The laptop starts to stutter, programs take forever to open, and in the task manager RAM is 90%+ loaded even at minimum load? These are classic symptoms of low RAM. The problem is relevant both for older devices with 4 GB RAM, and for modern laptops, where resource-intensive applications like Photoshop, Chrome with a dozen tabs or AutoCAD eat up your memory faster than you can blink.

In this article - 12 proven methods Get your laptop back up and running, from basic (which takes 5 minutes) to advanced (which requires technical skills). We'll figure out how determine the real reason for the lack of RAM (spoiler: the culprit doesn’t always “eat” Windows 11), which system settings can be safely optimized, and when it’s time to think about an upgrade. No fuss - only specific instructions with screenshots (in text format) and warnings about common errors.

1. Diagnostics: why the laptop “chokes” without memory

Before cleaning startup or buying a new stick of RAM, you need to understand what exactly eats up memory. Open Task Manager (Ctrl+Shift+Esc) and go to the tab Performance → Memory. Pay attention to three key parameters:

  • 📊 Uploaded: if the value is constantly above 80%, there is objectively not enough memory.
  • 📉 Available: less than 1 GB when idle - critical signal.
  • 🔄 Speed of use: Sudden jumps when opening a browser or game indicate leaks.

Now check the processes tab Details. Sort by Column Memory and look for anomalies:

  • 🦠 Svchost.exe, Runtime Broker or Antimalware Service Executable “eat” >500 MB? Virus or update failure.
  • 🖥️ Chrome/Edge with 5 tabs takes up 2+ GB? Typical for engine-based browsers Chromium.
  • 🎮 Game or Adobe Premiere “rests against” the RAM limit? You'll have to optimize the software or add memory.
📊 What operating system do you have?
  • Windows 10
  • Windows 11
  • Linux
  • macOS
  • Other

Critical moment: if in the task manager you see that the memory is 100% loaded, but the laptop does not slow down, this is ok for Windows. The system uses free RAM to cache frequently used data. Problems start when Available falls below 10% of the total volume.

2. Quick solutions: free up memory in 5 minutes

These methods do not require a reboot and work “here and now”. Start with them if you urgently need to launch a resource-intensive program.

2.1. Closing background processes

Click Ctrl+Shift+Esc, sort processes by memory and terminate unnecessary ones:

  • 🚫 Unnecessary browser tabs (especially with videos or heavy sites like Facebook).
  • 🎵 Music players (For example, Spotify in the background it “eats” up to 300 MB).
  • 📱 Mobile assistants (Your Phone, Link to Windows - up to 500 MB for synchronization).

Important: Don't terminate named processes lsass.exe, winlogon.exe or csrss.exe These are system services. Stopping them will lead to BSOD (blue screen of death).

2.2. Clear cache and temporary files

Type in Windows search Disk Cleanup, select the system drive (C:) and note:

  • 🗑️ Temporary Internet files.
  • 📁 Cart.
  • 🔄 Windows temporary files.

For deep cleaning use the command in CMD (on behalf of administrator):

cleanmgr /sagerun:1
💡

If after cleaning the memory still leaks, check the folder C:\Windows\Temp. Remove files older than 7 days from there - they often remain after installing programs.

2.3. Disabling visual effects

Windows 10/11 spends up to 500 MB RAM on window animation, transparency and shadows. To disable:

  1. Click Win + R, enter sysdm.cpl.
  2. Go to the tab Advanced → Performance → Options.
  3. Select Provide better performance and apply.

Savings: up to 1 GB RAM on weak laptops (for example, Lenovo IdeaPad 3 with 4 GB RAM).

3. Windows optimization: deep settings

If quick methods don't work, it's time to dig deeper. These settings require a reboot, but have a long-term effect.

3.1. Setting up the swap file

Swap file (pagefile.sys) is the “backup RAM” on the hard drive. By default, Windows manages it automatically, but this is not always optimal. Recommendations:

RAM capacity Minimum paging file size Maximum size Recommendation
4 GB 4096 MB 8192 MB Set it to a fixed size (for example, 6144 MB).
8 GB 2048 MB 4096 MB You can reduce it to 3072 MB if you do not use heavy programs.
16 GB+ 1024 MB 2048 MB Disable the page file if you have SSD and enough RAM.

How to change:

  1. Open Control Panel → System → Advanced system settings.
  2. In the section Performance click Options → Advanced → Edit.
  3. Uncheck Automatically select volume and set the values manually.
What happens if you disable the page file completely?

On laptops with 4–8 GB of RAM, this will result in “Out of Memory” errors when opening multiple programs. On 16+ GB you can experiment, but some games (for example, GTA V) require a swap file for stable operation.

3.2. Disabling unnecessary services

Some Windows services run in the background and "steal" up to 1 GB RAM. You can safely disable:

  • 🖨️ Print Spooler (if you are not using a printer).
  • 🌐 Superfetch (SysMain in Windows 10/11) - optimizes the launch of programs, but often overloads memory.
  • 📡 DiagTrack And dmwappushservice (Microsoft telemetry services).

How to disable:

  1. Click Win + R, enter services.msc.
  2. Find the service, right-click → Properties → Startup type: Disabled.
⚠️ Attention: Don't disable services with dependencies (e.g. Windows Audio or Plug and Play). This may result in loss of sound or non-functional USB ports.

3.3. Updating drivers (especially video cards)

Outdated drivers NVIDIA, AMD or Intel Graphics may cause memory leaks. For example, in Windows 11 with drivers Intel UHD 620 2020 version is lost until 300–500 MB RAM due to rendering errors.

Update drivers:

  • 🔧 Through Device Manager (right click on the video card → Update driver).
  • 🌍 From the official website of the manufacturer (for example, NVIDIA or AMD).
  • 🤖 Automatically using Driver Booster or Snappy Driver Installer.

4. Program optimization: which settings “eat up” memory

Even on powerful laptops (ASUS ROG Zephyrus or MSI GS66) programs can consume RAM excessively due to incorrect settings. Let's look at the main “culprits”.

4.1. Browsers: how to reduce memory consumption

Google Chrome, Microsoft Edge And Opera on the engine Chromium known for being gluttonous. One tab with YouTube or TikTok may take up to 1 GB RAM. Solutions:

  • 🔄 Turn it on Memory saving in browser settings (chrome://settings/performance).
  • 🧹 Use extensions like The Great Suspender (pauses inactive tabs).
  • 🦊 Go to Firefox with optimized memory consumption (in the settings, enable config:browser.tabs.unloadOnLowMemory).

Extreme way: launch browser with flag --process-per-site. To do this:

  1. Create a shortcut for Chrome.
  2. In the shortcut properties in the field Object add at the end (after the path): --process-per-site.

4.2. Games and heavy programs

Games like Cyberpunk 2077 or Adobe After Effects may require up to 16 GB RAM, but even with 8 GB you can optimize:

  • 🎮 In the game settings, reduce Texture resolution and turn off Tesselation.
  • 📹B Premiere Pro or Photoshop limit RAM usage in Edit → Preferences → Memory (for example, up to 70% of the total volume).
  • 🖥️ Launch games via Steam with parameter -limitfps 60 (will limit FPS and reduce load).

For NVIDIA- add video cards to NVIDIA Control Panel setting Preferred GPU: High-end - this will reduce RAM usage at the expense of video memory.

4.3. Antiviruses and background utilities

Kaspersky, Avast or McAfee can take up to 1–2 GB RAM in the background. Alternatives:

  • 🛡️ Windows Defender (built into the system, consumes ~200 MB).
  • 🔍 Bitdefender in mode Game Mode (disables scanning during games).
  • ⚡ Malwarebytes (scans on demand, does not hang in the background).

Also check utilities like CCleaner, Razer Synapse or Logitech G HUB - they often start automatically and “eat up” 300–500 MB each.

5. Upgrade: when is it time to add RAM

If all software methods have been tried, and the laptop still “chokes” when opened Excel And Chrome At the same time, it's time to think about an upgrade. Here are the criteria when it is necessary:

  • 💻You have 4 GB RAM or less (even Windows 10 requires a minimum of 4 GB for comfortable operation).
  • 🔄 The laptop is used for video editing, 3D modeling or modern games.
  • 🔍 B Task Manager memory is loaded at 90%+ with minimal load.

Before purchasing a new bar, check:

  1. Maximum supported volume: use Crucial System Scanner or CPU-Z (tab SPD).
  2. Memory type: DDR3, DDR4 or DDR5 (you can’t mix!).
  3. Number of slots: If you have 1 8GB stick, add a second 8GB stick for dual-channel mode (up to 15% performance gain).
Laptop Max. RAM Recommended upgrade Approximate price (2026)
Lenovo ThinkPad T480 32 GB Add 16 GB (2x8 GB) DDR4-2400 ~3 500 ₽
HP Pavilion 15 (2018–2020) 16 GB Replace 4 GB with 16 GB (1x16 GB) DDR4-2666 ~4 200 ₽
ASUS Vivobook S14 12 GB Add 8 GB to soldered 4 GB ~2 800 ₽
⚠️ Attention: On some laptops (eg Apple MacBook Air or Dell XPS 13 after 2020) memory soldered into the motherboard. An upgrade is not possible - only purchasing a new device.

6. Alternative solutions: if an upgrade is not an option

Not everyone has the opportunity to buy a new stick of RAM. In this case it will help:

6.1. Using ReadyBoost

If you have USB flash drive or SD card (from 8 GB, better with interface USB 3.0), it can be used as additional RAM. How to set up:

  1. Connect the flash drive to the laptop.
  2. Open Properties disk → tab ReadyBoost.
  3. Select Provide this device for ReadyBoost technology and allocate as much space as possible.

Effect: performance increase up to 10–15% on hard drives (HDD). On SSD the difference is minimal.

6.2. Cloud services

For resource-intensive tasks (for example, video editing), use cloud solutions:

  • 🎬 Adobe Creative Cloud (video editing in the browser).
  • 🖥️ Shadow PC or GeForce NOW (virtual PC with 16+ GB RAM).
  • 📁 Google Drive/OneDrive for storing files (will free up disk space and reduce the load on RAM).

6.3. Lightweight analogues of programs

Replace the power-hungry software with lighter options:

Program RAM consumption Alternative Savings
Photoshop 1.5–3 GB GIMP or Photopea up to 2 GB
Microsoft Office 500 MB–1 GB LibreOffice or OnlyOffice up to 700 MB
AutoCAD 2–4 GB FreeCAD or DraftSight up to 3 GB
💡

Cloud services and lightweight programs will not replace physical RAM, but will allow you to “squeeze” the most out of the current laptop configuration.

7. Common mistakes: what not to do if you don’t have enough RAM

In an attempt to free up memory, users often perform actions that make the problem worse or lead to data loss. Avoid these mistakes:

  • 🚫 Disabling the page file on laptops with 4–8 GB of RAM. This will lead to errors like OUT OF MEMORY when opening multiple programs.
  • 🔨 Removing system files manually (for example, folders WinSxS). This will break Windows updates.
  • 🔄 Laptop keeps rebooting. Temporary solution, but wear and tear SSD will speed up (especially on cheap models like Kingston A400).
  • 🛠️ Using "optimizers" like CCleaner or Advanced SystemCare. They often delete necessary files and create additional burden.

Also not worth it:

  • 🔋 Disable hibernation (powercfg /h off). On laptops, this increases battery consumption.
  • 🔍 Install antiviruses “as advised”. Many of them (for example, 360 Total Security) themselves become the cause of memory shortage.

FAQ: answers to frequently asked questions

❓ Is it possible to add RAM if the laptop only has 1 slot?

Yes, but you will have to replace the current bar with a more capacious one. For example, if you have 1 4 GB stick, buy 1 8 or 16 GB stick. Make sure that the laptop supports this volume (check on the manufacturer's website or through Crucial System Scanner).

❓ Why was there not enough memory after updating Windows 11?

Windows 11 reserves more RAM for system processes (e.g. Windows Security And Widget Board). Disable unnecessary features:

  1. Click Win + I → Personalization → Widgets → turn off.
  2. B Settings → Privacy → Diagnostics install Optional.

Also check if it is enabled Developer Mode - it adds background processes.

❓ How to check how much RAM my laptop supports?

Methods:

  1. Via CPU-Z: tab SPD → look at the number of slots and memory type.
  2. On the manufacturer's website: enter the laptop model + “max RAM”.
  3. Via Crucial System Scanner (link).
Example: Acer Aspire 5 A515-54 supports up to 20 GB (4 GB soldered + 16 GB in slot).

❓ Will replacing HDD with SSD help if there is a lack of RAM?

No, SSD does not add RAM, but:

  • It will speed up the loading of programs (they will be loaded into RAM faster).
  • Will reduce the load on the processor when working with files.
  • Will make a swap file (pagefile.sys) more efficient.
Conclusion: SSD It will improve overall performance, but will not solve the problem of lack of RAM.

❓ Is it possible to use RAM from a laptop in a desktop PC?

Depends on memory type:

  • 🔹 DDR3/DDR4 SO-DIMM (laptop) not suitable for desktop motherboards (need DDR3/DDR4 DIMM).
  • 🔹 Frequency and timings must also match.
Exception: Some mini PCs (eg Intel NUC) use SO-DIMM.
