Dell Latitude 5440 Upgrade Guide: RAM and SSD Options

Updated Oct. 9, 2026 · Written from this device's verified specifications

This guide covers the memory and SSD upgrades available on the Dell Latitude 5440. The short answer: you can fit up to 64 GB of RAM in two SO-DIMM slots, but you must match the memory generation your unit shipped with. Storage is a single M.2 2230 NVMe slot, so a bigger SSD means replacing the existing drive.

At a glance

  • RAM: 2 SO-DIMM slots, up to 32 GB each and 64 GB total, non-ECC only.
  • Your unit uses either DDR4-3200 or DDR5, and the two can't be mixed.
  • Storage: one M.2 2230 NVMe slot (PCIe Gen4 x4), up to 2 TB, and no second SSD slot or 2.5-inch bay.
  • The Wi-Fi and optional WWAN M.2 slots are for wireless cards, not storage.
  • No CPU upgrade is listed for this model.

RAM: two SO-DIMM slots, up to 64 GB

The Latitude 5440 has two SO-DIMM slots and no soldered memory is mentioned in Dell's documents. Dell lists 8, 16 or 32 GB modules, so the most you can install is 2 x 32 GB for 64 GB total. The minimum configuration is 8 GB. Memory is non-ECC only.

Each unit ships with either DDR4-3200 or DDR5, and you can't mix generations. Check which type yours has before you buy. Dell's manuals disagree slightly on DDR5 speed: the earlier manual and the system guide list DDR5-4800, while the newer manual adds DDR5-5200. Either way, the fastest DDR4 listed is 3200 MT/s.

Dell lists both single- and dual-channel configurations. Fitting two matching modules is the usual way to get dual-channel. As an example, one retailer listing for an i5-1345U model shows DDR4-3200 as 2 x 8 GB. Treat that as typical rather than guaranteed, because specs vary by variant.

Buying tips

  • Confirm whether your unit has DDR4 or DDR5 before buying, for example from the service tag configuration on Dell's support site.
  • Buy SO-DIMM modules (laptop size), not desktop DIMMs.
  • Choose non-ECC, unbuffered modules.
  • For the most memory, buy a matched pair of 32 GB modules.
  • Don't buy DDR5 for a DDR4 unit, or the reverse.

Storage: one M.2 2230 NVMe slot, up to 2 TB

The Latitude 5440 has one SSD slot. It takes an M.2 2230 NVMe drive (PCIe Gen4 x4) up to 2 TB. Dell doesn't list a SATA option, a second M.2 SSD socket or a 2.5-inch drive bay. Upgrading therefore means replacing the one drive you have, so plan to move your data across or reinstall.

The SSD sits under a thermal shield held by two M2x3 screws. Keep track of those screws and refit the shield afterwards.

Don't confuse the other M.2 slots with storage. The M.2 2230 slot for Wi-Fi/Bluetooth and the optional M.2 3042/3052 slot for a WWAN card are for wireless cards only.

Buying tips

  • Look specifically for M.2 2230 NVMe drives. Longer 2280 drives won't fit.
  • 2230 drives have fewer retail options than 2280, so check availability at your target capacity before you commit.
  • Don't buy a SATA M.2 drive, as the slot is listed as NVMe only.
  • Don't count on a memory card slot for extra storage. No SD or microSD slot was confirmed, only a smart card reader or generic card reader.

How to upgrade

Before you start

  • Confirm whether your unit has DDR4 or DDR5 memory before you buy RAM.
  • Check your unit's exact configuration against Dell's support page for your service tag, as specs vary by variant.
  • Back up your files, or plan to clone the old SSD, before swapping the drive.
  • Have the owner's manual open for exact disassembly steps.
  • Don't use the specs for Dell's Inspiron 14 5440. It is a different laptop with different memory limits.
  • You'll need a small screwdriver for the base screws and the two M2x3 SSD shield screws.

Steps

  1. Back up your data
    Copy important files to an external drive or cloud storage. If you're replacing the SSD, decide whether you'll clone the old drive or reinstall Windows.
  2. Power off and unplug
    Shut the laptop down fully (not sleep), unplug the charger and disconnect any accessories.
  3. Ground yourself
    Work on a clean, flat surface and touch bare metal before handling components to discharge static. Hold memory modules and SSDs by their edges.
  4. Open the case
    Follow Dell's owner's manual to remove the base cover, including any battery precautions it describes. Keep the screws organised.
  5. Replace the RAM
    To remove a module, spread the securing clips until it pops up, then slide it out. Slide the new module in and press it down until the clips lock. Use matching DDR4 or DDR5 modules, never a mix.
  6. Replace the SSD
    Remove the two M2x3 screws holding the thermal shield and lift the shield off. Swap in the new M.2 2230 NVMe drive, then refit the shield and screws.
  7. Close up
    Refit the base cover and screws, then reconnect the charger.
  8. Check that the system sees the new part
    Start the laptop and open the BIOS setup screen to confirm the new memory total or SSD is detected. If it isn't, power off and recheck that the part is seated properly. Then install or restore your operating system if you replaced the drive.

Good to know

  • Dell's manuals disagree on DDR5 speed: some list DDR5-4800 only, while the newer manual adds DDR5-5200.
  • Specs vary by variant, so confirm your unit's configuration with Dell using your service tag.
  • No SD or microSD slot was confirmed. Only a smart card reader or generic card reader is listed, so check your unit's ports.
  • The PDF manual's storage table is hard to read, and one entry for an M.2 3042 slot appears to describe WWAN options rather than the SSD.
  • Dell's Inspiron 14 5440 is a different laptop. Don't use its memory limits for the Latitude 5440.

Frequently asked questions

How much RAM can the Dell Latitude 5440 take?

Up to 64 GB, using two 32 GB SO-DIMMs. The minimum configuration is 8 GB, and only non-ECC memory is supported.

Does the Latitude 5440 use DDR4 or DDR5?

It depends on the unit. Dell lists both DDR4-3200 and DDR5 (4800, with 5200 in the newer manual). Check which one yours has and don't mix them.

Can I add a second SSD to the Latitude 5440?

No. There is one M.2 2230 NVMe slot, no second SSD socket and no 2.5-inch bay. To get more storage, replace the existing drive.

What size SSD does the Latitude 5440 take?

An M.2 2230 NVMe drive (PCIe Gen4 x4), up to 2 TB. Longer 2280 drives won't fit.

Can I use the Wi-Fi or WWAN slot for an SSD?

No. The M.2 2230 Wi-Fi slot and the optional M.2 3042/3052 WWAN slot are for wireless cards only.

Can I upgrade the CPU in the Latitude 5440?

Dell's documents don't list a CPU upgrade for this laptop, so the practical upgrades are RAM and the SSD. Dell's system guide covers both 12th- and 13th-generation Core CPUs, depending on the variant.
