The RAM memory is the booster of the computer. The speed of program execution is based on this key component. To identify the right amount of RAM you need, you need to know the different characteristics of a RAM in order to properly assimilate its datasheet. This article is an explanatory guide which will allow you to choose a computer with a random access memory adapted to your needs.

The Role of Ram Memory in a Computer

This memory is also called volatile memory. It is mainly used to store temporary information. This information is automatically erased when the computer is turned off.

RAM is the acronym for Random Access Memory. Ram is one of the cornerstones of a computer. It comes in the form of a bar. The stored data disappears after processing the information. The ability of your computer to process data quickly, therefore, depends on the amount of RAM it has.

This so-called “flash” memory streamlines the functioning of the computer!

What is RAM Memory For?

The RAM memory is a storage space in which the data inherent in the files being executed or processed is loaded. Imagine that your computer does not have RAM memory, all the data would then be loaded from the hard drive. This would take considerable loading time. The computer to operate will look for the instructions to execute in its RAM memory. The RAM memory has an ultra-fast reading capacity which far exceeds that of a hard disk.

Why Choosing the Right Amount of RAM Is Important?

Without its volatile memory, a computer would not work. Since RAM memory is a key part of a computer’s hardware, you should think carefully about your choice for the good performance of your computer. Nowadays hard drives are getting faster and faster. The transition to SSD increases the performance of hard drives which still remain far from the ultra-fast RAM memories.

Your Usage Tells Your Choice

To choose a computer with a suitable RAM, you must take into account your usage needs. Indeed each user has his needs, and these needs must guide them in their purchase thinking.

Flash memories have evolved over time with features that make them more efficient one after the other. DDR (Double Data Rate, a technique for accelerating computer components) has been scrapped since 2005. DDR2 then replaced the previous model with its transfer rate twice as high. We had reached 200 MHz with DDR2. In 2007, DDR3 started by being marketed with an electrical consumption 40 times lower than DDR2 and a speed going up to 2133 Mhz.

Today we are at the end of DDR3 and the beginning of DDR4. The standard tends towards an intensive use of DDR4 at the beginning of this year 2019. New computers are very often equipped with DDR4. The latter is characterized by a considerable increase in performance compared to previous standards.


The frequency of RAM memory is its number of clock cycles per second. The higher this frequency, the faster the treatments. On most non-Apple models, it is possible to change or increase its RAM memory if you want to have a more responsive computer.

In the case of an upgrade, it is a good idea to check the compatibility of your motherboard with the RAM to guarantee operation. For better optimization, it is advisable to choose the highest frequency to which the motherboard can adapt.


Another feature of volatile memory is its latency. This characteristic indicates the execution time of requests or commands. The lower the latency the better it is for the performance of the computer.

First of all, a user who essentially wants to perform word processing and tasks related to office automation, for example, will not need a large amount of RAM. 4 GB or 8 GB of RAM is sufficient for the performance of these tasks and for the proper execution of these programs.

Another user profile is the “gamer”. The games need very intensive memory consumption; they should have a large amount of RAM for smoother operation. A minimum quantity of 16 GB is desirable for this type of use these days. Note also that the graphics card is a very important component to take into account when choosing a gaming laptop or a gaming desktop pc.

Finally, users who make video montages or graphic creations, need 16 GB or even 32 GB of RAM for computers to run at their full potential! Indeed, editing and visual creation software like some applications in the Adobe suite need these amounts of RAM to provide flawless renderings.

In short, the choice of RAM memory is dictated by usage! Choice of RAM depends on your needs, determine the amount of RAM you actually need. A suitable amount of RAM will optimize the performance of the computer for more fluid use.
