Exact DDR5-5600 ECC RDIMM kit for GIGABYTE MZ23-SU0

This 256GB kit contains two 128GB DDR5 registered DIMMs built for the GIGABYTE MZ23-SU0 motherboard. It targets server administrators who need maximum capacity per slot and hardware error correction. The modules ship new and ready for immediate installation.

Registered 2Rx4 organisation with 1.10V operation

The single specification that decides fitment is the 2Rx4 registered ECC architecture running at 1.10V. Only motherboards wired for registered DDR5 RDIMMs at this voltage and rank structure will recognise the full 256GB and run at the rated 5600 speed. UDIMM or SODIMM boards cannot use these modules.

Passive design runs at standard DDR5 voltage

Without heat spreaders the modules rely on chassis airflow, yet the 1.10V operating point keeps power draw at the DDR5 baseline. Registered buffering reduces electrical load on the memory controller, so fully populated slots stay within normal thermal limits and produce no audible noise.

Questions about this item

What does the DDR5 5600 speed rating deliver when the kit is installed in a server?

The modules run at 5600 MT/s with CL46 latency and 1.10 V, providing the exact data rate and timing the memory controller expects for full-capacity operation.

How does the 288-pin RDIMM registered interface affect maximum capacity on the GIGABYTE MZ23-SU0?

Registered buffering offloads the memory controller so every slot can be fully populated at the rated 5600 speed without signal degradation.

Will the 288-pin form factor fit the DIMM slots on a GIGABYTE MZ23-SU0 motherboard?

Yes, the 288-pin RDIMM matches the board's required DDR5 registered DIMM slot keying and physical dimensions.
