Capacity and purpose

This 256 GB kit provides four 64 GB DDR5-6400 Registered ECC RDIMMs built for the GIGABYTE MS04-CE0 motherboard. It targets server administrators who need maximum supported capacity with error correction and registered buffering for stable, full-population operation.

Form factor and fit

Each module uses the 288-pin RDIMM form factor required by the board, so it cannot be used in UDIMM or SODIMM slots. The exact rank, voltage and timing match the controller expectations, ensuring recognition at full capacity and rated speed when installed per the motherboard population rules.

Thermals and power

Modules run at 1.1 V without heat spreaders, relying on chassis airflow for cooling in typical server environments. Registered architecture reduces electrical load on the memory controller, while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

Questions about this item

What speed does the DDR5 6400 interface actually run at when all four slots are populated?

The kit is rated for DDR5 6400 (PC5-51200) and the registered design lets every slot run at that speed when fully populated.

Will these 288-pin RDIMMs fit the GIGABYTE MS04-CE0 motherboard?

Yes, the 288-pin registered RDIMM form factor matches exactly what the MS04-CE0 requires — no UDIMM or SODIMM will work.

What population order should I follow when installing the four 64 GB modules?

Check the motherboard manual for the approved DIMM population sequence before seating all four sticks.
