 ICs and offer a clock rate of 8800 MT/s. Micron offers both “high” modules with 80 DRAM chips on both sides and standard modules with stacked 2Hi packages for 1U servers. Both modules consume about 20 W, which is remarkably energy efficient compared to previous generations. MCRDIMMs (Multiplexer Combined Ranks) are a special type of dual-rank memory module that doubles performance by accessing both ranks simultaneously. This is made possible by a special buffer that makes the two ranks appear as separate modules and thus enables parallel access to 128 bytes of data per clock.

Micron is probably positioning the new 256 GB MCRDIMMs for AI servers based on Intel’s Xeon Scalable “Granite Rapids” processors. These servers require large memory capacities for training AI models, and Micron’s new modules provide just that. With 256GB MCRDIMMs, a Granite Rapids server can reach up to 3TB of DDR5 memory with 12 slots or 6TB of DRAM with 24 slots. The launch of Micron’s 256GB MCRDIMMs is an important step in the development of next-generation servers. These modules offer unprecedented capacity and performance and will open the door to new possibilities in areas such as AI, big data and high-performance computing.

Other important points:

• Micron introduces 256 GB MCRDIMM memory modules with 8800 MT/s.
• The modules are based on monolithic 32 GB DDR5 ICs and are available in “high” and standard formats.
• MCRDIMMs double the performance through simultaneous access to both ranks.
• Micron is probably targeting AI servers with Intel’s “Granite Rapids” processors with the new modules.
• The 256 GB MCRDIMMs enable a memory capacity of up to 3 TB per 12 slots.

This is an exciting development for the server industry and we look forward to seeing how Micron’s new modules will impact the next generation of servers.
