Upgrading RAM ?

Unfortunately upgrading RAM memory is not like installing new operating system like windows, but still its not too difficult once you do things in right way. Installing a new ram is really easy but it will will work with your computer is a question in itself which you need to make sure that you get the answer, as an incompatible means firstly it may now fit into your computer motherboard slot or if it fits and runs on a frequency which is not supported by your motherboard than it will result in decreased life of the new RAM memory.

Things To Take Care While Upgrading RAM Memory

Is your Older RAM DDR, DDR2, or DDR3 memory

First you need to find out which technology RAM is already inside your computer, is it a DDR SD RAM, there are different generations of RAM like DDR, DDR2, or DDR3 memory till now, and all these different technology RAMs are slightly different in build so that means that if your computer motherboard supports DDR2 it wont support adding a DDR3 as it wont fit into the slot on motherboard. Same way round for DDR and DDR3 motherboards.

In order to find the RAM type already in your computer you can download the CPUZ [ free tool ] it will show you the memory type under the memory tab once you install and run it on your computer as you can see in the image below.

Another similar software that will help you find the Type of RAM installed on your computer is called System Information for Windows [ Scroll down to the bottom of the page for the free home edition of this tool ].

Speed of RAM Memory in Mega Hertz Does Your Motherboard Support It?

Another most important thing to consider while upgrading the memory is to find out the frequency speed of the current installed memory on your computer, through both of the tools mentioned above you can find this information. It will be either listed as DRAM Frequency or Speed and both on Mega Hertz.  As you can see in the snapshots above, the speed is 533 Mhz this means that I can upgrade to any DDR3 RAM memory upto 533 Mhz.

Using both of information including Type of RAM and Speed in MHz you will be able to decide the correct memory upgrade.
