Exact-Match Server Upgrade

This 32GB kit contains two 16GB DDR5-6400 registered ECC RDIMMs built to the GIGABYTE MZ73-LM2 motherboard's exact specifications. The modules run at 1.1V with CL52 latency and a 1Rx8 rank structure so the memory controller recognises the full capacity immediately and operates at the rated PC5-51200 speed without manual tuning.

Build And Connector Details

Each module uses the 288-pin RDIMM form factor required by the board; it is not a UDIMM or SODIMM and will not fit those slots. The registered architecture buffers address and command signals, allowing every populated slot to run at full load while on-die ECC corrects single-bit errors in real time to prevent silent data corruption.

Replaces Non-ECC Or Mismatched Kits

The kit upgrades systems currently running unbuffered non-ECC memory or slower DDR5 modules that cannot sustain the platform's native 6400 MT/s rate. The jump is worth it when workloads demand maximum registered-DIMM capacity per channel and error correction, but it is not for buyers who need consumer UDIMM pinouts, lower voltages, or modules without ECC overhead.

Questions about this item

What speed does the DDR5-6400 interface run at on this kit?

The kit operates at DDR5-6400 (PC5-51200) with a CAS latency of CL52, delivering the rated transfer rate the GIGABYTE MZ73-LM2 memory controller expects.

What physical slot and form factor do these modules require?

Each module is a 288-pin registered RDIMM, the exact form factor the GIGABYTE MZ73-LM2 motherboard requires; UDIMM or SODIMM modules will not fit.

How do I install the two 16 GB sticks in the correct order?

Consult the GIGABYTE MZ73-LM2 manual for the approved DIMM population sequence, then seat both registered ECC modules firmly until the retention clips lock.
