64bit Win7 + ACAD 2010 - only using 2gb of 6gb Printed From: CAD Forum Category: EN Forum Name: AutoCAD Forum Description: Discussion about AutoCAD and AutoCAD LT, viewers, DWG and DWF formats, Design Review, AutoCAD 360, add-ons URL: https://www.cadforum.cz/forum_en/forum_posts.asp?TID=3083 Printed Date: 22.Apr.2026 at 14:49 Topic: 64bit Win7 + ACAD 2010 - only using 2gb of 6gb Posted By: ColArco Subject: 64bit Win7 + ACAD 2010 - only using 2gb of 6gb Date Posted: 25.Jan.2010 at 13:56 have machines running 64bit Win7 + 64bit ACAD  -However they are only using 2gb of the available 6gb Opening large files (around 9-10gb) results in 'Autocad -not responding'   - however -after long delay -will open- but be so slow as to be unusable. (eg - 10 or 20 min to open -or respond to any change of tab change etc). Window's resource manager clearly shows only 2gb being used  -also shown as ' around 30% total memory use'. I'ts also clear that drawings grind to a halt -as they approach 'using up' this 2gb limit. (other software will quite happily take advantage of the avaiable memory above this 'limit') Its as though ACAD is in 32 bit mode - i.e. not aware of the memory above the 2gb level. Anyone any ideas ? Not getting far with our 'paid for' autodesk support so far ! ------------- Col Replies: Posted By: smithlayman Date Posted: 28.Jan.2010 at 08:07 This may be a silly question but do you have a really good video card installed in this machine as well? You need alot of RAM and a good graphics card to get a good result, just a thought, I am no expert but I lock up my CAD all the time and it is because I do not have a machine that handles it well enough on larger files. Usually the RAM runs out on me. But I also know I needed and good VGA card....just a thought, again, no expert... ------------- Melody Layman
