Memory limit on XP pro sp2???
Subject: Memory limit on XP Pro??? 8/19/2005 5:37 AM PST
By: Eric Boltz In: microsoft.public.windowsxp.basics A client of mine recently purcahsed a graphics workstation. Huge rig, top of the line hardware. He got 4GB of ram in it, and all 4gb is seen during POST and BIOS checks. However, Windows XP will only show 3GB installed. I was able to get it to 'utilize' 3GB with the use of the /3gb switch in boot.ini, but still... is there any way to get XP pro to utilize all 4gb of ram, or did he blow a bunch of cash on extra hardware he'll not be able to use? Grillo I'm having the same problem and i changed the Boot.ini file and still showing less than 4gb...shows 2.75 gb???What should i do to fix that?The bios show 4gb too.My win is a xp sp2 professional.

A 32-bit system can only utilize up to 4GB of address space, so it can't use the full 4GB of memory for Windows, it needs address space for the things in your machine too, graphics cards etc, they all cut into the available address space. If you want to use the full 4GB of memory you'll need the x64 Edition of Windows and a x86-64 CPU. -- Paul Smith, Yeovil, UK. http://www.windowsresource.net/ *Remove 'nospam.' to reply by e-mail* |

Windows XP can and does utilize all of the ram. However, a user process only gets to use 2GB unless you invoke the 3GB switch. The remaining part of the virtual address space is used to map the system so that the user can get it to do things. Your client's system should run very fast with 4GB of ram. That extra GB is most definitely not wasted unless, of course, your client never read or writes to devices such as disks or monitors, never connects to a modem, never accesses the internet, etc. If you client never does any of those things, he does not need a computer.
