Make Windows XP (+Vista/Win7 32bit) access more RAM
Posted: Thu Sep 30, 2010 12:27 pm
If you have Windows XP Pro and 4 Gb of ram, it's currently limited to only 2Gb. Yes, you may have 4Gb installed, but the programs only access 2Gb, no matter how many XP "Sees" that you have.
Let's not worry for now why this is, but there's a solution.
You can open up 1Gb more of RAM, and it's fairly easy to do.
Here are step-by-step instructions for getting more of your RAM available for SketchUp and Twilight Render.
If you have done this, please report back to us, and let us know and how it goes.
It must be understood that enabling the /3GB switch is for XP Pro, and can cause system instability depending on the system used, available RAM and Hard disk space, etc. Proceed with caution, and always with a backup.
btw Vista 32bit will not use /3GB boot switch, only XP. It's safe to enable.
Vista and Win7 32bit users should use this.
64bit systems should already allow 4Gb of RAM for 32bit programs... unfortunately this appears to be the max. allowable RAM for 32bit programs, so even if you have 12Gb of RAM, SketchUp (& Twilight) can only use 3 due to 32bit limitations.
