32GB DDR5 4800 ECC RDIMM

This 32GB DDR5 module runs at 4800MHz with CL40 latency and 1.10V operation. It uses a 288-pin DIMM form factor and features ECC registered (RDIMM) architecture with a 1Rx4 (EC4) rank configuration. The module is built as a compatible replacement for Hynix HMCG84MEBQA, HMCG84MEBQA113N, and HMCG84MEBQA115N part numbers.

Server and workstation memory upgrades

Suited for administrators expanding capacity in DDR5 server or workstation platforms that require registered ECC memory. Not suitable for desktop boards that accept only unbuffered non-ECC DIMMs, nor for systems limited to lower memory speeds or voltages. Buyers who need a different capacity, rank layout, or CAS latency should verify platform requirements before ordering.

1Rx4 registered ECC rank layout

The single-rank 1Rx4 (EC4) organisation determines how the memory controller addresses this module and influences maximum supported capacity per channel. Confirm that the target platform supports this specific rank configuration and registered ECC operation to ensure compatibility.

Questions about this item

Will this 288-pin DDR5 DIMM fit my server's registered memory slots?

The module uses the standard 288-pin DDR5 DIMM form factor and is a registered ECC RDIMM, so it fits server and workstation boards that accept DDR5 RDIMMs.

Do I need to change any BIOS settings when installing this 1Rx4 CL40 module?

Install the DIMM with the system powered off, seat it until the retention clips click, then enable ECC in the BIOS if it is not on by default; the module runs at 1.1 V and CL40 at 4800 MT/s.

How do I know when this 32 GB ECC RDIMM should be replaced?

ECC corrects single-bit errors and logs them; replace the module if the system reports uncorrectable errors, repeated correctable-error thresholds are crossed, or memory diagnostics show persistent failures.
