32bit Inventor on 64bit machine

[Anonymous]

I am running IV2008 on a 64 bit processor with 64 bit Windows XP with 6gig of RAM. My system is limiting Inventor to 3.2gig of the RAM and leaving 2.75gig for the operating system and other applications. My question is simple. Is there a way to force the system to allocate more of the RAM to Inventor and less to the other apps? I know we did this with the 3gig switch on a 32bit system, but I know this is not an option with the 64bit machine. But is there any thing that can be done to accomplish this?

Thanks in advance for any insight given in this matter.

What makes you say or where are you seeing that
Inventor is only getting 3.2GB?  A 32-bit application running on a 64-bit
platform should be able to address a maximum of 4GB.

The meter at the bottom of the Inventor window says that I am using 3214mb of RAM with 212mb free.

Thom,

The 64 OS will grant a full 4 GB to any 32 bit process. The reported 3.2 Gb used with 212 Mb free by Inventor is perhaps indicating that cached memory is making up for the renaming 600 Mb. This will free up when needed.

The OS will manage what processes are granted the physical RAM. With 6 GB on your system, you should see very good performance with minimal swapping, as the OS and Inventor both have plenty of space with which to work.

Thanks for the reply Pete.
Here is the situation. My assembly is just under 8600 parts, lots of piping, lots of content center parts. The meter is almost completely red. Only a very tiny sliver of black at the end. And the performance is slowed way down.
The good news is that I have it broken into much smaller sub-assemblies, so I can work on them without maxing out the system. I just need the full power when I try to open the entire assembly.
However, I still see that I am not getting the full 4 gig of RAM to be allocated to Inventor. If I was getting all of it the meter should not be completely red (or that is how I perceive it).

Your system still requires the O/S to be memory
resident and is using the remainder (0.8GB). You simply require more
memory.

Then the OS is using 2.8 gig of the 6 gig that is installed. Windows should not need 2.8 gig of RAM should it?

Unless you have a number of applications/utilities
running in the background.
