64GB DDR5 4800 ECC RDIMM for Servers

This 64GB DDR5 4800 ECC RDIMM module is built for server and workstation platforms that require registered memory with error correction. It uses a 2Rx4 organisation and operates at the standard 1.10V DDR5 voltage. The module is a compatible replacement for Hynix HMCG94MEBRA127N and related part numbers.

Thermals and Power at Standard Speed

Running at 4800 MT/s with CAS latency 40, the module draws 1.10V and has no heat spreader, relying on system airflow for cooling. Registered buffering reduces electrical load on the memory controller, which helps keep power draw predictable during normal multi-tasking workloads.

Behaviour Under Sustained Load

Under continuous heavy workloads the registered design and on-die ECC maintain data integrity without adding latency beyond the rated CAS 40 timing. The major-brand DRAM ICs are tested for stability at the full 4800 MT/s rate, so performance remains consistent during extended compute or virtualisation tasks.

Domande su questo articolo

How do I install this 288-Pin DDR5 RDIMM and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click, and verify the motherboard sees the full 64 GB at 4800 MHz in BIOS.

What maintenance or replacement will this ECC RDIMM need over time?

No scheduled maintenance is required; the module is tested for lifetime reliability and should only be replaced if memory diagnostics report correctable or uncorrectable errors.

What limit appears first when this 1.10 V 2Rx4 module runs sustained workloads?

The CAS latency of 40 and the 4800 MT/s data rate set the throughput ceiling before voltage or thermal limits are reached.
