I mean, I feel that the 4mb (I assume 4gb) of ram needs a 32 bit os claim is downright untrue.
I have a Thinkpad X301 that’s been upgraded to 4gb of ram, and I run Debian 12 stable, 64bit, and performance, even on a laptop from 2008, like mine, as long as I used pale moon for browsing, was stellar. I use xfce on that laptop.
