OWC 4GB DDR4 2133MHz CL15 1.2V 288-pin UDIMM Dell Precision 3420

Dell Precision 3420 memory upgrade

This 4 GB DDR4 module is built specifically for the Dell Precision 3420 workstation. It installs as a standard 288-pin UDIMM and requires no configuration changes. The part is new and covered by the manufacturer's limited lifetime warranty.

Speed and latency match the platform

The stick runs at 2133 MHz with a CAS latency of CL15, matching the PC4-17000 specification the system expects. Using a different speed or latency can prevent boot or force the memory controller to downclock.

Low-voltage unbuffered design

At 1.2 V the module draws minimal power and generates little heat, so the workstation's existing cooling handles it without extra noise. The unbuffered, non-ECC layout keeps the electrical load light on the memory controller.
