1.5 TB DDR5 Registered ECC Kit for GIGABYTE MZ73-LM1

This twelve-module kit delivers 1.5 TB of DDR5 memory built for the GIGABYTE MZ73-LM1 server motherboard. Each 128 GB RDIMM operates at 6400 MT/s with CL52 latency and 1.10 V. The registered design and on-die ECC protect data integrity in multi-socket workloads.

2Rx4 rank layout matches controller expectations

The modules use a 2Rx4 organization that aligns with the memory controller’s population rules for full-capacity operation. Mixing different rank counts or unbuffered DIMMs would prevent the system from recognizing the full 1.5 TB at the rated 6400 MT/s speed.

Sustained throughput with registered buffering

Registered buffering offloads electrical load from the controller so all twelve slots remain stable at 6400 MT/s during continuous compute tasks. ECC corrects single-bit errors in real time, preventing silent corruption during long-running database or virtualization jobs.

Questions about this item

What does the 6400 MT/s speed actually deliver once the kit is installed in the GIGABYTE MZ73-LM1?

The kit runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.1 V, so the memory controller recognises the full 1.5 TB capacity and operates every slot at the rated data rate.

How does the registered ECC RDIMM interface affect what the motherboard can support?

Registered buffering offloads the memory controller, allowing all twelve 288-pin slots to be populated at 128 GB each while ECC corrects single-bit errors on the fly.

What physical requirements must the chassis meet to fit these twelve modules?

Each module is a standard 288-pin DDR5 RDIMM without a heat spreader, so the board needs twelve free DIMM slots and enough vertical clearance for bare modules.
