If you upgrade your RAM to 4 GB and check the system information box to see how much memory you have, you will find that it only says three gigabytes. This is true if you have a 32-bit processor. Does this mean something wrong with the chips in your computer?

Even though your computer’s motherboard may support 4GB, your OS may not report the full correct amount when you check the amount of RAM installed on your system. This is because, some of the memory gets allocated to support hardware devices such as the graphic card and network components. This memory is not displayed by the OS.

On some computers, the correct amount of memory will get displayed if you install Windows Vista Service Pack 1. This is because Windows Vista Service Pack 1 reports the exact amount of memory installed and not the amount of memory that is available to it.

32-bit operating systems do not support more than 4 GB of RAM. However, 64-bit operating systems can handle more RAM. For example, the 64-bit edition of Windows Vista Home Premium supports up to 16 GB of memory while Windows Vista Ultimate supports 128 GB of memory.

64-bit processors can handle more memory as they have a wider address-bus. However, you will need to install a 64-bit OS to take advantage of the full capabilities of the processor. 64-bit processors offer higher computing power and allow you to run more number of applications at the same time.

If your RAM chips are damaged, you will observe frequent crashes. In some cases, your computer may not even boot. In such cases, you will have to take the help of a computer repairman or replace the memory.

You can test your RAM by downloading Windows Memory Diagnostic utility from http://oca.microsoft.com/en/windiag.asp or MemTest from www.memtest.org or http://hcidesign.com/memtest/.

If your computer is running a bit slow, the best way to improve its performance is to add more RAM. Installing RAM is not a big deal. However, it are not so sure about it, it is best to take the help of someone who knows better or a professional computer technician.

Here are instructions on finding out how much memory your computer has and what type of RAM you should be purchasing:

1) If you are using a PC with Windows, click Start -> Control Panel -> Performance and Maintenance -> System. You can also right click on “My Computer” to find the amount of RAM present in your computer.

If you are using a Mac, find the Applications folder, double click “Utilities” folder and then double-click on “Apple System Profiler”. If you are using an older Mac like Mac OS 9 or older, select “Apple System Profiler” which is usually found in the Apple menu.

2) Check your motherboard or the company website to determine the number of RAM slots present on your motherboard. If a manual came with your motherboard, you can also refer to it. Also check the type of RAM and the maximum speed your motherboard can support. E.g. PC2100 DDR 133 MHz RAM.

3) Compare the memory currently installed with the maximum. You have two choices–add new memory sticks to empty slots or remove lower-capacity RAM and add a higher-capacity stick.

Tips:
==> Always install the correct RAM. Installing incompatible RAM can damage your motherboard.
==> If you are not comfortable with computers, take the help of someone who knows better or the local computer repairman.

Memory i.e. RAM is one of the main parts of the computer. RAM i.e. random access memory is where the computer stores instructions and data while performing operations on it. Since applications store data and instructions in RAM, the amount of RAM present in your computer determines the amount of data your computer can process at a time. The overall speed of your computer depends on the amount of RAM your computer has.

Here are instructions to find out the amount of RAM installed in your computer:

1) Rick-click on “My Computer” icon.

2) Select Properties.

3) Under the General tab, you can find the amount of RAM present in your computer.

Tips
==> If your computer is very slow, upgrading RAM i.e. adding more RAM to your computer can make it run faster.
