To effectively use anything over 3GB (excepting, of course, rare PAE-aware applications), yes, you must use a 64-bit version of Windows. 4GB is a hard 32-bit OS limit--regardless of the OS. Windows just chooses to reserve between 1 and 2GB (dependent upon the /3GB switch) exclusively for the kernel.
