Exact-match DDR5 ECC RDIMM for MZ73-LM2

This 64 GB DDR5 6400 CL52 module is built for the GIGABYTE MZ73-LM2 motherboard. Registered ECC architecture lets the board run fully populated at rated speed while correcting single-bit errors on the fly. It is intended for server workloads that demand data integrity and maximum capacity per slot.

Fits 288-pin registered DIMM slots at 1.1 V

The board must provide DDR5 RDIMM sockets and support 2Rx4 population rules; a UDIMM or SODIMM will not work. Registered buffering offloads the memory controller so every slot stays stable at full load. No heat spreader is included, so chassis airflow must handle the thermal load.

64 GB per module at PC5-51200

One stick delivers 64 GB of ECC-protected capacity at 6400 MT/s with CL52 latency. It handles large virtualisation hosts, database buffers and compile farms comfortably. Workloads that need more than 64 GB per slot or non-registered memory cannot use this part.

Questions about this item

Does the CL52 latency limit throughput when the module runs at 6400 MT/s all day?

CL52 is the rated timing at DDR5 6400; the registered buffer and ECC keep every slot stable at full speed under sustained load.

How much heat and power does a 1.1 V 2Rx4 registered DIMM produce in 24/7 operation?

At 1.1 V the module draws minimal power and runs without a heat spreader, so thermal output stays low even when fully populated.

Must the GIGABYTE MZ73-LM2 motherboard already support 288-pin DDR5 RDIMM population rules for this kit to work?

Yes — the board must accept 288-pin registered DDR5 DIMMs and follow its manual’s population order for the 64 GB module to be recognised.
