  • 256GB total capacity from four 64GB modules for high-density server workloads
  • DDR5-5600 (PC5-44800) speed with CL46 latency matches the board's rated memory specification
  • Registered ECC RDIMM design offloads the memory controller and corrects single-bit errors automatically
  • 1V operating voltage meets DDR5 standard for lower power draw under full load
  • Verified compatibility with the GIGABYTE MZ33-AR1 motherboard ensures correct population and full-speed operation

Server memory upgrade for GIGABYTE MZ33-AR1

This 256 GB kit contains four 64 GB DDR5-5600 registered ECC RDIMMs built to the exact rank, voltage and timing the motherboard expects. The modules install in the 288-pin slots and are recognised at full capacity without manual configuration.

Sustained-load behaviour

Registered buffering removes electrical load from the memory controller so all four slots run fully populated at the rated 5600 MT/s data rate. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs or virtualisation workloads.

Thermals and power

Operating at 1.1 V, the modules draw minimal power and run without heat spreaders, relying on the server chassis airflow for cooling. The low-voltage design keeps system power draw predictable in densely populated rack environments.

Questions about this item

How much power does the 1.10 V DDR5-5600 kit draw when the server runs continuously?

Each module operates at 1.10 V DDR5 standard voltage; total system draw depends on CPU load and motherboard VRM efficiency, so consult your platform's power budget for exact figures.

What motherboard slot and firmware support are required for this 288-pin RDIMM kit?

The kit needs a GIGABYTE MZ33-AR1 or equivalent board with 288-pin DDR5 RDIMM slots and BIOS that supports 2Rx4 registered ECC at 5600 MT/s.

Will these 2Rx4 registered ECC modules work alongside older single-rank DDR5 UDIMMs?

No — registered RDIMMs and unbuffered UDIMMs cannot be mixed; all slots must use registered ECC DIMMs of matching rank and speed for stable operation.
