This model has two RAM slots, if I understand things correctly. I've found somewhat conflicting information on the internet about whether I can change the non-soldered 4 GB RAM module to a 32 GB one or just a 16 GB one. Also, what specifics should I make sure to check when choosing a RAM module to buy?

It's really hard to find serious technical information on Acer laptops… Only the user manual is available online. I'm aware that service manuals are not public, but if someone were willing to send it to me under the table, I would be much obliged. This is the way under the table: [Content Removed]

    Hi @benjaminaaron _m — here's the scoop on upgrading the RAM in your A515-51G-58G3, based on hands-on checks and practical experience:

    🔧 Most units in this series have:

    • 4GB soldered to the motherboard (not removable)
    • One SO-DIMM slot for expansion

    📌 That means your max RAM is 20GB (4GB onboard + 16GB in the slot). Ignore suggestions about installing a 32GB stick—they don’t apply if there’s only one slot, and I’ve yet to see a legit A515-51G with dual-slot, no-soldered RAM.

    Want to verify what’s soldered and what’s not?

    You can:

    1. Physically open the laptop (you'll need to anyway to upgrade). Look for:
      • A single SO-DIMM slot
      • No second slot = no 32GB dreams
    2. To find the specs. of the soldered RAM, run as Administrator this command: wmic memorychip list full
    3. Match your new RAM to the soldered specs: WMIC often gives a part number (e.g. M471A5244CB0-CRC) — plug that into Google or the vendor’s site to get:
      • Speed (e.g. DDR4-2400)
      • Timings (e.g. CL17)
      • Rank and voltage This helps avoid mixing modules that’ll default to the slower one or cause dual-channel issues.

    💡 Bonus tip: If WMIC shows two memory modules, you probably don’t have soldered RAM—just two removable slots (rare for this model, but worth confirming physically).
