Where I worked back in 1995, we had DEC Alpha workstations running Windows NT processing what were then huge images. We had DEC workstations running 4 GB of RAM. I think some Alpha systems had 8 GB installed even back then. The Alpha was 64 bit native but Windows NT was still 32 bit so I think you needed VMS if you wanted more than 4 GB. A 64 bit version of Windows 2000 for Alpha was created but never released ( this was the first 64 bit Windows ). It was not totally impossible to see beyond 4 GB of RAM.
