Amount of Memory

[Bill Daggett]

What's so dumb?

The part: "Some 32-bit OSes can be specially configured to make use
of up to 64GB of physical RAM,"

No desktop 32-bit OS can address more than 4GB of RAM.

No? Don't send an apology, I'd rather a litre of Coca Cola:

Quoting directly from that wiki article:

"This, **theoretically**, increases maximum physical memory size from
4 GB to 64 GB. The 32-bit size of the virtual address is not changed,
so regular application software continues to use instructions with
32-bit addresses and (in a flat memory model) is limited to 4
gigabytes of virtual address space."

I said "physical memory" i.e. RAM - so you still owe me that Coke!

Never heard of PAE? 32bit Desktop Linux can and does.
