Windows xp and 4gb of ram

[Bollwerk]

Well, for my rigs at work, we are modeling some rather large assemblies that take up a lot of space/memory/cpu. We are using XP32 and I have currently 4 gigs on mine. At first, I ran it without the switch till I found it. While using my modeling program, it would crash/run out of memory ...etc etc, so after I added the switch, it stopped doing that and it runs a hell of a lot smother. So, if you wish to use 32, by all means, use the switch, you will gain performance out of it, but then again, it's only going to read 3.5, so, go with 64 vista or xp to get more ram if that is the end result you are going after.

There's a /3GB switch you can put in boot.ini, but what that does is allow a single process to address 3GB of memory instead of the default 2GB limit.

Therefore, the /3GB switch will not help people who multibox on the same machine.
