  • DDR5 5600 MT/s speed feeds data to the CPU at rated throughput
  • CL46 latency and 1.1 V operation match the memory controller's exact timing requirements
  • Registered ECC design corrects single-bit errors and supports full population on the GIGABYTE MZ33-AR1
  • 288-pin 2Rx8 RDIMM form factor fits the board's memory-population rules

Purpose-built server upgrade

This 48GB DDR5 registered DIMM is an exact-match upgrade for the GIGABYTE MZ33-AR1 motherboard. It delivers ECC protection and registered buffering so every slot can run fully populated at rated speed. The module targets administrators who need guaranteed compatibility without manual tuning. Buyers needing non-ECC unbuffered memory for consumer platforms cannot use this part.

Capacity and headroom

The single 48GB rank-2Rx8 module operates at DDR5-5600 (PC5-44800) with CL46 latency at 1.1V. Registered architecture offloads the memory controller, allowing full-capacity population across all supported slots. Workloads that exceed the installed module count or require speeds beyond 5600MT/s will need additional qualified DIMMs or a platform change.

Thermals and power

The module runs at the standard DDR5 1.1V without a heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping keep system power draw predictable. In typical server chassis with directed airflow the DIMM stays within thermal limits without audible fan-speed increases.

Questions about this item

Will this 48 GB DDR5 5600 RDIMM work alongside my existing DDR5 5600 modules in the GIGABYTE MZ33-AR1?

The module is validated for the GIGABYTE MZ33-AR1 at DDR5 5600, 1.1 V, CL46, 2Rx8 Registered ECC. Matching speed, voltage, latency, rank and ECC type across all slots lets the memory controller run the full population at the rated 5600 MT/s.

How can I confirm the 48 GB DDR5 5600 RDIMM is running at its rated speed after installation?

Enter the BIOS and verify the memory frequency shows 5600 MT/s (PC5-44800) with CL46 timings at 1.1 V; the POST screen or a tool such as dmidecode should also report 48 GB per DIMM, Registered ECC, 2Rx8 organisation.

What comes in the box and what must I source separately?

The package contains the 48 GB DDR5 5600 288-pin RDIMM (MR44800-4828K1). No heat spreader, cables, screws or additional DIMMs are included; buy extra modules separately if your configuration requires more capacity.
