I have an i5 12gb RAM Windows 7 Ultimate 64bit machine and I recently had to kill several processes because it ran out of 'Free Memory'...however there was still 7.5gb in 'Standby' Memory.

I didn't have that much open (Outlook, VS2010, SQL Server) but not really running any of them. Iwas typing an email and it just stopped.

I killed VS and SQL Server and then it slowly recovered...my question is if I have nearly 8gb of Standby memory not being used why does it run out of memory and die and can I somehow adjust the amount of memory

thanks

one cause could be wrongly configured pagefile –  kaykay Apr 7 '11 at 4:05

1 possibility, Poorly coded programs may not release memory when it is needed by other processes, or the program has a memory leak.

Open a run box and type in resmon , then go to the memory tab, see what is using all the memory.

You can also install and run RAMMap it gives a better display than resmon and has much more information to help solve the problem.

Some insight on how to use RAMMap

Also check your pagefile size.

Ahhhh I'd forgotten this little gem. Comes in handy! –  enderland Oct 30 '13 at 21:00

There are some prudent things you can try to see if it will help: http://windows.microsoft.com/en-us/windows7/Ways-to-improve-your-computers-performance

But you're not running that much, so I think that Moab may be onto something where there may be some poorly coded programs.

In my opinion, it is probably the absence of a page file. I have been having the same problem since I have disabled the page file on my workstation. I have 32GB of RAM, and after two or three days without a reboot, my standby memory usage is up to 29 GB, and my system starts grinding to a halt. It seems Windows x64 does not always gracefully release the standby memory.
