Samsung 32GB DDR5 5600MHz PC5-44800 ECC RDIMM Memory Module

The Samsung M321R4GA0PB0-CWM is a 32 GB DDR5 ECC registered memory module designed for modern servers that need fast, reliable system memory. Running at 5600 MHz under the PC5-44800 specification, it helps multi-core processors keep data moving quickly and consistently, which is essential for virtualization, large databases, and high-traffic web or application servers.

This DIMM follows the JEDEC DDR5 standard and operates at just 1.1 V, so it balances performance with power efficiency. The onboard register steadies clock, command, and control signals, and the built-in 8-bit error-correcting code continuously checks and corrects data in flight. That combination keeps mission-critical workloads stable, even during heavy parallel processing or sustained peak demand.

The module uses a 1Rx4 single-rank layout, making it a solid option for servers that accept up to two DIMMs per channel. System administrators who want to expand memory capacity without replacing existing hardware can install these modules alongside other compatible DDR5 RDIMMs, provided the server’s firmware supports 5600 MHz speeds.

Because it uses a registered architecture and ECC, this module will work only in servers qualified for DDR5 RDIMM memory. It will not function in desktop PCs, workstations that require UDIMMs, or any laptop. Always confirm compatibility with the server’s motherboard or the manufacturer’s qualified vendor list before purchase.
