HP ProBook 450 G10 Upgrade Guide: RAM, SSD and CPU

Updated Oct. 10, 2026 · Written from this device's verified specifications

This guide covers upgrading memory and storage in the HP ProBook 450 15.6 inch G10 (also called the ProBook 450 G10), and what to expect from the processor. The short answer: you can add RAM up to 32 GB and fit an M.2 NVMe SSD, but the CPU is very likely soldered and not upgradable.

At a glance

  • RAM: 2 DDR4 SO-DIMM slots, up to 32 GB total (2 x 16 GB), DDR4-3200, non-ECC.
  • Storage: M.2 NVMe SSDs only; no SATA, 2.5 inch bay or optical drive is listed.
  • A second M.2 slot is an option and may not be present on every unit.
  • CPU: 13th-gen Intel U/P-series; almost certainly soldered, but this is not confirmed in HP's documents.
  • HP recommends HP-branded memory.

RAM: two DDR4 SO-DIMM slots, up to 32 GB

The ProBook 450 G10 has two DDR4 SO-DIMM slots. It takes standard laptop-size DDR4 (not full-size DIMMs and not DDR5). The maximum is 32 GB, as 2 x 16 GB, and the memory runs at up to DDR4-3200. No soldered memory is mentioned, so both slots should be available for upgrades.

When both slots hold matching modules, the memory runs in dual channel. Many models ship with a single module (for example 1 x 8 GB or 1 x 16 GB), which runs single-channel until you add a matching second module. HP's documents don't state a per-module limit; 16 GB per module is our reading of the 2 x 16 GB maximum.

The memory is non-ECC, and ECC is not supported. HP recommends HP-branded memory because some third-party modules are non-standard. If you mix speeds, the system runs at the lower speed.

Buying tips

  • Buy non-ECC DDR4-3200 SO-DIMMs.
  • For the best performance, fit two identical modules, such as 2 x 16 GB for the 32 GB maximum.
  • Check which module your laptop already has before buying a second one, and match its size and speed.
  • Don't buy DDR5 or full-size desktop DIMMs; neither will fit.
  • If you choose non-HP memory, buy from a seller with an easy returns policy.

Storage: M.2 NVMe only, one or two slots

Storage in this laptop is M.2 NVMe. No SATA drive, 2.5 inch bay or optical drive is listed, so a SATA SSD or a hard drive won't fit. The primary M.2 slot is standard on every unit. HP's factory SSDs run from 128 GB to 1 TB, and the 1 TB option is PCIe Gen4 x4. The smaller Value drives are listed only as PCIe NVMe, with speeds that suggest Gen3-class performance.

HP's factory SSD specifications show both 2230 and 2280 lengths, but they don't say which slot takes which length. No maximum capacity is documented for the slots. The largest factory setup is a 1 TB primary drive plus a 256 GB secondary drive, about 1.25 TB in total.

A second M.2 NVMe slot is offered as an option, with 128 GB or 256 GB Value drives. It may not be present or populated on every unit, and its supported length and PCIe speed are not documented. Check HP's maintenance guide for your exact part number before buying.

Buying tips

  • Choose an M.2 NVMe SSD, not an M.2 SATA drive.
  • The 2280 length is the safer choice for the primary slot, since the 512 GB and 1 TB factory drives use it. Confirm in HP's maintenance guide.
  • A Gen4 drive is only certain to be supported in the primary slot, where the factory 1 TB drive is Gen4 x4. A Gen3 drive is a safe, cheaper alternative.
  • Open the laptop and look for a second M.2 slot before planning a two-drive setup.
  • Check whether a screw or bracket is needed for your drive length.

How to upgrade

Before you start

  • Find your exact model and part number on the label under the laptop, since options vary by region and configuration.
  • Back up your files, and have your Windows recovery options ready if you plan to replace the system drive.
  • Get HP's maintenance and service guide or the owner's manual for the exact disassembly steps.
  • Work on a clean, flat surface with a small screwdriver set and an anti-static wrist strap if you have one.
  • Buy the right parts first: non-ECC DDR4 SO-DIMM for memory and M.2 NVMe for storage.

Steps

  1. Back up your data
    Copy important files to an external drive or cloud storage. If you are replacing the system SSD, also prepare a way to reinstall or clone Windows.
  2. Power off and unplug
    Shut the laptop down fully (not sleep or hibernate), unplug the charger and disconnect any accessories.
  3. Ground yourself
    Touch bare metal or wear an anti-static strap before handling parts, and hold memory modules and SSDs by their edges.
  4. Open the case
    Follow the disassembly steps in HP's maintenance guide or the owner's manual for removing the bottom cover. Disconnect the battery if the guide says to, and keep screws sorted by location.
  5. Install the RAM or SSD
    For memory, seat each SO-DIMM firmly at an angle in the slot and press it down until it clicks into place. For an SSD, insert it into the M.2 slot at an angle and secure it with the screw or bracket the guide describes. Fit memory in matching pairs for dual channel.
  6. Close the case and reconnect
    Refit the cover and screws, then reconnect the charger.
  7. Check that the laptop sees the new part
    Start the laptop and open the BIOS or firmware setup screen to confirm the memory size and the new drive appear. Then check in Windows. A new blank SSD will need initialising or an operating system installed.

Good to know

  • HP's documents describe factory configurations and are not a service manual. They don't say which M.2 slot takes which length or how the slots are wired.
  • The CPU being soldered is our inference from the type of processor; HP's documents don't state it either way.
  • Options vary by region and unit. For example, one regional sheet lists only 256 GB and 512 GB SSDs, and the 1 TB option's footnote suggests it may be sold only in certain regions.
  • The processor lineup differs between sheets. One lists the Core i5-1334U, which HP's support page leaves out, and the support page lists the i5-1345U, which the other leaves out.
  • We could not confirm whether this model has a memory card reader. Check HP's full specification page for your unit.
  • HP recommends HP-branded memory. Third-party modules often work, but compatibility isn't guaranteed.

Frequently asked questions

How much RAM can the HP ProBook 450 G10 take?

Up to 32 GB, as two 16 GB DDR4 SO-DIMM modules. HP's documents don't state a per-module limit, so 16 GB per module is our reading of the 2 x 16 GB maximum.

What type and speed of RAM does the ProBook 450 G10 use?

Non-ECC DDR4 SO-DIMM running at up to 3200 MT/s (also written as 3200 MHz). It does not use DDR5, and ECC memory is not supported.

Can I mix different RAM modules?

The system will run mixed speeds at the lower speed. For dual-channel performance, use two matching modules. HP also recommends HP-branded memory, as some third-party modules are non-standard.

Does the ProBook 450 G10 have a second M.2 slot?

A second M.2 NVMe slot is offered as an option, but it may not be present or populated on every unit. Check your exact part number and HP's maintenance guide before buying a second SSD.

Can I add a SATA SSD or a 2.5 inch drive?

No. No SATA connection or 2.5 inch bay is listed for this model. Storage is M.2 NVMe only.

Can I upgrade the CPU in the ProBook 450 G10?

Almost certainly not. HP's documents don't name a CPU socket. The processors are 13th-gen Intel U- and P-series mobile chips, which are normally soldered to the board, so treat the CPU as non-upgradable.
