Your system memory is an important part of the main processing subsystem of the PC, tied in with the processor, cache, motherboard and chipset. The amount and type of system memory you have is an important contributing factor to overall performance. This is an important point that is often overlooked. Newer programs require more memory than old ones. More memory will give you access to programs that you cannot use with a lesser amount.
Bad memory is a leading cause of mysterious system problems.
Ensuring you have high-quality memory will result in a PC that runs smoothly and exhibits fewer problems. Also, even high-quality memory will not work well if you use the wrong kind. There are many different types of memory available, and some are more universal than others. Making a wise choice can allow you to migrate your memory to a future system or continue to use it after you upgrade your motherboard.
