Why are SODIMMs well suited for laptops?

SODIMMs, or small outline dual in-line memory modules, have become an increasingly popular choice for laptop computers and other mobile devices.

While they are much smaller than traditional desktop RAM sticks, SODIMMs offer the same high-performance computing capabilities but with a fraction of the size requirement providing powerful performance in an unobtrusive package.

But why make the switch to SODIMM RAM? In this guide, we will explore just how exactly these compact memory modules can benefit your laptop’s performance and why they make such a great choice for most users.

Read on to learn more.

What is a SODIMM?

A Small Outline Dual In-line Memory Module (SODIMM) is a type of RAM typically used in laptop computers, netbooks, tablets, or other small form factor computers.

Unlike desktop PCs which use standard DIMMs (Dual In-Line Memory Modules), the space constraints of these devices limit their maximum RAM capacity by using SODIMM modules.

Usually, SODIMMs are much smaller than regular DIMMs and contain fewer pins as well. Similarly, due to the limited real estate inside laptops and other slim devices, large cooling solutions can’t be used like a typical desktop PC so having SODIIMMs that generate less heat is an important factor when selecting memory upgrades for these machines.

If you’re looking to upgrade your laptop or netbook RAM then make sure you get the correct size of SODIMM sticks; otherwise, your attempts may be futile.

How do I know if my laptop uses a SODIMM?

Identifying whether or not your laptop uses a SODIMM memory module is an important step when it comes to upgrading RAM. By using these three simple steps, you can easily determine if you are using a SODIMM memory module in your device.

Step 1: Check Your Manual or Manufacturer’s Website

The best way to determine if your laptop uses a SODIMM memory module is by checking your user manual or the manufacturer’s website.

Many laptops have specific requirements for RAM upgrades, so this will give you the most accurate information about what type of memory module you need for your laptop.

Step 2: Identify Your Laptop Model Number

You should also identify the model number of your laptop. This can usually be found on the bottom of the case or in the battery compartment.

Once you have identified your model number, search online for more information about that specific model and its specific RAM requirements.

This will help you determine which type of memory module you need.

Step 3: Measure Your Existing Memory Module

Once you have identified which type of memory module is required for your laptop, it is time to measure your existing one. Measure both length and width in millimeters (mm).

If these measurements match those of a SODIMM then that confirms that this is indeed the type of memory module used in your device.

What are the benefits of using a SODIMM?

There are many benefits to using a SODIMM in your computing needs.

Improved Performance

The primary benefit of using a SODIMM is improved performance.

The module is designed to provide better overall performance than traditional desktop memory modules, making your computer faster and more responsive.

This is especially important in applications where speed and responsiveness are essential, such as gaming or video editing.

Compact Size

Another benefit of using a SODIMM is its compact size.

The module is designed to be much smaller than traditional memory modules, making it ideal for laptops, tablets, and other devices with limited space for components.

This makes it easier to upgrade your system without having to worry about the size of the module you’re installing.     

Cost Efficiency 

Finally, SODIMMs are also cost-efficient.

Because they are smaller and require less power to run than traditional desktop memory modules, they can often be found at lower prices than their larger counterparts.

This makes them ideal for those who need to upgrade their systems on a budget.

Can I upgrade my laptop’s memory with a SODIMM?

When it comes to upgrading a laptop’s memory, SODIMMs are often the go-to choice for many users.

SODIMM stands for Small Outline Dual Inline Memory Module and is essentially a smaller version of the full-size DIMMs that are found in desktop PCs.

The advantage of SODIMMs is their much smaller physical size which allows them to fit inside the restricted form factor of laptop computers.

In addition, they typically consume less power than their larger desktop counterparts so they can help with battery life as well.

All in all, there are plenty of advantages to using SODIMM modules for upgrading a laptop’s memory, and generally speaking, you should have no problem finding one that meets your needs.

DIMM vs SODIMM: Explaining the Difference

Choosing between DIMM and SODIMM memory can be a daunting task for computer users.

But understanding the difference between the two forms of RAM will make the decision easier, allowing you to confidently choose the best option for your system’s needs.

DIMM and SODIMM offer distinct advantages depending on their size and shape, so it pays to learn about these memory formats before making a buying decision.

Size Matters:

First, it’s important to note that DIMMs are larger than SODIMMs, which means that they occupy more space inside a desktop case or laptop chassis.

This greater size also comes with an increased number of pins—DIMMs typically use 168-pins compared to the 72-pin design found on SODIMMs.

The extra pins enable DIMM modules to transfer data faster than their smaller counterparts, which makes them ideal for high-performance desktops and gaming PCs.

On the other hand, because SODIMMs are smaller in size, they can fit into smaller enclosures such as thin laptops or all-in-one computers.

Speed & Performance:

Another key difference between DIMM and SODIMM memory modules is their speed rating.

Generally speaking, a DDR4 DIMM module will run faster than a DDR4 SO-DIMM module due to its larger size and greater pin count.

In most cases, desktop systems require higher speed ratings than laptops in order to support intensive tasks such as media editing or gaming.

As a result, you can usually find higher speed ratings on desktop RAM versus laptop RAM whereas 8GB DDR4 3200MHz SO-DIMMs are fairly common, 16GB DDR4 3600MHz DIMMs are not difficult to come by either.


Compatibility is another point worth mentioning when considering the differences between these two memory types.

Because each type of module uses a different form factor with different pin counts, they aren’t interchangeable you won’t be able to install a DIMM into a laptop or vice versa.

It’s also important to note that some motherboards only accept one type of module over another for example, some boards may be limited to just 4 slots for SO-DIMMS while others may have 8 slots available for larger DIMMS.

When shopping for new RAM modules it’s always best practice to check your system specs first before purchasing anything.

Final Verdict

You can upgrade your system memory quickly and easily with SoDIMMs, making them ideal for laptop users who want to boost their performance.

While SoDIMMs may cost more than regular DIMMs, the extra expense is worth it for the added convenience and portability they offer.

If you’re looking to improve your laptop’s performance, switch to SoDIMM memory modules today.
