Hi there,

I'm working on a small project (20MB file) that takes almost 6 GB of cache memory after a few hours working. The system starts when opening Revit with 3GB memory and after a while it uses 9GB memory. Windows gives a warning than that the system is running out of memory. I don't have may views open and no shadows on. A very small renovation project. I 'm saving the project file every 15 minutes.

Any one with an advice how to control or limitate the memory that Revit wants to use ?

My system is a Win  7 64 bit with 12 GB RAM. 3,0 GHZ PC.

Your problem is not Revit.  We work on 100+m projects on 32 bit, 4gig machines and don't have any problems.  Hopefully soon we will all be on 64 bit systems.  Your problem is more that likely your video card.  What is it?  Have you loaded the latest drivers for it?

I've got two ATI Radeon HD 5670 that are coupled via Crossfire. (1GB mem each) The latest drivers were AMD 12.8 but those ones gave lots of crashes on Firefox so I returned to version 12.6. I was told by AMD support that technicians are still working on newer drivers. They were known with the firefox problems. 

Revit even crashed on that small project of mine because of memory problems...

Well I succeeded in updating the AMD catalyst drivers now to version 12.8. But the memory problem is still there. 

It seems like the memory keeps occupied even after I close all the views and files Revit was working on. Even whithout any file open Revit takes 5GB of memory... You can see that in the pictures included taken while every program was shutdown and Revit was left open after a somef working but now whith all the files closed. When closing Revit the memory usage drops from 7 to 2 GB

Can it be that the video driver uses RAM memory ? I read something like that on the AMD forum but I thought it would be technical impossible.
