Re: 4GB in windows xp pro

Yes. The same amount of memory shows regardless of the mode.

PAE is normally not useful on XP with only 4GB of ram. It is not designed to resolve the issue you are addressing. Here is an article on PAE:
http://msdn2.microsoft.com/en-us/library/ms791485.aspx
As you can see PAE addresses specific needs involving NUMA and DEP and is automatically enabled or disabled as required. The needs concern certain driver bugs. Even with PAE switched in you won't see 4GB but would see slightly different numbers from what you do now. See:
http://support.microsoft.com/?kbid&ID=888137

I doubt that you can twiddle enough in the BIOS to recover any significant ram for user programs. Remember, there are two of you using the computer; you and the computer.

Thank you both for the quick reply. It sounds as if i should leave it
settings alone and see what that does for my machine. I have yet another
(probably stupid) question, My motherboard supports dual channel DDR, If all
four sticks are matched then even if all the memory doesn't show, will
whatever does show run in dual channel mode?

Always Thanks

With proper hardware support, PAE is normally the way to go in 32-bit
OSes. But the PAE kernel in XP/SP2 doesn't allow more than 4GB to be
addressed in total, so when it comes to memory support, it doesn't
matter if you enable PAE or not.

Google DEP, if you want to know why there is a PAE kernel
