Exact-match server upgrade

This 576GB kit contains twelve 48GB DDR5 RDIMMs validated for the GIGABYTE MZ73-LM1 motherboard. Each module is a registered ECC DIMM built with major OEM chips and operates at 1.1V with CL52 latency. The kit targets administrators who need maximum registered capacity on this specific platform.

Registered DDR5 population rules

Registered architecture buffers the command bus so all twelve slots can run fully populated at the rated 6400 MT/s speed. ECC corrects single-bit errors in flight to prevent silent data corruption. The motherboard manual defines the required slot population order and any per-channel capacity limits that govern this configuration.

2Rx8 organisation at DDR5-6400

The dual-rank x8 layout determines how the memory controller addresses each DIMM and whether the board can reach full speed with every slot filled. Buyers whose systems require single-rank modules or a different data width will not be able to use this kit at its rated specification.

Questions about this item

Should I pick the 12 x 48 GB kit or a smaller capacity for my GIGABYTE MZ73-LM1?

Choose the 12 x 48 GB kit when you need the full 576 GB that the board supports; each 48 GB module is a 2Rx8 registered DIMM so every slot runs at the rated DDR5 6400 speed.

What does DDR5 6400 CL52 deliver inside the server?

The modules transfer data at 6400 MT/s with a CAS latency of 52 cycles, giving the memory controller the exact timing it expects for full-capacity operation.

How does the 288-pin RDIMM interface affect performance?

The registered 288-pin RDIMM form factor buffers address and command signals, allowing all twelve slots to run at the full 6400 MT/s data rate without signal degradation.
