For desktop computers, shut down and unplug your computer and open the case. Please refer to your motherboard manual for proper order sequence for installing the memory. Installing memory in the incorrect order could result in lost potential memory performance, or in some cases failure to boot.
Remove the memory module as shown in Fig 1. Push the tabs (1) outward and the module will gently pop out of it's socket (2). Remove it completely from the socket.
To Install the new memory module see in Fig 2.
Push the tabs (1)that are at the ends of the memory socket outward and align the memory notches with the key of the memory socket (2), then push the memory down FIRMLY into the socket so the latches lock the memory in place (3).
If the memory has been installed but is not detected by the computer, repeat the process of removing and then reinstalling the memory to be sure the module is firmly seated. If the memory is still not detected, please contact Technical Support to be sure you have the correct memory part for your system.
For notebook computers, please note that before you remove/install memory in notebooks you need to shut down the unit and remove the battery pack and power cord. Push the memory in FIRMLY so that it makes good contact (it is important to push the memory in FIRMLY) into the socket before pushing it down to lock in place (See figures below) . Once the memory is installed please put the battery back in your unit and give it power using the power cord and not solely from the battery. If the memory has been properly installed and still not detected and you do have the correct memory you should make sure you have the most up to date BIOS* from your computer manufacturer's website.
*BIOS - Basic Input/Output System is installed on the computer's motherboard. It controls the most basic operations and is responsible for starting your computer up and initializing the hardware. It is data that is usually held in a ROM chip, which can be updated by "flashing" the BIOS as it's called. BIOS upgrades may correct errors, support new CPUs, support new hardware, including memory etc. BIOS updates are usually obtained by the computer's manufacturer's website.
