Exact-match 64 GB DDR5-6400 RDIMM

This 64 GB DDR5-6400 registered ECC module is built to the precise rank, voltage and timing the Gigabyte MZ73-LM0 memory controller expects. It installs as a 288-pin RDIMM so the board recognises the full capacity at its rated speed without manual tuning.

Sustained-load stability with registered ECC

The registered architecture buffers address and command signals, letting every populated slot run at 6400 MT/s continuously while ECC corrects single-bit errors on the fly. This prevents silent data corruption and unplanned reboots during long production workloads.

Straightforward 288-pin RDIMM installation

The module slots into the board's DDR5 RDIMM sockets like any standard DIMM, but population order and maximum supported capacity vary by system revision. Consult the motherboard manual for the approved slot sequence before fitting the kit.

Questions about this item

How much power does the 1.1 V DDR5 6400 RDIMM draw when the server runs continuously?

Each module operates at 1.1 V with CL52 timings; the registered design reduces electrical load on the memory controller so fully populated slots stay stable at the rated 6400 MT/s speed.

What motherboard slot and population rules does the GIGABYTE MZ73-LM0 require for this 288-pin ECC RDIMM?

The board uses 288-pin DDR5 RDIMM slots; consult the MZ73-LM0 manual for supported capacities per channel and the approved DIMM installation order before fitting the 64 GB kit.

Can I mix this 2Rx4 CL52 registered ECC module with older DDR5 RDIMMs of different rank or latency in the same server?

Mixing ranks or CAS latencies is not recommended; the memory controller expects identical 2Rx4 CL52 timings across all populated channels to run at the full 6400 MT/s data rate.
