Why is my system freezing if I have 32GB of RAM?

You should definitely check your RAM usage. Use a command like 'free -h' in the terminal or look for a GUI tool in your desktop environment. Freezing can be caused by various issues — inadequate CPU power for multitasking, driver problems, or even a slow hard drive could all contribute. 32GB of RAM is typically enough unless you're running very demanding applications.

Having some swap is usually a good idea regardless of how much RAM you have. Just a little, like 4-5GB, can help the system manage memory better. But if you're still having issues, it might not just be about RAM or swap space; faulty RAM or hardware compatibility might be the culprit.

Make sure you're checking your actual RAM usage first. If it looks like you're really close to maxing out, then that's a sign. Also, consider using zRAM if it’s not already enabled. Given the freezing, it might also be related to driver issues or graphics settings, so keeping drivers up to date and trying fallback configurations can help.

It's definitely possible to run into 'out-of-memory' issues even with 32GB of RAM. Linux is quite aggressive with memory usage for things like cache, buffers, and more. When you don't have swap space, the system doesn't have a backup plan when memory spikes occur, which can lead to freezes. Nobara, being a gaming-focused distro, might put extra pressure on your system. You might consider enabling some swap or zRAM to help manage memory spikes better.
