It is not mathematically possible to address more than 4GB with a 32bit
addressing scheme. PAE was implemented only for Server editions, beginning with Server 2000 Advanced Server, because those editions of Windows had a critical need for the additional address space at a time when 64bit Server editions were not yet ready. It was not necessary to make any decision about the 32bit clients. MS subsequently met the need to provide a workstation OS that could address more than 4GB with XP Pro x64 for both IA64 and x86_x64 systems. "dennis" wrote in message ...

Windows Server 2003 Standard Edition and Windows Home Server don't either. Higher 32bit editions of Windows 2003 and 2008 do so through PAE. I know that only a few of their editions supports more than 4GB, and that a decision they made. It is not because it is a "32-bit OS" |

The point with PAE is to extend the number of bits the OS can use to address physical memory. So in PAE mode the OS can address more than 4GB. |

Quit before Colin flattens you like a stomped bug. You're not gonna win this one. |

Only if the OS has support for it, which Windows clients do not.

A 32-bit system can only address 4GB, by the time other hardware is included
it'll be even less. You'd need to move to a 64-bit system, such as Windows Vista x64.

The trouble is in the real world PAE, and other extension "hacks" would often crash systems because hardware manufacturers drivers weren't written to support it. As such it was phased out in favour of just using 64-bit. If PAE could be enabled on a consumer OS, the system wouldn't work properly due to lack of driver support. -- Paul Smith, Yeovil, UK.

Which clearly states what I have been trying to tell you:
"Although support for PAE memory is typically associated with support for more than 4 GB of RAM, PAE can be enabled on Windows XP SP2, Windows Server 2003, and later 32-bit versions of Windows to support hardware-enforced Data Execution Prevention (DEP)." It is not enabled in XP SP2 and later Windows clients for the purpose of supporting more than 4GB of ram. As the tables I have been linking for you clearly state, Windows clients like XP cannot under any circumstances support more than 4GB of memory. As the article at https://www.microsoft.com/whdc/syste...AE/PAEdrv.mspx says, "* Total physical address space is limited to 4 GB on these versions of Windows." "dennis" wrote in message ...

Congrats to Yeovil Town in dodging the relegation bullet in League 1 this
year. Do you go and see them play? "Paul Smith" wrote in message ... A 32-bit system can only address 4GB, by the time other hardware is included it'll be even less.
