  • 256GB total capacity lets you maximise server memory density with eight 32GB modules
  • DDR5 5600MHz PC5-44800 speed matches the board's rated frequency for full-performance operation
  • CL46 CAS latency and 1.1V voltage meet the exact timing and power specs the memory controller expects
  • ECC Registered RDIMM architecture corrects single-bit errors on the fly while buffering signals for stable full-population operation
  • Verified fitment for the GIGABYTE MZ73-LM1 motherboard ensures the 288-pin RDIMM form factor and population rules are satisfied

Exact-match upgrade kit

This 256GB kit delivers eight 32GB DDR5 5600 RDIMMs tuned to CL46 at 1.1V. It is built for the GIGABYTE MZ73-LM1 motherboard and matches the board's required 2Rx8 registered ECC specification. The modules populate every slot at full capacity without manual tuning.

Sustained enterprise stability

Registered architecture buffers the command bus so all eight slots run fully populated at rated speed under continuous load. On-die ECC corrects single-bit errors in real time preventing silent data corruption during long compute runs. The 1.1V operating voltage keeps power draw predictable across extended duty cycles.

Build and daily implications

Bare 288-pin RDIMMs without heat spreaders rely on server chassis airflow for cooling. The registered form factor is mandatory for this platform and will not fit UDIMM or SODIMM slots. Buyers needing non-ECC unbuffered memory or consumer desktop compatibility should look elsewhere.

Questions about this item

Does the 1.1V 5600MHz kit run hotter or louder than lower-speed memory when the server runs all day?

The modules operate at the standard DDR5 voltage of 1.1V with no heat spreader, so thermal output matches the board's design envelope and there are no moving parts to create noise.

What motherboard and slot type must I already have for this 288-pin RDIMM kit to work?

You need a GIGABYTE MZ73-LM1 motherboard with DDR5 RDIMM slots that accept 288-pin registered ECC modules.

Can I mix these 2Rx8 CL46 modules with older DDR5 sticks already in the server?

Mixing ranks, speeds or latencies is not recommended; the board expects identical 2Rx8 CL46 modules in every populated slot for stable registered ECC operation.
