4 Common Misconceptions About Computer RAM

As you all know, RAM is an integral part of any PC or laptop. In other words, the computer can not run without RAM.

Not only that, but the importance of RAM also depends on your needs. If you need to play heavy games or use software that requires a lot of RAM, then it is crucial to buy and to be advised.

However, social networking sites nowadays have a lot of misleading advice and misconceptions about RAM, making people who do not know much about technology spend money to buy but the performance in return is not worth it. In this article, I will summarize 4 misconceptions about RAM that you guys often encounter when being consulted by some netizens. Therefore, you can avoid making mistakes for yourself.

1. Do not use 2 different sized RAM modules

Typically, motherboards on PCs or laptops are now equipped with 2 or more RAM slots. That is, if there is a need, you can completely upgrade later by buying 1-2 more RAM sticks to use. Convenient as it seems, but because of this that has created the common misconception among online “consultants” that it should not be shared with 2 different RAM modules or 2 different RAM brands. So should we “mix” shared RAM? The answer is yes, you absolutely can. The point is that it just won’t give you the best performance.

In fact, mixing two RAM modules with the same manufacturer, capacity, and frequency is highly recommended because it will give the best performance. If you plug in 2 different capacitors and want them to work best together, they will need to use the same amount of voltage, and their respective controllers also need to work together “harmoniously” on the motherboard. This is exactly why you should share 2 RAM modules of the same model and made it from the same manufacturer.

However, not so that you can not plug 2 other capacity bar. For example, at first, you have a 4GB RAM, later you feel that you do not have enough, but you do not have enough money to go up to 16GB so you only buy 1 more 8GB to go with the 4GB you have available. When plugged into the dual-channel, the computer will receive 4GB RAM of 4GB stick and 4GB RAM of 8GB stick running dual channel to increase performance. The remaining 4GB of RAM of the 8GB stick will run single-channel. In general, it will not be as fast as 2 RAM modules with dual-channel capacity but it will still be faster than the speed before you insert the 8GB stick.

The same goes for RAM modules that don’t have the same speed and latency. The computer will receive the lowest speed or latency of the RAM and apply it to both.

2. Don’t invest too much in RAM

This is enough RAM to run games and software, do not buy more” is also common advice on technology forums. So how much RAM is enough? The most satisfactory answer now is that RAM is never enough, whether it is enough or not depends on your needs.

Maybe the amount of RAM you have is enough to run the software, games, or applications you are using. However, that doesn’t mean you can’t run those applications faster with more RAM.

Most developers will program their programs so that the application only uses a fixed amount of RAM out of the total RAM you currently have. If you provide more RAM then that application will also use a fixed amount of RAM on the total amount of RAM you’ve added, but the amount of RAM used will now be more than before adding.

Besides, if you find that the computer is using somewhere 60% of the RAM you have, that doesn’t mean you don’t need more RAM. Running tasks require only 60% of the RAM because it leaves RAM in case you can open and use it later.

3. RAM capacity is the most important

Normally, a PC with a lot of RAMs somewhere between 32-64GB will automatically be considered by many to be very fast. However, this is not entirely true. RAM capacity is not everything.

Speed and frequency are some of the determinants of RAM performance. Like CPU, RAM also has clock. The higher the clock, the more data is transmitted in a second. The RAM frequencies that you usually see on the market are 2666MHz, and 3000MHZ, or 3200MHz.

Also, you should be careful in choosing RAM whose clock doesn’t match with the motherboard. If the RAM is clocked at 2000MHz but the motherboard only supports 1333MHz, your RAM will not be able to run at 2000MHz.

In general, you won’t be able to notice the difference between 8GB or 16GB of RAM. But if there is a higher pulse between 2 8GB RAM sticks and one has higher clock, you will immediately recognize the difference (of course, it depends on the task you perform).

4. You should empty RAM to improve speed

This can be said as the most common misconception of computer and phone users originating from applications, or RAM-releasing software, optimizing RAM, etc. like CCleaner on PC or RAM Cleanup, RAM Booster on phone.

In fact, emptying RAM that way doesn’t really improve your speed but sometimes even slows down the whole system. The reason is simple, the job of RAM is to be filled, the software and your operating system should be used as much as possible, and the remaining RAM is never used as wasted RAM.

Moreover, if you use the above software to free up RAM, it is likely that it will also delete the calculated data which is stored in RAM to help process data quickly. When you need it, RAM will have to load the data again, resulting in killing more time.
Instead of doing that, turn off unused applications manually if you want to free up RAM.
