32GB DDR5 ECC RDIMM for servers

This 32GB DDR5 5600 registered DIMM targets server and workstation administrators who need error-correcting memory for data integrity. The single-rank 1Rx4 organisation keeps electrical loading low on populated channels. It replaces the Hynix HMCG84AGBRA module in compatible platforms. Systems requiring non-ECC or unbuffered memory cannot use this module.

Registered buffer and ECC protect data flow

The registered design places a buffer between the memory controller and the DRAM, reducing signal loading on dense configurations. On-die ECC corrects single-bit errors inside the chip before data reaches the bus. Together they maintain throughput under sustained multi-threaded workloads. No additional software or drivers are required to activate these functions.

288-pin DIMM at standard DDR5 voltage

The module uses the industry-standard 288-pin DDR5 DIMM form factor and operates at 1.10V. Gold-edge contacts resist oxidation during long-term rack deployment. A single 32GB stick allows capacity scaling in one-module increments. Builders needing 262-pin SO-DIMM or desktop UDIMM form factors must select a different product.

Questions about this item

Will the 1.10V DDR5 5600 module need any firmware updates or capacitor replacements over its service life?

No firmware or capacitor maintenance is required; the registered DIMM uses major-brand chips tested to A-Tech quality standards and is covered by a lifetime warranty.

What thermal or signal-integrity limit appears first when the 1Rx4 ECC RDIMM runs at 5600 MT/s continuously?

The registered buffer and on-die ECC maintain signal integrity at CL40, so the practical ceiling is the platform's DDR5 5600 memory-controller spec rather than the module itself.

How much heat and power does the 288-pin 32GB stick draw during all-day server workloads?

At the standard 1.10V DDR5 voltage the module draws only the power needed for 5600 MT/s operation, and the registered design keeps thermals within normal server DIMM limits.
