A simple way to boost the performance of your computer is to add memory to the system.
How Much Memory Do I Have?
Find out how much memory is in the computer by examining the BIOS or operating system.
Open the System properties in Windows from the Control Panel and for Mac OS X, open the ‘About This Mac’ option from the Apple Menu.
How Much Memory Is Required?
Check your operating system and application programs. Often the operating system and application programs will have a printed minimum and recommended memory listing.
8GB memory card seems to be the best amount for laptops and desktops.
What Type Does Your Computer Support?
Look through the manuals that came with your computer or motherboard.
Most systems use DDR3 now and either 240-pin DIMM for desktops and 204-pin SODIMM for laptops.
Newer desktop PCs are starting to use the DDR4, 288 pin DIMM memory.
It is important that you know what type of memory upgrade you need as the types of memory are not interchangeable.
How Many Modules Should I Buy?
Ideally, you should buy as few modules as possible. Buy them in pairs for the fastest response time and efficient performance.
If you have a PC with 4 memory slots with just one of them being used with a 2GB module, you can add a single 2GB module to upgrade the total memory to 4GB. Alternatively, you can buy two 2GB modules and upgrade to 6GB.
Installing the Memory
Installing the memory cards typically involves just opening the case on a desktop or the slot on the bottom of a laptop.
