You decide to increase the volume RAM (RAM) in your laptop, but don't know where it is? This task seems simple only at first glance. Depending on the device model, slots RAM may be hidden under a separate cover, integrated into the motherboard, or absent altogether. In this article, we will analyze all possible options for the location of RAM, learn how to determine the type of memory and give practical advice on replacing it - without the risk of damaging the laptop.

It is important to understand that modern ultrabooks (for example, Apple MacBook Air or Dell XPS 13) are often used soldered memory, which cannot be replaced manually. But gaming or office models (Lenovo Legion, HP Pavilion, ASUS TUF) are usually equipped with removable modules. How can you find out what exactly is installed on your device? Let's start with the basics.

How to determine the type of RAM in a laptop before disassembling

Before arming yourself with a screwdriver, check the software specifications of your laptop. This will save time and eliminate unnecessary disassembly. Here are 3 reliable ways:

  • 🔍 Via Windows Task Manager: press Ctrl + Shift + Esc, go to the Performance tab → Memory. The type is specified here (for example, DDR4), volume and number of used slots.
  • 📋 Using CPU-Z: download the utility from the official website, open the tab SPD. Select a slot from the drop-down menu - the program will show the manufacturer, model of the module and its parameters.
  • 🌐 By laptop model on the manufacturer's website: Enter the device serial number (usually on the sticker at the bottom) on the brand's support page. There are often disassembly diagrams there as well.

Pay attention to the parameter Form Factor in CPU-Z. If it is indicated there SODIMM, memory is removable. If Onboard or Soldiered — it is soldered into the motherboard. In the latter case, replacement is possible only at a service center (and even then not always).

Where is the RAM physically located in a laptop: 4 possible options

The design of laptops varies greatly, but all RAM layout options can be divided into four categories. Let's look at each with examples of models.

  1. Separate cover for RAM - the most convenient case. Usually it is located on the bottom panel and is marked with a memory icon (three waves) or the inscription RAM/Memory. Example: Lenovo ThinkPad T-series, Dell Latitude.
  2. Under the common bottom cover - Requires complete disassembly. The RAM slots are located next to the cooler or battery. Example: HP Omen, ASUS ROG Strix.
  3. Under the keyboard - typical for older models (Sony VAIO before 2015) or some ultrabooks. There is a high risk of damaging the cables here!
  4. Soldered into the motherboard - typical for thin laptops (Apple MacBook Pro since 2016, Microsoft Surface). Replacement is impossible without soldering.

Critical detail: 60% of laptops from 2020–2026 have one RAM slot soldered in and the other removable (hybrid design). For example, in Lenovo IdeaPad 5 8 GB are soldered, but there is a free slot for an upgrade. Check this in advance so as not to buy an extra module.

RAM location type Examples of models Difficulty of access Are special tools needed?
Separate cover Dell XPS 15, Lenovo ThinkPad P1 Low Phillips #0 screwdriver
Under a common cover ASUS ZenBook Pro, HP Spectre Average Plastic pick, screwdriver
Under the keyboard Acer Aspire VN7, MSI GS65 High Mediator, tweezers, thermal paste (when removing the cooler)
Soldered into the board Apple MacBook Air M1, Huawei MateBook X Pro Replacement not possible —

Step-by-step instructions: how to get to RAM

If you are convinced that the RAM is removable, we proceed to disassembly. Important: Before starting work, disconnect the laptop from the network, remove the battery (if it is removable) and put on an antistatic wrist strap (or touch the metal case of the system unit to remove static).

Turn off power and remove battery

Prepare the workplace (soft surface, good lighting)

Take photographs of the location of screws and modules

Use a plastic pick to open the lid

Check the compatibility of the new memory with the motherboard -->

Next we follow the algorithm:

  1. Remove the bottom cover:
    • Remove all screws (they may be hidden under the rubber feet).
    • Gently pry the lid open with a plastic pick, starting from the corner. On some models (HP Pavilion) latches are fragile - do not use excessive force!
  2. Find the RAM slots:
    • They are usually located next to the cooler or under metal protection.
    • If you see two slots, but one is empty, your laptop supports the upgrade. If both are busy, you will have to replace both modules (for dual-channel mode).
  3. Retrieve old memory:
    • Press the latches on the sides of the module and it will rise at an angle of 30°.
    • Carefully pull out the bar without touching the contacts.
  4. Install a new one:
    • Insert the module into the slot at the same angle until the latches click into place.
    • Make sure that the memory sits straight - distortions lead to unstable operation.

1) Is the memory installed correctly (try rearranging the modules).

2) Compatibility of the new RAM with the processor (for example, Intel Core i7-12700H supports DDR5-4800, but not DDR4).

3) Slot contacts - if necessary, clean them with an eraser.-->

What to do if there are no RAM slots: alternative solutions

Found that the memory is soldered in? Don't despair - there are several ways to optimize performance:

  • 🔄 Use a swap file: reconfigure it to Control Panel → System → Advanced system settings → Performance → Settings → Advanced. The recommended size is 1.5x the amount of RAM.
  • 🖥️ Cloud solutions: services like Shadow PC or GeForce NOW allow you to “rent” the power of a remote PC with 16+ GB of RAM.
  • 🛠️ Replacing the motherboard: a radical method for enthusiasts. For example, in MacBook Pro 2015 you can install a board from the 2017 model with support DDR4.
⚠️ Attention: Programs like RAM Disk or "memory optimizers" (for example, CleanMem) often do more harm than good. They artificially clear the cache, which leads to frequent access to the hard drive and accelerated wear and tear. SSD.

If your task is to run modern games or work in Photoshop, consider purchasing an external GPU through Thunderbolt 3. Devices like Razer Core X allow you to connect a video card with its own memory, relieving the laptop’s RAM.

Common mistakes when replacing RAM and how to avoid them

Even experienced users sometimes make mistakes that lead to unstable system operation. Here are the most common of them:

  • 🔌 Module incompatibility: mixing DDR3 And DDR4 or strips with different frequencies (for example, 2400 MHz And 3200 MHz). This results in slow performance or boot failure.
  • 🔧 Incorrect installation: The module is not inserted fully or at an angle. Check the latches - they should click.
  • ⚡ Static electricity: Even a weak discharge can damage the contacts. Always use an antistatic wrist strap or touch the metal casing of your PC before operating.
  • 🔄 Dual channel violation: if you have two slots, install the same slots (for example, 2x8 GB Corsair Vengeance). Otherwise, the performance gain of up to 15% will be lost.
⚠️ Attention: If, after replacing the RAM, the laptop turns on, but the screen remains black and the cooler is running at maximum speed, you most likely installed incompatible memory. Try booting with one slot (checking each slot in turn).

Another trap - BIOS. In some laptops (MSI Modern 14, some Lenovo Yoga) after upgrading the RAM, you need to reset the BIOS settings (remove the battery for 30 seconds or use a jumper CLR_CMOS). Otherwise, the system may not see the new memory.

How to choose RAM for a laptop: 5 key parameters

When purchasing new RAM, pay attention not only to the capacity, but also to the technical characteristics. Here's what really matters:

  1. Memory type:
    • DDR4 - the most common (up to 3200 MHz).
    • DDR5 - for new processors (Intel 12th–14th generation, AMD Ryzen 6000/7000).
    • LPDDR4X/LPDDR5 — low-voltage memory for ultrabooks (cannot be replaced).
  • Form factor: for laptops only SODIMM (unlike DIMM for PC).
  • Frequency: Must be supported by the processor. For example, Intel Core i5-1135G7 officially working with DDR4-3200, but can “raise” and 3600 MHz (with acceleration).
  • Timings: the lower (for example, CL16 instead of CL19), the better. But for office tasks this is not critical.
  • Manufacturer: reliable brands - Corsair, Kingston, Crucial, Samsung. Avoid no-name memory - it often gives errors.

    • For gaming laptops (ASUS ROG Zephyrus, Lenovo Legion) it is optimal to take two modules of the same size (for example, 2x16 GB) to activate the dual-channel mode. For office tasks (HP EliteBook, Dell Inspiron) one 16 GB module is enough.

    What is Rank in RAM characteristics?

    Rank is a logical block of memory on a module. There are Single Rank (1R) and Dual Rank (2R). The latter provide a performance increase of up to 5–10% in multi-threaded tasks (rendering, code compilation), but are more expensive. There is no difference for games.

    Specifics of different brands: where to look for RAM in laptops Lenovo, HP, ASUS and others

    Each manufacturer uses unique design solutions. Here is a short guide to popular brands:

    Brand Typical RAM layout Disassembly Features Models with soldered memory
    Lenovo Separate cover (ThinkPad) or under a common cover (IdeaPad, Legion) Screws under rubber feet. B Legion 5 you need to remove the cooler to access the second slot. Yoga Slim 7, ThinkBook 13x
    HP Under the general cover, next to the battery Fragile latches! B Omen 15 RAM under a metal screen. Spectre x360, Envy 13
    ASUS Separate cover (ROG) or under the keyboard (ZenBook) B ROG Strix slots under the radiator - you will have to disconnect the tubes. ZenBook Flip, VivoBook S14
    Dell Separate cover (XPS, Latitude) or under a common cover (Inspiron) B XPS 13 The memory is often soldered, even if there is a slot. XPS 13 (2020+), Alienware m15 R4
    Apple Soldered into the board (all models from 2016) B MacBook Pro 2015 and older RAM is removable, but a special P5 screwdriver is required. All M1/M2 models

    For laptops Acer And MSI The location of the RAM under a common cover is typical, but in game series (Acer Predator, MSI GE76) there are often two removable slots. In budget models (Acer Aspire 3) there can be only one slot, and the second is soldered.

    💡

    Before purchasing new memory, always check the maximum supported capacity for your model on the manufacturer's website. For example, Lenovo ThinkPad T14 Officially supports up to 48 GB, but some users have successfully installed 64 GB (without guarantee of stability).

    FAQ: Frequently asked questions about replacing RAM in a laptop

    Is it possible to replace RAM in a laptop if it is soldered in?

    Technically yes, but it requires professional soldering equipment (BGA station) and experience. In 99% of cases, it’s easier to sell your old laptop and buy a new one with the required amount of memory. The exception is collectible models (for example, MacBook Pro 2012), where the upgrade is justified.

    How can I find out how many RAM slots my laptop has?

    Methods:

    1. Run CPU-Z, go to the tab Mainboard → look at the field Chipset. Enter the chipset model into Google with the query “memory slots”.
    2. Use the utility HWiNFO: in section Memory the number of channels and slots will be indicated.
    3. Disassemble the laptop and look physically (relevant if there is no documentation).

    What happens if you install RAM with a frequency higher than the processor supports?

    The laptop will work, but the memory will operate at the maximum supported frequency. For example, if you set DDR4-3600 in Intel Core i5-8250U (maximum 2400 MHz), the module will automatically reduce the frequency. In this case, it makes no sense to overpay for high-frequency memory.

    Do I need to update the BIOS after replacing RAM?

    Only if the new memory is not detected or the laptop does not turn on. For example, in some Lenovo Legion BIOS update required to support modules DDR4-3200. Check section Support on the manufacturer's website - there should be compatibility notes there.

    Can I use RAM from a desktop PC in a laptop?

    No. Laptops use form factor SODIMM (short bars), and desktop PCs - DIMM (long). They are not physically compatible. The voltage also differs: SODIMM usually works at 1.2V or 1.35V, and DIMM — 1.5V.
