64GB DDR5-4800 Registered ECC RDIMM

This NEMIX RAM module delivers 64GB of DDR5-4800 memory in a 288-pin registered form factor. It operates at 1.10V with CL40 latency and 2Rx4 organisation. The registered design and on-die ECC provide the signal integrity and error correction required by the GIGABYTE MZ73-LM1 motherboard.

Sustained enterprise workloads

Registered buffering reduces electrical load on the memory controller, allowing every populated slot to run at the rated 4800 MT/s continuously. ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs or virtualisation tasks. The 1.10V operation keeps power draw predictable under full population.

Replaces slower or smaller DDR5 RDIMMs

Upgrading from lower-capacity or lower-speed registered DDR5 modules is worthwhile when the platform supports the full 64GB per slot at 4800 MT/s. The jump is not justified for systems limited to UDIMM or SODIMM form factors, or for boards that cannot address this density or rank configuration.

Questions about this item

How much power does a single 64 GB DDR5 4800 module draw at its rated 1.10 V?

Each stick operates at 1.10 V, the standard DDR5 voltage, so power draw scales with the 4800 MT/s data rate and CL40 timing rather than any elevated voltage.

What motherboard slot and memory type are required for this 288-pin RDIMM to be recognised?

The module needs a DDR5 RDIMM slot on a GIGABYTE MZ73-LM1 motherboard; UDIMM or SODIMM slots will not accept the 288-pin registered form factor.

Can I mix this 2Rx4 Registered ECC stick with older unbuffered non-ECC DDR5 DIMMs in the same server?

No — registered ECC and unbuffered non-ECC architectures cannot share a memory channel, so the system would fail to train or disable the mismatched slots.
