  • 288-pin RDIMM form factor validated for GIGABYTE MZ73-LM0 compatibility

Exact-match server kit

This 128 GB kit delivers eight 16 GB DDR5-6400 Registered ECC RDIMMs tuned to CL52 at 1.1 V. It targets administrators upgrading a GIGABYTE MZ73-LM0 motherboard that requires 288-pin RDIMMs with 1Rx8 organisation. The modules arrive as a single matched kit so the board recognises the full population at rated speed.

Capacity and headroom

Eight slots filled provides 128 GB of registered ECC capacity, letting the memory controller drive every DIMM at DDR5-6400 without down-clocking. Workloads that exceed this total will need a platform with more slots or higher-density modules, as this kit does not offer larger densities or additional ranks.

Verified fitment and support

The kit is validated for the GIGABYTE MZ73-LM0, eliminating guesswork around population rules and voltage. Backed by lifetime replacement coverage and US-based technical support, it replaces the trial-and-error of mixing loose modules with a single qualified part number.

Questions about this item

Will this 128GB DDR5 6400 kit operate correctly if I keep some existing DDR5 modules installed?

Mixing memory kits with different speeds, latencies, or ranks can prevent the server from booting or force all modules to run at the lowest common settings. For guaranteed stability at DDR5 6400 CL52, populate all slots with this matched 8x16GB kit.

How can I verify the 1Rx8 Registered ECC modules are running at DDR5 6400 CL52 after installation?

Enter the system BIOS or UEFI and confirm the memory speed shows 6400 MT/s (PC5-51200) with CL52 timings. Registered ECC status and 1Rx8 rank should also be reported in the memory information section.

Does the package include 8 modules of 16GB each, and is anything else required for installation?

The box contains exactly eight 16GB DDR5 288-pin RDIMMs for a total of 128GB. No additional parts are included; only the motherboard's DIMM slots and a compatible system are needed.
