My specs are below, The E7400 is 64bit.

I'm running FS9, and I get Out of Memory Errors with FS9 alot. (fs9.exe runs over 1.2 gigs)

If I switch to 64 bit XP, do you think I will get those errors anymore? I hear that it runs the memory better, and all 4 Gigs.

Id though id ask around, since you guys FS9 and X specific people  ;D

You wouldn't get any advantage, even if you switch to 64 bit OS, if you are using an application that is not aware of the additional memory. FS9.EXE needs to be patched, in order to allow it to see more than 2GB, try to search in forum to see how its done.

TWA Pilot:
Maybe I can suggest something........Since i went to XPsp3, my FS9 glides like a hot knife through butter!

Just a suggestion....

Hey thanks, I was always doing the 3G switch and not this.

Basically, the only advantage of Vista 64, is that you don't need to do the 3GB switch on the OS, but you still have to patch FS9.EXE

However, there is some overhead running a 32 bit apps into a 64 bit OS, because every 32 bit API call the apps makes, needs to be translated at runtime by extending its parameters to 64 bit, with a process called "thunking" so, the same app might be more stable because of the extended memory available, but it will surely not run any faster, and possibly slower.
