288 GB DDR5-6400 ECC RDIMM kit

This six-module kit delivers 288 GB of DDR5-6400 registered ECC memory for the GIGABYTE MZ23-SU0 motherboard. Each 48 GB module operates at 1.1 V with CL52 latency and a 2Rx8 organisation. The registered design and error-correction code target servers that require maximum capacity and data integrity.

288-pin RDIMM form factor and population rules

The modules use the 288-pin RDIMM form factor required by the board; they are not compatible with UDIMM or SODIMM slots. Full-capacity operation depends on following the motherboard's approved DIMM population order and supported capacity limits. Consult the system manual before installation to confirm slot sequence and any BIOS settings needed for recognition at rated speed.

Registered buffer and ECC under sustained load

The registered buffer reduces electrical load on the memory controller, allowing all six slots to run at the rated 6400 MT/s continuously. ECC corrects single-bit errors in real time, preventing silent data corruption during extended workloads. Stable 1.1 V operation supports consistent throughput without voltage drift during long-running server tasks.

Questions about this item

Will the CL52 latency limit throughput when the kit runs at DDR5-6400 continuously?

The modules are rated CL52 at DDR5-6400 (PC5-51200); that timing is the specification the memory controller expects for full-speed operation.

How do the 1.1V registered DIMMs behave for heat and power during all-day loads?

Registered architecture offloads the memory controller and the 1.1V operating voltage keeps power draw low, so the six modules run cool without heat spreaders.

What motherboard slot layout and population rules must my GIGABYTE MZ23-SU0 already have for this 6×48GB kit to work?

The board needs six 288-pin RDIMM slots and must support 2Rx8 registered ECC DIMMs populated per its manual's approved order.
