Exact-Match Server Upgrade

This 128GB kit delivers eight 16GB DDR5 RDIMMs rated at 6400MT/s with CL52 latency and 1.1V operation. Registered ECC architecture and 1Rx8 organisation provide the precise signal integrity and error correction that production servers require.

Build Integration

Each 288-pin module fits the GIGABYTE MZ23-SU0 motherboard's registered DIMM slots and follows its population rules for full-capacity recognition. The registered buffer reduces electrical load on the memory controller so all eight slots can run populated without signal degradation.

Sustained Operation

ECC circuitry corrects single-bit errors in real time, preventing silent data corruption during continuous workloads. Registered buffering maintains stable timing across every channel when the system runs fully loaded for extended periods.

Questions about this item

How many memory slots does the GIGABYTE MZ23-SU0 board need free for this 8-module kit?

The kit contains 8 registered DIMMs, so the board must provide 8 free DDR5 RDIMM slots.

What sustained power draw should I expect from the 128 GB kit at its rated 1.10 V?

Each module runs at 1.10 V; total draw scales with all 8 modules active under load.

Which motherboard must already be installed for this memory to be recognised at full speed?

The kit is validated for the GIGABYTE MZ23-SU0 motherboard running DDR5 6400.
