  • 256 GB total capacity with eight 32 GB modules for maximum server density
  • DDR5 4800 speed at CL40 latency delivers rated throughput for the GIGABYTE MZ73-LM2
  • ECC and registered design corrects single-bit errors and offloads the memory controller
  • 10 V operation matches the board's voltage spec for stable full-population runs
  • 288-pin RDIMM form factor ensures exact mechanical and electrical fit in every slot

256GB DDR5-4800 ECC RDIMM Kit

This 256GB kit contains eight 32GB DDR5-4800 (PC5-38400) Registered ECC RDIMMs. Each module runs at 1.1V with CL40 latency and a 2Rx8 organisation. The 288-pin form factor matches the GIGABYTE MZ73-LM2 motherboard memory slots exactly.

Server builds needing registered ECC at full

Suited for administrators populating every slot on a MZ73-LM2 board with registered ECC memory. Not for systems that require unbuffered UDIMMs, non-ECC modules, SODIMM form factors, or a different DDR generation.

Straightforward slot installation with manual checks

Modules insert into the 288-pin DDR5 slots like standard RDIMMs. Issues usually arise when the board manual population order is ignored or when the BIOS is not updated for full 256GB recognition.

Questions about this item

Does this 288-pin DDR5 RDIMM kit require a GIGABYTE MZ73-LM2 motherboard that supports registered ECC memory?

Yes, the kit is validated for the GIGABYTE MZ73-LM2 motherboard and requires a platform that accepts 288-pin registered ECC DDR5 modules.

Will these 2Rx8 registered modules work if I keep older single-rank DDR5 DIMMs in the same server?

Mixing 2Rx8 registered DIMMs with single-rank modules is not recommended; the memory controller treats each rank differently and may downclock or disable slots.

How can I confirm the full 256 GB kit is running at DDR5-4800 CL40 after installation?

Check the BIOS memory information screen — it should report 256 GB total, 4800 MT/s data rate, and CL40 latency for each of the eight 32 GB modules.
