Exact-fit DDR5-4800 RDIMM kit

This 32 GB kit contains two 16 GB DDR5-4800 registered ECC modules rated at CL40 and 1.10 V. The 288-pin RDIMM form factor and 1Rx8 organisation match the memory controller requirements of the GIGABYTE MZ73-LM2 motherboard. Major-brand Samsung, Micron or Hynix chips provide enterprise-grade stability for server workloads.

Servers and workstations needing registered ECC

Suitable for administrators upgrading a GIGABYTE MZ73-LM2 platform that requires registered DDR5 RDIMMs with ECC. Not appropriate for systems that accept only unbuffered UDIMMs or SODIMMs, or for builds that need non-ECC memory. Buyers whose boards demand a different speed, voltage or rank configuration should verify the manual before ordering.

Registered ECC with 1Rx8 organisation

The registered buffer and on-die ECC correct single-bit errors in real time while reducing electrical load on the memory controller. This allows full-capacity population of every supported slot on the MZ73-LM2 at the rated DDR5-4800 data rate. Confirm your motherboard's qualified-vendor list and population rules to ensure the 1Rx8 rank structure is supported.

Questions about this item

Is this a single 32GB module or a kit of two 16GB modules?

The kit contains two 16GB DDR5 RDIMMs for a total of 32GB, giving you dual-channel bandwidth on the GIGABYTE MZ73-LM2 board.

Will the modules run at 4800 MT/s on my GIGABYTE MZ73-LM2 motherboard?

Yes, the kit is rated DDR5-4800 (PC5-38400) and the MZ73-LM2 memory controller supports that speed with 1Rx8 registered ECC DIMMs at 1.1V.

Does the 288-pin RDIMM form factor and registered ECC design match what the MZ73-LM2 requires?

The board needs 288-pin registered ECC RDIMMs; this kit uses exactly that layout with CL40 timing and 1.1V operation.
