SKU CH-A329-RYJ5F

32 GB DDR4 server memory with ECC and registered operation at 2666 MHz CL19 1.2 V 288-pin

  • 32 GB capacity handles heavy server workloads
  • ECC registered design protects data integrity
  • DDR4 2666 MHz CL19 delivers responsive throughput
  • Low 1.2 V operation reduces power draw

Server-grade DDR4 module

The SK hynix HMA84GR7AFR4N-VK is a 32 GB DDR4 registered DIMM with ECC and dual-rank x4 organisation. It runs at 2666 MHz with a CAS latency of 19 and operates at 1.2 V across 288 pins. This module targets servers and workstations that require error correction and registered buffering for stability.

Thermals and power profile

Standard DDR4 voltage of 1.2 V keeps power draw low during typical workloads. Registered buffering reduces electrical load on the memory controller, helping maintain consistent thermals. Passive cooling in a chassis with adequate airflow is sufficient for normal operation. No active cooling or special power requirements are needed.

Questions about this item

How do I install this 288-pin DDR4 module and what step do people often get wrong?

Align the notch on the module with the slot key, press down firmly until both retention clips click, and ensure the system is fully powered off and unplugged — the common mistake is seating it on standby power.

What maintenance or replacement will this 32GB ECC Registered CL19 2666MHz module need later?

No scheduled maintenance is required; if a correctable error count rises or the system logs uncorrectable ECC events, replace the module — otherwise it runs for the server's service life.
