Anyone run this switch to access 3GB of ram in XP 32-bit?

Wondering if it adds instability or conflicts?
Thanks,

I've tried it before, but the biggest thing to remember that even though you turn it on, your application still needs to have the /largeaddressaware flag turned on or it won't be able to use the extra ram. (Limited to the same 2GB for 32 bit apps. I believe 64 bit apps can use up to 3GB.) I don't recall any issues when I had it set. Either way the ultimate fix is just use Vista 64 bit and it will allow up to 4GB of ram by default.

I understand all this and have known about it for years...but something I have not been able to get a straight answer on is a system with 3GB of ram w/XP 32.
My question is: if having 3GB and NOT using the switch or the fllag, does the 3GB work as 2GB for the prorgam/game and the remaining 1GB for the O/S? Seeing as XP only needs a few hundred MB at startup, I imagine a 3GB system would have at least a full 2GB for running programs, is this correct?

Not sure what you mean by this, are you saying that every program or *.exe file should now contain the flag "/largeaddressaware "?
