If you are always running out of RAM with 12 GiB, you need to look into the applications you are running. I have a notebook with 4 GiB RAM and 8 GiB swap and it is usable with Fedora (KDE Spin), Plasma, and some applications. Are you running only standard desktop applications or some memory-intensive simulations or something? > Due to the number and size of applications I'm running, I normally have to > close Thunderbird when I want to run Chrome.

I am running Trojitá (IMAP mail) and Falkon (web browser) right now, plus Konversation (IRC) and KNode (NNTP, in which I am writing this message right now), and KSensors reports 2096 MiB of RAM and 0 MiB of swap used. So what is using so much RAM? Are Thunderbird and Chrome so memory-hungry or is it the other applications you are running?

I just stick to twice the RAM, because taking 16 GiB away from a 3 TB RAID1 to make room for a 32 GiB RAID0 swap is not going to make any practical difference.
