How To Allocate More Ram To Steam Games

Allocating more RAM to Steam games can improve performance in memory-intensive titles. If you’ve ever wondered how to allocate more ram to steam games, you’re not alone. Many gamers hit lag spikes or stuttering when their system runs out of memory. This guide will show you practical steps to give your games the RAM they need, without buying new hardware.

First, let’s clear up a common myth. You can’t just “assign” more RAM to a game like you would with a file. Instead, you optimize your system so the game gets priority access to available memory. Think of it as clearing the table so your game has room to spread out.

We’ll cover everything from Windows settings to Steam launch options. By the end, you’ll know exactly how to free up RAM and make your games run smoother. No technical degree required.

Why Your Steam Games Need More Ram

Modern games are memory hogs. Titles like Cyberpunk 2077 or Call of Duty can eat 8GB or more just by themselves. When your system runs out of physical RAM, it starts using your hard drive as “virtual memory.” That’s much slower and causes stuttering.

You might see low FPS, long loading times, or random crashes. Allocating more RAM to the game process helps prevent these issues. But the trick is to reduce competition from other programs.

Your computer has a fixed amount of RAM. If you have 16GB total, and Windows uses 4GB, background apps use 3GB, and a browser uses 2GB, only 7GB is left for your game. That’s often not enough for modern titles.

How To Check Your Current Ram Usage

Before you start tweaking, see what’s happening now. Press Ctrl + Shift + Esc to open Task Manager. Click the “Performance” tab and look at “Memory.” You’ll see total RAM and how much is in use.

While your game is running, switch back to Task Manager. Look at the “Processes” tab. Find your game’s .exe file. The “Memory” column shows how much it’s using. This gives you a baseline.

If your total usage is near 100%, you need to free up RAM. If it’s below 80%, you might have room to spare. The goal is to keep total usage under 90% during gameplay.

This is the core section. Follow these steps in order. Each one helps your game get priority access to your system’s memory.

Step 1: Close Unnecessary Background Programs

This is the easiest fix. Open Task Manager. Look at the “Processes” tab. Sort by “Memory” to see which apps use the most RAM.

Close web browsers like Chrome or Edge. They can use 2-4GB easily.
Exit chat apps like Discord or Skype if you don’t need them.
Close any file explorers, media players, or update services.
Right-click and “End task” on anything you don’t recognize.

Be careful not to close system processes. Stick to user apps. After closing, check your RAM usage again. You should see a noticeable drop.

Step 2: Disable Startup Programs

Many programs start automatically when you boot your PC. They sit in the background and eat RAM. To stop them:

Open Task Manager and click the “Startup” tab.
Look at the list. Disable anything you don’t need at startup.
Common culprits: Spotify, Adobe updaters, printer software, game launchers.
Restart your computer. You’ll have more free RAM from the start.

This step alone can free up 1-2GB of RAM. It’s a permanent fix, not a one-time thing.

Step 3: Adjust Virtual Memory (Page File)

Virtual memory is space on your hard drive that Windows uses as extra RAM. If you have enough physical RAM, you can still optimize this. But if you have less than 16GB, increasing the page file helps.

Press Win + R, type sysdm.cpl, and press Enter.
Go to the “Advanced” tab. Under “Performance,” click “Settings.”
Again go to “Advanced” tab. Under “Virtual memory,” click “Change.”
Uncheck “Automatically manage paging file size for all drives.”
Select your main drive (usually C:). Choose “Custom size.”
Set Initial size to 1.5x your RAM. For 16GB RAM, set it to 24576 MB.
Set Maximum size to 3x your RAM. For 16GB, set it to 49152 MB.
Click “Set,” then “OK.” Restart your PC.

This gives Windows more room to swap data. It won’t make games faster than physical RAM, but it prevents crashes when memory runs low.

Step 4: Set Game Priority In Task Manager

You can tell Windows to prioritize your game over other processes. This isn’t exactly allocating RAM, but it helps the game get CPU and memory resources first.

Launch your Steam game.
Press Ctrl + Shift + Esc to open Task Manager.
Go to the “Details” tab. Find your game’s .exe file.
Right-click it, hover over “Set priority,” and choose “High.”
Confirm the warning. The game will now get more system resources.

Note: Setting priority to “Realtime” can cause instability. Stick with “High.” You’ll need to do this every time you launch the game.

Step 5: Use Steam Launch Options

Steam itself has settings that can help with memory allocation. You can add launch options that tell the game how to use system resources.

Open your Steam Library.
Right-click the game and select “Properties.”
In the “General” tab, find “Launch Options.”
Type -high (without quotes). This sets the game to high priority automatically.
Some games also support -malloc=system or -heapsize 1048576. Check the game’s documentation.
Close the window and launch the game.

This is a permanent fix for priority. It works for most games. If you see issues, remove the option.

Step 6: Disable Memory-Hungry Windows Features

Windows runs many services that use RAM. You can disable some for gaming. Be careful not to break essential functions.

Disable Windows Search indexing. Go to Services, find “Windows Search,” set to “Disabled.”
Turn off visual effects. Go to System Properties > Advanced > Performance > Settings. Choose “Adjust for best performance.”
Disable Xbox Game Bar and Game Mode if they cause issues. Go to Settings > Gaming.
Turn off notifications and background apps in Settings > Privacy.

These changes free up 500MB to 1GB of RAM. They also reduce CPU load, which helps overall performance.

Advanced Methods For Allocating Ram

If basic steps aren’t enough, try these advanced techniques. They require more effort but can give better results.

Using Command Line To Set Affinity And Priority

You can use Command Prompt to set priority and CPU affinity for a game. This ensures the game gets dedicated resources.

Launch your game. Note its Process ID (PID) from Task Manager > Details.
Open Command Prompt as Administrator.
Type wmic process where processid="PID" call setpriority 128 (replace PID with the actual number).
This sets priority to “High.” You can also use 256 for “Realtime.”
To set CPU affinity, type start /affinity 1 game.exe (limits to CPU core 0).

This is for advanced users. Incorrect settings can slow down your system. Use with caution.

Adjusting Registry For Memory Management

You can tweak Windows memory management via the Registry. This is risky, so back up your Registry first.

Press Win + R, type regedit, press Enter.
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management.
Find “LargeSystemCache.” Set it to 1 to prioritize file caching.
Find “DisablePagingExecutive.” Set it to 1 to keep kernel data in RAM.
Restart your PC.

These changes can improve game loading times and reduce stuttering. But they may cause instability on some systems.

Common Mistakes When Allocating Ram

Many gamers make errors that hurt performance. Avoid these pitfalls.

Setting virtual memory too low. This causes crashes. Always set it to at least 1.5x your RAM.
Using “Realtime” priority. This can freeze your system. Stick with “High.”
Closing essential Windows services. This can break networking or audio.
Overclocking RAM without testing. This can cause instability in games.
Assuming more RAM always helps. If your game uses 8GB and you have 32GB, adding more won’t help.

Always test changes one at a time. If something goes wrong, revert the last change.

Hardware Upgrades For More Ram

Software tweaks have limits. If you still need more RAM, consider a hardware upgrade.

Most modern games recommend 16GB of RAM. For heavy titles or multitasking, 32GB is better. Check your motherboard specs before buying.

DDR4 RAM is affordable now. DDR5 is faster but more expensive. Match the speed and type to your system.

Installing more RAM is straightforward. Open your case, insert the sticks, and boot up. Your BIOS will detect it automatically.

After upgrading, you won’t need to allocate RAM manually. The system will have plenty to spare.
