OS Type: 32bit max RAM / 64bit max RAM

Windows Vista Ultimate: 4 GB / 128 GB
Windows Vista Enterprise: 4 GB / 128 GB
Windows Vista Business: 4 GB / 128 GB
Windows Vista Home Premium: 4 GB / 16 GB
Windows Vista Home Basic: 4 GB / 8 GB
Windows Vista Starter: 1 GB / N/A

With 32 bit usually less than 4GB will be usable. Usually around 3.2 GB or less.
