No, it can't. Windows 32-bit can access 4 GB of physical memory and no more, period. Installing 8 GB of memory on a 32-bit windows machine is folly as only half of that allotment can be addressed. The /PAE switch engages a 'smoke and mirrors' approach to SIMULATE more memory, not provide actual physical addresses.

If you really want to access more than 4 GB of memory you need to ditch the 32-bit version of Windows and install the 64-bit release.
