Exact-match DDR5 server kit

This 256 GB kit contains four 64 GB DDR5 5600 RDIMM modules built to the GIGABYTE MZ73-LM1 motherboard's exact rank, voltage and timing requirements. It targets administrators who need the full registered ECC capacity this platform supports.

Straightforward RDIMM install

The 288-pin registered DIMMs seat like any server memory, but population order matters on this board. Skipping the manual's slot sequence or mixing ranks is the usual cause of POST failures or reduced capacity.

Sustained registered ECC stability

Registered buffering offloads the memory controller so all four slots run at the rated 5600 MT/s and CL46 latency under continuous load. ECC corrects single-bit errors on the fly, preventing silent corruption during long compute runs.

Questions about this item

How can I verify the 256GB kit is running at DDR5 5600 with CL46 after installation?

Check the BIOS or UEFI memory information screen — it should show 5600 MT/s, 1.10 V, and CL46 timings for all four 64GB modules.

What is included in the MR44800-924K4 package and do I need any extra parts?

The kit contains four 64GB DDR5 5600 288-pin ECC Registered RDIMM modules; no additional components are required for installation on the GIGABYTE MZ73-LM1.

Why choose the 256GB (4×64GB) 2Rx4 Registered ECC version instead of a smaller kit?

This configuration matches the MZ73-LM1's population rules for full-capacity operation, providing registered buffering and ECC for stable, error-corrected performance across all slots.
