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.

Points forts

Questions sur cet article

Will this 288pin DDR4 UDIMM fit the Dell Precision 3420 memory slots?

Yes, the 288pin DDR4 UDIMM form factor matches the Dell Precision 3420 DIMM slots exactly.

What is the correct way to seat this 8GB module so the system recognises the full capacity?

Align the notch with the slot key, press firmly until both side clips click, then verify 8GB appears in BIOS.

Does the CL15 1.2V specification mean I will need to adjust voltage or replace the module sooner?

No, CL15 at 1.2V follows JEDEC standard timings and requires no voltage changes or early replacement.
