Exact DDR5-4800 RDIMM Upgrade

This 64GB DDR5 module runs at 4800MHz PC5-38400 with CL40 latency and 1.10V operation. It uses a 2Rx4 registered ECC design on a 288-pin form factor built with major OEM chips. The specification matches the GIGABYTE MZ23-SU0 motherboard requirements for full-capacity recognition and rated-speed operation.

Replaces Mismatched or Lower-Capacity DIMMs

When a server currently runs slower DDR5 speeds, non-ECC unbuffered memory, or partial population that limits total capacity, this kit restores the registered architecture the memory controller expects. The jump is worth it when the workload demands error correction and full-slot stability at the board's native 4800MHz data rate.

Suits GIGABYTE MZ23-SU0 Server Builds

This module fits administrators populating the MZ23-SU0 with validated registered ECC DIMMs for production stability. Builders needing unbuffered UDIMMs, SODIMM form factors, or speeds beyond the DDR5-4800 specification should look at something else.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the GIGABYTE MZ23-SU0 motherboard slots?

Yes, the 288-pin RDIMM form factor matches the slots on the GIGABYTE MZ23-SU0; it is not a UDIMM or SODIMM and the registered design is what the board requires.

What is the correct order to populate the DIMM slots when installing this registered ECC module?

The motherboard manual defines the approved population sequence; follow that order exactly so the memory controller recognises the 2Rx4 rank layout and runs at the rated 4800 speed.

Does this module have a heat spreader that could need cleaning or replacement over time?

No heat spreader is fitted, so there is no spreader to clean or replace; the bare PCB operates at the specified 1.10 V within normal server airflow.
