Exact-Match DDR5 Server Upgrade

This 64GB DDR5-6400 RDIMM delivers PC5-51200 bandwidth at 1.1V with CL52 latency. The 2Rx4 registered ECC design matches the GIGABYTE MZ23-SU0 motherboard's memory controller expectations so the module is recognised at full capacity and rated speed.

Suited For Enterprise Servers

Ideal for administrators populating every slot on the MZ23-SU0 with registered ECC modules that correct single-bit errors on the fly. Builders needing unbuffered UDIMMs, SODIMM form factors, or non-ECC memory for workstations should look elsewhere.

Sustained Load Stability

Registered buffering offloads the memory controller, allowing full-slot populations to maintain rated throughput during extended workloads. ECC detection and correction prevents silent data corruption and unplanned reboots before they reach production environments.

Questions about this item

What motherboard must I already have for this 64 GB DDR5-6400 2Rx4 registered ECC RDIMM to work?

This module is validated for the GIGABYTE MZ23-SU0 motherboard and requires a 288-pin DDR5 RDIMM slot that supports registered ECC memory at 1.1 V.

Will this registered ECC RDIMM run alongside older unbuffered non-ECC DDR5 DIMMs I might keep installed?

No. Registered ECC RDIMMs cannot be mixed with unbuffered non-ECC DIMMs; the memory controller will not initialise a mixed population.

How can I verify the kit is running at its rated 6400 MT/s with ECC active after installation?

Enter the system BIOS and confirm the memory frequency shows 6400 MT/s, the voltage reads 1.1 V, and ECC status reports enabled.
