32 GB DDR5 ECC Registered RDIMM

This 32 GB DDR5 5600 module uses a 288-pin RDIMM form factor with CL46 latency and 1.1 V operation. It is built for workstations and servers that require registered ECC memory. The single rank 2Rx4 configuration provides 32 GB per stick.

Check motherboard DDR5 RDIMM support

Verify that your system accepts DDR5 registered ECC RDIMMs and cannot mix them with unbuffered or load-reduced modules. Confirm the platform supports 5600 MT/s speed and 1.1 V voltage. All DIMMs should match capacity, speed and manufacturer for optimal performance.

Suits server and workstation upgrades needing

Ideal for extending older infrastructure or building new servers that require JEDEC-standard registered ECC memory. Not suitable for standard desktop computers that use unbuffered non-ECC modules. Buyers needing load-reduced ECC or consumer desktop memory should look elsewhere.

Questions about this item

Does the 32GB DDR5 5600 CL46 ECC Registered RDIMM come alone or with extra parts?

The module ships as a single 32GB stick. No heat spreader, cables or additional components are included.

When should I choose this 32GB 2Rx4 CL46 module over another capacity or rank?

Pick this 32GB 2Rx4 CL46 kit when your workstation or server requires registered ECC DDR5 at 5600 MT/s and the memory slots support 2Rx4 organisation.

What does the 5600 MT/s rating deliver once the DIMM is installed in a compatible server?

The module runs at the JEDEC-standard 5600 MT/s (PC5-44800) with CL46 latency at 1.1 V, providing registered ECC bandwidth for supported platforms.
