DISQUS

Jan · 2 years ago

Hello SW collegue.
I have got a question about this memory trick. My VAR here in the Netherlands gave my basically the same line to type except an extra /SOS has to be added behind userva=2900.
Since I actually notice a speed slow down when using this 3GB switch I wonder if this is caused by /SOS. Does anyone have n idea here?
My Xeon system with XP and 4Gb memory runs better without the 3GB switch now and I wonder why.

Before you give the 5 instructions to modify the boot.ini, I would put in bold letters "Do not attempt this unless you have SP2." Some people might not read the article by Eaton and Tiffany and attempt this process with XP SP1.

Also, you make it sound like it will work for any program, but that's not true. In order for a program to make use of the /3GB switch, it has to have been compiled with the /largeaddressaware (LAA) switch. However, there is a way to modify an .exe file, giving it LAA support, which means it will recognize the /3GB switch. The ugly way is to use a command line editor from Microsoft called editbin.

A much nicer way is to use a program called LaaTiDo. It's a Windows program. You use the program to search for the .exe file to modify. Then you click "check" to see if it has LAA support. If it doesn't, click "Backup" to make a backup of the file. Then click "Enable" to Enable LAA support. You can then click "check" to confirm that the modified file has LAA support.

I can't test it because I only have 1GB on my system.

Read the author's web page which contains the link to the file:

Hey Peter, thanks for the clarification and the link to the .exe modifier. I almost assume that everyone is at SP2 at this point but very important to point out and check. To check if you are running SP, go to Windows Explorer, click help in the menu and select About Windows. It should show up after the version number. Also, ALWAYS make sure you backup the .exe before modifying!

Thanks Peter!

This might very well help a very good friend of mine with her problem using large graphics files. Thanks Josh.
