Static can damage computer parts, and can be imperceptible to a human. Ground yourself before starting, or use an antistatic wrist strap. You can ground yourself by touching a metal part on your computer case while it is unplugged from the wall. Simply being turned off does not remove any standby voltages, so make sure it's unplugged.
Locate your RAM sockets. Most motherboards have 2 or 4 RAM slots. RAM sockets are typically located near the CPU, though their location may vary depending on the manufacturer or model. Remove old RAM if upgrading.
If you are replacing old RAM, remove it by releasing the clamps on each side of the socket. Take your new RAM out of its protective packaging. Carefully remove the Ram from the shielded packaging. Grip it from the sides to avoid touching the contacts on the bottom or the circuitry on the board.
Line up the notch in the stick of RAM to the break in the slot. Set the stick into the slot and then apply equal pressure onto the stick until the clamps on the side click and lock the RAM in.
You may have to apply a fair amount of pressure, but never force it in. Make sure matching pairs are inserted into their matching sockets. Most are labeled on the board or by color, though you may need to refer to your motherboard layout diagram.
Make sure that they are facing the same way. Repeat the process for each stick of RAM you want to install. Remove dust using a bottle of compressed air. While you have the computer open, this can be a quick fix for general overheating and performance issues.
Compressed air cans are available at any office supply store. Do not blow air too closely at the computer. Close up the computer. Avoid running your computer while the panel is off, as this will actually reduce the cooling power of your fans. Plug your peripherals and monitor back in.
Power on the computer. Your computer should start normally. If your computer displays the self-test during the startup, then you can verify that the RAM has been installed correctly. If not, you can verify that the RAM was installed once Windows starts.
Check the RAM in Windows. Your RAM will be listed in the System section or at the bottom of the window. Operating systems calculate memory differently and some computers dedicate a certain amount of RAM to specific functions e.
For example, you may have purchased 1 gigabyte of RAM. The operating system may only display 0. The test may take a while to run, but will discover any errors and display how much is installed. Find out what type of RAM is required for your laptop computer. The type of RAM you can get is dependent on your computer. Before opening any panels on your laptop, make sure you are properly grounded to prevent damaging your components. Simply being turned off does not remove any standby voltages.
Unplug your notebook if plugged in. Remove the battery from the back of the laptop and then press the Power button to discharge any remaining power in the capacitors. Check how many sockets you have. There are usually a few different panels, so look for the one with the memory icon, or check you manual. You will need a very small Phillips-head screwdriver in order to remove the panel.
Most notebooks only have two sockets, while some only have one. Higher-end notebooks may have more slots.
This information may be listed under Memory Upgrade Information. Amount of memory installed - The current amount of memory installed on your computer. Go to Verifying how much memory can be added to verify the amount of memory installed. Maximum memory allowed - Subtract the amount of memory already installed from the maximum amount supported by the system to determine how much memory to get.
You can also buy the maximum amount allowed and replace the currently installed memory. Once you know the maximum for your system, check Maximum memory supported by operating system to see how much memory your version of Windows will support.
Use the lower of these two numbers as your maximum memory. Type of memory including speed - It is recommended to get the same type of memory same size, same speed, same manufacturer for each slot.
For best performance, get the fastest memory that the motherboard supports. Due to the variety of possible configurations, some motherboards 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 all DIMMs meet the requirements of for the motherboard the information listed in product specifications , have the same part number, are from the same manufacturer, and meet the basic memory requirements for your motherboard. If not, make sure that you can return the memory if it is not recognized by the system after you install the new memory.
Verifying how much memory can be added to your computer model Prior to upgrading memory, you need to verify how much memory you currently have installed to determine how much memory can be added. Use the steps for the BIOS version on your computer to find the exact memory configuration and how much memory can be purchased and installed. Select the BIOS version for your computer.
If you do not know which BIOS version your computer has, use the steps from one to see if the steps work. If not, use the other section. Click Power , press and hold the Shift key, and then select Shut down. When the first screen displays, immediately press the F10 key repeatedly, about once every second, until the Computer Setup program opens.
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 see the maximum memory the computer can hold, go to Finding memory information for your computer model.
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 motherboard. Usually, this is the maximum amount for each memory socket. For example, if the computer is capable of holding a maximum of MB 4 GB of memory and the motherboard has four memory slots, install 1 GB or less per slot. Immediately press the F10 key if your computer was built in or later came with Windows Vista or Windows 7.
Immediately press the F1 key if your computer was built before Windows XP or earlier. On some Compaq Presario computers before , press the F10 key at the logo screen. From the Main screen look at the Installed Memory line. This is the total amount of memory currently installed and the speed at which it is currently operating. Next, look at the Memory Bank information. The number of banks is equal to the number of memory slots on the motherboard.
The number next to each memory bank is the amount of memory for the module that is installed in that bank. If no amount is listed, that memory slot bank is empty. Example of BIOS memory information. Installing memory in your desktop computer Use the following steps to install memory in an HP or Compaq desktop computer.
After reviewing the following steps, if you are not confident in performing the installation yourself, contact an HP authorized distributor for technical assistance. The customer assumes all risk and liability for damages for any such installation or upgrade. You might find that your HP or Compaq computer is able to support a physical installation of 4 GB or more memory.
However, this maximum memory might be further limited by the operating system not being able to address the full range of physical memory. This limitation is present on all bit hardware and bit operating systems and is not limited to HP and Compaq PC systems or Microsoft software operating systems.
See Maximum memory supported by operating system for more information. Opening the access panel to install memory in your desktop computer Use the following steps to open the case:. The edges of metal panels can cut skin. Be careful not to slide skin along any interior metal edge of the computer.
