Server memory kit for GIGABYTE MZ23-SU0

This 256GB kit contains four 64GB DDR5 6400 Registered ECC RDIMMs built to the exact rank, voltage and timing the GIGABYTE MZ23-SU0 motherboard expects. It targets administrators who need full-capacity population on that specific platform without manual tuning.

Verify DIMM population rules before ordering

Consult your system or motherboard manual for supported capacities and the approved installation order for 288-pin RDIMMs. The board requires Registered modules, not UDIMM or SODIMM, and population limits vary by configuration.

Registered design keeps every slot stable at rated

The buffered architecture offloads the memory controller so all four slots run fully populated at DDR5 6400, while on-die ECC corrects single-bit errors during continuous operation to prevent silent data corruption.

Questions about this item

Does the kit include anything besides the four 64 GB DDR5 RDIMMs?

The package contains only the four 64 GB DDR5 6400 CL52 1.10 V ECC Registered RDIMMs. No heat spreaders, cables or tools are supplied.

Why choose the 256 GB 4 × 64 GB kit instead of a smaller capacity?

This kit delivers the full 256 GB in four matched 2Rx4 modules, letting the GIGABYTE MZ23-SU0 run every slot at the rated DDR5 6400 speed with registered ECC stability.

What does the DDR5 6400 CL52 rating mean once the modules are installed?

The memory will operate at 6400 MT/s with a CAS latency of 52 cycles at 1.10 V, providing the exact timing and voltage the server's memory controller expects for full-capacity registered ECC operation.
