384GB DDR5-6400 ECC RDIMM kit

This 384GB kit contains four 96GB DDR5-6400 Registered ECC modules built for the GIGABYTE MZ23-SU0 motherboard. Each DIMM runs at 1.1V with CL52 latency and a 2Rx4 organisation. The registered design lets the memory controller address every slot at full capacity without signal degradation.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller so all four slots remain stable when fully populated. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The low 1.1V operating voltage keeps power draw predictable under continuous throughput.

Build and connectors

Modules use the standard 288-pin RDIMM form factor with no heat spreader, fitting the board's keyed slots in the prescribed population order. Major-brand Samsung, Micron or Hynix DRAM chips are used throughout. Verify the motherboard manual for exact slot sequence and maximum supported capacity before installation.

Questions about this item

How much heat and power do these 1.1V DDR5 6400 modules produce when the server runs all day?

Each 96GB RDIMM operates at 1.10V and DDR5 6400 speed. Registered buffering reduces electrical load on the memory controller, so a fully populated kit draws less current per DIMM than unbuffered alternatives, keeping thermals manageable in 24/7 operation.

What motherboard and CPU combination is required for this 384GB kit to function?

The kit is validated for the GIGABYTE MZ23-SU0 motherboard with DDR5 6400 support. A compatible processor that provides eight DDR5 channels and accepts 2Rx4 registered ECC DIMMs is also required for full 384GB capacity.

Can I mix these 2Rx4 registered ECC DIMMs with any existing RDIMMs already installed in the same server?

All four slots must use identical 96GB 2Rx4 DDR5 6400 registered ECC modules. Mixing different ranks, capacities, or speeds will prevent the memory controller from training at the rated 6400 MT/s and may disable ECC.
