Micron 32GB DDR5-4800 RDIMM 1Rx4 ECC Registered

The Micron 32GB DDR5-4800 RDIMM (MTC18F1045S1RC48BA1) is a single-rank, x4 registered ECC memory module engineered for mainstream enterprise servers. Built on Micron's advanced DDR5 silicon, it operates at 4800 MT/s with a 1Rx4 topology that delivers the signal integrity and thermal characteristics required for high-density, multi-socket server deployments. The registered (buffered) design incorporates an on-DIMM register clock driver (RCD) that extends memory channel reach and supports larger memory configurations per channel compared to unbuffered alternatives.

DDR5 architecture introduces on-module power management through an integrated PMIC (Power Management IC), shifting voltage regulation from the motherboard to the DIMM itself and enabling tighter power delivery tolerances. The module operates at 1.1V, a reduction from DDR4's 1.2V, contributing to lower per-module power draw at equivalent or greater bandwidth. DDR5 also doubles the burst length to BL16 and introduces two independent 32-bit subchannels per module, effectively improving memory channel efficiency and error isolation granularity. ECC is implemented natively within each 32-bit subchannel, providing enhanced data integrity over DDR4's single-channel ECC scheme.

This module is positioned as a high-volume workhorse for general-purpose server builds launched from 2023 onward on platforms supporting Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC (Genoa/Bergamo) processors. Its 1Rx4 organization makes it particularly well suited for environments where memory capacity per slot is balanced against maximizing the number of populated channels, such as cloud infrastructure nodes, enterprise virtualization hosts, and database servers requiring reliable throughput at scale.

Ideal for

• General-purpose two-socket server deployments requiring balanced memory capacity and bandwidth across all available DIMM slots
• Enterprise virtualization hosts running VMware vSphere or Microsoft Hyper-V where ECC reliability is mandatory for hypervisor and guest VM memory integrity
• Cloud infrastructure nodes and high-density rack servers where DDR5 power efficiency reduces per-rack thermal load at scale
• Relational and in-memory database servers (Microsoft SQL Server, Oracle Database) that benefit from ECC-protected, high-throughput memory subsystems
• Enterprise HPC and technical computing clusters where registered DIMMs enable large, stable memory configurations across multi-socket nodes
• Software-defined storage platforms and NVMe-oF targets requiring reliable memory for caching layers and metadata operations
