Server memory upgrade

This NEMIX RAM kit provides 128GB of DDR5 ECC Registered RDIMM memory built to the exact electrical and mechanical specification of the GIGABYTE MZ73-LM1 motherboard. It targets administrators upgrading or repairing that specific server platform where registered DIMMs are mandatory.

Registered ECC 2Rx4 CL52

The modules run at DDR5 6400 (PC5-51200) with a CAS latency of CL52, 1.10V operation and a 2Rx4 organisation. Registered buffering and on-die ECC allow full population of every slot at rated speed while correcting single-bit errors before they reach the operating system.

Single-module 128GB kit

The package contains one 288-pin RDIMM delivering the full 128GB capacity in a single stick, leaving remaining slots free for future expansion. No heat spreader is fitted, so the module relies on the server chassis airflow for cooling.

Questions about this item

What does the 6400 MT/s rating mean once this module is installed in the GIGABYTE MZ73-LM1?

The board's memory controller will run the kit at DDR5-6400 with CL52 timings at 1.10 V, delivering the rated PC5-51200 bandwidth when populated according to the manual.

How does the 288-pin RDIMM interface affect what the system can actually use?

The registered 288-pin form factor is required by the MZ73-LM1; it enables full-capacity operation across all supported slots and provides ECC error correction that UDIMMs cannot.

What physical clearance and slot requirements does this 128 GB RDIMM need?

It fits a standard 288-pin DDR5 RDIMM slot with no heat spreader, so only the motherboard's DIMM spacing and population order from the manual apply.
