Exact-match 1.5 TB DDR5-5600 kit for GIGABYTE

This 12-module kit delivers 1.5 TB of DDR5 ECC registered memory at 5600 MHz with CL46 latency. Each 128 GB DIMM operates at 1.1 V using a 2Rx4 organization. The registered design and on-die ECC provide the stability required for multi-socket server workloads on the GIGABYTE MZ73-LM0 platform.

Verify manual population rules and slot limits

Before ordering, consult the motherboard manual for the supported maximum capacity per DIMM and the approved population sequence for twelve modules. The board requires 288-pin registered DIMMs; unbuffered or SODIMM modules will not function. Confirm that the BIOS version installed recognises the full 1.5 TB configuration at the rated DDR5-5600 speed.

Registered design reduces controller load at 1.1 V

The registered architecture buffers address and command signals, lowering electrical load on the memory controller when all twelve slots are populated. Operating at 1.1 V keeps power draw modest for the total capacity. ECC corrects single-bit errors in real time, preventing silent data corruption during sustained compute tasks.

Questions about this item

Does the 1.5TB kit contain twelve 128GB modules or must I buy extra DIMMs?

The kit ships with twelve 128GB DDR5 RDIMMs, giving the full 1.5TB capacity in one package; no additional modules are required.

Should I pick the 5600MHz CL46 2Rx4 version or a different speed for the MZ73-LM0?

The MZ73-LM0 is validated for DDR5-5600 (PC5-44800) CL46 2Rx4 registered ECC; this exact specification matches the board's qualified memory list.

Will the 5600MHz rating actually run at 5600MHz once installed in the server?

Yes, the modules are spec-matched to the motherboard's memory controller, so all twelve slots operate at the rated 5600MHz with ECC active.
