  • DDR5 5600 speed delivers high bandwidth for workloads
  • 1 V operation reduces power draw per module
  • JEDEC standard compliance ensures broad platform compatibility

ECC Registered DDR5 Kit

This 32 GB kit contains two 16 GB DDR5 5600 modules built to JEDEC PC5-44800 CL46 specifications. Registered ECC design targets workstations and servers that require error correction and signal buffering. It will not function in standard desktop platforms or alongside unbuffered or load-reduced DIMMs.

1Rx8 Capacity and Headroom

Dual-rank 1Rx8 organisation delivers 32 GB across two channels, letting memory-intensive workloads scale within registered memory limits. CL46 latency at 5600 MT/s provides stable throughput for virtualisation and database tasks, while the 1.1 V operating voltage keeps power draw predictable. Workloads exceeding 32 GB per channel will require additional registered DIMM slots.

288-Pin Registered Build Fit

Modules use the standard 288-pin DDR5 RDIMM form factor and require a motherboard with registered ECC support and dual-channel architecture. No heat spreader is fitted, so airflow in the memory zone must be managed by the chassis. Mixing with unbuffered or load-reduced memory is not supported, so all populated slots must match this registered specification.

Questions about this item

Will this DDR5 5600 ECC registered kit run alongside existing DDR5 4800 registered modules in my server?

Mixing different DDR5 speeds forces the system to run all memory at the lowest common speed, so 5600 modules will downclock to match 4800 modules if they share a channel.

How can I confirm the kit is operating at 5600 MT/s with CL46 after installation?

Check the memory speed and timings in the BIOS/UEFI setup or use a system-information tool such as CPU-Z to verify DDR5 5600 and CL46 are reported.

Does the 32 GB dual-channel kit include a heat spreader or any extra accessories?

The kit contains only the two 16 GB 288-pin DDR5 5600 CL46 1Rx8 ECC registered RDIMM modules; no heat spreader or additional accessories are included.
