SK hynix HMCG88MEBRA – 32GB DDR5-4800 ECC Registered Server Memory
SK hynix HMCG88MEBRA is a 32GB DDR5-4800 ECC Registered DIMM (RDIMM) designed for enterprise servers and professional workstation platforms. Featuring 2Rx8 dual-rank architecture, 288-pin interface, 1.1V operating voltage, and CL40 latency, this module delivers reliable memory performance, high bandwidth, and ECC-based data integrity for demanding server workloads.
Description
The SK hynix HMCG88MEBRA is a high-performance 32GB DDR5 SDRAM Registered DIMM engineered for modern server and workstation environments requiring dependable memory capacity, bandwidth, and error protection.
Operating at 4800 MT/s, the module provides a theoretical peak bandwidth of approximately 38.4 GB/s per module and conforms to the PC5-38400 memory speed classification. Its 2Rx8 dual-rank organization provides the memory architecture expected by compatible enterprise server platforms, while the Registered/Buffered design helps improve signal integrity and scalability in systems using multiple DIMMs.
The module operates at 1.1V and is specified with CL40 latency, offering a balanced combination of performance and power efficiency for DDR5-based server platforms. The 288-pin RDIMM form factor is intended for systems specifically designed to accept DDR5 ECC Registered memory and should not be substituted for consumer DDR5 UDIMM or DDR5 SODIMM modules.
ECC functionality helps detect and correct certain memory errors, making the HMCG88MEBRA suitable for infrastructure where system stability and data integrity are important. Typical applications include virtualization, enterprise applications, databases, cloud infrastructure, professional workloads, and general-purpose server deployments.
