Do you know what RAM is? What does RAM do on your computer? How Ram affects your computer’s performance? In this article, MiniTool Software introduces the information you may be interested in.

What Is Random Access Memory?

The full name of RAM is Random Access Memory, which is the hardware in a computing device. It holds the operating system, applications, and data that are currently using, so they can be quickly reached by your computer’s processor.


What Does RAM Do?

RAM is the main memory in a computer. It can read and write much faster than other storage devices such as hard drives, solid-state drives, or optical drives.

Random Access Memory is volatile. This means that the data can only be retained in RAM when the computer is turned on. When you power off your PC, the memory data will go away at the same time. When you reboot your computer, the operating system and other necessary files will be reloaded into RAM from an HDD or an SSD.

You see RAM can’t permanently store data, so you can treat it as a persons’ short-term memory. A hard drive can be considered as a person's long-term memory due to it can save files for you permanently unless you delete them.

RAM is focusing on immediate work. But it has a space limitation. It can only store a limited number of data. When it fills up, the processor will have to repeatedly go to your hard disk or SSD to overlay the old data in RAM with new data. Obviously, this progress will slow down or even freeze your computer.

How RAM Affects Performance?

What does RAM Affect?

When you open a program on your computer, the processor will give your device a command to retrieve the program from the hard drive or SSD. After that, your computer will need a workspace to manipulate the data and enable you to interact with it. This workspace is just your RAM.

When you don’t use the program temporarily, that program will be placed in RAM. When you open that program, the processor can access the information of the app faster and easily. This can save time for you. You should like this experience.

Is More RAM Better?

Every RAM has its capacity. In general, the more RAM your device has, the larger digital workspace you will have to deal with your programs. So your programs can run faster. If the capacity of your RAM is not enough, it can easily run out of memory when you open too many programs at the same time.

To solve the issue, you can increase virtual memory on your PC. This is an economical way. However, if your budget is sufficient, you can buy a larger RAM to add it to your device or replace the smaller one with the larger one.

All in all, RAM can affect your computer’s performance in these two main attributes: memory capacity and memory speed.

*Memory capacity

At present, the RAM capacities are divided into the following categories:

  • 2-4 GB RAM: This is the standard capacity of a RAM and it is usually used on Windows Vista and Windows XP. 2-4 GB memory can handle single apps on your computer. If it is not enough for you, you can add more RAM to improve your computer’s performance.
  • 4-6 GB RAM: This capacity is an average level for users. If you are not a gamer or high-end multimedia user, this is enough for you to deal with your daily usage like web browsing, working in Word documents, and emailing.
  • 6-8 GB RAM: This is a larger capacity for RAM. It is for casual gamers and basic multimedia users. If you have this kind of RAM, you can open multiple apps at once. Your computer performance will not be affected largely.
  • 8+ GB RAM: If you are a professional gamer or advanced multimedia users, this RAM should be your choice. This is a robust RAM capacity.

Now, you should know which capacity of RAM you should choose for your life and work.

*Memory Speed

Then, let’s talk about the memory speed,

The time it takes your RAM to receive a command from the processor and then read and write data is related to the memory speed. If you are using a faster RAM, it will be quicker for the memory to transfer information to another component. It will be more efficient at doing things with your computer

Well then, how to measure the RAM speed?

The RAM speed is measured in Megahertz (MHz), millions of cycles per second so that it can be compared to your processor’s clock speed. If you pursue efficient work, you'd better pay attention to this parameter.
