Your computer feels like it’s drowning. You click a tab in Chrome, and nothing happens for three seconds. The mouse stutters. You hear the fans kick into high gear, screaming for mercy. Most people think the solution is just buying more hardware, but honestly, that’s like buying a bigger trash can because you don’t want to take the garbage out. It’s a temporary fix for a much deeper mess. If you want to know how to reduce RAM usage, you have to stop thinking about memory as a bottomless pit and start treating it like the finite, precious resource it actually is.
Windows and macOS are both greedy. They’ll take whatever you give them. If you have 8GB, they’ll want 7GB. If you have 32GB, they’ll somehow find a way to eat 20GB just sitting at the desktop. It’s frustrating.

The Chrome Problem (And Why Everyone Blames It)
Let's talk about the elephant in the room. Google Chrome is a notorious memory hog. It’s basically the "Pac-Man" of modern software. Every single tab you open is a separate process. Why? For stability. If one tab crashes, the whole browser doesn't die. That’s great for your sanity, but it’s brutal for your Random Access Memory.
To really get anywhere with how to reduce RAM usage, you’ve got to tackle the browser first. Open your Task Manager (Ctrl + Shift + Esc on Windows) or Activity Monitor (Cmd + Space, type it in on Mac). Look at the "Memory" column. You’ll likely see a dozen "Google Chrome" entries. It looks like a glitch, but it’s not.
One real-world trick that actually works is using a "tab suspender" extension. Tools like Memory Saver (which is now built directly into Chrome settings) or third-party options like The Great Suspender (though watch out for the forks that went sketchy a few years back) essentially "hibernate" tabs you aren't looking at. They’re still there, but they aren’t eating your RAM. You click them, they reload, and you save gigabytes. Literally gigabytes.
I’ve seen people go from 90% memory pressure down to 40% just by enabling Chrome’s built-in "Memory Saver" mode. Go to Settings > Performance. Flip the switch. It’s that simple.
Kill the Background Ghosts
Some apps are just plain rude. You think you closed them? Nope. They’re sitting in your system tray or running a "helper" service in the background. Discord, Steam, Spotify, and Teams are some of the worst offenders.
Teams is especially egregious. It’s built on Electron—a framework that basically wraps a website into an app. This means running Teams is like running another instance of Chrome. If you have it set to "Auto-start," you’re losing 500MB of RAM the second you log in, before you’ve even sent a single "Good morning" message.

Go to your startup settings. On Windows 11, it’s under Settings > Apps > Startup. On Mac, it’s under System Settings > General > Login Items. Be ruthless. If you don't need it the second your computer turns on, toggle it off. You can always open it manually when you actually need to use it.
Does Restarting Actually Help?
Yes.
Seriously.
Software leaks memory. It’s a fact of life. A developer forgets to write a line of code that tells the computer "Hey, I’m done with this 200MB of data, you can have it back." Over days or weeks, these "leaks" add up. Windows "Fast Startup" is also a bit of a lie. When you click "Shut Down," Windows actually saves the state of the kernel to the disk to make booting faster next time. This keeps those leaks alive.
To truly clear things out, you need to click "Restart," not "Shut Down." This forces the system to actually dump the RAM and start from a clean slate. It’s the oldest advice in the book because it’s the only one that works 100% of the time.
Visual Effects Are Costing You More Than You Think
We all like the pretty transparency effects and the smooth animations when a window minimizes. But those are powered by the GPU and the RAM. If you’re on a machine with integrated graphics—which most laptops are—your system RAM is shared with your video card.
If you want to know how to reduce RAM usage on an older machine, you have to sacrifice the eye candy.
- Hit the Windows Key and type "Adjust the appearance and performance of Windows."
- Select "Adjust for best performance."
- It’ll make your OS look like Windows 95 for a second, but suddenly, the lag is gone.
If that’s too extreme, just uncheck "Animate windows when minimizing and maximizing" and "Show shadows under windows." You won’t miss them after five minutes, but your RAM will thank you.
The Myth of "RAM Cleaners"
Stop downloading "RAM Boosters" or "Memory Cleaners." Just stop.

Most of these programs are "snake oil." They work by forcing other programs to dump their memory into the "page file" on your hard drive. This makes the "Used RAM" number go down in your task manager, which makes you feel good, but it actually makes your computer slower. Why? Because now, when you go back to that app, your computer has to fetch that data from the slow hard drive instead of the fast RAM.
MacOS and Windows 10/11 have incredibly sophisticated memory management. They want your RAM to be mostly full. Empty RAM is wasted RAM. The problem is "Memory Pressure," not just the percentage used. You want your OS to manage it, not some third-party app that’s probably just tracking your data anyway.
Advanced Tactics: The Page File and Virtual Memory
When you run out of physical RAM, your computer uses a "Page File" or "Swap." It carves out a chunk of your SSD or Hard Drive and pretends it’s RAM.
If you’re still using a mechanical Hard Disk Drive (HDD), this is why your computer freezes. HDDs are thousands of times slower than RAM. If your system is "swapping" to an HDD, you’re in for a bad time. Upgrading to an SSD is the single best thing you can do for a computer that feels like it’s struggling with memory.
For people on Windows, you can manually check your Virtual Memory settings. Go to System > About > Advanced System Settings > Performance > Advanced > Virtual Memory. Usually, you should let Windows manage this. But if you’ve manually set it to a small size years ago and forgot, that might be why your apps are crashing. Set it to "Automatically manage paging file size for all drives."
Hardware: When Software Fixes Aren't Enough
Sometimes, you just don't have enough. If you are trying to run modern Windows or macOS on 4GB of RAM in 2026, you’re fighting a losing battle. Even 8GB is starting to feel tight for anyone who does more than just check email.
If you have a desktop, adding RAM is cheap and easy. It’s like plugging in a Lego brick. If you have a laptop, check if it’s "soldered." Many modern laptops (especially MacBooks and thin ultrabooks) don't let you upgrade. You’re stuck with what you bought.
Before you go out and buy a new machine, look at the "Compressed" memory in your Task Manager. Windows actually compresses data in the RAM to fit more in. If you see a high "Compressed" number, it means your CPU is working extra hard to make up for your lack of RAM. This is a clear sign you actually need a hardware upgrade.
Actionable Steps to Take Right Now
- Audit your browser. Use a tab suspender or simply close the fifty tabs you haven't looked at since last Tuesday. Use the built-in "Task Manager" in Chrome (Shift + Esc while in the browser) to see which specific tab is the culprit. Usually, it's a news site with fifty auto-playing ads.
- Clean up your startup. Open Task Manager, go to the Startup tab, and disable everything that isn't essential. If you don't know what it is, Google it before disabling.
- Check for "Zombies." Sometimes an app crashes but the process stays alive. If you see "High" power usage or memory usage for an app you aren't even using, "End Task" immediately.
- Update your drivers. Specifically your graphics drivers. Memory leaks in GPU drivers are incredibly common and can eat up system RAM.
- Scan for Malware. Some miners or "adware" run in the background specifically to use your resources. Run a scan with Malwarebytes just to be sure your RAM isn't being used to mine someone else's cryptocurrency.
- Physical Restart. Don't just close the lid of your laptop. Do a full "Restart" once every couple of days to clear the "cache" and reset the kernel.
Reducing memory usage isn't a one-time thing you do and forget. It’s about being mindful of what you leave running. Treat your RAM like desk space; if you keep piling papers on it, eventually you won't have room to write. Keep it clean, keep it lean, and your computer will actually feel like the fast machine you paid for.
