Your computer’s memory, or RAM, is a short-term storage solution for the central processor (CPU). It helps your CPU run apps and programs faster.
This volatile memory erases data when turned off, so it’s important to save work to permanent storage like a hard disk or SSD. RAM is available in several forms, including CMOS-based SRAM, SDRAM and DDR-based SDRAM.
What is RAM?
The amount of RAM your computer has and uses can have a huge impact on how fast it works. Whether you’re a PC gamer, a photo editor, or a business professional, having enough RAM helps your system work at its best.
The short-term memory of your computer, RAM stores the data that your CPU (central processing unit) needs to access quickly. Unlike long-term storage like your hard drive or solid-state drive, the data in RAM is erased as soon as you shut down your computer.
The speed of your RAM is crucial because it allows the CPU to read data faster than from a hard drive or SSD. This speeds up multitasking and performance, so you can juggle more programs at once without your computer slowing down. Most computers come with a certain amount of RAM, but upgrading to more can help you get the most out of your machine.
Why do I need RAM?
Your computer needs RAM because it provides high-speed, short-term memory for the central processing unit (CPU). The more RAM a computer has, the quicker and smoother its performance. RAM allows your computer to open larger files, use demanding applications like video editing software, and juggle multiple programs at once without slowing down.
Computers and laptops also have long-term storage on a hard disk or solid-state drive, but RAM is much faster for accessing the data that your apps need right now. If a program needs more RAM than it has available, it must read the information from the longer-term storage, which takes more time and slows down your CPU.
To make this transfer process as quick and seamless as possible, Windows features a feature called SuperFetch that analyzes your usage patterns and pre-loads programs into RAM for you. However, it’s also possible to clear wasteful junk manually or with specialized optimization software.
How much RAM do I need?
If your computer struggles with day-to-day tasks, has trouble opening large files, or runs out of memory while gaming, you may need more RAM. The more RAM you have, the faster your CPU can work and the better your PC will perform.
Generally, 16GB of RAM is recommended for most users. This gives enough headroom for standard applications and can handle modern games, though demanding titles may require more.
You can upgrade RAM by purchasing additional modules and installing them in your motherboard. However, you cannot download RAM, as it must be installed physically. Websites or applications that claim to offer downloadable RAM are usually scams.
It’s important to check the capacity and speed of RAM before buying. High-speed DDR4 RAM can make a big difference in frame rates and performance when gaming. Check your motherboard’s specifications to find out what form factor and speed of RAM is compatible. It’s also worth considering adding VRAM to your GPU, which can improve graphics performance.
How do I know if I need more RAM?
RAM acts as a high-speed temporary workspace for your computer, allowing it to quickly store and access data that the CPU needs in real time. If your laptop is struggling to open programs or runs slow when performing memory-intensive tasks, it may be time for an upgrade.
Adding more RAM can improve your experience dramatically, though it is important to consider other factors like CPU speed and storage type as well. You can monitor your computer’s RAM usage by opening Task Manager and navigating to the Performance tab. If you notice that the percentage of RAM used is consistently above 60 percent, it’s likely time to upgrade.
It is also a good idea to keep in mind that RAM upgrades are much less expensive than replacing an entire laptop. Check your laptop’s specifications or manual to see if it allows for RAM upgrades, and if so, what type and speed are compatible. You can also look up the compatibility of specific RAM modules online.
