  • 384GB total capacity across eight 48GB modules enables large-scale workloads
  • DDR5 4800 speed with CL40 latency delivers rated throughput for server tasks
  • ECC and registered design corrects errors and stabilises fully populated slots
  • 1V operation matches the motherboard's memory controller specification exactly
  • 288-pin RDIMM form factor fits the GIGABYTE MZ23-SU0 without adapters

Exact-fit server upgrade

This 384 GB kit delivers eight 48 GB DDR5 4800 RDIMMs built to the precise rank, voltage and timing the GIGABYTE MZ23-SU0 expects. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. The modules install as a matched set so the memory controller recognises full capacity immediately.

Sustained-load behaviour

Registered buffering offloads the memory controller so all eight slots stay stable at 4800 MT/s under continuous throughput. ECC detection and correction runs in hardware without software overhead preventing silent data corruption during long compute runs. The 1.1 V operating point keeps power draw consistent across the fully populated array.

Deciding specification

The motherboard requires 288-pin DDR5 RDIMMs at 4800 MT/s with 2Rx8 organisation and CL40 latency. Any kit that differs in rank, voltage or form factor will not post at full capacity. Buyers needing UDIMM, SODIMM or non-ECC modules should look elsewhere.
