How to Choose RAM for PC and Laptop

If you buy a new laptop, at least 4GB of RAM is pre-installed, which means that RAM extension is not required immediately. Although 4Gb of RAM is not enough, it is still sufficient for many applications.

However, there are circumstances where a PC or laptop seems to be short of internal memory. For instance, when the computer responds slower than usual and the hard disk is running extremely heavy.

In such a situation, when PC can’t perform the usual task smoothly, It’s essential to add extra RAM sticks. But considering lots of option available, it could be tough to decide which RAM to select. Therefore, we decided to guide you exactly how to choose RAM according to your PC or laptops’ motherboard.

In case you want to save few bucks, we have a complete guide prepared on how to buy best used RAM for your computer.

How To Choose RAM for PC and Laptop?

We have concluded a few factors that are necessary to choose RAM for your PC or laptop. By going through them, you will be able to understand how to choose RAM for your computer easily.

Internal Vs. External Memory

First of all it’s important to understand the difference between memory types. Computers have two types of memory, Internal and External memory. External memory refers to the disk drives located in our PC, such as Hard disk, SSDs, and also USB sticks. While Internal memory is Random Access Memory (RAM) of the PC.

The primary differences between Internal memory and External memory are:

  1. External memory retains data when we turn off the PC, while internal memory deletes all data as soon as the PC is switched off.
  2. Internal memory is far quicker than external memory.
  3. As computer users, we cannot save anything in the internal memory.

RAM stands for Random Access Memory and it is managed by the memory controller in PC, and RAM memory is always accessible by processor to store or retrieve data.

However, In case of internal memory deficiency, external memory activates to store the data as per the processor request.

At this moment, the computer suddenly reacts and performs a lot slower than normal.

This issue can be solved by adding more internal memories. You may also see some other advantages as mentioned:

  1. Program runs better and responds faster to commands.
  2. Startup of programs is faster.
  3. Multiple programs can run simultaneously.
  4. The overall speed of the computer is increased.

Until you find best RAM for your PC or Laptop, here is the list of 2GB RAM Games and 4GB RAM Games to enjoy on limited specification.

How much RAM do I need?

By finding this answer, you’ll know exactly how much RAM is suitable for your requirement.

Windows 10 requires a minimum of 2GB to perform efficiently.

Practically, 4GB of working memory is all you need, if you want to do standard things comfortably, such as surf the web, e-mail, compose something in Word, and perform some Excel calculations. And rarely open many tabs on the browser.

8GB of memory is suitable primarily when you frequently use multiple programs simultaneously.

You only need to think about 16GB of memory when you play games that seriously affect your PC’s performance. In such a situation, consider the amount of memory recommended by the manufacturer of the game.

Even 32GB of RAM is compatible with a PC. But this amount of RAM is only worth considering when you edit huge RAW photo files and high-resolution video files every day.

How To Stop PC from USing So Much RAM?

If you start to monitor your PC’s working memory with below-given steps, you will immediately notice possible irregularities.

Irregularities occur on PC mostly when installed RAM is insufficient to perform the given task, and external memory comes in to do the job.

To check the operating memory, follow the steps below:

  1. Start the PC
  2. Open multiple programs that you generally use.
  3. Then open all the softwares that you usually utilize.
  4. Right-click on the toolbar and select the Task Manager option from the open shortcut menu.
  5. In the Task Manager, click on the Performance tab.

  1. You will see an overview of the PC components that influence performance to a significant extent. Furthermore, you will be able to see exactly how much RAM your PC currently owns.
  2. Then spend 10 to 15 minutes doing work on your PC as you generally do.
  3. Now check the taskbar and see how much memory your PC is currently using if it is more than 85%. Indicates your PCs RAM is insufficient to perform daily tasks.
  4. Close all programs in use and rest the PC for at least one hour.

Then check the memory graph and also the WiFi graph. Note: The WiFi Chart displays Internet usage and other traffic on the PC.

If during this hour of non-use, a lot of activity occurred in the memory, processor, and or via WiFi / Ethernet, it confirms the likelihood of an infected PC. In the form of viruses, spyware, and other malicious software.

In this situation, we recommend a thorough scan of your PC by a spyware scanner.

Which RAM should I use?

RAMs are usually in the form of memory modules, and chips are mounted on these memory modules. Furthermore, these memory modules have a mounting strip for easy fitting into the RAM slots.

PCs use RAM type Dual Data Rate (DDR) memory. The most common of them are DDR3 and DDR4 memory modules.

You can download CPU-Z to check what kind of RAM module is supported by your motherboard, it also shows all the information about your current RAM.

DDR3 memory modules come in sizes 4GB and 8GB. And DDR4 modules in 4, 8, 16 and even 32GB of sizes.

RAMs from different manufacturers are compatible with each other in one PC. But it’s not a good practice as it may create less stability between RAMs, which results in compromised performance from PC.

Which type of RAM you can use in your PC depends on the supported type of motherboard. You can find this information on your motherboard manufacturer’s website.

When expanding RAM, always expand memory with the fastest type supported by the motherboard and prefer to buy memory modules from a reputable brand such as: Corsair and Kingston.

Dual and Quad Channel Memory Modules

Many motherboards provide the possibility to place memory modules in pairs, in a Dual or Quad Channel Memory setup. By placing internal memory in pairs of two and three, the performance of the system can increase by 10 to 15 percent.

Both the motherboard and the memory modules used must of course support Dual Channel Memory.

Normally, a memory module has a transport line that is 64 bits in size. Which means that data can be transported in chunks of 64 bits over the line.

However, when using the Dual Channel Memory technique, the transport line of a memory module becomes 128 bits in size. Which means that now data can be transported in chunks of 128 bits over the line.

Similarly with Quad Channel Module, Data can be transported in 192 chunks of bits over the line.

SO-DIMM Memory Modules

In order to extend laptops’ RAM, you need SO-DIMM type of memory modules. These memory modules are specifically designed to fit in tight spaces. SO-DIMM modules are smaller than ‘normal’ – but the performance is no less.

Once you find the right memory type and size to expand the RAM in your PC or laptop, installing time depends on the kind of computer you own among them.

PC is straightforward; all you have to do is remove the cover and fix RAM sticks in boards’ slots which could hardly take 10 minutes.

On the other hand – Laptop can take about 30 to 45 minutes and sometimes may require technical knowledge to open up and install a RAM stick.


Choosing the best RAM is not a tough task if you have sufficient knowledge. First, check with the help of the mentioned steps if your PC is not infected as it can affect profoundly on performance. If everything’s perfect, find out what kind of RAM module is supported by your motherboard and select RAM accordingly. It’s better to use a dual-channel or quad-channel memory as many latest games and software manufacturers recommend it – ofcourse, if your board supports it.
