  • 384 GB total capacity from six 64 GB modules for maximum server memory density
  • DDR5 4800 speed with CL40 latency delivers rated bandwidth for the GIGABYTE MZ73-LM2
  • Registered ECC design with 2Rx4 organisation corrects single-bit errors and supports full-slot population
  • 1 V operating voltage matches the platform specification for stable low-power operation
  • 288-pin RDIMM form factor ensures exact mechanical and electrical fit in the target motherboard

Exact-Match DDR5 Server Upgrade

This 384GB kit delivers six 64GB DDR5 4800 RDIMM modules built to the precise rank, voltage and timing the GIGABYTE MZ73-LM2 motherboard expects. Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly, keeping fully populated slots stable at rated speed.

Verified Fitment for MZ73-LM2

The 288-pin Registered form factor matches the board's DDR5 4800 PC5-38400 requirement, avoiding the UDIMM or SODIMM mismatch that prevents boot. Population rules and maximum supported capacity vary by BIOS revision, so the system or motherboard manual must be consulted before installation.

Suited for Capacity-Critical Servers

Administrators who need the full 384GB at DDR5 4800 with ECC integrity will find this kit validated for the target platform. Builders requiring higher frequencies, lower latencies, non-ECC modules or a different DIMM type should look elsewhere.

Questions about this item

Will the 288-pin RDIMM modules fit the DIMM slots on the GIGABYTE MZ73-LM2 motherboard?

Yes, the 288-pin RDIMM form factor matches the slots required by the GIGABYTE MZ73-LM2 motherboard. The kit is spec-matched to the board's memory population rules for proper fitment.

What is the correct installation order for the six 64GB modules on the GIGABYTE MZ73-LM2?

Install the six 2Rx4 modules following the motherboard manual's approved DIMM population sequence. Server boards often require specific slot filling per channel for full 384GB recognition at DDR5-4800.

Do the Samsung, Micron, or Hynix chips on these modules require active cooling or replacement over time?

The modules have no heat spreader and rely on chassis airflow. The ECC Registered design corrects single-bit errors on the fly. No chip replacement is expected under normal server operation.
