mskin Posted November 30, 2007 Share Posted November 30, 2007 This is a general question, that in this case directly applies to REVIT, but i think it could be answered by anyone who knows a bit about computers. Why does autodesk suggest as a required system one with both 4G of RAM and Windows XP Professional when I thought that combination was impossible. I thought xp pro limited you to 3G of RAM?

AJLynn Posted November 30, 2007 Share Posted November 30, 2007 Not true. It won't use the full 4 because of a limitation in the address space of the system RAM overlapping the video RAM but it will use more than 3. The 3gb limitation is the address space that can be given to user apps, the system keeps the other 1gb, but the address space includes both real and virtual RAM so having the full 4gb in there can improve performance if you've got an app doing crazy shit. Like Revit can. Link to comment Share on other sites More sharing options...
BrianKitts Posted December 1, 2007 Share Posted December 1, 2007 if you've got an app doing crazy shit. Like Revit can. yeah.... now if they could only get revit to take advantage of multiple processors...... Link to comment Share on other sites More sharing options...

BrianKitts Posted December 1, 2007 Share Posted December 1, 2007 my former office bought up all the new systems for revit with 4 gigs of memory, great video cards and dual quads..... good news was we turned it into a great render farm at night..... bad news, it only runs on one of eight cores, so it's SLOOOOOW, comparatively speaking to what it could be.... I scoured REVIT forums looking for any sign of autodesk getting REVIT to utlize multiple threading..... no such luck, so I resorting to a short burst of profanity any time I had to go into revit to pull out a model for max, and left it at that. http://forums.augi.com/showthread.php?t=64769&highlight=multithreading Most threads suggest a strong xeon processor for revit. And you will get some use out of having multiple cores such that there's extra processing power for your OS and normal operations in addition to anything that you do multitasking.....but like I said, Revit while only spike you on one of em.

AJLynn Posted December 1, 2007 Share Posted December 1, 2007 I think Revit recommends a Core 2 Duo (2.4 GHz I think) because there's no single core CPU that's as fast as one of the Core2's cores. Link to comment Share on other sites More sharing options...
