force XP to use pagefile first

August 2, 2011 at 00:27:11
Specs: Windows XP

Hi,
I have a problem with Autodesk Inventor eating all my RAM and not touching the pagefile at all during a project export leading the software to a crash. So, I was wondering if there's a way to force the system, or better, a specific applicaition to use pagefile first, so I can avoid the crash in certain moments (well knowing that the performances would be decreasing).
Searching on the web only leads to force the physical memory to be used first by tweaking the registry, but not viceversa.
The exporting process takes up to 6gb on a 64bit OS workstation and I need to do it on a laptop equipped with 4gb and a 32bit OS.

Thank you

Right-click "My Computer", then "Properties".
Choose the "Advanced" tab. Under "Performance" click "Settings".
In Visual Effects, click on Custom & untick everything, except these 2 > Smooth edges of screen fonts & Use visual styles on windows and buttons ( Default has everything ticked, except > Smooth edges of screen fonts )
Click Apply & then OK.
Advanced
Processor scheduling & Memory usage, select Programs for both.
Virtual Memory > Change
I use > System managed size

More options.

Many thanks for your reply,
but I already knew and applied all theese stuffs, what I wanted to know is if it's possible to tell the os, maybe with a registry key or something, to alway use the pagefile first because right now it doesn't seems so (with all the settings you suggested). I need it due to a heavy workload on the ram caused by Inventor, wich seems to use not the pagefile at all.

Thanks

If the application is using lots of RAM it is because Windows has determined that is the best use of RAM at that time. It is Windows that controls memory allocation,not the application. If something else comes along that needs the RAM more than the application then Windows will take appropriate action and start swooping things out to virtual memory as and when required. Or that is the way it should happen.

If the application is crashing because of excessive use of RAM then that is an application problem and you need to contact the vendors of the application. There is no Windows tweak that will compensate for programming errors.

The link below shows system requirements.

http://usa.autodesk.com/autodesk-in...

You want Windows to use system RAM before using the page file, which will be much slower.

The requirements do state that you need at least twice the virtual memory as system RAM. IMO that isn't much slack space on the hard drive. for best results your drive should have at least 20% free space and the partition should not be fragmented.

I didn't read all the requirements but there could be other issues when running on a laptop besides the amount of RAM and the virtual memory.

If more pagefile is needed then it will be allocated. I doubt if the reason for your crash is what you believe. More likely there is a bug with the program or it has not installed correctly.

Always pop back and let us know the outcome - thanks
