Lenovo IdeaPad Gaming 3 15ACH6 (AMD) RAM, SSD and CPU Upgrade Guide

Updated Oct. 8, 2026 · Written from this device's verified specifications

This guide covers memory, storage and CPU upgrades for the Lenovo IdeaPad Gaming 3 15ACH6 (AMD), model 82K2. The short answer: you can add DDR4-3200 SO-DIMMs and M.2 SSDs, but the CPU is most likely soldered and not upgradable. Your storage layout depends on your graphics card variant, so check that first.

At a glance

  • RAM: 2 DDR4-3200 SO-DIMM slots, 32 GB total is plausible, though Lenovo's documents disagree.
  • Storage: two M.2 NVMe slots, plus a 2.5" SATA bay on models without the RTX 3060.
  • A 2242 SSD needs a separately bought bracket kit.
  • PCIe 4.0 SSDs gain nothing here, since slots run at PCIe 3.0 speeds.
  • CPU: most likely soldered, so there is no socket to upgrade.

RAM: two DDR4-3200 SO-DIMM slots

The laptop has two SO-DIMM slots that take standard DDR4 memory running at up to 3200 MT/s. Both slots appear to be socketed, with no soldered memory. Lenovo's documents don't mention ECC or registered memory, so stick to ordinary unbuffered non-ECC SO-DIMMs.

Lenovo's documents disagree on the maximum. The product reference page says up to 16 GB, while Lenovo's datasheet lists 8, 16 and 32 GB options. The 16 GB figure looks like the largest size Lenovo offered rather than a hard limit, so 2 x 16 GB (32 GB total) is plausible, but only the datasheet supports it.

Many models ship with a single stick (1 x 8 GB or 1 x 16 GB). Adding a matching second module enables dual-channel mode, which helps performance.

Buying tips

  • Buy DDR4-3200 SO-DIMMs, not desktop DIMMs and not DDR5.
  • For dual-channel, match the capacity and speed of the stick already installed, or buy a matched kit and replace both.
  • For 32 GB total, two 16 GB modules are the plausible route, but Lenovo's reference page does not confirm it.

Storage: M.2 NVMe SSDs and, on some models, a 2.5" drive

What you can fit depends on your graphics card. RTX 3060 models have two M.2 2280 slots, both PCIe 3.0 x4, and no 2.5" bay. Models with other graphics (RTX 3050, RTX 3050 Ti, GTX 1650) have one M.2 2242 slot (x4), one M.2 2280 slot (x2) and a 2.5" SATA bay.

On non-3060 models the 2.5" bay and the M.2 2280 slot share resources. You can run two M.2 SSDs, or one 2.5" drive plus one M.2 SSD, but not all three at once. A 2242 SSD needs a 2242 bracket kit, which is bought separately. Lenovo doesn't document a thickness limit for the 2.5" drive.

Lenovo lists tested sizes of up to 512 GB for 2242, up to 1 TB for 2280, and up to 1 TB (product reference page) or 2 TB (datasheet) for the 2.5" drive. These are tested or offered sizes and not necessarily hard limits. Lenovo's footnotes also say 2242 and 2280 SSDs can run at PCIe 3.0 x2 due to an adapter limitation, without saying which models. Expect reduced speeds on the non-3060 layout, and don't pay extra for a PCIe 4.0 drive.

Buying tips

  • Confirm your GPU variant before buying any drive.
  • Choose an NVMe M.2 SSD. A PCIe 3.0 drive is all you need.
  • If you want a 2242 drive, add the 2242 bracket kit to your order.
  • On non-3060 models, remember a 2.5" drive and the 2280 slot can't both be used alongside the 2242 slot.

How to upgrade

Before you start

  • Check your exact model (82K2) and graphics variant (RTX 3060 or another) on the label or in Windows system information.
  • Check what memory is installed now: one stick or two, and its capacity.
  • Have the owner's manual or Lenovo's support page ready for exact disassembly steps.
  • If adding a 2242 SSD, make sure you have the separate bracket kit.
  • Use a small screwdriver and an anti-static strap or a grounded metal surface.

Steps

  1. Back up your data
    Copy important files to an external drive or cloud storage before opening the laptop, especially if you will replace a drive.
  2. Power off and unplug
    Shut the laptop down fully (not sleep), unplug the charger and any accessories, and let it sit for a few minutes.
  3. Ground yourself
    Touch bare metal or wear an anti-static strap before handling components, and hold memory and SSDs by the edges.
  4. Open the case
    Follow the owner's manual for exact disassembly of the bottom cover on this model. Take care with any cables you find inside.
  5. Install the new part
    For RAM, seat the SO-DIMM firmly in its slot at an angle and press it down until it is held in place. For an M.2 SSD, insert it into the correct slot and secure it. A 2242 drive needs its bracket kit. For a 2.5" drive, use the bay on non-RTX 3060 models only.
  6. Close the case
    Refit the cover and screws, then reconnect the charger.
  7. Check that the system sees the part
    Power on and open the BIOS setup or system information to confirm the memory total or new drive is listed. A new blank SSD will also need to be initialised or have an operating system installed before it appears in Windows.

Good to know

  • Lenovo's documents disagree on maximum memory: 16 GB on the reference page, 32 GB (2 x 16 GB) in the datasheet.
  • Lenovo's documents disagree on the largest 2.5" drive: 1 TB or 2 TB. The listed drive sizes are tested sizes, not confirmed limits.
  • The CPU is most likely soldered, but Lenovo's documents don't confirm it.
  • Lenovo's PCIe speed footnotes don't say which models they apply to, so check your own variant.
  • Specifications vary by region and revision, so confirm your exact model and graphics variant before buying.

Frequently asked questions

How much RAM can the IdeaPad Gaming 3 15ACH6 take?

It has two DDR4-3200 SO-DIMM slots. Lenovo's product reference page says up to 16 GB, but Lenovo's datasheet lists 32 GB, so 2 x 16 GB is plausible but not confirmed by the reference page.

Does the IdeaPad Gaming 3 15ACH6 support dual-channel memory?

Yes. Many models ship with only one stick, and adding a matching second module enables dual-channel mode.

Can I add a second SSD to the IdeaPad Gaming 3 15ACH6?

Yes. All variants have two M.2 slots. RTX 3060 models have two 2280 slots, and other models have one 2242 and one 2280 slot. A 2242 SSD needs a separately bought bracket kit.

Does the IdeaPad Gaming 3 15ACH6 support PCIe 4.0 SSDs?

A PCIe 4.0 SSD may work, but it gains nothing. Lenovo's slots are PCIe 3.0, and its footnotes say some drives run at PCIe 3.0 x2.

Can I use a 2.5" hard drive in the IdeaPad Gaming 3 15ACH6?

Only on models without the RTX 3060. That bay shares resources with the M.2 2280 slot, so you can't fill all three drive positions. Lenovo doesn't document a thickness limit.

Can I upgrade the CPU in the IdeaPad Gaming 3 15ACH6?

Probably not. Lenovo's documents don't name a socket, and Ryzen 5000 H-series chips are normally soldered. We can't confirm this, but assume the CPU can't be changed.
