Creo on 32-bit with PAE memory blast to access 4g

[bpenza]

Hoping someone has some experience with this.

I used PTC/Creo on a home computer (windows 7 32-bit 3g ram). (I also have it at school with 4g, 64-bit, no problems)

Realizing that Creo really requires a min of 4g to really use. (Especially on the assembly stuff, constraining in a video blanked world is no fun)

I decided to upgrade to 4g. Then I realize that windows 7 32-bit doesn't really do 4g. So I think about upgrading to 64-bit windows (which this desktop will accomodate). But then I see an option on-line to use the PAE memory add-on. I figure why not give it a try. I'd have to reformat everything for 64-bit install, so I've got nothing to lose.

So I install the PAE software fix, and I can see the 4g , I'm still in 32-bit and all windows system values show me that I'm okay for 4g.

However, in PTC/Creo , I still getting video phase outs when I try to assembly parts. Especially on constraining sections. I can work around it by rolling the mouse wheel and guessing a lot, but it sure would be nice if PTC/Creo could work in this PAE cluged world.

Anyone had experience with this? It seems that the PAE memory enhancer doesn't really do what it claims, at least not in Creo. Or is there a PTC/Creo setting that might resolve this?

I am sure that the PAE is installed properly and the computer is working fine in all other ways.

Thanks for any helpful advice.

Brett,

Use the following steps for 32-bit Windows 7:

1. Open a command prompt window as Administrator
2. Enter the following command (requires administrative privileges - see 1.):

bcdedit /set IncreaseUserVa 3072

Thanks Martin,

It does seem to help. But I'm still getting some "washouts" in video when I do Assemblies with pretty simple parts. Not a show stopper, but it is sometimes hard to find the constraint feature when the video turns to white with line geometry popping up here and there.

Thanks for the help.

Brett,

in case of graphics problems, it is recommended to add (temporarily) the following option at the end of config.pro file and test usual actions in ProE/Creo.

graphics win32_gdi

If problems disappear, then the problem is related to graphic card itself or to graphic drivers (you can try to install different version of drivers).
