M391A4G43AB1-CVF Samsung 1x32GB DDR4 UDIMM ECC RAM

High-Density DDR4 ECC UDIMM server memory expansion featuring JEDEC-standard reliability with the M391A4G43AB1-CVF

The M391A4G43AB1-CVF is a Samsung 32GB DDR4-2933 ECC Unbuffered UDIMM designed for server platforms that require UDIMM compatibility rather than RDIMM/LRDIMM buffering. In CPU-bound infrastructures such as single-socket edge nodes and density-optimized 1U systems, the M391A4G43AB1-CVF enables practical capacity scaling while preserving a predictable memory timing envelope under mixed virtualization and general-purpose compute workloads.

As a DDR4 288-pin module operating at 1.2V with a JEDEC-standard profile, the M391A4G43AB1-CVF integrates cleanly into enterprise BIOS defaults without XMP/EXPO dependencies. ECC with a 72-bit data path improves data integrity in long-running services, while the dual-rank x8 organization supports balanced bandwidth utilization across memory channels. For platforms where PCIe expansion and NVMe storage are already constrained by form factor, the M391A4G43AB1-CVF provides capacity uplift without changing the server’s I/O topology, aligning well with compact virtualization clusters and edge consolidation designs.

Why Choose the M391A4G43AB1-CVF?

The M391A4G43AB1-CVF is engineered for deployments where UDIMM support is a hard requirement and memory density must increase without altering platform qualification. It delivers a strong density-to-power profile for space-limited nodes, adds ECC protection for enterprise reliability, and scales predictably across matched modules for straightforward expansion planning in branch, lab, and micro-datacenter footprints.

Samsung applies a consistency-first engineering approach focused on signal integrity, long-term component stability, and controlled manufacturing quality, aligning the M391A4G43AB1-CVF with modern data center operational standards and qualification processes.
