Compatible Dell PowerVault NX400 Upgrade

This 32GB kit contains four 8GB DDR3L 1600 registered ECC modules built for the Dell PowerVault NX400. It targets server and workstation administrators who need error-correcting memory for data integrity in storage or virtualization workloads.

Straightforward 240-Pin Installation

Each RDIMM fits the 240-pin DDR3L slots in the NX400 without tools. The modules are registered and use 1Rx4 organization, so they must not be mixed with unbuffered DIMMs; doing so prevents the system from posting.

Steady Operation at 1.35V

The low-voltage DDR3L parts run at 1.35V and CL11 latency, reducing heat during continuous server duty. ECC registration corrects single-bit errors on the fly, helping the NX400 maintain uptime through extended backup or replication jobs.
