  • 256 GB total capacity from two 128 GB modules enables dense memory configurations
  • DDR5 5600 MT/s speed with CL46 latency delivers rated throughput for the platform
  • ECC and registered architecture correct single-bit errors and offload the memory controller
  • 1 V operating voltage matches the server's electrical requirements exactly
  • 288-pin RDIMM form factor fits the GIGABYTE MZ33-AR1 motherboard slots precisely

Exact-match server upgrade

This 256GB kit delivers two 128GB DDR5 RDIMMs rated at 5600MHz with CL46 timing and 1.1V operation. Registered ECC architecture ensures full-capacity recognition and single-bit error correction on the GIGABYTE MZ33-AR1 motherboard.

Verify DIMM population rules

Check the motherboard manual for supported capacities per slot and the required installation order before ordering. The board requires 288-pin Registered RDIMMs; UDIMM or SODIMM modules will not fit or function.

Thermals noise and power draw

Modules run at the standard 1.1V DDR5 voltage with no heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw consistent during sustained server workloads.

Questions about this item

What is included in the box and does anything need to be purchased separately?

The kit contains two 128GB DDR5 5600MHz CL46 1.10V ECC Registered RDIMM modules in a matched 256GB set. No additional parts are required for installation.

How do I decide between the available capacities for this GIGABYTE MZ33-AR1 upgrade?

This listing is a single 256GB kit built from two 128GB RDIMMs. If your board supports that total capacity and population order, this is the correct choice; otherwise select a smaller validated kit.

What does the 5600MHz rating actually deliver once the memory is installed in the server?

The modules run at DDR5-5600 (PC5-44800) with CL46 latency at 1.10V, providing the exact speed and timing the MZ33-AR1 memory controller expects when fully populated with registered ECC DIMMs.
