Exact-match server upgrade

This NEMIX RAM kit delivers 512GB of DDR5 memory across four 128GB registered DIMMs. It is built for the GIGABYTE MZ23-SU0 motherboard and meets the board's required rank, voltage and timing so the memory controller recognises the full capacity at the rated 6400 speed.

Registered ECC stability

Each module uses a 288-pin RDIMM form factor with a 2Rx4 organisation and operates at 1.1V. The registered architecture buffers the command bus to keep every slot stable when fully populated, while on-die ECC corrects single-bit errors before they affect production workloads.

DDR5-6400 platform limits

The kit runs at PC5-51200 with a CL52 latency, matching the motherboard's validated memory profile. Population rules and maximum supported capacity are defined by the system firmware, so the manual must be consulted before installation to confirm the approved DIMM order and any BIOS requirements.

Questions about this item

What speed does the DDR5 6400 interface run at on the GIGABYTE MZ23-SU0?

The kit operates at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V, matching the board's rated memory speed when all four slots are populated.

What physical slot and form factor do these modules need on the MZ23-SU0?

Each 128 GB module is a 288-pin DDR5 RDIMM; the board requires registered DIMMs, not UDIMM or SODIMM, and all four DIMM slots must be filled for the full 512 GB capacity.

How should the four RDIMMs be installed, and what step is often missed?

Follow the motherboard manual's exact population order for four 2Rx4 registered DIMMs; the common mistake is inserting them in the wrong slot sequence, which prevents the system from recognizing the full 512 GB at 6400 MT/s.
