RAM (Random Access Memory) is a storage medium which serves for temporary storage regarding to tasks in progress.

The RAM modules have to be plugged into the provided slots on the mainboard:

On the actual mainboard you usually find 2, 4 or 8 slots for memory modules. In order to be able to insert only modules which correspond to the intended specifications, the slots have a notch approximately in the middle.

 Like processors, also memory modules are also available with different clock rates. The higher the clock rate is, the faster is the possible transmission speed which can be reached.

Beside the clock rate, also the number of installed modules influences the amount of data transfer rate. Below you will find different descriptions depending on how many modules are installed:

  • Dual Channel
  • Triple Channel
  • Quad Channel

Dual Channel technology allows the system to use two memory modules at the same time. Therefore the maximum data transfer rate theoretically can be doubled compared with one module. Quad Channel technology would then theoretically provide quadruple transfer rate beside a single installed module.

Which technology is supported by the mainboard you are using can be read in the manual.

The higher the amount of memory is, the more files can be storaged temporarily. If the memory is runnig full the system has to outsource files to the existent SSD or HDD. Since these components are drastically slower than the memory, programms which are running will be slowed down.
