Do you know Laptop RAM vs Desktop RAM, If not, don’t worry, this guide will help you with it?

The RAM is the random access memory and it is the most important component of any device. It is very important to choose the best RAM for your laptop because it is the most essential component that helps you to perform better in your work.

It is recommended that you always keep your RAM healthy and don’t use it up. So, here we have discussed some of the differences between laptop RAM and desktop RAM. RAM is the part of the computer that stores the programs and data. So, when you open your laptop or computer, then the first thing that comes to your mind is the RAM.

RAM is one of the most important components of a laptop and it is the most expensive one. Now, let’s discuss some of the similarities and differences between laptop ram and desktop ram. Differences

The size of RAM depends upon the device. Laptop ram is comparatively smaller than desktop ram and desktop ram has more memory. There is a big difference between laptop ram and desktop ram.

Desktop RAM (DIMM)

The dual in-line memory module (DIMM) is used in desktop computers. This is a type of computer memory that has several chips on a single circuit board. It is capable of transferring data quickly compared to other types of memories.

The pins that connect the 64 bits of memory to the board are native to it. The single in-line memory module that uses a 32-bit memory path is slowly being replaced by the DIMM. Since it uses a 64-bit bus, it is possible to double the data transfer at the same time.

They are more compatible with the majority of modern computers that have a 64-bit data width. If you want to get the same speed of data with a sim module, you have to install it in pairs which take up more space on the board.

The DIMM is categorized as a dynamic RAM. For it to not lose its contents, the memory needs to be refreshed constantly. Dynamic Random Access Memory is the most common type of primary memory and is less expensive than static memory.

Laptop RAM (SO-DIMM)

A small outline dual in-line memory module, also known as SO-DIMM, is a type of RAM used in laptops. It uses integrated circuits, which makes it much smaller than regular DIMMs.

Since they have limited expansion space, laptops and notebooks that use Mini-ITX are usually the ones with SO-DIMMs. It is possible to be in networking hardware such as routers and high-end office printers.

Common problems laptop builders faced were specifically addressed by SO-DIMMs. Since most laptops need to be small and portable by design, large RAM chips like DIMM wouldn’t be ideal since they are large and may not fit into the overall design of the laptop. Using large memory chips like DIMMs would increase the laptop’s size making them unbearably bulky.

Similarities Between Laptop RAM and Desktop RAM

If you decide to swap, you might be wondering if the two types of memories are compatible. There is a chance that a very old laptop and desktop memory can be swapped back and forth.

The number of pins on the memory needs to be compatible with the slot on the board. After the successful transfer of a laptop memory to a desktop, the transfer speeds and transfer rates remain the same.

If you intend to use a laptop with a desktop that uses DDR3 then it is important to make sure that it meets all the requirements. The two need to be compatible with speed being one of the key factors. The speed requirement of a computer system can be determined by looking at the board or using a scanning device.

Both Cannot Be Expanded More Than The Capacity Of The Motherboard

Most people love gaming and are fond of designing on computers, so expanding a laptop memory is a common thing. Some computers allow for an extra slot for expandability, while others only allow one slot. Those with a single slot can only be replaced with bigger memory. The computer’s board must be compatible with the new memory to expand the computer’s RAM.

Differences Between A Laptop RAM And Desktop RAM

Laptop RAM vs Desktop RAM

The differences between the two types of memories can be seen in their form factor. Some differences include the following:

Laptop RAM Is Smaller In Size Than Desktop RAM

The form factor is the main indicator of the differences between laptop and desktop RAM. The physical size and pin configuration are what that is. A desktop has about 100, 168, and 184 bits of memory.

There are over 200 pins, the total number is over 200 pins. The length of the RAM is about 4.5 inches. A laptop has a total of 72, 100, and 104 RAM. The total number of pins on the laptop is more than 200. The average length of the laptop’s RAM is 3 inches. This means that the laptop’s memory is much smaller than the desktop’s.

Newer Versions Of Laptop Memories Are Incompatible With Desktops

The general rule for making RAM for computers is that the shorter modules are designed for laptops, while the bigger modules are for desktop computers. You cannot use laptop RAM on a desktop slot because the two are not interchangeable.

Since the number of pins on the RAM should match the holes on the computer slot, you should guide yourself by the form factor. The modern-day processor speeds are not catching up with the modern-day RAM speeds.

The slots on the machine that has a different generation of RAM sticks will not be physically attached to the RAM sticks. If you want to find out if your laptop or desktop computer system is compatible with the RAM, you can look at the sticker on the stick.

One of the reasons why the two memories are incompatible is that they use the same type of memory. DIMM stands for dual inline memory modules and they are known as SO- DIMM. Small outline dual inline memory modules are referred to as SO- DIMMs.

Types There Are Two Types Of RAM:

DDR3 and DDR4 are more powerful as compared to DDR3 is an older version of ram but it is still used in some laptops. DDR4 ram is used in new laptops and is more powerful.

Frequency In a laptop, the frequency of ram is different from that of desktop ram. The frequency of RAM in a laptop is 2133 MHz whereas on a desktop it is 2666 MHz. It means that the speed of the ram in a laptop is faster as compared to that in a desktop.

Price The price of ram depends upon its quality and type. If you are buying a laptop then you should always buy the best ram available in the market.

Speed The speed of the ram depends upon the device. If you are buying a laptop then you should always choose the best speed for your laptop. If you are buying a desktop, then you should buy the maximum ram available in the market. Similarities

Compatibility RAM is compatible with all types of devices like laptops, desktops, smartphones, tablets, etc.

Security Security is very important and it is recommended that you use only the best ram available in the market.


These are some of the differences between laptop ram and desktop ram. You can make your decision after reading these points. I hope this article was helpful to you and I wish that you will have a healthy and happy RAM.
