Server Memory Module

This A-Tech 32GB DDR5 4800 ECC RDIMM is a registered server memory module built for enterprise workloads. It operates at 1.1V with a CAS latency of CL40 and uses a 1Rx4 (EC8) organisation. The module is designed as a compatible replacement for the Hynix HMCG84MEBRA115N part number.

Workstations needing registered ECC

It suits administrators upgrading or repairing servers and workstations that require registered ECC DDR5 memory at the 4800 MT/s speed grade. Builders whose platforms only accept unbuffered UDIMMs or non-ECC modules should look elsewhere, as this stick will not function in those systems.

Registered ECC with 1Rx4 layout

The defining specification is the registered ECC design combined with a single-rank 1Rx4 chip configuration. This registration and rank structure must match the motherboard's memory controller requirements for the module to be recognised and stable.

Questions about this item

Should I choose this 32 GB DDR5 4800 ECC RDIMM or a different capacity for my server upgrade?

This module provides a single 32 GB stick at DDR5 4800 with CL40 latency and 1.10 V operation. Match the total capacity to your motherboard's maximum supported memory and available DIMM slots.

What does the DDR5 4800 rating mean for actual throughput in my workstation?

The 4800 MT/s data rate sets the maximum clock speed the memory can run at; real-world bandwidth depends on your CPU's memory controller, channel configuration and BIOS settings.

Is the 288-pin DDR5 RDIMM interface compatible with standard server motherboards and what limits apply?

The module uses the 288-pin DDR5 DIMM form factor with registered ECC signalling. It fits DDR5 RDIMM slots; the platform's memory controller determines the maximum supported speed and rank population rules.
