Micron DDR5 Server DRAM nearly doubles the performance of DDR4

Increase server and workstation performance by 85% or more with DDR5 Server Memory1. DDR5 technology relieves the bandwidth-per-core memory crunch to pull peak computing performance and runs more virtual machines, increasing the responsiveness of virtualized applications. DDR5 is expected to overtake DDR4 global memory shipments during the next few years5, marking a fast transition between the two technologies.

Get more out of DDR5 servers with Micron Server Memory

Micron builds DDR5 server memory with power management integrated circuits (PMICs) on the module, which means you are not paying for power management for the entire system6. This can initially mean a lower overall cost to power DDR5 servers versus DDR4 when some system slots are left open. Micron Server Memory is high quality and is typically less expensive than OEM server memory.

High-performance memory for a new era of data centers

Micron DDR5 Server Memory delivers higher bandwidths along with improved reliability, availability, and scaling, when compared to DDR4. It’s 100% component and module tested to mission-critical server standards and optimized for the next-generation Intel® and AMD® DDR5 server and workstation platforms. As one of three major memory manufacturers, Micron tests and validates our DDR5 server memory to work with all major DDR5 server platforms.

1Under memory-intensive workloads, DDR5 is designed to deliver 1.87x the bandwidth as a result of double burst length, double the banks and bank groups, and significantly higher speed than DDR4, as established by JEDEC, an independent organization that develops open standards for the microelectronics industry.
2DDR5 launch data rate of 4800MT/s transfers 1.5x (50%) more data than the maximum standard DDR4 data rate of 3200MT/s. JEDEC projected speeds of 8800MT/s are 2.75x faster than DDR4’s maximum standard data rate of 3200MT/s.
3Initial DDR5 Server DRAM shipments will not include the VLP RDIMM variation. It will come later in the year.
4Initial shipments will be at 4800MT/s with higher speeds expected to reach at least 6400MT/s in the future.
