Acer Nitro 5 AN515-54 upgrade guide: RAM, SSD and CPU

Updated Oct. 19, 2026 · Written from this device's verified specifications

The Nitro 5 AN515-54 is one of the friendlier gaming laptops to upgrade: both memory slots are free for you to fill, and there is room for up to three drives. The one thing you cannot change is the processor. Stock configurations vary by SKU and region, so check what your unit shipped with before ordering anything.

Release
First available to buy.		 2019 Estimate iFixit states released in 2019. Corroborated by Acer's user manual (rev. Aug 2019) and a community-reported unit manufactured 2019-03-30, suggesting first availability in spring 2019 (Q2). Acer's own support page has a 'Release Date' field but the value was not retrievable.

End of life (EOL)
The manufacturer stops developing the product: no new BIOS, firmware or driver releases.		 March 2, 2021 Estimate De facto end of firmware/software support: last BIOS published is v1.33 dated 2 March 2021, with no newer BIOS and no model-specific drivers since. Community-verified rather than an Acer lifecycle statement.

End of standard support (EOSL)
Standard warranty and support contracts can no longer be renewed.		 2024 Estimate Derived from Acer Japan policy (support ends 5 years after sales start) applied to a 2019 model. Policy-derived, not a confirmed per-model entry; the authoritative per-model date would be in the 'Acerサポート期間満了品リスト' PDF on this page. Other regions may differ.

Memory (RAM)

There are two 260-pin DDR4 SO-DIMM slots, and nothing is soldered to the board - every gigabyte is removable. That means you can start from scratch or just add a second stick to whatever is already installed.

The limits: 16 GB per slot, 32 GB total. The platform is native DDR4-2400/2666 at 1.2 V. Faster modules such as DDR4-3200 will physically work but clock down to 2666 MT/s (or 2400 MT/s in some configurations), so there is no reason to pay a premium for them. You need standard unbuffered, non-ECC SO-DIMMs - server or ECC memory is not supported.

What to watch out for: for dual-channel performance (a real boost in games), install a matched pair - same size, speed, voltage and timings - so 8+8 GB or 16+16 GB. Mixed modules may still run, but you lose that benefit. Before buying, check your current speed and stick size in Task Manager under Memory.

Buying tips

  • Matched pairs only: 8+8 GB or 16+16 GB for dual channel
  • DDR4 SO-DIMM, 260-pin, 1.2 V, non-ECC unbuffered
  • DDR4-2666 is the sweet spot; 3200 MT/s sticks just run slower
  • Check Task Manager to see what is installed now

Storage (SSD / HDD)

This model has three drive positions: two M.2 slots and one 2.5-inch SATA bay. Both M.2 slots accept 2242, 2260 and 2280-length modules, but they are not identical - one is PCIe-only and the other is a PCIe/SATA combo slot. Before buying a SATA M.2 drive, open the case and check which slot is already populated, because the PCIe-only slot will not accept a SATA drive.

Speed-wise, the M.2 links are PCIe 3.0, but sources disagree on the lane width: the board schematic shows PCIe 3.0 x4, while Acer's community support describes both slots as PCIe 3.0 x2 with a ceiling around 2000 MB/s. Either way, a PCIe 3.0 (Gen3) NVMe drive is the sensible buy - a Gen4 drive brings no benefit here and adds cost and heat. RAID 0 across the two M.2 slots is supported, but it gives you no redundancy, so only use it alongside a good backup routine.

The 2.5-inch bay takes SATA SSDs and hard drives up to 7 mm thick; 9.5 mm drives will not fit. Two practical caveats: there is no hard drive door, so the whole bottom panel has to come off, and some units ship without the SATA cable and mounting bracket. Check inside your machine before ordering a 2.5-inch drive. Shorter M.2 drives (2242/2260) also need the mounting post moved or added to sit properly.

There is no memory card reader on this laptop, so if you need one it will have to be a USB device.

Buying tips

  • Gen3 (PCIe 3.0) NVMe M.2 drives - Gen4 adds nothing here
  • Identify which M.2 slot is free before buying a SATA M.2 drive
  • 2.5-inch drives: 7 mm max, and check for a cable/bracket first
  • 2242/2260 drives need the right mounting post

How to upgrade

Before you start

  • Back up anything important before opening the case.
  • Shut the laptop down fully and unplug the charger.
  • Ground yourself (touch a metal object or use an anti-static strap) before handling components.
  • Remove the bottom panel to reach the memory and drive bays. There is no separate hard drive door, and Acer's user manual is the reference for exact screw locations and disassembly - follow it for your unit.
  • Fit the memory or drive, then close the case, reconnect power and switch on.
  • Check that the BIOS or your operating system sees the new part at the expected size and speed. If a new drive is missing entirely, reseat it and confirm it is in a slot that supports that drive type.

Steps

  1. RAM
    Back up, power off and unplug, ground yourself, open the bottom panel, insert the SO-DIMM at an angle and press it down until the clips click, close the case and confirm the new total in the BIOS or Task Manager.
  2. Storage
    Back up, power off and unplug, ground yourself, open the bottom panel, screw the M.2 drive into the matching mounting post (or fit the 2.5-inch drive with its cable and bracket if your unit has them), close the case and confirm the drive appears in the BIOS and in your operating system.
  3. CPU
    Not applicable - the processor is soldered to the motherboard.

Good to know

  • Stock configurations vary by SKU and region - verify what your unit shipped with before ordering.
  • Acer's documents and community posts disagree on the M.2 lane width (PCIe 3.0 x4 vs x2); either way, Gen3 drives are the right purchase.
  • Acer has not published maximum per-drive capacities; larger drives are generally expected to work but are not officially confirmed.

Frequently asked questions

How much RAM can the Nitro 5 AN515-54 take?

32 GB in total, as 2x 16 GB DDR4 SO-DIMMs. Nothing is soldered, so both slots are yours to use.

Does it support DDR4-3200 memory?

Physically yes, but the platform runs at DDR4-2400/2666, so such modules clock down to 2666 MT/s (or 2400 MT/s in some configurations). Buy DDR4-2666 and save your money.

Can I upgrade the CPU in the AN515-54?

No. The processor is a soldered BGA1440 Coffee Lake-H chip - there is no socket. The 8th/9th Gen Core H-series CPU your machine shipped with is permanent.

How many SSDs can I install?

Up to three drives: two M.2 modules (2242/2260/2280) plus one 2.5-inch SATA drive up to 7 mm thick.

Do I need a bracket or cable for a 2.5-inch drive?

Possibly. Some units ship without the SATA cable and bracket, and there is no hard drive door - the whole bottom panel comes off. Check inside your machine before buying a 2.5-inch drive.

Does the Nitro 5 AN515-54 have a memory card reader?

No, this model has no card reader.
