Exact DDR5-5600 ECC RDIMM kit for GIGABYTE MZ73-LM2

This 64 GB kit contains two 32 GB DDR5-5600 Registered ECC modules built to the PC5-44800 standard. It is intended for administrators upgrading or populating the GIGABYTE MZ73-LM2 motherboard with memory that matches the board's qualified vendor list.

Keyed 288-pin RDIMM form factor prevents

The modules use the 288-pin Registered DIMM layout required by the MZ73-LM2, so they only fit the correct server slots and cannot be inserted into UDIMM or SODIMM sockets. Verify the motherboard manual for approved population order and maximum supported capacity before seating the DIMMs, as incorrect slot filling or exceeding the platform limit will prevent boot.

Registered ECC with 2Rx8 organisation at 1.1 V

The combination of Registered buffering, ECC error correction, dual-rank 2Rx8 architecture and 1.1 V operation is the single specification that determines compatibility with the MZ73-LM2 memory controller; a different rank count, voltage or unbuffered type will not be recognised at full speed or capacity.

Questions about this item

How do I confirm the kit runs at 5600 MHz with CL46 after installation?

Enter the BIOS or UEFI and verify the memory frequency shows 5600 MT/s and CAS latency reads 46; the registered ECC design lets the controller train at the rated speed when populated per the motherboard manual.

What ships in the package and what must I source separately?

The box contains the 64 GB kit as two 32 GB 288-pin DDR5 RDIMMs; no heat spreaders, cables, or tools are included, and the motherboard itself is purchased separately.

Which capacity version should I choose for the GIGABYTE MZ73-LM2?

Select the 64 GB 2 x 32 GB DDR5-5600 RDIMM kit (part MR44800-328K2) — it matches the board's registered ECC requirement, 1.1 V voltage, 2Rx8 rank, and 288-pin form factor.
