How much memory (RAM) do I have installed in my computer on Windows 7 / Vista

Sticks of memory (RAM) for Windows 7 or Windows Vista Memory, or "RAM", determines how much stuff can run on your computer at the same time; as a rule of thumb, the more memory you have, the faster and more responsive your PC tends to be. If you have a 32-bit version of Windows, your computer will not be able to use more than 3-3.5 gigabytes of memory, regardless of the amount of RAM you have installed. But you will be able to tell how much RAM is physically installed on your machine. For Windows 7 64-bits, the maximum amount of RAM you can install (and be seen by your computer) is up to 192 Gb, based on which edition of Windows 7 you are running. This tutorial explains how to find out the amount of RAM you currently have installed on your machine, and explain why you might not be able to see or use all available RAM, based on hardware problems or software characteristics.


How much RAM do I have on my computer

Follow these steps to find out how much memory is installed on your PC:

Note: If you do not see the right amount of RAM listed for your computer, it is probably a hardware problem: make sure that all sticks of RAM are properly fitted inside their respective slot. But it could be a software issue as well: since Windows Vista Service Pack 2, and for all editions of Windows 7, the correct amount of RAM will be displayed, even if your system cannot use the entire amount (a 32-bit version of Windows will not be able to use the full first 4Gb of memory, much less anything beyond that number).
