If you feel like your computer is slowing down or doesn’t quite have the pep it’s supposed to, check how much RAM you have. RAM is a significant part of your computer's everyday performance and having too little for what you want to do can cause bottlenecks. As a general rule, 4GB is too little, 8GB is fine for general internet browsing and streaming, and 16GB is the standard for gaming and video editing.

Once you have an idea of how much RAM you have and how much you need, you can decide whether to upgrade your computer or get a new one. Just be aware that some Apple laptops have the RAM soldered to the motherboard so upgrading might not be possible (for warranty purposes if nothing else).

Here's where to look on the best Windows computers or one of the best MacBooks or Macs

Final thoughts

Finding out how much RAM you have is as simple as it is important as it’s a potential bottleneck for all sorts of apps, not just games. Google Chrome, for instance, takes up plenty of resources for every tab you have open.

If you want to dive even deeper to see how your Windows computer is using your currently installed RAM, then open the Task Manager, go to the Performance tab, and press on Memory. You’ll see plenty of metrics that will either give you peace of mind or show you how much your currently installed RAM is throttling your performance. Plus, you can see the speed of the RAM here.

For an Apple computer, you’ll open the Activity Monitor app to see the same information. It should by default show memory usage, but if it doesn’t, just press on Memory at the top.
