- Pae for extended memory support is disabled because of the performance hit and the fact that all drivers must support Pae or the system will not work.
"32-bit Vista, like 32-bit Windows XP SP2 and later, doesn't really support PAE. You can turn PAE on, but you won't then actually be able to address any more memory. The only reason to turn PAE on is if you want to activate the no-execute (NX) or execute-disable (XD) features of modern CPUs, which require larger-than-32-bit memory addresses, to accommodate the extra bit that activates those modes. That's all PAE does on these operating systems.
The reason why PAE in XP and 32-bit Vista doesn't expand the memory map is that for a computer to work with PAE, all of its kernel-mode drivers need to be PAE-aware. If any of them aren't, the computer will hang.
Microsoft gave up on ever having enough PAE-aware drivers for mainstream WinXP computers, which is why, as of SP2 back in 2004, they abandoned the larger address space and changed the PAE mode for the mainstream 32-bit versions of Windows. Now it only gives you the same 4Gb maximum memory as non-PAE mode. Non-PAE-aware drivers then work fine." http://www.dansdata.com/io090.htm http://www.dansdata.com/askdan00015.htm
