64GB DDR5 4800 ECC RDIMM

This NEMIX RAM module provides 64GB of DDR5 4800 registered ECC memory in a single 288-pin DIMM. It operates at 1.1V with CL40 latency and uses a 2Rx4 organisation built from major OEM DRAM. The module is validated for Supermicro platforms including the SuperServer SSG-521E-E1CR24H, SSG-521E-E1CR24L and X13SEDW-F motherboards.

Suited for Supermicro server upgrades only

This memory fits administrators expanding capacity in the listed Supermicro SuperServer and workstation models that accept DDR5 RDIMMs. It is not suitable for desktop motherboards, laptops or any system that requires unbuffered non-ECC modules or a different DDR generation.

Simple DIMM installation with manual reference

Installation follows standard server DIMM procedure: power down, open the chassis, align the keyed 288-pin edge connector and press until the retention clips engage. The most common issue is mixing registered ECC RDIMMs with unbuffered DIMMs or populating slots in an order the system board manual does not support, which prevents the server from posting.

Questions about this item

Does my Supermicro SSG-521E-E1CR24H motherboard need a specific BIOS version to run this DDR5 4800 CL40 RDIMM?

The module follows the DDR5 4800 PC5-38400 JEDEC standard, so any BIOS that supports that speed on the SSG-521E-E1CR24H will recognise it automatically.

Can I mix this 2Rx4 1.1V registered ECC module with existing 1Rx8 DDR5 RDIMMs in the same server?

Mixing ranks is possible on many Supermicro platforms, but the memory controller will run all channels at the lowest common speed and latency; check your board's population rules first.

How do I confirm the module is operating at DDR5 4800 with ECC active after installation?

Boot into the BIOS or UEFI and verify the memory speed shows 4800 MT/s, the voltage reads 1.10 V, and ECC status reports enabled or active.
