How to check how much RAM you have

Knowing how much random-access memory, or RAM, that your PC has is important for a number of reasons. First, you want to be sure you have enough RAM for your needs. Second, you might want to install a particular application that has a specific recommendation for the amount of RAM it needs to run smoothly.

The great thing is that it's extremely easy to find out how much RAM your PC has without cracking open the case. Here's how.

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 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.

How to configure a Mac Studio that’s right for you

Apple's Mac Studio is an elegantly designed desktop PC that fits into tight spaces. It's also one of the quietest desktops you'll find, making it an unobtrusive choice, while also providing surprisingly fast performance.

But while the Mac Studio offers decent connectivity, it's also a sealed enclosure with zero expandability. What you order is what you'll have forever, so choosing carefully when configuring your Mac Studio is vital. This guide will help you make the right decisions.

Have the M3 MacBook Pros made the Mac Studio irrelevant?

It might seem strange to compare a desktop PC to a laptop. After all, one is intended for stationary work, and the other is meant to carry around. They have different internals, different connectivity, and usually different performance.

But Apple's Mac Studio and MacBook Pro (especially the 16-inch variant) are a different story. For Mac users, both represent the fastest Apple computers you can buy. Depending on how you use a desktop PC, either machine can suffice. So, which one is right for you?

A revolution in laptop RAM is upon us
Dell's CAMM laptop RAM module.

It's time to bid a slow farewell to the SO-DIMM memory standard we've grown used to seeing in some of the best laptops. A new standard just got approved by JEDEC, the organization that defines specifications for various types of memory -- and it's going to be faster, offer higher capacity, and take up far less space. What's the catch? Unsurprisingly, it's likely going to cost a pretty penny.

According to JEDEC's official announcement, the new memory module is called CAMM2, and it's not exactly as new as it might seem. It was first introduced by Dell in the Precision 7670 laptop, and it was initially simply referred to as "CAMM." It brought a bunch of improvements over SO-DIMM, but being a proprietary memory module, it locked users out of RAM upgrades and replacements -- after all, Dell was the only company to produce this type of memory. With CAMM2 now standardized, we're going to see this RAM become more widespread over time.
