How to Check for Memory on a Computer

A computer's random access memory (RAM) is temporary data storage space that is able to transfer data to the processor much faster than the hard drive could alone. The amount of RAM installed on a computer is often an important factor in determining its overall speed at booting up and running applications. It is often useful to know exactly how much, and what type of memory, is installed to plan for computer upgrades and the check whether a computer meets the minimum memory requirements of different programs.

Things You'll Need

• Screwdriver

Instructions

Using the Direct X Diagnostic Tool

1. Click "Start," then "Run."

2. Type "dxdiag" in the run box and click enter.

3. Search the first page of the diagnostic window for the field "Memory." This field will display the total amount of RAM installed on your computer.

Using the CPU-Z Freeware Program

1. Download the CPU-Z system diagnostic tool (see Resources).

2. Double click the CPU-Z .exe file after downloading. This will produce a diagnostic window listing various information about your hardware.

3. Select the "Memory" tab. This tab will display your total memory, its running frequency, and the memory type.

4. Click on the "SPD" tab. This tab will display more information about each memory stick you have installed, such as manufacturer, part number and serial number. You can switch between RAM modules with a drop down menu in the upper left hand corner.

Physical Idenficiation

1. Turn off the PC and take out all plugs.

2. Use a screwdriver to open the computer's case. There are usually a few screws on the back of the case that hold on both side panels. The left side panel is usually the one that needs to be removed to gain access to the RAM.

3. Take out the RAM modules. The RAM modules are slender microchips which are almost always aligned between the CPU fan and the front of the computer's case. To get one out, press down firmly on two plastic locking clamps and it will pop out of place.

4. Inspect the RAM stick for identifying labels and information. Manufacturer, RAM type and other identifying information will likely be printed on each stick.

5. Reinstall the RAM and close the case. To reinstall the RAM sticks, align them the same way they were plugged in, and push down with even force. They will pop into place and the locking clips will automatically clamp around them.

Tips & Warnings

• CPU-Z is probably the fastest and easiest way to obtain detailed information about a computer's memory. If opening a computer's case, occasionally touch the metal case with your fingers to make sure static doesn't build up.
