The Dell Latitude 5400 supports up to 32 GB of RAM in two SO-DIMM slots, using a 2 × 16 GB configuration. Dell specifies dual-channel DDR4 memory rated at 2666 MHz; with an Intel 8th Gen processor, it operates at 2400 MHz. Check your processor and installed memory before choosing an upgrade.
Dell Latitude 5400 RAM specifications
| Specification | Dell’s documented support |
|---|---|
| Memory slots | 2 SO-DIMM slots |
| Maximum capacity | 32 GB total, up to 16 GB per slot |
| Memory type | Dual-channel DDR4 |
| Listed memory speed | 2666 MHz; operates at 2400 MHz with Intel 8th Gen processors |
| Documented capacity range | Configurations begin at 4 GB (1 × 4 GB) and extend to 32 GB (2 × 16 GB) |
These are the configurations in Dell’s Latitude 5400 Setup and specifications guide. The processor caveat matters: do not assume the memory will run at 2666 MHz in every Latitude 5400.
What RAM should you buy?
For the documented maximum, look for a 32 GB DDR4 SO-DIMM kit made up of two 16 GB modules. A vendor compatibility sheet lists a kit with two 16 GB, 2666 MHz, 260-pin DDR4 SO-DIMMs, which corroborates that product format; Dell’s supported configurations remain the authority for the laptop’s limits. This is not a Dell endorsement or a test of a particular kit.
Before ordering, confirm the laptop’s current memory configuration and processor. Dell documents both one-module and paired configurations, so the guide does not establish that only matched pairs work. A two-module kit is simply the direct route to the specified 32 GB maximum.

How to check your current configuration
- In Windows, open Settings > System > About and note the installed RAM and processor information.
- Compare those details with Dell’s specifications and the memory modules currently installed. In particular, determine whether one or both slots are occupied before choosing a capacity and kit.
- Use the processor model to interpret the speed: Dell lists 2666 MHz memory, with operation at 2400 MHz for Intel 8th Gen processors.
Installing or replacing Latitude 5400 memory
Use Dell’s Latitude 5400 service-manual section for memory modules for the model-specific removal and installation procedure. The Dell manuals listing provides access to the model’s documentation. An independent iFixit Latitude 5400 RAM replacement guide also exists. Follow the full procedure for your laptop rather than relying on generic installation steps.
