Server memory kit for GIGABYTE MZ73-LM1

This 128GB kit contains two 64GB DDR5 4800MHz registered ECC RDIMMs built to the exact rank, voltage and timing the GIGABYTE MZ73-LM1 motherboard expects. The 2Rx4 organisation and 1.1V operation let the board recognise full capacity at rated speed without manual tuning.

Suited for registered DDR5 servers, not UDIMM builds

The modules suit administrators populating every slot on the MZ73-LM1 with registered ECC memory for maximum capacity and error correction. Builders needing unbuffered UDIMMs, non-ECC SODIMMs or a different DDR generation should look elsewhere because the pinout and signalling are incompatible.

2Rx4 registered ECC at 1.1V

The single specification that decides fitment is the 2Rx4 registered ECC organisation running at 1.1V CL40. Only motherboards qualified for this exact rank, voltage and buffering type will initialise the kit at 4800MHz PC5-38400.

Questions about this item

Should I choose the 128GB 2x64GB kit or a different capacity for my GIGABYTE MZ73-LM1?

The 128GB kit uses two 64GB DDR5 4800MHz CL40 2Rx4 Registered ECC RDIMMs at 1.1V, matching the exact rank, voltage and timing the MZ73-LM1 memory controller expects for full-capacity recognition.

What does the DDR5 4800MHz speed mean once installed in the server?

The modules will run at DDR5 4800 (PC5-38400) with CL40 latency, delivering the rated bandwidth the motherboard supports when all slots are populated with Registered ECC DIMMs.

How does the 288-pin RDIMM interface and Registered ECC design affect real-world operation?

The 288-pin Registered form factor offloads the memory controller so every slot runs fully populated at 128GB total, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
