Exact-match server kit

This 384GB kit contains six 64GB DDR5-6400 Registered ECC RDIMMs built to the precise rank, voltage and timing the GIGABYTE MZ73-LM0 memory controller expects. Each module runs at 1.1V with CL52 latency and a 2Rx4 organisation so the full capacity is recognised at rated speed.

Build integration

The 288-pin RDIMM form factor matches the board's registered DIMM slots — not UDIMM or SODIMM — and the buffered architecture offloads the controller when every slot is populated. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots in production workloads.

What the kit changes

Six matched modules ship together so population order follows the motherboard manual without mixing loose sticks. Lifetime replacement coverage and US-based technical support back the installation, while the exact-match specification removes the trial-and-error of generic memory qualification.

Questions about this item

What is the CAS latency that limits throughput under sustained load?

The kit runs at CL52, so every read cycle waits 52 clock periods before data appears on the bus.

How much power does the full 384 GB kit draw at 1.1 V?

Each module operates at 1.1 V; total draw depends on how many ranks the memory controller activates during all-day operation.

Which motherboard must already be installed for these modules to work?

The memory is validated for the GIGABYTE MZ73-LM0 motherboard with DDR5 6400 support.
