Ehm 32bit cant do more then 2.5 gb or something like that 32 windows limit is 3.5 gigs, you can put more in, but it will be seen as 3.5 gig. In linux you can have up to 64gig in 32bit by changing highmem4 to highmem64 in the kernel config file. For windows32 you can try editing your boot ini to include /PAE.
