32GB DDR5 5600 ECC RDIMM

This 32GB DDR5 5600 module is an ECC Registered RDIMM designed for select workstations and servers. It operates at 1.1V with CL46 latency and a 2Rx8 rank configuration. The 288-pin form factor fits compatible DDR5 server platforms. It is not suitable for standard desktop computers or consumer motherboards.

ECC Registered stability

Error-correcting code and registered buffering protect data integrity in multi-DIMM server configurations. JEDEC and RoHS compliance ensures the module meets industry specifications for warranty-safe upgrades. The single 32GB stick allows capacity expansion in matched sets. Mixing with unbuffered or load-reduced memory is not supported.

Verify platform compatibility

Confirm the workstation or server accepts DDR5 5600 ECC Registered RDIMMs before ordering. The system must support 2Rx8 organisation and 1.1V operation. Existing memory should match capacity, speed and manufacturer for optimal performance. This module will not function in desktop boards or with unbuffered memory types.

Questions about this item

Will the 32GB DDR5 5600 CL46 registered DIMM need any maintenance or component replacement over its service life?

The module has no heat spreader and no moving parts, so no scheduled maintenance is required; replacement is only needed if a memory error appears or capacity must be increased.

What limit appears first when the 32GB DDR5 5600 CL46 registered DIMM runs continuously at full load?

Sustained throughput is capped by the DDR5 5600 data rate and CL46 latency, so memory bandwidth becomes the bottleneck before thermal or power limits.

How much noise, heat and power does the 32GB DDR5 5600 CL46 registered DIMM produce when running all day?

The module operates silently at 1.1 V with no fan or heat spreader, so it adds negligible noise and only modest heat to the server chassis.
