32GB DDR5-6400 ECC RDIMM for GIGABYTE MZ23-SU0

This 32GB DDR5 6400 module is built for the GIGABYTE MZ23-SU0 motherboard. It uses a 288-pin Registered DIMM form factor with ECC and a 2Rx8 organisation. The 1.1V operating voltage and CL52 latency match the board's memory controller requirements exactly.

Capacity and registered headroom

The 32GB capacity fits single-slot upgrades or multi-DIMM populations where the platform supports it. Registered buffering lets the memory controller drive every populated slot at the rated 6400 speed without signal degradation. Systems that need larger per-slot densities or higher frequencies will exceed what this module provides.

DDR5-6400 interface limits

The DDR5 6400 (PC5-51200) interface delivers 51200 MB/s peak bandwidth at CL52. JEDEC-standard voltage is 1.1V, so no over-voltage headroom exists for manual tuning. Boards limited to lower DDR5 data rates or to unbuffered DIMMs cannot use this module at its rated specification.

Questions about this item

Will this 32GB DDR5 6400 RDIMM install in a GIGABYTE MZ23-SU0 motherboard that already has older DDR5 modules in other slots?

This module is an exact-match upgrade for the GIGABYTE MZ23-SU0; consult the motherboard manual for the approved DIMM population order before mixing capacities or ranks.

How do I confirm the 2Rx8 ECC RDIMM is running at its rated speed and ECC is active after installation?

Enter the BIOS or UEFI and verify the memory shows 32GB capacity, 6400MT/s data rate, and ECC enabled.

Does the package include more than the single 32GB 288-pin DDR5 6400 CL52 1.1V ECC RDIMM module itself?

The package content lists only the 32GB DDR5 6400MHz PC5-51200 2Rx8 1.1V 288-PIN ECC RDIMM kit; no extra cables, brackets, or cooling accessories are included.
