Solved Virtual Memory running low then crash

January 16, 2013 at 12:37:35
Specs: windows 7, 2.67 Xenon / 4gb
I've got a computer running windows 7, 32bit with 4gb ram. when running Auto cad 2013 I'm getting a Virtual memory too low.. and a few minutes later the system will reboot.
i have gone in and changed the virtual memory settings to 6gb, thinking that would help.. it seemed to for a few days but then it started popping back up so i changed it to 20gb.. knowing for sure that would fix it.. it didn't ... still coming up with that virtual memory error.. any ideas.???

All I can think of is that your hard drive free space is getting too low, so the virtual memory you allocate isn't actually available.

✔ Best Answer
As it only happens on Auto CAD try this:

Note there is only one space in the command, which is after bcdedit
Note also the disable in case you need it.

Always pop back and let us know the outcome - thanks

I agree with phil22 that you might be low on hard drive space but I would suggest turning the virtual memory back to the default settings (let windows manage this) as Windows 7 is good at managing it's own paging file/virtual memory.

I think your problem may be that you are running on a 32-bit OS. This limits the amount of memory that can be utilised. I would say that you need to run on a 64-bit machine, preferably with 8-16GB of RAM. AutoCAD is very resource intensive when the models get complicated. A decent graphics card wouldn't hurt either.

If not #1 or 2 above then probably #4 BUT also test your memory for errors with Memtest via a bootable CD you make with the ISO image you download and test your hard drive with your hard drive mfg's utility from their website, preferably the DOS version via a bootable CD as well (run the long test).

You have to be a little bit crazy to keep you from going insane.

Solved this problem with the bcedit to switch on 3gb ram access. the virtual memory error has gone completely away. no crashes in at least 2-3 weeks. Mind you, this was a daily thing before, sometimes 2-3 times a day. Thanks All.
