How to check how much RAM you have on Windows and Mac

Knowing how much memory, or RAM, that your PC has can help you better plan which applications to install and use. Here's how to find out.

You can only know if you have enough RAM, if you know how much RAM you need. Fortunately, checking is super quick and easy and then you can decide whether you want to upgrade your memory, or whether you have enough for what you need to do.

Here's how to check what RAM you have in your PC or laptop, and its size.

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.

Step 2: In the Settings app, select System then navigate to the bottom and select About.

Step 3: You'll find your installed RAM listed under Device Specifications.

MacOS also makes it easy to see how much RAM you have.

Step 1: Click the Apple menu and select About This Mac.

Step 2: The Overview tab should be selected by default. The amount of installed RAM will be displayed next to Memory.

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

Step 1: Open the Chrome browser and type "chrome://system" in the search bar. Select Enter.

Step 2: Scroll down to meminfo in the list. Select the Expand button.

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.

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.

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.

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.

The absolutely absurd idea of putting a touchscreen display on a mouse isn't exactly new. Turtle Beach already did it with its Command Series MC7, which features a 2.25-inch control screen. But apparently, even that wasn't ridiculous enough for Arctic Fox Technologies. Its new Super Mouse looks like someone took the chunky old Atari ST mouse, slapped a touchscreen and scroll wheel on it, and called it an upgrade.

The result is a rather unusual-looking mouse that is now on Kickstarter, starting at $199. And as ridiculous as it looks, some of its features are genuinely intriguing.

Apple is less than a day away from launching its highly anticipated OLED MacBook Pro with a touch-sensitive screen. But it appears that the upgrade is going to cost a pretty penny. According to a report by Bloomberg, Apple is reportedly eyeing a starting price of $2,899 for the 14-inch MacBook Pro, while the 16-inch version could start at $3,399 in the US.

"At $2,899, the 14-inch model would mark the highest starting price for a new MacBook Pro model, surpassing the $2,799 Apple charged for a 17-inch version introduced in 2006," says the report. The report claims that Apple is targeting a minimum price hike of $400 for its upcoming redesigned 14-inch and 16-inch MacBook Pro models.
