Exact-match server upgrade

This 256GB kit contains eight 32GB DDR5 RDIMM modules rated at 6400MHz PC5-51200 with CL52 latency and 1.1V operation. It is built specifically for the GIGABYTE MZ73-LM1 motherboard and uses registered ECC architecture with 2Rx8 organisation.

Slot-aligned installation

The 288-pin RDIMM form factor matches the board's required slot type; UDIMM or SODIMM modules will not fit. Follow the motherboard manual for the approved population order when filling all eight slots to ensure the system recognises the full capacity at rated speed.

DDR5 registered ECC limits

Registered buffering reduces electrical load on the memory controller, allowing full population at the rated 6400MHz, while ECC corrects single-bit errors to prevent silent data corruption. The kit is validated for this specific platform; other servers or boards may impose different population rules or maximum capacities not covered here.

Questions about this item

How do I confirm the 256GB kit is running at DDR5 6400 CL52 after installation?

Enter the BIOS or UEFI and verify the memory frequency reads 6400 MT/s with CAS latency 52; the registered ECC modules will also report corrected error counts if ECC is active.

What comes in the 8x32GB package and what must I source separately?

The box contains eight 32GB 288-pin DDR5 RDIMMs totalling 256GB; no cables, brackets or cooling accessories are included and none are required for standard server DIMM slots.

Which capacity version should I choose for a fully populated GIGABYTE MZ73-LM1?

This 256GB kit provides eight 32GB 2Rx8 modules, matching the board's maximum supported DIMM count and rank configuration for full-capacity operation.
