64 GB DDR5 ECC RDIMM kit

This 64 GB kit contains two 32 GB DDR5 4800 Registered ECC RDIMMs built for the GIGABYTE MZ73-LM0 motherboard. The modules run at 1.1 V with CL40 latency and a 2Rx8 rank structure. Registered buffering lets the memory controller manage a full population without signal degradation.

Who should consider this kit

Server administrators who need the exact DDR5 4800 RDIMM specification validated for the MZ73-LM0 platform should buy this kit. Workstations or desktops that accept only unbuffered UDIMMs cannot use Registered memory. Systems limited to lower capacities per slot or a different DDR generation will not recognise these modules.

Matching DDR5 4800 RDIMM specification

The motherboard requires DDR5 4800 PC5-38400 Registered ECC RDIMMs with 2Rx8 organisation at 1.1 V. This kit meets that exact speed, voltage, rank, and form-factor combination so the firmware detects full capacity at rated timings. A different speed, voltage, rank, or unbuffered type will prevent the system from booting or running stably.

Questions about this item

What motherboard must I already own for this 2Rx8 DDR5-4800 RDIMM kit to be recognised at full 64 GB capacity?

The kit is validated for the GIGABYTE MZ73-LM0 motherboard running DDR5-4800 PC5-38400; the board must accept 288-pin registered ECC DIMMs at 1.1 V with CL40 timing.

Will these registered ECC modules work in the same channels as any existing UDIMMs I keep in the MZ73-LM0?

No — the MZ73-LM0 requires registered RDIMMs; mixing UDIMMs with this 2Rx8 registered kit is not supported and will prevent the system from posting.

How can I confirm the kit is running at its rated DDR5-4800 CL40 1.1 V after installation?

Enter the BIOS and verify the memory frequency shows 4800 MT/s, CAS latency reads CL40, voltage reads 1.1 V, and the total capacity reports 64 GB across both DIMMs.
