Targeted Server Upgrade

This 512GB kit delivers four 128GB DDR5 RDIMMs built for the GIGABYTE MS04-CE0 motherboard. Registered ECC architecture ensures each module is recognised at full capacity and runs at the rated 6400MHz speed. It is intended for administrators who need maximum supported memory in a validated configuration. Builders using consumer boards or unbuffered DIMM slots cannot use this kit.

Capacity and Headroom

Four dual-rank modules provide 512GB of addressable memory for multi-socket workloads, virtualization density and large in-memory databases. The registered buffer allows every slot to stay fully populated without signal degradation. Workloads that exceed 512GB or require higher clock rates than 6400MHz will need a platform with greater memory-controller limits.

Thermals and Power

Bare modules operate at 1.1V with no heat spreaders, relying on chassis airflow for cooling. Power draw scales linearly with all four DIMMs active at 6400MHz, so adequate case ventilation is required to keep temperatures in spec. Acoustic output is determined entirely by the server fans, not the memory itself.

Questions about this item

Will this 4-module 512GB DDR5-6400 kit work alongside any existing RDIMMs I keep in the GIGABYTE MS04-CE0?

The kit is validated for the GIGABYTE MS04-CE0 at DDR5-6400 with 2Rx4 registered ECC at 1.1V. Mixing ranks or voltages can prevent full-speed operation, so populate all slots with identical modules or follow the board's population rules.

How can I confirm the kit is running at 6400 MT/s with CL52 after installation?

Enter the BIOS or use a hardware-info utility and verify the memory frequency reads 6400 MT/s (PC5-51200) and the CAS latency shows 52. Registered ECC status should also be reported as active.

What exactly ships in the box and is anything else required?

The box contains the 512GB kit as four 128GB 288-pin DDR5 RDIMMs. No heat spreaders, cables or additional parts are included; the motherboard and a compatible CPU are all that is needed.
