How to check how much RAM you have in Windows 10 and 11

In Windows 11, finding out how much RAM you need is a simple task requiring just a few easy steps.

Note: The screenshots below are for Windows 11, and though Windows 10 looks different, the steps are identical.

Step 1: Open the Settings app. The easiest way is to right-click on the Windows icon and select Settings.

Checking how much RAM your PC has in Chrome OS is a little less straightforward, but still easy enough.

Step 3: The amount of RAM in your PC will be listed next to MemTotal, in kilobytes (kB). Divide by 1,048,576 to get the amount in gigabytes (GB) that's not being used by the Chrome OS system, then round up to get the amount of installed RAM. For example, the Chromebook used in this how-to shows 16248736kB. When divided by 1,048,567, the result is 15.59GB. Round that up to 16GB, which is the amount I already know is installed in the laptop.

Frequently asked questions how much RAM you have

How do I tell how much RAM I have?

That depends on your device and operating system. Check the sections above if you're on a Windows PC or laptop, Apple Mac or MacBook, or a Chromebook. For a phone or tablet, you'll want to look at your device settings, or on the manufacturer's website.

How to check maximum RAM capacity?

Maximum RAM capacity can relate to a physical maximum, such as only having a certain number of slots to install RAM. In other cases it can relate to the design of the product -- Apple's latest generation MacBooks, for example, have unified memory on the CPU, so the maximum you can get is the RAM it came with.

Look on the manufacturer's website or in the manual to find out how much RAM you device can take. When you need more, use our RAM buying guide to help you make the right choice.

Is 16GB of RAM enough?

This depends on the device and what you want to do with it. For a standard PC used for web browsing, emails, and social media, 16GB is plenty, and for a low-end laptop or tablet, it would be complete overkill. However, if you want to play demanding games, do some video editing, or 3D design work, you really want 32GB of RAM or more. But remember, it isn't all about the capacity of the memory. RAM speed does matter, too.

You have one year to safely use Windows 10 before you’ll need to pay

Microsoft will be allowing consumers to join its Extended Security Updates (ESU) program for the first time next year, and it announced the program pricing today in a blog post. The official end-of-service date for Windows 10 is October 14, 2025, but by paying $30 to join the ESU program, you can receive an extra year of security updates. This will allow you to continue safely using Windows 10 until around October 2026, a full two years from now.

By the time support for Windows 10 ends, it will be almost exactly four years since Windows 11 launched and a decade since Windows 10 launched. It takes a lot of work to keep an operating system secure and running smoothly, which is why a company like Microsoft can't just endlessly support every version of Windows it's ever shipped. It would end up costing a lot more money than it made -- and that's not how businesses function.

The M4 Mac launch is incoming, but not how you might expect

The past few months have been full of speculation, anticipation, and pretty wild rumors concerning the upcoming M4 Macs -- and now the predicted release date of November 1 is just a week or so away. Despite the lack of an event announcement, Bloomberg's Mark Gurman still believes the launch is "imminent," with an announcement reportedly coming on October 30.

According to him, Apple Stores are running very low on iMac, Mac mini, MacBook Pro, Magic Keyboard, Magic Mouse, and Magic Trackpad units -- and this usually happens when updates are about to be released.

Windows 11 24H2 may crash your PC if you have a certain SSD
The blue screen of death in Windows.

Microsoft's Windows 11 2024 Update, more commonly referred to as 24H2, is here, but it's not without issues. Reports from disgruntled users have flooded various forums, talking about constant blue screens of death (BSOD) that have appeared since they updated to the latest version of Windows. Although Microsoft has yet to officially acknowledge the problem, the users seem to have pinpointed the cause of it, and even found a workaround.

So far, it looks like these crashes are fairly limited in scope, as they seem to happen if you have one of a few Western Digital SSD models. Other SSD vendors appear unaffected so far. As reported on the WD Community Forums, users are getting BSODs with the error "critical process has died" ever since they updated to the 24H2 update.
