Its called google!!
You can't, unless you upgrade to 64-bit Vista. This is due to the 32-bit memory limitations.
there are still ways to address up to 4gigs, a lot of it is how BIOS limits it, and of course Windows doesn't take over properly. Other 32bit OSes can see and address 4gigs of memory.
I understand and have read Microsofts explanation, soooooo it must be purely software limited if you can purchase/upgrade to Vista 64 bit and immediately be able to use more than 3.1 GIG.
Right/Wrong
I believe the keyword is "others". To make space for it all, you need to address more than 4GB. That is beyond Vista.
But as said, and stated in those Microsoft KBs, Vista cannot go above 4GB no matter how hard you try.
A note on that PAE monster: if you google "Data Execution Prevention", you'll find out why Vista supports PAE. But even if it is actually technically possible to address >4G, the memory manager doesn't allow it. So it is a no go.
Yeah I agree, but Microsoft says lots of things that aren't true and I think we can also both agree on that as well.
They go to great lengths to document how anything above 4G is just being ignored, though. And I have yet to see anyone being able to do it.
It is also worth noticing that most people already have pae enabled, because of that dep-thing.
