Server DDR4-3200 registered ECC module

This 64 GB DDR4-3200 registered ECC DIMM is built for servers and workstations that require error-correcting memory. It operates at the standard 1.20 V DDR4 voltage and uses a 288-pin form factor. The module is a direct replacement for Hynix HMAA8GR7AJR4N-XN, HMAA8GR7CJR4N-XN and HMAA8GR7MJR4N-XN parts.

Thermals and power at DDR4 standard voltage

Running at 1.20 V keeps power draw low and heat output modest in typical server workloads. Registered buffering reduces electrical load on the memory controller, helping maintain stable temperatures. No active cooling is required beyond normal chassis airflow.

Sustained load behaviour with 2Rx4 organisation

The dual-rank 2Rx4 layout allows the memory controller to interleave accesses, sustaining throughput during long compute or virtualisation tasks. ECC correction runs continuously without halting the pipeline. CL22 latency remains consistent across extended operations.

Questions sur cet article

How do I install this 288-pin DDR4 RDIMM, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the module is fully seated; the step often missed is confirming both clips have engaged on a registered DIMM.

What maintenance or replacement will this 64GB ECC RDIMM need later?

No routine maintenance is required; replacement is only necessary if a memory error occurs or capacity needs increase, and the module is covered by a lifetime warranty.

What limit appears first under sustained load with this CL22 1.2V module?

The CAS latency of 22 cycles at 3200 MHz sets the timing boundary, while the 1.2 V standard voltage defines the thermal envelope during continuous operation.
