8GB of RAM necessary to fully utilize 64bit memory addressing

[Nothinman]

On my home machine I've got a 64-bit kernel and userland, on this machine I've got a 64-bit kernel and 32-bit userland. But that's completely irrelevant because even with a 32-bit Linux kernel I can enable PAE and use all of my memory just like I should be able to do.

so? in windows 64bit you get a 64bit kernel + 32bit AND 64bit userland. Again, I don't see what the problem here.

Its a hypothetical "well IF I Was using windows at ALL, and decided to choose to use 32bit version for some obscure reason, and decided to put in 4+GB of ram... then I wouldn't not see the extra ram cause microsoft maliciously decided to prevent crashes caused by bad programs and drivers by preventing it"...

Well technically I have both too, I was just detaling what the primary installed was.

It's not hypothetical for most people because they already own a license for 32-bit Windows. There's nothing obscure about it.

Not bad programs, but yea pretty much. MS added an artificial limitation to their software which prevents people from using all of their hardware and you think it's a good thing?
