A-Tech 64GB DDR5 4800 ECC RDIMM 2Rx4 HMCG94MEBRA112N

A 64 GB DDR5 ECC RDIMM for server workloads

This module delivers 64 GB of DDR5 4800 memory with ECC and registered buffering. It is built for servers and workstations that need error correction and signal integrity at scale. The 2Rx4 organisation and 1.1 V operation suit high-density platforms. Buyers who need non-ECC or unbuffered DIMMs should look elsewhere.

Thermals noise and power draw at standard voltage

At the specified 1.1 V the module runs at the DDR5 baseline voltage, keeping power draw predictable in typical server deployments. Registered buffering reduces electrical load on the memory controller, which helps system thermals under normal multi-tasking. No active cooling is required on the DIMM itself. Systems without adequate airflow may still see higher temperatures.

Behaviour under sustained load rather than burst use

The CL40 latency and registered design provide stable throughput during extended compute or virtualization tasks. ECC corrects single-bit errors on the fly, preventing data corruption during long-running workloads. The 2Rx4 layout maintains signal quality across full-capacity configurations. Workloads that demand lower latency or higher frequencies will not be satisfied by this specification.
