Windows 8: 8TB of memory available for games?

I discovered something interesting. Unless I’m mistaken, large address aware 32-bit games may be able access up to 8TB of memory.  I don’t know what tricks the OS is using to do this (a 32-bit process should only be able to see 4GB) but a cursory look indicates when running on 64-bit version of Windows 8, a 32-bit process that is using large address aware is “seeing” 8TB.

Take that with a grain of salt since my guys are skeptical about whether you can actually use any of that.

8TB!? Modern technology is just screwing with me these days. 

I'm still stuck with 2GB of DDR2 until I can change 70% of the system at the end of the year.

How are you going to address 8TB of memory when your registers are only 32-bit (EIP, etc). Even in the AMD 64-bit extended architecture, your 32-bit processes are limited to EXX registers and aren't aware of the 64-bit ones (EIP is inside of RIP). 

I think I know why your games are what they are.

No. 32 bit games will not be doing this. If you want that kind of memory you're really going to have just bite the bullet and make it 64 bit.

8TB storage or ram?

This would be only for LAA enabled games, of which there are still very few.
