Windows tips & tricks

ReadyBoost

Get extra memory in a flash with ReadyBoost—watch this video to see how. (0:39)
Want a simple way to speed up your PC?
Just plug in a USB flash drive or card and let ReadyBoost borrow it. ReadyBoost is designed to help when your PC's memory is running low. Low memory can make your computer sluggish because Windows, which needs a place to stash data, turns to the hard drive. Flash memory offers a speedier alternative.
ReadyBoost works with most flash storage devices. In Windows 7, it can handle more flash memory and even multiple devices—up to eight, for a maximum 256 gigabytes (GB) of additional memory.

Turn ReadyBoost on or off for a storage device

ReadyBoost can speed up your computer by using storage space on most USB flash drives and flash memory cards.
Watch this video to learn how to turn ReadyBoost on or off for a storage device (1:32)

To turn ReadyBoost on or off

  1. Plug a flash drive or flash memory card into your computer.
  2. In the Autoplay dialog box, under General options, click Speed up my system.
  3. In the Properties dialog box, click the ReadyBoost tab, and then do one of the following:
    • To turn ReadyBoost off, click Do not use this device.
    • To use the maximum available space on the flash drive or memory card for ReadyBoost, click Dedicate this device to ReadyBoost. Windows will leave any files already stored on the device, but it'll use the rest to boost your system speed.
    • To use less than the maximum available space on the device for ReadyBoost, click Use this device, and then move the slider to choose the amount of available space on the device you want to use.
  4. Click OK.

Notes

Notes

  • If AutoPlay doesn't open, it might be disabled. For more information, see Troubleshoot AutoPlay problems.
  • For ReadyBoost to effectively speed up your computer, the flash drive or memory card should have at least 1 gigabyte (GB) of available space. If your drive or card doesn't have enough available space for ReadyBoost, you'll see a message telling you to free some space on it. For best results, use a flash drive or flash memory card with at least double the amount of available space as the amount of memory (RAM) in your computer.
For more information about how ReadyBoost works and what types of flash memory devices work with it, see Using memory in your storage device to speed up your computer.


Using memory in your storage device to speed up your computer

ReadyBoost can speed up your computer by using storage space on most USB flash drives and flash memory cards. When you plug a ReadyBoost-compatible storage device into your computer, the AutoPlay dialog box offers you the option to speed up your computer using ReadyBoost. If you select this option, you can choose how much memory on the device to use for this purpose.
When you set up a device to work with ReadyBoost, Windows shows you how much space it recommends you allow it to use for optimal performance. For ReadyBoost to effectively speed up your computer, the flash drive or memory card should have at least 1 gigabyte (GB) of available space. If your device doesn't have enough available space for ReadyBoost, you'll see a message telling you to free some space on the device if you want to use it to speed up your system.
You can enable or disable ReadyBoost for a specific flash drive or other removable storage device. For more information, see Turn ReadyBoost on or off for a storage device.

Notes

Notes

  • If your computer has a hard disk that uses solid-state drive (SSD) technology, you might not see an option to speed up your computer with ReadyBoost when you plug in a USB flash drive or flash memory card. You may instead receive the message, "Readyboost is not enabled on this computer because the system disk is fast enough that ReadyBoost is unlikely to provide any additional benefit." This is because some SSD drives are so fast they're unlikely to benefit from ReadyBoost.
  • In some situations, you might not be able to use all of the memory on your device to speed up your computer. For example, some flash memory devices contain both slow and fast flash memory, but ReadyBoost can only use fast flash memory to speed up your computer.


    Ways to improve your computer's performance

    Performance Information and Tools, the Windows Experience Index, and ReadyBoost all offer ways to help improve the performance of your computer.

    Tasks that can help improve performance

    Tasks in the left pane of Performance Information and Tools can help you improve your computer's performance.

    To open Performance Information and Tools

    • Open Performance Information and Tools by clicking the Start button Picture of the Start button, and then clicking Control Panel. In the search box, type Performance Information and Tools, and then, in the list of results, click Performance Information and Tools.
    Task Description
    Adjust visual effects
    Optimize performance by changing how menus and windows appear.
    Adjust indexing options
    Indexing options can help you find what you're looking for quickly and easily on your computer.
    You can search more efficiently by narrowing your search to focus on those files and folders that you commonly use. For more information, see Improve Windows searches using the index: frequently asked questions.
    Adjust power settings
    Change power-related settings so that your computer resumes from power-saving settings more efficiently, and adjust battery usage for portable computers.
    Open Disk Cleanup
    This tool deletes unnecessary or temporary files on your hard disk so you can increase the amount of storage space you have. For more information, see Delete files using Disk Cleanup.
    Advanced tools
    Access advanced system tools, such as Event Viewer, Disk Defragmenter, and System Information, that system administrators and IT professionals often use to solve problems. You can also view notifications about performance-related issues and what to do about them. For example, if Windows detects that a driver is reducing performance, click the notification to learn which driver is causing the problem and view help on how to update the driver. Issues listed at the beginning of the list are impacting the system more than issues listed further down the list.

    View details about your computer's capability

    The Windows Experience Index measures the capability of your computer's hardware and software configuration and expresses this measurement as a number called a base score. A higher base score generally means that your computer will perform better and faster than a computer with a lower base score, especially when performing more advanced and resource-intensive tasks.

    To view your computer's base score

    • Open Performance Information and Tools by clicking the Start button Picture of the Start button, and then clicking Control Panel. In the search box, type Performance Information and Tools, and then, in the list of results, click Performance Information and Tools.
      The Windows Experience Index base score and subscores for your computer are displayed on this page. If you don't see subscores and a base score, click Rate this computer. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation. If you recently upgraded your hardware and want to find out if your score has changed, click Re-run the assessment. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
    The Windows Experience Index is used by other software makers, so you can buy programs that are matched to your computer's base score. For more information, see What is the Windows Experience Index?
    To view detailed information about the hardware on your computer, such as processor speed, the amount of random access memory (RAM) installed, and hard disk size, click View and print detailed performance and system information.
