OWC 16GB DDR4 3200 CL22 ECC Registered RDIMM for Dell PowerVault NX3240

16GB ECC Registered DDR4 for Dell PowerVault

This 16GB DDR4 3200MHz CL22 registered DIMM is built for the Dell PowerVault NX3240 storage server. It delivers 288-pin ECC RDIMM memory with 2Rx8 organisation and 1.2V operation. The module replaces Dell part numbers AA783421, AA799064, AA810826, AB214251, M04W6 and SNPM04W6C variants. It is not compatible with standard desktop computers or unbuffered memory configurations.

Sustained server workloads with error correction

Registered buffering reduces electrical load on the memory controller during continuous operation, while ECC detects and corrects single-bit errors in real time. JEDEC-compliant 3200MHz timing at CL22 provides stable throughput for storage-intensive tasks. The 1.2V DDR4 voltage maintains consistent power draw under extended duty cycles. OWC lab testing verifies each module meets server-grade reliability standards.

ECC Registered RDIMM — not for desktops

The single specification that decides fit is the registered ECC RDIMM form factor with 288-pin DDR4 interface. This memory will only function in systems that explicitly support registered ECC modules, such as the Dell PowerVault NX3240. Builders needing unbuffered non-ECC DIMMs for workstations or consumer motherboards cannot use this part. Mixing with unbuffered memory is not supported.
