Random access memory (RAM) is arguably one of the most influential components in the overall speed of a laptop. As the name suggests, it is responsible for storing temporary data in an easily accessible location, allowing for faster speeds when running multiple programs simultaneously.
Each time you run a program on your laptop (or desktop), the operating system (OS) stores some of the data on the RAM until the program ends or the laptop is shut down or restarted. Since this is a temporary method of data storage, it is often referred to as virtual memory. When your laptop's memory is full, the OS will attempt to store the data on the hard drive. While this prevents system crashes, it is not as efficient or fast as storing the data on RAM.
Generally speaking, the more RAM (measured in megabytes or gigabytes) you have installed in your laptop, the better its ability to multi-task. This is particularly beneficial for users who frequently run multiple programs and processes at the same time. While processor clock speed and hard drive write speed play a role in a laptop's overall performance, RAM is the key component that enables effective multi-tasking.
RAM Speed and Performance
RAM speed is another critical factor affecting its effectiveness in a laptop. RAM speed is measured in two ways:
- Operating Frequency: Defined as the data transfer rate.
- Bandwidth: The speed at which the memory transfers data.
For example, DDR4 RAM such as PC4-25600 operates at an operating frequency of 3200MHz and provides a bandwidth of 25.6GB/s.
Laptop Memory Configurator
When choosing RAM for your laptop, it is recommended that you first check the owner's manual. A laptop that uses 262-pin DDR5 SO-DIMM RAM, for instance, is not compatible with 260-pin DDR4 SO-DIMM sticks. This is where our Laptop Memory Configurator can help.
Use our bespoke configurator to find the exact laptop memory for your machine. Simply locate your manufacturer (e.g., Dell, Acer, Sony, etc.), and you will find your model listed along with all compatible memory upgrades.
The configurator will also help you determine how many RAM slots (the areas in which the memory sticks are installed) are available on your laptop. Desktops typically contain four slots, whereas most laptops contain two. If both slots are occupied, you will need to replace the current laptop memory sticks with new ones.
Most modern operating systems, including Windows 10 and Windows 11, are designed to take full advantage of available RAM. However, if you are using a 32-bit version of Windows, your system will be limited to a maximum of 4GB RAM, regardless of how much is physically installed.
To check which version of Windows you are running:
- Open Settings.
- Go to System > About.
- Under Device specifications, look for System type, where it will indicate either "64-bit Operating System" or "32-bit Operating System".
If you are running a 32-bit system and need to utilise more than 4GB of RAM, you will need to upgrade to a
64-bit version of Windows.
Hopefully, this has given you a better understanding of RAM memory and the role it plays in laptops.
