  • Exact DDR5-5600 CL46 2Rx8 ECC Registered kit matches GIGABYTE MZ73-LM1 memory controller for full-speed recognition
  • 64 GB capacity in two 32 GB modules enables maximum supported density per slot on this platform
  • Registered architecture buffers address and command signals so every DIMM slot runs stable at rated frequency
  • On-die ECC corrects single-bit errors in real time preventing silent data corruption in production workloads
  • Built with major-brand Samsung Micron Hynix DRAM chips validated for enterprise server reliability

Exact-Match Server Upgrade

This 64 GB kit contains two 32 GB DDR5-5600 Registered ECC RDIMMs built for the GIGABYTE MZ73-LM1 motherboard. Each module runs at 1.1 V with CL46 timing and a 2Rx8 organisation so the memory controller recognises the full capacity immediately.

Replaces Slower or Smaller Kits

Swapping out lower-speed DDR5 or partially populated RDIMM sets restores the bandwidth and rank balance the board expects. The jump is worth it when every slot must run at the rated 5600 MT/s without down-clocking or population limits.

Fits a Fully Populated Registered Build

The 288-pin RDIMM form factor matches the server board's registered slots and buffered architecture, offloading the memory controller for stable operation at full capacity. ECC corrects single-bit errors on the fly. Buyers needing unbuffered UDIMMs or non-ECC memory for workstation boards cannot use this kit.

Questions about this item

Does the 288-pin RDIMM form factor fit the GIGABYTE MZ73-LM1 motherboard?

Yes, this kit uses the exact 288-pin Registered DDR5 RDIMM form factor required by the GIGABYTE MZ73-LM1 motherboard and is not a UDIMM or SODIMM.

What installation step is often missed when populating both 32GB modules?

Follow the motherboard manual's specific DIMM population order for registered ECC memory to ensure both 32GB modules are recognized at full 64GB capacity and rated DDR5-5600 speed.

Will the ECC and registered features require any ongoing maintenance?

No, ECC error correction and registered buffering operate automatically in hardware with no user maintenance needed for the lifetime of the modules.
