  • 512 GB total capacity from four 128 GB modules for maximum server memory density
  • DDR5 5600 speed with CL46 latency delivers rated bandwidth for demanding workloads
  • Registered ECC design corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches the platform's voltage requirement for reliable POST
  • Verified fitment for the GIGABYTE MZ23-SU0 motherboard with 288-pin RDIMM form factor

Exact-match server upgrade

This 512 GB kit contains four 128 GB DDR5 5600 registered ECC RDIMMs built to the precise 2Rx4 rank, 1.10 V voltage and CL46 timing the memory controller expects. The modules install in the 288-pin slots and are verified for the GIGABYTE MZ23-SU0 motherboard so the full capacity is recognised at rated speed.

For fully populated enterprise servers

Suits administrators who need maximum registered ECC capacity in every slot for virtualisation hosts, database nodes or compute clusters where silent data correction matters. Not for workstations or desktops that accept only unbuffered UDIMMs, nor for boards limited to lower densities or slower DDR5 speeds.

Capacity and headroom

Four ranks per DIMM let the controller address the full 512 GB at DDR5 5600 without down-clocking, while registered buffering keeps signal integrity stable across all populated channels. ECC corrects single-bit errors on the fly, but the kit cannot exceed the motherboard's maximum supported capacity or populate slots beyond the board's qualified configuration.

Questions about this item

Does this kit require the GIGABYTE MZ23-SU0 motherboard to have four DDR5 RDIMM slots available?

Yes, the 512 GB kit contains four 128 GB 288-pin DDR5 RDIMM modules, so the board must provide four compatible DDR5 RDIMM slots.

Will the registered design and ECC function operate correctly if I populate all four slots on the MZ23-SU0?

The 2Rx4 registered ECC architecture is built for full-slot population, offloading the memory controller and correcting single-bit errors across all four modules.

How can I confirm the modules are running at DDR5 5600 CL46 after installation?

Check the BIOS or UEFI memory information screen; it should report 5600 MT/s, PC5-44800 and CL46 timings for each installed DIMM.
