8GB DDR4 2933MHz ECC RDIMM for Servers

This 8GB registered DIMM runs at DDR4 2933MHz (PC4-23400) with CL21 latency and 1.20V operation. It uses a 1Rx8 organisation and major-brand chips to deliver error-correcting memory for server and workstation platforms.

Verify DDR4 RDIMM support and 288-pin slots

Confirm that your system accepts DDR4 registered ECC modules in a 288-pin DIMM form factor before ordering. The module is a direct replacement for Hynix HMA81GR7CJR8N-WM and HMA81GR7DJR8N-WM part numbers.

Steady 1.20V draw under continuous workloads

Registered buffering and on-die ECC maintain signal integrity during sustained multi-threaded tasks. The single-rank layout keeps electrical loading predictable for stable long-duration operation.
