Exact-match server upgrade

This 128GB DDR5-5600 module delivers PC5-44800 bandwidth at CL46 with a 1.10V operating voltage. The 2Rx4 registered ECC design matches the GIGABYTE MZ73-LM1 memory controller so the system recognises full capacity at rated speed. It is built for servers that require registered DIMMs rather than unbuffered or SODIMM alternatives.

Sustained-load stability

Registered architecture buffers each command, letting every slot run fully populated without overloading the memory controller. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption during continuous workloads. The module maintains its specified timing and voltage across extended operating periods in multi-DIMM configurations.

Build and daily fit

The 288-pin RDIMM form factor seats directly in the board's registered DIMM slots without adapters. Absence of a heat spreader keeps the profile low for dense chassis layouts. Major OEM DRAM from Samsung, Micron or Hynix underpins long-term reliability in 24/7 server environments.

Questions about this item

How much power does the 1.10 V DDR5 5600 RDIMM draw when the server runs all day?

Each module operates at 1.10 V DDR5 standard voltage; total system power depends on how many of the 288-pin RDIMM slots your motherboard populates and the workload, so consult the GIGABYTE MZ73-LM1 manual for per-slot and full-population figures.

What motherboard feature must already be present for this 128 GB 2Rx4 Registered ECC kit to work?

The board needs DDR5 RDIMM slots that support 2Rx4 Registered ECC modules at 5600 MT/s (PC5-44800) with a 1.10 V supply — the GIGABYTE MZ73-LM1 is the verified platform.

Will this 288-pin DDR5 RDIMM install in the same slots as older DDR5 UDIMM or SODIMM modules I might keep?

No — RDIMM, UDIMM and SODIMM are mechanically and electrically different; this kit only fits DDR5 RDIMM slots, so any retained modules must also be RDIMMs.
