UM no.............. my xp pro dual dual core opti system is running 6 gigs, i see alot of people claim that it is 3 gigs, but i have passed that many times, no it might be my xp pro, it is not a standard issue.
Um no...if you're going to lie make sure you know what you're talking about
Windows XP supports 4GB of system memory which is accountable for both physical RAM and your virtual RAM pagefile dedicated from your hard drive. The only Windows operating systems that will support more will be server grade (eg Windows 2003) and must have the /PAE switch enabled...an option not availible in Windows XP regardless of version or service pack
Furthermore, even if I'm wrong and there is a way to crack the operating system to address more memory...your processor then becomes the bottleneck. 32 bit registers are only capable of addressing 2^32 (4 294 967 296) or 4GB of memory and there is NO way around this unless you increase your registers bitrate in which case you'd have to be running Windows x64 or another 64 bit operating system which you've already explicitly stated you haven't
Futhermore, you'd need 64 bit instruction sets to even take advantage of the extra memory otherwise it's just sitting there doing nothing and isn't even being recognized by the program in question, and since 64 bit applications are limited the added memory really serves little to no advantage...and since you basically just listed numerous applications above that are NOT 64 bit compliant you basically dug your own grave
Sure you HAVE 6GB maybe...but it's not doing you a whole lot of good
