LUZR4LIFE Posted August 25, 2008 Share Posted August 25, 2008 I have a friend with a Acer 5520 It came with Vista 64bit and he upgraded to XP 64bit, he no only shows 3g of the 4g he has. What could be the issue? I know nothing about 64bit, so any help is appreciated. THANK YOU Quote Link to comment Share on other sites More sharing options...
NIM Posted August 25, 2008 Share Posted August 25, 2008 Hmm, x64 XP should allocate whole 4 gigs, but if not you can change the way of RAM allocation by editing the boot.ini file.At the end of the line you should add /PAE switch. Quote Link to comment Share on other sites More sharing options...
