  • 128 GB total capacity from eight 16 GB modules for high-density server workloads
  • DDR5 4800 speed with CL40 latency delivers rated throughput for the platform
  • Registered ECC architecture offloads the controller and corrects single-bit errors on the fly
  • 1 V operation at 1Rx8 rank matches the motherboard's memory-controller expectations
  • 288-pin RDIMM form factor fits the GIGABYTE MZ73-LM0 board's DIMM slots exactly

Exact-match server kit

This 128GB kit provides eight 16GB DDR5 RDIMMs rated at 4800MHz PC5-38400 with CL40 latency and 1.1V operation. It is built for the GIGABYTE MZ73-LM0 motherboard and uses the registered ECC architecture that board requires.

Capacity and headroom

Eight populated slots deliver 128GB of registered ECC memory, giving each channel the rank density the platform expects for full-speed operation. The 1Rx8 organization and registered buffer let the memory controller drive all slots at the rated 4800MHz without down-clocking.

Build integration

The 288-pin RDIMM form factor fits only DDR5 registered DIMM slots; it will not work in UDIMM or SODIMM sockets. ECC and registered buffering offload the memory controller and correct single-bit errors, freeing the system from silent data corruption during sustained workloads.

Questions about this item

Will this DDR5 4800 CL40 RDIMM kit run alongside my existing DDR5 4800 modules?

The kit uses 1.10 V, CL40 timing and 1Rx8 registered ECC; matching those specs on the installed DIMMs gives the best chance of stable operation.

How can I verify the 128 GB kit is detected at DDR5 4800 with ECC active?

Enter the motherboard firmware and check that all eight slots show 16 GB each at 4800 MT/s with ECC status enabled.

Does the 8x16 GB package include a heat spreader or any cables I need to buy separately?

The modules have no heat spreader and the box contains only the eight RDIMMs; no extra cables or brackets are required.
