    Question What Computer Makeup is Recommended with Revit

    I'm not talking about beauty products, I was wondering what everyone else is using / finding works best for performance when running a Revit project?

    I am suffering heavy loss of time and have lost information daily due to crashes while I've been putting my architectural thesis project together on Revit. My building project file is 34 Mb and my Site file is 8 Mb in size. I literally had to cease making changes to my toposurface due to time loss and crashes.

    I have a Pentium 4, 3.06 Ghz, 512 Mb RAM, 120 Mb HDD (40 Gb Free) and NVIDIA GeForce FX 5200 128 Mb video card. Pretty basic stuff these days.

    What is everyone else using - and what seesm to work best? Is there a new standard for Revit users?

    I should add, I kept getting this message....

    "The current session is using more memory than this computer can efficiently support. This could be slowing down some operations"....

    ... adding more RAM to the computer was identified as a potential solution, but is that enough and how much is recommended?

    Do you regularly close all hidden windows? I found that doing this helps with the ram error messages.....

    But that does look a big project!

    We have no problems with dual processor P4 - 1GB Ram and we just run on the onboard Intel graphics cards, apparantely Revit doesnt make much use of fancy graphics cards (or dual processors for that matter).....

    The dual processor helps if we have more than one Revit session open (I think) which as you will know you need to do with linked files when editing them, and also when rendering.

    We dont use a lot (well any really!) of Site data in Revit, maybe it uses a lot of computer power to do a lot of it?

    I wouldn't say that's too large a project. Average maybe!?
    From what I could see at this end, I would say you're lacking in RAM.
    The recommended use to be 1Gig. I think it's up to 2 Gigs now!?
    Revit is a great tool but it takes a lot of time processing. This is my biggest gripe!

    Better get 2 GB of RAM for that project if you want to finish it out. If it is close, 1 GB should be enough. I have 512 MB in my home computer and it barely will run Revit, just doing small projects. I don't think Revit is any more a memory hog than any other program. Take a multi file project in other programs (ADT, DC, SP, MS, etc.) and open them all at once and try and make it work similar to revit, including rendering - You will crash your system just the same if you don't have enough RAM. Rendering really eats up the RAM, and all rendering programs will do that.

    The issue is probably memory. We have done up to 120 MB projects with up to 8 Revit users. We use 3.4 MHz Pentium 4s with 2GB memory and 128MB graphic cards. Though saves to central can be slow these machines get the job done. I assume you are using Revit 8 which we've found much more stable than Revit 7. I also assume you have not created a central file. We found that Revit performs worst when you have a central file and local file located on the same computer.

    Yeah, you want to run at least one gig of RAM.

    By the way, running two copies of Revit to edit linked files may theoretically confuse the thing, and is not recommended. That's why one instance will not open both files simultaneously.

    Works fine, honestly! never caused me any crashes yet. But I can see it may not be recommended by Revit Developers!!... but it will work, sometimes saves an awful lot of time opening and closing files..

    Sounds like a minimum of 1 GB RAM is the recommendation.

    I would like to know what the Revit developers feel about the dual-processors, do they make a difference running a session of Revit?

    This will help me on future computer purchases / updgrades.

    Thx.

    From what's been said here before, Revit itself does not benefit from dual processors. However, Accurender can take advantage of dual processors.
