Server memory upgrade for GIGABYTE MZ23-SU0

This 48 GB DDR5 RDIMM is built for the GIGABYTE MZ23-SU0 motherboard. It delivers registered ECC operation at the exact speed and timing the platform expects. System integrators and IT teams can populate every slot with confidence.

Registered ECC design with 288-pin DDR5 form factor

The module uses a registered architecture that buffers address and command signals, reducing electrical load on the memory controller when all channels are full. ECC circuitry detects and corrects single-bit errors on the fly, helping prevent silent data corruption in production workloads. No heat spreader is fitted, so airflow in dense chassis is unimpeded.

48 GB capacity at DDR5-4800 CL40 1.1 V

The single specification that decides fit is the 48 GB 2Rx8 Registered ECC profile running at DDR5-4800 with CL40 latency and 1.1 V. Boards that require UDIMM, SODIMM, non-ECC, or a different rank configuration will not accept this module. Verify your system manual for supported capacities and population rules before ordering.

Questions about this item

What DDR5 speed and PC5 rating does this 48GB RDIMM run at?

The module operates at DDR5 4800 with a PC5-38400 data rate, delivering the exact transfer rate the GIGABYTE MZ23-SU0 memory controller expects.

Which physical slot and pin count does this registered ECC module require?

It uses a 288-pin DDR5 RDIMM form factor, so it fits only a registered DIMM slot on the GIGABYTE MZ23-SU0 — not a UDIMM or SODIMM socket.

What population order should I follow when installing this 2Rx8 kit?

Consult the GIGABYTE MZ23-SU0 manual for the approved DIMM population sequence; installing in the wrong slot order can prevent the system from recognising the full 48GB capacity.
