768GB DDR5 5600 ECC RDIMM kit

This 768GB kit contains sixteen 48GB DDR5 5600 registered DIMMs with ECC and a CAS latency of 46. Each module operates at 1.1V and uses a 2Rx8 organisation on a 288-pin form factor. The memory is built for server platforms that require registered error-correcting modules.

Sustained load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller, allowing all sixteen modules to run at the rated 5600 speed under continuous workloads. ECC corrects single-bit errors and detects multi-bit errors, preserving data integrity during long compute runs. The 1.1V operating voltage helps maintain thermal stability across fully populated channels.

Upgrade from lower-capacity DDR5 RDIMMs

Replacing smaller DDR5 registered kits with this 768GB configuration increases the addressable memory for virtualisation hosts, in-memory databases and large-scale simulation nodes. The jump is worthwhile when the application working set exceeds the capacity of existing modules and the platform supports sixteen 2Rx8 registered DIMMs at 5600. Not for desktop or workstation boards that accept only unbuffered memory.

Questions about this item

How much power does the 768GB kit draw at 1.1V during continuous operation?

Each 48GB module runs at 1.1V; total draw depends on the platform's memory controller and how many ranks are active.

What motherboard feature is required to use these registered ECC modules?

The board must support DDR5 RDIMM with ECC and provide 16 288-pin slots for the full kit.

Can the 2Rx8 organisation run alongside 1Rx8 DDR5 DIMMs in the same server?

Mixing ranks is platform-dependent; check the system's qualified vendor list for supported rank combinations.
