Laptop Ram VS Desktop Ram

Random Access Memory (RAM), or system memory, is vital in all computers. Laptop and desktop systems use different types of RAM; There are two main types of computer memory: laptop ram and desktop ram. But what’s the difference? In this article, we will discuss laptop ram vs desktop ram.

RAM is a computer memory that temporarily stores data. It stands for Random Access Memory, and your computer needs to run.

Laptop ram and desktop ram both serve the same purpose – they store data while your computer is running – but there are some key differences between them.

It’s just like your laptop’s or desktop’s hard drive: the hard drive is used to store data permanently, while RAM (random access memory) is used to store data temporarily.

About Memory or RAM

Memory is an essential component of any computer. It is the part that stores all the data and instructions that are accessed by your processor, allowing you to carry out tasks and operations.

RAM (Random Access Memory) and main Memory are other terms for system memory. .and it can be accessed randomly.

RAM is the working memory storage area, allowing programs to run quickly. It stores all the temporary data the processor is accessing, and a computer needs to function correctly.

Desktop RAM & Laptop RAM: An Overview

While RAM essentially does the same thing between laptops and desktops, there are a few key differences that you’ll want to be aware of. 

The main difference between a desktop’s and a laptop’s RAM is physical size and speed.

Laptop Ram ( SO DIMM)

Laptop Ram

A type of random access memory. It uses integrated circuits and is smaller than typical Dual Inline Memory Modules.

Laptop RAM is a small, lightweight, low-power RAM specifically designed for laptop computers. It usually comes in the form of SO-DIMM (Small Outline Dual Inline Memory Module) memory modules, which are smaller than desktop RAM sticks and can fit into most laptops.

They need more expansion space. Notebooks and laptops with Mini ITX motherboards can use SO-DIMMs. Additionally, they can be found in networking equipment like routers and high-end office printers.

Laptop RAM is often more expensive than desktop RAM, but its low power consumption and smaller size mean it is ideal for portable computers.

Due to their smaller size than standard DIMMs, SO-DIMM chips are more flexible in designing laptop memory slots. They are simple to upgrade because they are placed in a convenient location on the motherboard.


Here are some examples of SO-DIMMs 

  • DDR3 SO-DIMM – 1066/1333/1600 MHz
  • DDR4 SO-DIMM – 2133/2400/2666 MHz
  • LPDDR3 SODIMM – 1866/2133 MHz
  • LPDDR4 SO-DIMM – 2400/2666/3200 MHz

Desktop RAM (DIMM)

Desktop Ram

Desktop RAM is more significant than Laptop RAM and usually comes in a DIMM or Dual Inline Memory Module with pins on both sides of the circuit board for connecting it to the motherboard.

Computers have larger memory modules than laptops because they are designed to be more powerful.

It is typically faster than Laptop RAM and comes in larger memory capacities, ranging from 4GB to 64GB or more, depending on the user’s needs.

This can transport data more quickly than other kinds of Memory. It is also more reliable than Laptop RAM because it has a longer lifespan, meaning it can be used over multiple generations of hardware.

Desktop PCs demand a lot more RAM than their laptop counterparts. Desktops use large internal memory banks to run the operating system and often have several hard drives and other peripherals, such as graphics cards and sound cards, that all require access to Memory.

In terms of performance, Desktop memory offers higher clock speeds and more significant amounts of cache memory, allowing faster data processing speeds and making it ideal for gaming or other intensive applications.

The DIMM type consists of many memory chips on a single circuit board. DIMMs are the standard memory type usually used in desktop computers.

Additionally, desktop RAM typically offers better support for overclocking, enabling users to push the hardware beyond its default settings to achieve higher performance.

DIMM is gradually switching SIMM (single inline memory module), which uses a 32-bit memory path. Dual inline Memory can transfer twice as much data because it uses a 64-bit bus.

DIMM can be categorized as dynamic RAM (DRAM). Dynamic refers to the requirement to often refresh Memory in order to prevent data loss.

DRAM is the most common type of primary Memory, which is less expensive than static Memory.

Computer Memory

Some examples of DIMMs

  • SDRAM (Synchronous Dynamic Ram)

Differences between Desktop RAM and Laptop RAM

Have many differences in size, compatibility, and memory slots. Desktop Computer RAM performs better than Laptop Computer RAM. 

Differences between Desktop and Laptop RAM


The size of Laptop RAM is much smaller than Desktop RAM. Laptop RAM sticks are usually from 0.25 inches to 1 inch, while Desktop RAM sticks range from 2.5 inches to 3 inches.

The overall number of pins on a desktop RAM module is 240. While memory modules in laptops house 204 pins.

The size difference is the physical length and the pin configuration. Laptop RAM modules are roughly 50% of desktop RAM modules.


Desktop memory is only sometimes fully compatible with a laptop. Laptop RAM is usually slightly different from desktop RAM, especially in form factor. Laptop memory often comes in smaller SO-DIMM or SODIMM modules, while desktop memory typically uses larger DIMMs.

Laptops also have stricter power and heat dissipation requirements, which can further limit compatibility.

Also, laptop modules need less voltage to operate, so they won’t work or damage a desktop computer.

The structure of the Memory is much different between laptop and desktop RAM.

Bios Support

A desktop computer’s RAM can range from 1GB to 8 GB. On the other hand, Laptop RAM is limited to 4GB. Laptops and netbooks must also include BIOS support for their RAM to function properly.

RAM is essential for running any operating system, desktop, or laptop computer. High-end software also benefits from high RAM.

Memory Slot

Different laptop systems and workstations have different memory slots. Laptops typically have just one or two memory slots, so it is impossible to increase their RAM. This is due to the small space available on a laptop’s body.

While desktops usually have four to eight. You can add additional RAM to expand the Memory. Editors, gamers, and anyone who enjoys multi-tasking and interactive tasks can do this.


Upgradability is a major concern for enthusiasts. Many laptop manufacturers need help to replace or upgrade laptop components. Some require you to send the laptop back to them or void your warranty.

Laptop manufacturers follow the path where users get limited control of their machines. The upgradability factor is partially related but is something to consider if we compare the two.

With a desktop, you can easily unscrew the side panel, pop in some new memory (or even a new graphics card), and be up and running again in no time.


Laptop RAM has a lower capacity than desktop RAM. This is useful when working on large files or with many images and videos.


Desktop systems can have multiple memory banks installed simultaneously to allow for more RAM. Laptop systems often have a single memory slot, which can limit the amount of RAM you can install in them.


Laptop RAM is also designed for low-power consumption, as laptops run on batteries and use less power than desktops. This means that laptop RAM can be used in a desktop computer, but not the other way around.

The voltages required for standard desktop RAM are generally between 1.5V and 2.5V. This allows a greater range of manufacturers and models to be used in one system.


Both desktop and laptop RAM provide similar functionality – allowing a computer to work as quickly as possible.

RAM is where the CPU can temporarily hold and access your data, which then passes it to other components.

If you expand the available RAM, Your system will have more storage space and use disk space less frequently.


Laptops are often more expensive than desktops, and laptop RAM is typically more costly.

The laptop RAM’s price is higher than that of the desktop RAM. Laptop RAM prices for 4GB and 8GB are lower because of the small size of DDR4 Memory.

Technical Details

The bandwidth of desktop modules is typically lower than that of laptop modules. Because they can be made more prominent and, therefore, can store and transmit more information per module.

They also have a higher latency, meaning They may require more time to retrieve and process large blocks of information.

The highest specification you should consider for desktop and laptop memory is capacity. However, this only tells part of the story because modules come in different types, speeds, and latencies, impacting performance.

Desktop vs Laptop Memory – The Similarities

 Similarties between Desktop vs Laptop Memory

Laptop and desktop memory are similar. Computer and laptop memories both employ the same technology.

Both types of RAM speeds are measured in MHz and GHz to indicate how quickly information can be accessed.

Voltage is the amount of electricity needed to work at its best, and both memories use 1.5V power.


How to Convert Work Laptop to Personal?


In conclusion, both types of Memory have pros and cons. It depends on the person’s needs and what type of Memory they should get.

Laptop ram might be more expensive, but it is more convenient because it is smaller and doesn’t require additional hardware.

Desktop ram is cheaper and easier to find but can be challenging to install.
