Win XP Application RAM Usage

[jimarthur]

I'm a user who has a (very) basic understanding of XP.  Our computers are 32 bit machines with 4Gb of RAM, (some have dual processors, some are dual core, 2 are dual quad core)  Some of our large CAD models seem to crash frequently (Pro/Engineer software).  The crashes seem to be tied to the amount of RAM available.  We have XP Pro, SP2.

1.  Will increasing the amount of RAM on these machines solve the problem? 

2.  Can any 32 bit software use more then 2Gb of RAM

3.  Of the 4Gb available, 2Gb is for OS only and is the remaining 2Gb available to all software processes?

4.  Can we change the boot.ini to the /3Gb to solve the problem, or will this cause other problems?

4.  Will 64 bit machines with 4Gb have the same problem?  64 bit with 8Gb?

Thanks,

Jim

i think 32 bit windows can only deal with 2 gigs unless you mess with the bios but im not sure

installing Winxp X64 edition should solve your problem;)

The RAM tuning may not be setup properly...
