64GB DDR5 6400 ECC RDIMM Kit

This 64GB kit contains four 16GB DDR5 6400 registered ECC RDIMMs. It runs at 1.1V with CL52 latency and a 1Rx8 organization. The modules are built for servers and workstations that require registered memory with error correction.

Compatibility Check Before Ordering

Verify that your motherboard accepts 288-pin DDR5 RDIMMs and supports the registered ECC architecture. Check the system manual for approved DIMM population order and maximum capacity per channel. The kit is validated for the GIGABYTE MZ23-SU0 motherboard; other boards may have different population rules.

Sustained Load Behavior

Registered buffering reduces electrical load on the memory controller when all four slots are populated. ECC corrects single-bit errors during continuous operation, preventing silent data corruption. The 1.1V operating voltage helps maintain stability across extended workloads in server environments.

Questions about this item

Does the 64GB kit contain four 16GB modules or are extra DIMMs required?

The kit ships with four 16GB DDR5 RDIMMs for a total of 64GB, so no additional modules are needed to reach that capacity.

When should I choose the CL52 1.1V 1Rx8 version over other DDR5 ECC RDIMM options?

Select this version when your GIGABYTE MZ23-SU0 motherboard requires registered 288-pin DDR5 6400 memory with exactly those timings, voltage and rank.

Will the rated 6400 MT/s speed be active once the kit is installed in the MZ23-SU0?

Yes, the modules are spec-matched to the board's memory controller, so the full 6400 MT/s transfer rate is recognised and used when all four slots are populated.
