re: How big a RAM can be used for a 32-bit OS Friday, July 23, 2010 at 8:52 am Windows XP Annoyances Discussion Forum Posted by Ronobir Ray (56 messages posted) As the MSDN page shown by Martin the physical memory limit for 32-bit XP is given as 4GB whereas in Memory and Address space limit it says that it can address only 2 GB and with IMAGE_FILE_LARGE_ADDRESS_AWARE and 4GT it can address 3GB. If anyone can elaborate on the difference cos in the Memory and Address space limit section it says in a 64-bit environment the limit is 4GB.
