RAM is the memory that allows your computer to operate quickly. Opening many programs, running various processes or accessing multiple files simultaneously will all require a fair amount of RAM. Complex programs like games or design software will use up even more. But it isn’t just the amount of RAM you need, the speed at which data flows in and out of your RAM is also important.
The faster your RAM can transfer data, the more responsive your PC will be. The performance of your RAM is measured in megatransfers per second, commonly abbreviated as MT/s. In addition to the overall speed, you can look at the timing performance of your RAM, often listed as Column Access Strobe latency (CAS latency). This measures the delay between your CPU sending a command to the RAM and the RAM actually executing that command.
Ideally you’ll want to stick with the same brand and clock speed of RAM sticks so they can work together as a team. This is because RAM working on the same channels needs to be in sync with each other, and if one of the sticks falls out of line it will slow down the whole kit. You can find kits of matching RAM in most stores, but you can also purchase individual modules from most retailers.
Unlike storage, which holds data long-term, memory is volatile, meaning that it gets erased when your computer turns off or shuts down. That is why it is important to keep an eye on your storage, so you don’t run out of space and start deleting things to make room for new files or apps. PC memory
