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.

Questions about this item

What comes in the box and do I need any extra parts to install the 16GB DDR4 2133MHz UDIMM in a Dell Precision 3420?

The module ships as a single 288-pin DDR4 UDIMM. No additional components are required; it installs directly into an available DIMM slot on the Precision 3420 motherboard.

How do I decide between the CL15 2133MHz version and any other speed or latency options for this system?

The Dell Precision 3420 officially supports DDR4 2133MHz memory. This CL15 module matches that specification, so selecting it ensures full compatibility without needing to adjust BIOS settings.

What does the PC4-17000 2133MHz rating actually deliver once the DIMM is running in the workstation?

PC4-17000 denotes a peak transfer rate of 17000 MB/s at 2133MHz. In the Precision 3420 the module operates at that speed with CL15 latency, providing the bandwidth and responsiveness the platform was designed for.
