Many RAM chips come with markings to indicate their type, speed and capacity.
The type of RAM a particular computer takes is dependent entirely on the motherboard. By inspecting the existing RAM and determining its type, if possible, the case is solved. Alternatively, the motherboard manufacturer will list the supported types and capacities of RAM in the user manual and on the company's website. Several vendors offer cross references to new RAM by computer make and model, and some automatic RAM scanning tools are even available.
Instructions
Inspect the Existing RAM
1. Power off the computer and open the case.
2. Connect one end of the anti-static wrist strap to your left or right wrist and clip the other end to the frame of the case.
3. Press outward on the plastic retention clips holding one of the RAM modules in place and press them downward until the module raises slightly in the socket. Pull the RAM straight up and out of the socket and inspect it for any markings or a label that indicates the type of RAM it is.
4. Replace the RAM module by sliding it back into the socket as indicated by the small notch and plastic tab that mate up when the module is inserted in the proper direction. Press firmly on each end until the module clips down fully into the socket and the retention clips snap into place on both ends.
Refer to Motherboard Information
5. Refer to the motherboard user manual that came with the computer and look for the section that explains which kind of RAM is supported on the motherboard and in what capacities and combinations.
6. Locate the brand and model number of the motherboard from markings on the board, which are visible when the case cover is removed and a flashlight is shined inside.
7. Log onto the Internet and browse the motherboard or computer manufacturer's website for details as to what kind of RAM is supported by the computer.
8. Call technical support for the computer and ask what kind of RAM the system takes.
BIOS System Setup Information
9. Restart the computer.
10. Press the required key to enter the system setup (BIOS) program when the system first boots and prior to the operating system logo appearing on the screen. The key is often displayed on the screen in the form of the message "Press (key) to enter setup" or something similar. Typical keys used are "Delete," "F1," "F2" and "F10." If the system does not enter setup, allow it to boot to the operating system and shut it down to try again.
11. Review the information on the main BIOS setup screen to see if the type of RAM is indicated there. Navigate to other screens using the keyboard arrows and "Enter" key to look for the type and amount of RAM installed. Typical locations include "System Information" and "General" categories.
Memory Vendor Websites
12. Launch a browser window and connect to a memory vendor website.
13. Enter the brand and model information into the interactive display to search for available memory upgrades for the computer.
14. Click the button for the automatic memory scanning tool if desired and follow the steps to install and run the utility to determine the type of RAM installed and the available upgrade options.
