OWC 16GB DDR4 2133MHz CL15 1.2V 288-pin UDIMM for Dell Precision 3420

16GB DDR4 UDIMM for Dell Precision 3420

This 16GB DDR4 2133MHz CL15 module is built for the Dell Precision 3420 workstation. It uses a 288-pin unbuffered non-ECC design at 1.2V. The 2Rx8 rank configuration matches the platform's native memory architecture.

Check your Precision 3420 memory slots

Verify how many of the four UDIMM slots are free and the total installed memory before ordering. The system requires DDR4 2133MHz non-ECC unbuffered modules; mixing ECC or registered DIMMs will prevent boot. Confirm the existing sticks are also 1.2V CL15 for best stability.

Replaces slower or smaller DDR4 sticks in the same

Swapping 8GB or lower-density modules for this 16GB kit raises the memory ceiling for larger datasets and concurrent applications. The jump is worth it when the workstation hits the current RAM limit during rendering, virtualization or heavy multitasking.
