PAE can cause all kinds of instability issues in a client system, and should be avoided for Windows. I believe the issues stem from driver incompatibilities. Given the widespread support for Windows 7 x64, and the zero cost to switch from x86....there's no reason not to go that route if you need that much memory.
I'm not trying to take sides, but you did bring it up. I think I can speak for OldMX and many others when I say...we cringe when we see it even mentioned in these threads. There was a specific user, on here and on [H]ardForums who posted under the same name on both forums....and would always extoll the virtues of PAE, telling everyone to do it, rather than run an x64 OS. Countless times, the OP would follow, and then a week later be asking how to perform a clean install due to instability issues. Perhaps his comments weren't meant for you personally...just as a gut reaction to even seeing those three letters posted again.
I'm not taking sides either, but while I know of this PAE switch and have actually worked with 32 bit servers with larger amounts of RAM, I didn't even bother to utter it's existence to the OP as it would have simply caused confusion. I think without question, going the 64bit route is a far better option.
I sympathize.
Maybe I should let "impossible" stand, when the literal truth is "a really bad idea", or "of no practical value". Particularly when anyone of sufficient knowledge to use the PAE hack with open eyes probably wouldn't be asking after it here. (I'm not at that knowledge level, myself. I wouldn't touch it with a 10 foot Registry hack.)
