96GB DDR5 4800 ECC RDIMM for servers

This 96GB DDR5 4800 CL40 module is a registered ECC RDIMM built for server and workstation platforms that require error-correcting memory. It operates at 1.1V with a 2Rx4 organisation and fits 288-pin DDR5 slots. The part is validated for Hynix-compatible systems and carries the MR38400-9624K1 designation.

Replaces lower-capacity or non-ECC DDR5 RDIMMs

The jump is worth it when your workload needs 96GB in a single slot and mandatory error correction for data integrity. Registered buffering reduces electrical load on the memory controller, allowing higher total system capacity than unbuffered alternatives. CL40 latency at 4800MT/s matches the standard JEDEC timing for this speed grade.

Verify DDR5 RDIMM support and voltage compatibility

Confirm the motherboard accepts 288-pin DDR5 registered DIMMs and can supply 1.1V operation. Check the qualified vendor list for 96GB 2Rx4 modules and ensure the BIOS revision supports this density. Systems limited to UDIMM or lower maximum capacity per slot cannot use this module.

Questions about this item

Does the 288-pin DDR5 RDIMM fit my Hynix-compatible server motherboard?

Yes, the module is a 288-pin DDR5 RDIMM designed for Hynix-compatible server and workstation boards.

What is the correct way to seat this 2Rx4 registered module so the ECC function initialises?

Power off the system, align the notch with the slot key, press firmly until both retention clips click, then enable ECC in the BIOS.

When should I plan to swap out this 96GB 1.1 V module?

Replace it if the server logs uncorrectable ECC errors or if a memory diagnostic reports persistent faults.
