576GB DDR5-6400 ECC RDIMM Kit

This 576GB kit contains six 96GB DDR5-6400 registered ECC modules built for the GIGABYTE MZ23-SU0 motherboard. Each 288-pin RDIMM runs at 1.1V with CL52 latency and a 2Rx4 rank configuration. The registered buffer and error-correcting code suit multi-socket server workloads that demand full-capacity population across every slot.

Sustained Load Stability

Registered architecture offloads the memory controller so all six slots operate at the rated 6400 MT/s when fully populated. ECC corrects single-bit errors on the fly, preventing silent data corruption during long-running compute or database tasks. The 1.1V operating voltage keeps power draw consistent across extended duty cycles without thermal throttling.

DDR5-6400 Interface Limits

The PC5-51200 standard caps transfer rate at 6400 MT/s per pin, so bandwidth scales with channel count rather than higher clock speeds. CL52 latency is fixed by the module's SPD profile and cannot be tightened without violating the qualified voltage of 1.1V. Population rules for the MZ23-SU0 may restrict maximum capacity per channel, so consult the board manual before installing all six modules.

Questions about this item

How much power does the 576GB kit draw at its rated 1.1V?

Each 96GB module operates at 1.1V, so the six DIMMs together run at the DDR5 standard 1.1V supply; total system power will depend on the GIGABYTE MZ23-SU0 motherboard's VRM efficiency and the CPU's memory-controller load.

Does the GIGABYTE MZ23-SU0 motherboard need a specific BIOS version or CPU to recognise all 576GB?

The kit is validated for the GIGABYTE MZ23-SU0 at DDR5 6400 CL52; you must check the motherboard manual for supported DIMM population order, maximum capacity per slot, and any required BIOS revision before installing all six 96GB RDIMMs.

Can I mix these 96GB 2Rx4 RDIMMs with smaller DDR5 ECC modules already in the server?

Mixing different capacities or ranks is not recommended; the MZ23-SU0's memory controller expects identical 2Rx4 registered DIMMs in each channel to run at the rated 6400 MT/s with ECC active.
