Can 32 bit Windows use more than 2 gigs of RAM?

Suppose one wanted to dedicate 2 gigs to processes and another gig or two to a ram
disk for libraries, header files, and compiler/linker. Can this be done with 32 bit
Windows?
I'm wondering if putting a lot of RAM into an ideal build machine could help speed up
builds.

Defragmenting the swap-file can make improvements.
Seem Windows is using it, no matter how much RAM yo've installed.

With PAE, yes.

Hi!
Be careful with PAE option because it only works if motherboard is a
good one and drivers are well done; sometimes on defective drivers (more
of you could think) you will get a lot of BSODs.

According to that page Win2k Pro and Win XP Pro will both use 4 gigs. So one doesn't
have to go to a server OS version unless one wants to go above 4 gigs. So one could
have a 2 gig ram disk if one wanted. Or one could allocate 1 gig to a ram disk and
have 3 gigs split across several apps.
