What Is RAM, and How Much Memory Do You Need?

Popular Posts

RAM (also known as memory) is an important component in your computer’s performance and speed. It doesn’t matter if you are looking to purchase a new computer or if you just want to improve your existing one, understanding RAM and what you need is crucial. This article will explain what RAM is and how to determine if your Mac or Windows computer has enough memory.

What is RAM?

RAM is a hardware component used to store temporary data on smartphones, computers and other devices. To boot up, operating systems like Windows and macOS must have sufficient memory.

What does RAM do?

RAM can be described as the short-term memory of your computer. RAM is temporary storage for program codes and data that your computer is currently using. Memory is used by your computer to launch programs, run actions, load features and many other functions.

Your hard drive and RAM both have gigabytes (GB) but they do different things. Your hard drive can be thought of as your computer’s long term memory. This is where you store all your programs and files when they are not being used. The data in your RAM will be deleted when you turn off your computer.

RAM on your computer is more powerful than any long-term storage drive. RAM stores the most commonly used data that your apps, programs and processes require on stand-by. Your computer’s memory is able to quickly retrieve information and pass it on to your central processing unit (CPU).

How much RAM do you need?

Basic programs such as Microsoft Word and surfing the internet will require at least 2GB of RAM. You will need at least 4GB RAM to run newer programs. If you use intensive programs or multitasking, 8-16GB may be required.

The general rule is that the more RAM you have the faster your programs run and the more you can run simultaneously. Your computer’s performance will depend on other hardware and software.

It is recommended to purchase memory sticks in pairs of identical specs to get the most performance from your computer. These memory slots are available in quad- and dual-channel configurations on most modern computers. This will give your memory more communication channels and improve data transfer speeds.

But, you can only use one type of memory card if the other is slower.

Are 2GB RAM enough?

You will be able to perform very basic tasks with 2GB RAM. This includes opening tabs on the internet, using Microsoft Word and Excel, and playing low-end games. You can only run one or two programs simultaneously before your device slows down.

Remember that you only need 2GB RAM to run 64-bit Windows 10. Your computer will feel slow and sluggish if it has less than 2GB of RAM. We used more RAM than that on a 64-bit Windows 10 laptop, even though there were no programs or devices connected.

Is 4GB RAM enough?

You have 4GB RAM which is enough to run several lightweight programs simultaneously. Open a few browser tabs and you can do basic image or video editing. You can also play low-spec games. You can stream music and videos online.

We used over 4GB RAM to open 10 tabs in Chrome while simultaneously running Microsoft Word (and Task Manager) on the same machine. These tasks may be possible with less memory if your hardware is more powerful or you enable certain settings.

These days, even low-budget laptops and computers come with at minimum 4GB RAM. Upgrading to 4GB of RAM will make your computer feel like a new machine. It is important to remember that older 32-bit computers cannot handle more than 4GB RAM.

Is 8GB RAM enough?

You will be able to run multiple programs simultaneously with 8GB RAM. You can open many browser tabs simultaneously, use photo or video editing software, stream content and play high-end games.

These days, many Windows 10 and macOS laptops or computers have 8GB of memory. 8GB should be sufficient to run most productivity applications. This is also the minimum recommended memory Adobe requires to run Creative Cloud applications like Photoshop.

Although 8GB RAM is sufficient for most people, it can be used up quickly if there are many tabs open in your web browser and multiple programs running at once. We used more than 8GB of RAM by opening 50 tabs in Chrome and simultaneously running Photoshop, PowerPoint Word, Word, and Spotify.

Newer games can also require up to 8GB RAM on their own. Cyberpunk 2077 , for example, requires at minimum 8 GB to run. If you have other programs running in background, you may experience a lot of lag while trying to run the game.

16GB RAM is enough?

You have 16GB RAM which allows you to run multiple programs without slowing down your computer. This memory is sufficient for gamers, video editors, streamers and anyone who uses AutoCAD or any other highly-demanding software.

We were unable to use 16GB of the memory on our laptop, for example, because the processor was slowing down everything too much. If you have 16GB RAM, then your processor is likely to be the cause of any bottlenecks.

32GB RAM is worth it?

You have 32GB of RAM which is enough to edit 4K video, model 3D environments or handle large files. If your computer is dual-booted, or you have multiple virtual machines installed, it’s worth it.

64GB RAM is too much?

You have 64GB of RAM which is enough for machine learning, feature film editing and 3D graphics design. Most power users will consider 32GB RAM excessive, particularly if you are only interested in high-end gaming and multitasking with a few programs.

You might be able to upgrade your memory now that you have an idea of how much RAM you require. There are other important factors to consider when purchasing memory sticks. These include speed and latency.

What is the difference between DDR3 and DDR4?

You’ll find RAM in a lot of shops. Most are DDR3 or DDR4 DDR5 sticks. They are both faster and more efficient than DDR3.

DDR stands for Double data rate, and the numbers 3-4 refer to the version of the memory chip. The megahertz (MHz) measure RAM speed, also known as frequency or clock speed. This is the speed at which your RAM can access its storage space every second.

DDR3 RAM has a speed limit of 2133MHz. DDR4 RAM is capable of speeds up to 4266 MT/s (million transfers per seconds). DDR3 RAM can only hold 16GB per stick of data, while DDR4 can store up to 256GB.

DDR3 RAM sticks and DDR4 RAM sticks come in different sizes. DDR3 RAM sticks won’t fit in a DDR4 slot. Before you upgrade your RAM, find out which RAM slots your computer has. It is also important to remember that laptops use different types of RAM than desktop computers.

What about DDR5?

DDR5 is the newest version of PC memory and was only made commercially available in 2021. The new RAM standard is faster than DDR4, has a higher capacity and is less energy-intensive. The standard is still in development and does not yet work with all computers.

Is RAM speed important?

If your CPU is slow, RAM speed will not matter. If your other components are capable of handling it, however, you may notice a slight increase in performance due to faster RAM. You can also increase your performance by upgrading your GPU or CPU speeds.

In their technical specifications, some CPUs indicate a recommended RAM speed. This recommended speed can boost performance but only marginally. While you may not notice a faster frame rate when gaming with faster RAM you may see a higher 0.1% or 1% frame rate. You should also ensure that your motherboard can handle higher RAM speeds. If it doesn’t, your RAM speed may stop working, which will mean that it won’t matter how fast you are.

What is a good CAS latency for RAM?

Latency refers to the time it takes for a RAM stick to access data. Lower latency is preferred for RAM sticks that have identical speeds and chip versions. DDR3 has lower latency than DDR4, but DDR4 offers much faster speeds and better performance.

Here’s how you can find out how much RAM your computer has once you know what RAM speed, capacity, and latency mean.
