On your Supported Architectures page (https://puppylinux-woof-ce.github.io/arch.html)

In the x86_64 section you have the following

"x86_64 is just x86 with 64 bit addressing capability. This gives the operating system access to 64 GB of RAM natively."

The first part is partly correct as the addressing capability did increase to 64 bits. However there were quite a few other important improvements other just how much ram could be used.

The big mistake though is that the _64 stands for 2^64 bytes not 64GB.

Initially the increase was to 2^40 bytes which allowed 1TiB of physical memory. The current level is 2^48 bytes which ramps it up to 256 Tib and because of technical overhead the max is only going to be 2^52 bytes rather than the full 2^64 which ends up giving us 4 PiB.
