How do i choose the right memory for my computer?

Great Answer

Professionally Researched. (What's this?)

Computers are finicky about what types of Random Access Memory (RAM) they'll accept. When purchasing RAM, you must be certain to get the right type, otherwise it can lead to short-outs on your motherboard. In some cases, your computer won't accept it all.

Windows doesn't come pre-installed with software to detect memory types, but there are two free programs which can gather this information for you. Although their interfaces are different, they will both be able to quickly ascertain what type of RAM your computer uses.

CPUID

CPUID is entirely free to use and emphasizes an intuitive, easy-to-use graphical interface at the cost of a little more navigation. If you choose CPUID, download and install it. When you run the program, it will quickly scan your system. Afterwards, click the "Mainboard" icon and then choose "Physical Memory." The window on the bottom of the screen will give your RAM's statistics. Look beside "Type" to find out what type of RAM you're using, such as DDR2-533. This is the memory you need to purchase for an upgrade.

System Information for Windows (SIW)

System Information for Windows (SIW) comes in both freeware and Pro variants. For checking your RAM type, the freeware version will suffice. Although SIW's interface lacks the graphical intuitiveness of CPUID, it makes up for it with speed and ease of use. Download and install SIW and then run it. Click "Hardware" and then "Memory." The right-hand window will give you the statistics for your RAM. Of particular importance is the "Memory Type" and "Speed." For instance, the memory type might be DDR2 and the speed 533. This means you need to purchase DDR2-533 RAM.

Apple Computers

On Apple computers, it is much simpler to determine which memory to purchase. Under the Apple pulldown menu in the upper left of your screen, select "About This Mac." There you will see your current memory type and amount listed.
