  • 64 GB capacity lets the GIGABYTE MZ33-AR1 reach its maximum supported memory
  • DDR5 5600 speed matches the board's rated frequency for full throughput
  • Registered ECC design offloads the controller and corrects single-bit errors for enterprise stability
  • 2Rx4 dual-rank organisation fits the motherboard's population rules without manual tuning
  • 1 V operation keeps power draw low while meeting the server's voltage spec

Exact-match server upgrade

This 64 GB DDR5 5600 registered ECC RDIMM is built for administrators expanding a GIGABYTE MZ33-AR1 system. The 2Rx4 organisation, 1.10 V operating voltage and CL46 timing match the board's memory-controller expectations so every slot can run fully populated at rated speed. Enterprise workloads benefit from the registered buffer that offloads the controller and on-die ECC that corrects single-bit errors before they reach production data.

Check board population rules

Verify the motherboard manual for supported capacities per slot, approved DIMM population order and any BIOS revision requirements before ordering. The module uses the 288-pin RDIMM form factor required by this platform; UDIMM or SODIMM variants will not fit or function. Confirm that your chassis airflow can accommodate the bare-module design which has no integrated heat spreader.

Thermals noise and power

Registered architecture and the low 1.10 V voltage keep per-module power draw modest under typical server loads. With no heat spreader or active cooling on the DIMM itself, temperatures depend entirely on case airflow directed across the memory slots. Acoustic output is silent as there are no moving parts on the module.

Questions about this item

Does the package contain a single 64GB DDR5 5600 CL46 2Rx4 1.1V ECC Registered 288-pin RDIMM or a kit of multiple modules?

The package content lists a 64GB DDR5 5600MHz PC5-44800 2Rx4 1.1V 288-PIN ECC RDIMM kit, which is a single 64GB registered DIMM ready to install.

How do I choose between different capacities or speeds for the GIGABYTE MZ33-AR1 motherboard?

This module is an exact-match upgrade at 64GB, DDR5 5600, CL46, 2Rx4, 1.1V registered ECC — the precise rank, voltage and timing the MZ33-AR1 memory controller expects for full-capacity recognition.

What does the DDR5 5600 PC5-44800 rating mean once the RDIMM is installed in the server?

It runs at 5600 MT/s with CL46 latency at 1.1V; the registered buffer offloads the memory controller so every populated slot operates at the rated speed while ECC corrects single-bit errors on the fly.
