  • 288-pin 2Rx4 form factor ensures mechanical and electrical compatibility with the target platform

Exact-match server upgrade

This 256 GB kit contains two 128 GB DDR5 RDIMM modules rated at 6400 MT/s with CL52 latency and 1.1 V operation. It is built for the GIGABYTE MZ73-LM2 motherboard and targets administrators who need registered ECC memory that runs at full capacity across every populated slot.

Verify board population rules

The MZ73-LM2 requires 288-pin registered DIMMs and follows specific population orders that differ by CPU configuration. Check the motherboard manual for approved capacities per channel, slot-filling sequence, and any BIOS revision notes before installing these 2Rx4 modules.

Registered ECC stability daily

Registered buffering reduces electrical load on the memory controller so all slots remain stable when fully populated, while on-die ECC corrects single-bit errors without halting the system. The modules ship without heat spreaders, so chassis airflow must handle thermal dissipation in dense server configurations.

Questions about this item

Does the 256 GB 2 x 128 GB kit include everything needed to populate two DDR5 RDIMM slots on a Gigabyte MZ73-LM2 motherboard?

Yes, the kit ships as a matched pair of two 128 GB registered ECC RDIMMs so you can fill two 288-pin slots immediately without buying extra modules.

Should I choose this 256 GB CL52 kit or a lower-capacity alternative for the MZ73-LM2?

Pick this 2 x 128 GB kit when the workload needs the full 256 GB registered ECC capacity at DDR5-6400; smaller kits exist but will not provide the same total memory.

What does the DDR5-6400 (PC5-51200) rating mean once the modules are installed in the server?

The memory controller will run the RDIMMs at 6400 MT/s with CL52 latency at 1.1 V, delivering the rated bandwidth and ECC error correction the platform expects.
