Exact-fit DDR5 kit for GIGABYTE MZ73-LM1

This 384 GB kit contains six 64 GB DDR5 6400 RDIMMs built to the exact rank, voltage and timing the MZ73-LM1 memory controller expects. It is intended for administrators upgrading that specific server platform to its maximum supported capacity.

Registered ECC design and 288-pin form factor

Registered buffering reduces electrical load on the controller so all six slots can run fully populated at rated speed, while on-die ECC corrects single-bit errors before they reach the OS. The 288-pin RDIMM form factor matches the board's DIMM sockets; UDIMM or SODIMM modules will not fit.

DDR5-6400 speed ceiling and population rules

The modules operate at DDR5 6400 (PC5 51200) with CL52 latency at 1.1 V, which is the highest JEDEC speed this platform specifies. Supported capacities and required slot-population order are defined by the motherboard manual, so verify that document before installation.

Questions about this item

What DDR5 speed and PC5 rating does this 384GB kit run at?

The kit operates at DDR5 6400 with a PC5-51200 data rate, the exact speed the GIGABYTE MZ73-LM1 memory controller expects for full-capacity operation.

What physical form factor and pin count must the motherboard slots accept?

Each module is a 288-pin Registered RDIMM; the board must provide 288-pin DDR5 RDIMM slots — UDIMM or SODIMM sockets will not fit.

How should the six 2Rx4 modules be populated, and what step is often missed?

Follow the GIGABYTE MZ73-LM1 manual for the approved DIMM population order; the step most often missed is verifying the exact slot sequence before inserting all six modules.
