Memory (RAM)

The ProBook 450 G7 has two DDR4 SO-DIMM slots, and both are accessible to you - nothing is soldered. HP lists 4 GB, 8 GB and 16 GB modules, for a maximum of 32 GB in a 2 x 16 GB setup. The memory runs in dual-channel mode at DDR4-2666 (PC4-2666), 260-pin SO-DIMM, standard 1.2 V unbuffered non-ECC.

DDR4-3200 modules physically fit and HP even lists some as spare parts, but the Comet Lake-U memory controller runs them at 2666 anyway, so only buy them if they happen to be cheaper. If you mix speeds, everything runs at the slower module's speed. A small number of third-party datasheets claim a 16 GB maximum - that is data carried over from the older ProBook 450 G6. HP's own specifications, service guide and a shipped 2 x 16 GB configuration all confirm 32 GB.

Buying tips

  • Buy a matched 2 x 16 GB DDR4-2666 kit for the full 32 GB in dual-channel.
  • Stick to 1.2 V JEDEC DDR4-2666/3200 SO-DIMMs from major brands such as Crucial, Samsung or SK Hynix.
  • Skip ECC or registered/buffered modules - this machine needs plain unbuffered non-ECC.

Storage (SSD / HDD)

There are two storage bays, and you can use both at once.

M.2 slot: one M.2 2280 slot (22 x 80 mm) that accepts either an M.2 SATA drive or a PCIe NVMe drive - it is the same slot, so you cannot have two M.2 drives. NVMe is PCIe Gen3 x4. HP's own options ranged from a 128 GB M.2 SATA drive to a 512 GB TLC NVMe drive rated up to 2600 MB/s read, while the cheaper 'Value' drives were roughly 1700 MB/s class, so real-world speeds depend on the drive. Only 2280 length fits - 2230, 2242 and 2260 drives do not.

2.5-inch bay: a separate SATA bay takes 7 mm thick 2.5-inch drives only. 9.5 mm and 15 mm drives will not fit. On used units, check that the SATA cable, caddy and bracket are present - machines that shipped with an M.2 drive are often missing them, and you will need them to add a 2.5-inch SSD or HDD.

HP documents no capacity limit for either bay. Optane H10 configurations need a specific driver stack and are not a good upgrade path; if you are buying used, a plain NVMe SSD is the better bet.

Buying tips

  • A 1 TB M.2 2280 NVMe (PCIe Gen3) SSD is the sensible end-of-life upgrade alongside extra RAM.
  • For extra bulk storage, any 7 mm 2.5-inch SATA SSD or HDD fits - verify the cabling is installed first.
  • Don't buy M.2 SATA-only or shorter M.2 drives expecting them to work without checking.

How to upgrade

Before you start

  • Check your exact configuration by serial number on HP's support site - memory, storage cabling and options like WWAN vary by region and SKU.
  • Some regional variants are WWAN-capable; if you need cellular, verify the antennas and slot on your own unit.
  • Note that the platform's WLAN module is supported under Windows 11 according to HP.

Steps

  1. Back up your data
    Before touching anything, back up anything you care about - especially if you plan to clone or replace the current drive.
  2. Shut down and disconnect power
    Fully shut the laptop down, unplug the AC adapter and remove anything connected to the ports.
  3. Ground yourself
    Work on a clean, non-static surface and discharge any static on yourself first - memory modules and SSDs are sensitive to it.
  4. Open the case
    Open the bottom of the laptop using the procedure in HP's Maintenance and Service Guide - it shows the exact screw locations and any latches for this model.
  5. Install the part
    Seat the SO-DIMM or M.2/2.5-inch drive as shown in the guide. For a 2.5-inch drive, make sure the SATA cable, caddy and bracket are fitted - on units that shipped M.2-only they may be missing.
  6. Close up and power on
    Reassemble, reconnect the AC adapter and start the laptop.
  7. Check the BIOS/firmware sees it
    Enter the BIOS on startup and confirm the new memory size and drive are detected. If a storage drive is missing, reseat it and check the cabling before assuming the part is faulty.

Good to know

  • Regional configurations vary - verify your own unit's memory, storage cabling, display and WWAN status before buying parts.
  • One widely circulated datasheet for this model carries over ProBook 450 G6 figures (16 GB DDR4-2400 maximum, MX130 graphics). For the G7, trust 32 GB DDR4-2666 and MX250 where discrete graphics are fitted.

Frequently asked questions

How much RAM can the HP ProBook 450 G7 take?

32 GB total, as 2 x 16 GB DDR4-2666 SO-DIMMs. Both slots are accessible and nothing is soldered. A few third-party sheets say 16 GB - that figure belongs to the older ProBook 450 G6.

Does the ProBook 450 G7 support 32 GB of RAM?

Yes. HP's specifications and the service guide both state up to 32 GB (2 x 16 GB) DDR4-2666, and real configurations with 32 GB exist.

Can I upgrade the CPU or GPU?

No. The processor is soldered (BGA 1528) and the discrete GPU, where fitted, is soldered as well. Only 10th Gen Comet Lake-U chips were offered: i3-10110U, i5-10210U and i7-10510U.

Does it support NVMe SSDs?

Yes. The M.2 2280 slot takes either an M.2 SATA drive or a PCIe NVMe drive (Gen3 x4). It is one shared slot, so you can't fit two M.2 drives - but you can add a 2.5-inch SATA drive in the second bay at the same time.

Can I use DDR4-3200 memory?

Physically yes, but it will run at 2666 MT/s, since that is the speed the Comet Lake-U memory controller supports. Only choose 3200 modules if they cost less than 2666 ones.

What size drives fit in the 2.5-inch bay?

7 mm thick 2.5-inch SATA drives only. 9.5 mm and 15 mm drives don't fit. On used units, first confirm the SATA cable, caddy and bracket are present.
