OWC 8GB DDR4 2133MHz CL15 1.2V 288pin UDIMM Dell Precision 3420

Precision 3420 Memory Upgrade

This 8 GB DDR4 module is built for the Dell Precision 3420 workstation. It runs at 2133 MHz with CL15 latency and 1.2 V operation. The unbuffered, non-ECC UDIMM targets professionals who need more capacity for multitasking or larger datasets.

Replacing Slower or Smaller DIMMs

The jump is worth it when the system ships with 4 GB sticks or runs at a lower clock. Swapping to this 288-pin PC4-17000 module restores the platform's rated bandwidth without changing voltage. It does not suit builds that require registered or ECC memory.

Tool-Free Slot Installation

The DIMM drops into the standard UDIMM slots on the Precision 3420 motherboard; no drivers or firmware updates are needed. The most common issue is mixing ranks or speeds across channels, which can force the whole array down to the slowest setting. Populate identical modules per channel for stable operation.
