SK hynix 32GB DDR4-2666 ECC Registered RDIMM Server Memory (HMA84GR7CJR4N-VK) – 2Rx4

OEM ECC memory for expanding DDR4 servers and workstations.

The SK hynix HMA84GR7CJR4N-VK is a 32GB DDR4-2666 ECC Registered DIMM for servers and workstations. It suits data center teams and homelab builders expanding Intel Xeon Scalable or AMD EPYC systems with OEM-grade memory for virtualization, databases, and storage servers.

Why ECC Registered Memory Keeps Servers Stable

Servers hold large amounts of active data in RAM for long periods. ECC detects and corrects single-bit errors on every access, preventing silent corruption and unplanned crashes.

Registered DIMMs place a register between the memory controller and the DRAM, buffering command and address signals. This reduces electrical load so servers can run more DIMMs per channel reliably.

This module is a dual-rank x4 design at 2666 MT/s and 1.2V, matching many servers built on first- and second-generation Xeon Scalable processors.

Room for More Virtual Machines

At 32GB per slot, servers with 16 to 24 slots reach 512GB to 768GB, supporting dense virtualization and large database caches.

OEM Memory for Mixed-Brand Fleets

SK hynix supplies memory to major server OEMs, so this module type is widely used across Dell, HPE, Lenovo, and Supermicro platforms.

How to Install SK hynix RDIMM Server Memory

1. Shut down the server, remove power cords, and use an anti-static strap.
2. Consult the server’s DIMM population guide to choose the correct slots for balanced channels.
3. Insert the RDIMM with the notch aligned and press until the ejector tabs lock.
4. Power on, allow memory training, and confirm capacity and ECC status in BIOS or the management controller.
