M393A4K40EB3-CWECO

• 32 GB DDR4 RDIMM (registered DIMM) for Server Platforms
• 3200 MT/S Data rate, 3200 MHz Clock speed, 1600 MHz Base Clock
• 2Rx4 Dual-Rank organization; (2G X 4) X 36 Component Composition
• Samsung E-die; 288-Pin module; 1.2 V Operating Voltage
• Registered Address/Command Buffering for Higher DIMMs-per-Channel Capacity

The M393A4K40EB3-CWECO is a Samsung 32 GB DDR4 registered DIMM (RDIMM) rated at 3200 MT/s with a 1600 MHz base clock, built on Samsung E-die. It is a 2Rx4 dual-rank module using a (2G x 4) x 36 component composition on a 288-pin form factor, operating at 1.2 V. The register on an RDIMM buffers address and command signals, which is what allows servers to populate more DIMMs per channel than unbuffered memory permits. The M393A4K40EB3-CWECO is a standard server memory module intended for platforms that specify DDR4-3200 RDIMM.

DDR4-3200 RDIMMs are the standard main memory for the last generation of two-socket and four-socket enterprise servers, and 32 GB is the most common capacity point for balancing cost per gigabyte against DIMM slot count. A 2Rx4 module like the M393A4K40EB3-CWECO delivers better rank interleaving than a single-rank part, which helps bandwidth-sensitive workloads such as virtualization, in-memory databases, HPC and analytics. Because DDR4 platforms remain in wide production and support, these modules are bought both for new server builds and for capacity expansion and RMA replacement in installed fleets. Typical buyers are server OEMs and ODMs, systems integrators, hosting and cloud providers, and enterprise IT teams.
