XP Hogging My Memory

by renmahn / July 26, 2007 11:35 PM PDT

Hello, I just added another stick of RAM boosting my total to 4 GB. However my available memory is only 756MB! I had allocated 2 GB to Photoshop before this upgrade and it was working fine but now I am at 756 MB. How do I limit XP 's memory usage to about 1 GB?
Thanks, Ren

That's proper. In fact you want 0 bytes free!

Any VM based OS should eat every byte of RAM. Here's an article that explains it. ->

?Free RAM is wasted RAM?.

Nothing busted here. To limit XP's memory to 1GB there is a limit memory in MSCONFIG but that's just as bad as installing only 1GB!

Since you have over 2GB ram, a switch you need to know about

Thank You, /3GB Switch Fixed All
by renmahn / July 27, 2007 12:36 AM PDT

Thank you for your fast accurate reply. I modified the Boot.ini file with the /3GB switch and now Photoshop is allowing me 2.7 GB! I have limited this to 2 GB as this is all Photoshop can use.
Have a great weekend, Ren

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
