Server-grade DDR4 ECC RDIMM

This 32GB DDR4 2133MHz PC4-17000 ECC Registered RDIMM is built for servers, workstations and NAS systems that require registered memory with error correction. It operates at 1.2V with CL15 latency and a 2Rx4 rank configuration. The module replaces Dell part numbers A8217683, A8423729 and SNPPR5D1C/32G.

288-pin registered form factor

The 288-pin DDR4 RDIMM fits only platforms that support registered ECC memory and cannot be mixed with unbuffered modules. No heat spreader is fitted, so airflow in the chassis handles cooling. JEDEC and RoHS compliance ensures a warranty-safe upgrade for qualified systems.

DDR4 2133 registered limits

Registered ECC DDR4 at 2133MHz is bound by the JEDEC PC4-17000 standard and will not function in standard desktop motherboards that accept only unbuffered memory. Mixing registered and unbuffered DIMMs is not supported, and the module cannot be used in consumer platforms lacking registered memory controllers.
