32GB DDR5 ECC RDIMM for Servers

This 32GB DDR5 5200 module is built for workstations and servers that require registered ECC memory. It operates at 1.1V with a CL42 latency and a 2Rx4 rank configuration. The 288-pin RDIMM form factor fits compatible server platforms only.

Suits registered ECC platforms only

It suits administrators upgrading compatible workstations, NAS systems or network switches that explicitly support DDR5 registered ECC DIMMs. Builders using standard desktop motherboards or consumer laptops cannot use this module. Systems requiring load-reduced or unbuffered memory should look elsewhere.

Registered ECC is the deciding spec

The module is a registered ECC DDR5 RDIMM, so the motherboard must support registered error-correcting memory. Unbuffered or load-reduced slots will not accept it. Verify the platform documentation before purchase.
