32bit operating systems cannot address more than 4GB of memory. It is
simple math. Two to the 32nd power is 4GB. That's all the unique addresses you get mathematically. To use your full 8GB of memory you need to run a 64bit version of Windows XP or Vista, or a 32bit version of Windows Server 2003 Enterprise Edition or higher. See the memory tables he http://msdn.microsoft.com/en-us/library/aa366778.aspx "veryunhappy" wrote in message ... hi there i have just installed 2x2gb memory cards to go with my other 2x2gb cards making a total of 8gb of ram as that is what my mother board can take i have checked bios start up menu and the ram is in as it is saying i have 8196mb of ram but when i go onto base index score to check for hardware the extra ram is not showing as the new hardware is not being detected ?????why is this does any body know how i get it to show os is vista home prem 32 bit many thanks -- veryunhappy |

It is not because 32bit systems cannot address more, as you also mention Windows 2003 can do it, Microsoft just made a choice to not support more than 4G in Vista. |

A 32 bit OS can not CONCURRENTLY address more the 4GB as Colin pointed out.

No it can't. What you are describing is simply remapping.

Read the table I linked. No, MS did not make a decision not to support more
than 4GB in Vista. No 32bit Windows clients support more than 4GB, XP included. Windows Server 2003 Standard Edition and Windows Home Server don't either. Higher 32bit editions of Windows 2003 and 2008 do so through PAE. "dennis" wrote in message ... Colin Barnhorst wrote: 32bit operating systems cannot address more than 4GB of memory.

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" |

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 ...

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.
