Desktop/PC Memory - Desktop Memory Upgrade

Most computer system specifications tend to list the system memory or RAM immediately following the CPU. There are two primarily aspects of RAM to look at in computer specifications: amount and type.  The rule of thumb is to determine if it has enough memory is to look at the requirements of the software you intend to run. Typically you want to have more RAM than the highest minimum and ideally at least as much as the highest listed recommended requirement.  The type of memory does matter to the performance of a system.  Beyond the type of memory, each memory type also has a related speed to that RAM as well.  One other thing that you might want to consider is how much memory the system can support.  Most desktop systems tend to have a total of four to six memory slots on the boards with modules installed in pairs.  Smaller form factor systems typically will only have a two or three RAM slots.  The way these slots are used can play a key role in how you can upgrade memory in the future.
