256GB DDR5 5600 ECC RDIMM kit

This 256GB kit contains sixteen 16GB registered DIMMs built for DDR5 5600 platforms that require error-correcting memory. It targets server administrators upgrading multi-socket systems with 288-pin registered slots. The modules are not compatible with standard desktop or laptop motherboards.

Sustained load behaviour

Registered buffering and on-die ECC maintain data integrity during continuous operation in virtualization, database or compute clusters. The 1.1V operating voltage keeps power draw predictable across all sixteen modules under full population. CAS latency of 46 applies at the rated 5600 MT/s transfer rate.

1Rx8 registered ECC constraint

Each module uses a single-rank 1Rx8 organisation with registered signalling, so the platform memory controller must support registered ECC RDIMMs at DDR5 5600. Systems limited to unbuffered UDIMMs or lower speeds cannot use this kit.

Questions about this item

How much power do the 1.1V DDR5 5600MHz RDIMMs draw when the server runs all day?

Each module operates at 1.1V; total power depends on the platform's memory controller and load, not on a fixed per-stick wattage figure.

What motherboard feature must I already have to use this 288-pin ECC RDIMM kit?

A server board with DDR5 RDIMM slots that supports 5600MHz registered ECC memory and can address 256GB across 16 slots.

Can I mix these 1Rx8 registered modules with older DDR5 RDIMMs of a different rank or speed in the same system?

Mixing ranks or speeds is not recommended; the memory controller will typically down-clock all channels to the slowest module and may require identical rank configuration per channel.
