  • 64 GB capacity lets your server handle larger workloads
  • DDR5 4800 speed matches the board's rated memory clock
  • Registered ECC design corrects single-bit errors for data integrity
  • 2Rx4 1.1 V CL40 spec aligns with the memory controller's expectations
  • 288-pin RDIMM form factor fits the GIGABYTE MZ73-LM2 motherboard

Exact-match server upgrade

This 64GB DDR5 4800 RDIMM delivers 2Rx4 registered ECC memory at 1.1V with CL40 timing. It is built as a direct replacement for the GIGABYTE MZ73-LM2 motherboard so the memory controller recognises the full capacity at rated speed. The 288-pin registered form factor matches the board's required slot type exactly.

Who this suits

IT teams populating a GIGABYTE MZ73-LM2 with validated registered ECC modules for production workloads will benefit from the spec-matched rank, voltage and timing. Buyers who need unbuffered UDIMMs, SODIMM form factors or non-ECC memory for consumer platforms should look elsewhere.

Installation notes

The module installs in the standard 288-pin DDR5 RDIMM slots following the motherboard manual's population order. Common issues include mixing registered and unbuffered DIMMs, ignoring the approved slot sequence, or exceeding the board's supported capacity per channel. Verify the manual before seating the module.

Questions about this item

Does the GIGABYTE MZ73-LM2 motherboard need a specific BIOS version or CPU to run this 4800 MHz DDR5 RDIMM at its rated speed?

The module is an exact-match upgrade validated for the MZ73-LM2; install it in the correct DIMM slots per the board manual and the memory controller will recognise the 2Rx4 rank, 1.1 V voltage and CL40 timing at 4800 MHz without further configuration.

Can I mix this 2Rx4 registered ECC RDIMM with older unbuffered DDR5 UDIMMs already installed in the server?

No. The MZ73-LM2 requires registered RDIMMs; mixing registered and unbuffered modules is not supported and will prevent the system from posting.

After installation, how do I confirm the kit is operating at 4800 MHz with ECC active?

Enter the BIOS or use a hardware-information utility; it should report 4800 MT/s, CL40, 1.1 V and show ECC enabled for the 64 GB module.
