This wikiHow teaches you how to free up Random Access Memory (RAM), which is the portion of your computer's or smartphone's memory that is dedicated to running programs. You can almost always free up RAM by closing open programs and, if necessary, restarting your computer or mobile. If you have an iPhone, there are a couple of additional tricks you can use to clear out the RAM; while most Android users shouldn't ever have to clear RAM, you can force-quit a RAM-heavy app if necessary, and Samsung Galaxy owners can use the Device Maintenance service to optimize their RAM usage.

  1. Clicking the X in the top-right corner of a program's window will usually close it. If you're trying to close a program that runs in the background, though, you can do the following:
    • Click the

      icon in the bottom-right corner of the screen.
    • Right-click the app icon for the program you want to close in the resulting pop-up menu.
    • Click Quit , then confirm if prompted.
  2. If you can't get a program to close normally, you can force it to quit:

  3. Start-up programs are programs which start when you boot up your computer. This can both make your computer's start-up process slower than necessary and crowd your computer's RAM. To disable these programs, do the following:
    • Press Ctrl + ⇧ Shift + Esc (or right-click the taskbar and then click Task Manager ).
    • Click the Startup tab at the top of the window.
    • Click the name of the program you don't want starting when you turn on your computer.
    • Click Disable in the bottom-right corner of the window.
  4. If you're still using Internet Explorer or even Microsoft Edge, you may be able to save some RAM by switching over to Google Chrome or Firefox.
    • Microsoft recommends using Microsoft Edge for best performance, but if you notice that Edge slows down your computer, you might want to try a different browser.
  5. Once you've disabled start-up programs, restarting your computer can help take care of any stored RAM:
    • Click Start
      Windows Start
      .
    • Click Power
      Windows Power
      .
    • Click Restart .

  • Question
    Is 2 Gigabytes of RAM enough to run CS:GO?

    Top Answerer
    2 GB is the minimum specified by Valve on their website; however, you may want to consider investing in more. You can always look up the minimum hardware specifications for a game on the publisher's website, a retailer's website, or other third-party hosts.

      Warnings

      • Most Android phones should never have their RAM reset due to how Androids conserve battery. By clearing the RAM, your Android will have to relaunch apps rather than just retrieving their stored information, thus decreasing battery life.
