Lenovo Legion 5 Gen 10 Upgrade Guide: RAM, SSD and CPU

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

This guide covers adding RAM and M.2 SSD storage to the Lenovo Legion 5 Gen 10 (15IRX10 Intel and 15AHP10 AMD). The short answer: memory and SSDs are upgradable, and the CPU almost certainly is not.

At a glance

  • Two DDR5 SO-DIMM slots; Lenovo lists up to 32 GB (2 x 16 GB) at up to 5600 MT/s.
  • Two M.2 NVMe slots; Lenovo lists up to 1 TB per slot, and larger drives are untested.
  • Check which M.2 length fits before buying: the spec says 2280, but Lenovo ships 2242 drives.
  • On the AMD 15AHP10 the second M.2 slot runs at x2 and is slower.
  • The CPU is most likely soldered; Lenovo's documents don't say so explicitly.

RAM: two DDR5 SO-DIMM slots

The Legion 5 Gen 10 has two DDR5 SO-DIMM slots that work in dual-channel. Lenovo lists up to 32 GB in total (2 x 16 GB). That is the configuration Lenovo offers and tests, not a confirmed hardware limit. Larger modules may work, but nobody has confirmed it, so check before buying 2 x 32 GB.

Most configurations run memory at DDR5-5600. The Intel i7-13650HX model runs DDR5-4800, so faster modules would most likely run at that lower speed. Some models ship with a single 16 GB stick, which leaves a free slot and makes the easiest upgrade a second matching module. Lenovo also lists a 24 GB option (2 x 12 GB), so odd-sized modules are in use. No memory is listed as soldered. Lenovo's documents don't say whether ECC or registered memory is supported, so stick to standard unbuffered DDR5 SO-DIMMs.

Buying tips

  • Buy DDR5 SO-DIMM (laptop) modules, not desktop DIMMs.
  • Look for DDR5-5600 modules; on the i7-13650HX they will most likely run at 4800.
  • If you have one 16 GB stick, adding a second 16 GB module of the same speed gets you to the listed 32 GB.
  • Treat 32 GB modules as untested; 2 x 16 GB is the safe choice.

Storage: two M.2 NVMe slots

There are two M.2 NVMe slots. Lenovo's spec describes them as M.2 2280 PCIe 4.0, but the drives it ships are the shorter M.2 2242 format, and the maximum is listed as 2 x 1 TB in 2242. It's unclear whether the shorter length reflects the physical mounting or only what Lenovo ships. Confirm which lengths fit in Lenovo's Hardware Maintenance Manual before buying, since 2280 is the length most upgraders buy.

On the 15IRX10 (Intel) both slots are PCIe 4.0 x4. On the 15AHP10 (AMD) the first slot is x4 and the second is x2, which caps it at roughly half the theoretical bandwidth (about 4 GB/s against 8 GB/s). Lenovo sells the 15AHP10 with only one SSD, leaving the second slot free for you to fill.

Lenovo lists up to 1 TB per slot. Larger drives may work but are not validated. Lenovo's documents list NVMe only and don't say whether SATA M.2 drives are supported. No 2.5 inch or 3.5 inch bays are mentioned for this laptop.

Buying tips

  • Buy an NVMe PCIe 4.0 drive; skip SATA M.2 drives, as support is not confirmed.
  • Check the 2242 versus 2280 length question in the maintenance manual first.
  • If you want the fastest second drive, note the 15AHP10's second slot is slower (x2).
  • A drive over 1 TB per slot is untested by Lenovo.

How to upgrade

Before you start

  • Find your exact model name (15IRX10 or 15AHP10) on the label or in system settings, as the SSD slot speeds differ.
  • Download Lenovo's Hardware Maintenance Manual for your model and follow its disassembly steps.
  • Back up anything important.
  • Have a small screwdriver and an anti-static wrist strap or a grounded metal surface ready.
  • Check your current RAM and SSD setup first so you know which slots are free.

Steps

  1. Back up your data
    Copy important files to an external drive or cloud storage, especially before swapping or cloning an SSD.
  2. Power off and unplug
    Shut the laptop down fully (not sleep), unplug the charger and any accessories, and wait a minute.
  3. Ground yourself
    Touch bare metal or wear an anti-static strap before handling any component, and hold modules by their edges.
  4. Open the case
    Follow the exact disassembly steps in Lenovo's Hardware Maintenance Manual for your model. Disconnect the internal battery if the manual tells you to.
  5. Install the RAM or SSD
    Seat the new SO-DIMM or M.2 drive in the correct slot, check it sits fully and securely, and avoid forcing anything. If you are replacing a part, remove the old one as the manual describes.
  6. Close the case and reconnect
    Refit the cover and screws, then reconnect power.
  7. Check that the system sees the new part
    Boot into the BIOS or Windows and confirm the new memory total or drive is detected. If it isn't, power off and reseat the part.

Good to know

  • Lenovo's 32 GB RAM and 1 TB per slot SSD figures are what it offers and tests, not confirmed hardware limits.
  • Lenovo's spec lists the M.2 slots as 2280, but shipped and maximum drives are 2242. Confirm which length fits before buying.
  • Lenovo's documents don't say whether SATA M.2 drives work, or whether ECC or registered memory is supported.
  • Lenovo's documents don't say whether the CPU is socketed. It is most likely soldered and not upgradable.
  • Lenovo's documents don't mention 2.5 inch or 3.5 inch bays, card readers or other expansion slots for this laptop; check the maintenance manual for your exact model.
  • The 15AHP10's second M.2 slot is x2, so it is slower than the 15IRX10's second slot.
  • Opening the laptop may affect your warranty; check Lenovo's terms before you start.

Frequently asked questions

How much RAM can the Legion 5 Gen 10 take?

Lenovo lists up to 32 GB (2 x 16 GB DDR5 SO-DIMM). That is the tested offering, not a confirmed hardware limit. Larger modules may work but are unconfirmed.

What type and speed of RAM does it use?

DDR5 SO-DIMM. Most configurations run at 5600 MT/s, while the i7-13650HX model runs at 4800 MT/s.

Can I add a second SSD to the Legion 5 Gen 10?

Yes. It has two M.2 NVMe slots, and some models ship with one drive and a free slot. On the 15AHP10 the second slot is x2 and slower than the first.

Does it take a 2280 SSD?

Unclear. Lenovo's spec describes the slots as M.2 2280, but the drives it ships and lists as the maximum are M.2 2242. Check the maintenance manual for your model before buying.

What is the biggest SSD it supports?

Lenovo lists up to 1 TB per slot (2 TB across two slots). Larger drives may work but are untested.

Can I upgrade the CPU?

Almost certainly not. Lenovo's documents don't say whether the processor is socketed, but laptop chips of this kind are normally soldered to the motherboard. Treat the CPU as fixed unless a service manual says otherwise.
