HP Desktop PCs - Upgrading memory (RAM) (Windows)

To improve system performance, you can upgrade the random-access memory (RAM) in your computer.

Before you purchase additional memory, make sure that you know the type of memory used by your computer, the maximum amount of memory for your computer, and the memory slot configuration.

Find memory information for your computer

To find memory upgrade information, see the specifications document for your computer.

To find product specifications, browse to the Product Information category on the support page for your computer model. Alternatively, you can search for your product specifications by searching HP Customer Support.

  1. On the HP Customer Support page, enter your serial number, product number, or product name in the Search field and click Submit. Alternatively, you can click Or, let HP detect your product to have your computer information detected for you.

  2. Click the link that matches your computer on the search results page.

  3. Click Manuals > Maintenance and Service Guide to review specific memory information for your computer. Make a note of these items when you are gathering memory information.

    • Amount of memory installed: The amount of memory currently installed on your computer. See Verify the amount of memory to install.

    • Maximum memory allowed: Subtract the amount of memory already installed from the maximum amount supported by the system to determine how much memory you need. You can also buy the maximum amount allowed and replace the currently installed memory. After you know the maximum for your system, check the maximum memory supported by the operating system to see how much memory your version of Windows supports. Use the lower of these two numbers as your maximum memory.

    • Type of memory (including speed): HP recommends that you install the same type of memory (same size, same speed, same manufacturer) for each slot. For best performance, get the fastest memory that the system board supports.

    Due to the variety of possible configurations, some system boards might not be able to properly configure memory if the array of dual in-line memory modules (DIMMs) contains a DIMM that is not from the same manufacturer, has a different CAS latency value, or has a different density value (high and low used together). Make sure that all DIMMs meet the requirements of for the system board (the information listed in product specifications), have the same part number, are from the same manufacturer, and meet the basic memory requirements for your system board.

Verify the amount of memory to install

Before upgrading memory, you need to verify how much memory you currently have installed to determine how much can be added. You can use the BIOS on your computer to find the exact memory configuration and how much additional memory can be installed.

Note:

Windows 10 has a minimum memory requirement of 1 GB RAM (32-bit) or 2 GB RAM (64-bit). The maximum memory requirement is 4 GB for 32-bit (Windows Home, Windows Education, or Windows Enterprise), 128 GB for the 64-bit version of Windows Home, or 2 TB for the 64-bit version of Windows Education or Windows Enterprise.

  1. Restart the computer.

  2. While the computer turns on, press the esc key repeatedly until the Startup Menu opens.

  3. Press the f1 key to open System Information.

  4. Make your memory calculations using the information in the Memory Size section.

    BIOS memory information
    • To find the total amount of memory that can be added, subtract the amount of memory currently in the computer from the maximum amount of memory the computer can hold.

    • To find the amount of memory per slot, divide the maximum amount of memory that the computer can hold by the number of memory slots on the system board. Usually, this is the maximum amount for each memory socket. For example, if the computer is capable of holding a maximum of 4096 MB (4 GB) of memory, and the system board has four memory slots, you can install 1 GB (or less) per slot.

Install memory in your computer

See the maintenance and service guide for your computer model for specific information on installing memory in your computer.

You can search for the maintenance and service guide on HP Customer Support.

  1. On the HP Customer Support page, enter your serial number, product number, or product name in the Search field and click Submit. Alternatively, you can click Or, let HP detect your product to have your computer information detected for you.

  2. Click the link on the search results page that matches your computer.

  3. Click Manuals > Maintenance and Service Guide to review specific memory installation procedures for your computer.

After reviewing the steps in the maintenance and service guide, if you are not confident in performing the installation yourself, contact an HP authorized distributor for technical assistance.

Note:

If someone other than HP installs or upgrades the memory, any damage caused by the memory or by a person trying to install or upgrade the memory is excluded from coverage under the product warranty. The customer assumes all risk and liability for damages for any such installation or upgrade.

Note:

You might determine that your computer is able to support a physical installation of 4 GB or more memory. However, this maximum memory might be limited by the operating system not being able to support the full range of physical memory. Windows 32-bit operating systems can support approximately 3.3 GB. This limitation is present on all 32-bit hardware and 32-bit operating systems and is not limited to Windows operating systems.

Troubleshooting memory installation issues

If the computer does not start properly after replacing the memory (the screen remains black and the computer turns itself off within a few seconds), or if there are memory errors (including beeps) after the computer starts, try the following options.

  • Reseat the new memory module.

  • Remove the memory module and use a can of compressed air to clean the groove in the memory module socket.

  • Check other cable connections inside the computer. Reconnect any cables that were disconnected or not securely connected.

  • Remove the new memory module and try starting the computer again. If the computer starts, make sure that you purchased the right type and compatible memory size. You can reference the memory module that originally came installed in the computer.

  • If possible, make sure that all memory modules in your configuration are from the same manufacturer and share the same model number.

  • If the computer still does not restart properly, remove the replacement memory, reinstall the original memory, and verify that the computer can operate in its original configuration.
