Exact-match server upgrade

This 1.5 TB kit delivers twelve 128 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. Registered ECC architecture matches the GIGABYTE MZ23-SU0 memory controller so every slot is recognised at full capacity and rated speed.

Sustained enterprise stability

Registered buffering offloads the memory controller allowing all twelve modules to run fully populated without signal degradation. ECC corrects single-bit errors on the fly preventing silent data corruption and unplanned reboots during continuous production workloads.

Dense 2Rx4 registered form factor

The 288-pin RDIMM layout fits only boards that require registered memory; UDIMM or SODIMM slots will not accept these modules. Population order and maximum capacity must be verified against the motherboard manual before installation.

Questions about this item

Does the 1.1V operating voltage of these DDR5 6400 RDIMMs reduce heat output when the server runs continuously?

The 1.1V voltage is the standard for DDR5 and helps limit power draw and heat across all 12 modules during sustained workloads.

What motherboard features are required for this 1.5TB kit to function correctly?

The GIGABYTE MZ23-SU0 motherboard must support 288-pin DDR5 RDIMMs with registered ECC, 2Rx4 organisation, and a population order that allows twelve 128GB modules.

Will the registered ECC design of these DDR5 6400 modules work alongside older registered DDR5 RDIMMs in the same server?

Mixing is not recommended; the kit is validated as a matched 12-module set for the MZ23-SU0, and adding different modules can prevent the memory controller from running the full 1.5TB at 6400 MT/s.
