I will bookmark this page for reference. 8)
Many are asking why aren't they seeing a 4gb RAM after they installed 4GB on their Windows XP Pro 32bit. This explains why. Quote 64-bit versions of Windows Vista Business, Enterprise, and Ultimate: 128GB Can't imagine what I can do with this size of memory! :DTitle: Re: Maximum Addressable Memory (RAM) of Different Operating Systems Post by: ftracena on July 02, 2009, 01:38:55 PM yup , but with currently available memory in market is only 4gb ram module, i think maybe a couple of more years, you can slot a 32gb ddr ram to [txtspk] mobo, (x4 pa so that makes it 128gb) think how powerful a 64bit pc's will become...wew
