Capacity and compatibility

This is a 192GB DDR5 registered ECC memory kit built from twelve 16GB modules. It is validated for the GIGABYTE MZ23-SU0 motherboard running at DDR5-4800 with CL40 timings and 1.1V operation.

Who this suits

Server builders who need the exact rank, voltage and timing combination that the MZ23-SU0 memory controller expects for full-capacity recognition. Buyers who want unbuffered UDIMMs or non-ECC modules should look elsewhere.

Build integration

The 288-pin RDIMM form factor matches the board's registered DIMM slots, so every slot can be populated without signal-loading limits. ECC correction and registered buffering free the memory controller for stable operation at the rated 4800 MT/s speed.

Questions about this item

Does the GIGABYTE MZ23-SU0 motherboard require 12 DIMM slots to install this 192GB kit?

Yes, the kit contains 12 modules of 16GB each and uses the 288-pin RDIMM form factor, so the board must provide 12 DDR5 RDIMM slots to accept the full kit.

Can I mix these 1Rx8 Registered ECC modules with existing UDIMM or non-ECC DDR5 memory in the same server?

No, Registered ECC RDIMMs cannot be mixed with unbuffered UDIMMs or non-ECC modules; the memory controller requires identical registered ECC DIMMs across all populated channels.

How do I confirm the kit is running at DDR5-4800 CL40 1.1V after installation?

Enter the BIOS or use a hardware-information tool to verify the memory frequency reads 4800 MT/s, CAS latency shows CL40, and the voltage is set to 1.1V for all 12 modules.
