What is RAM?

Random Access Memory (RAM) is a type of computer memory that is able to be accessed randomly by the operating system and active applications. When a computer boots up, data for the operating is loaded onto the RAM to be accessed when needed. This same process is used when other applications are run. This is why the quality and performance of your RAM is integral to the performance of your PC.

What RAM do I need?

The type of RAM you need is mostly dependant on whether you have a laptop or desktop, but there are some other factors involved when picking out your memory.

If you're building or replacing RAM in a desktop, you'll most likely need DDR3 DIMM RAM. However, DDR2 RAM is a legacy type of memory that is still found in some systems, so if you're replacing or installing more RAM, be sure you know what type you have. DDR4 RAM is a newer memory type which is starting to gain notice and popularity, but is still mostly just used by private system builders. If you want to build a system that is on the cutting edge, you'll likely need to get DDR4.

Laptops are a little different in that they just can't fit DIMM modules, but instead require SODIMM modules (the "SO" stands for "small outline"). SODIMMs are simply the little brother of DIMM modules, and perform the same functions with effectively the same performance. You'll be a bit more hard pressed to find anything but DDR3 in a laptop anyone is using today, but there are still some running that use DDR2.

How much RAM do I need?

For most users, 4GB to 8GB of RAM is plenty, but gamers and performance enthusiasts will often install up to 32GB or more to make sure their system has as little slow-down as possible while they're playing online, recording game footage, overclocking, rendering 3D models, or other hardware intensive functions.

Most computers today run on a 64-bit system, but some are still 32-bit. The big issue here is that 32-bit systems are only able to support up to 4GB of memory. It's mathematically impossible for them to run any more than that. However, most 64-bit systems support 16GB if not more. For instance, Windows 7 Professional caps supported memory at 128GB.
