Running out of memory

[Bufo]

Hi,

 

DCS is crashing after playing some time because my system runs out of memory, of which I have 16GB. I do not use SWAP at all.

 

There are no other programs running in the background. Is this a normal behavior? I would think that this amount of memory should be enough.

Hi Bufo

 

Advice,

 

Enable your swap file, set it to system managed.

Just because you have 16 gigs of ram doesn't mean your OS can use it all. For instance Windows 7 home only allows the use of 8 gigs of ram regardless of how much you have installed. I had similar problems until I upgraded to Windows 10 and was able to take advantage of all of my memory.

Yes, but I have Win 10 x64 installed which can use it all.

 

I do not want to use SWAP. Is it not possible that there is a memory leak? I so wish Rust and other memory safe PLs to advance instead of C/C++ :(

why don't you want to use your swap file?

 

If you want to fly crash free enable your swap file, that is the solution.

Maybe he uses an SSD, this is at least why I deactivated my swapfile

Yes, this is the reason.

I use SSD's never had a problem with them and I use a swap file

Running without a Swap File in Windows is actually pretty dangerous.

 

That being said, Swap File Usage on 16+GB Systems is low, and would not effect SSD Life.

 

Even with Just Windows Sitting on the Desktop, you're using Memory,

Processes and Tasks will use more memory as well when running DCS.

 

So Even if DCS Uses 12 GB, Other Processes will use more as well, Eventually some items would need to be placed in the Swap File to make room.

Guys swap file management is from 1998 and Windows NT. Keeping up with the advances in technology isn't easy for a working person. Just know that SSDs are a matter of fast storage access and Ram is fast program response. One does this the other does that.

 

The oil is high tech. in my car. It still requires gasoline.

 

My grandfather thinks you guys are right, he was reading over my shoulder. he also still uses a VCR.

Not correct. Just because they may look the same in the Windows management, does not mean they are the same. Microsoft has tried to keep some of the interface for settings similar in the interest of the consumer but the paging file system for FAT32 is nothing like the paging system for NTFS.

 

Also, it's not recommended to disable the swap file for any systems including for SSD drives. Swap file is based on how many applications you have loaded into RAM. Here are two articles explaining this. One is directly from Microsoft and the other is from Tweakhound on performance research.

Bottom line is that it's always better to reduce running applications or add or increase the physical memory. If you can't add more physical memory then it's time to think about upgrading.

You do realize that is what I was saying.........Right? You may want to re-read my post.

I do not use SWAP at all.

Hi.

 

Read this: SSD, PageFile and Low RAM.

 

I turned off pagefile at the first day I purchased the SSD. I don't remember this issue in those days, but I got same error lately, especially in Virtual Aerobatics Server; Long flight, lots of units etc.

 

I was worrying about SSD's lifetime, but enabling pagefile has solved the problem. No problem so far...

That is incorrect. The windows home basic 64 was limited to 8gb home premium was limited to 16gb which most people had home premium not the basic.

This may make a little clearer.

My swap files usage when DCS runs is about 8-11GB.

 

I have 4 drives, 2 x SSD and 2 x HDD, I let win10 decide what to use and what not.

 

You also cannot overwrite that setting totally, if windows decides to create a swapfile, it will do so.

 

The net is full of articles regarding this....and you will find both worlds being described as the sole solution. Pick your destiny :)

Best Solution, Get a Small 64 GB SSD and Leave Swap File on that. :) w/ nothing else. Call it a Swap Drive..

 

Die Hard Photoshop People call it the scratch drive :-)
