The Dreaded OOM Message - This time with a Win 7 64 Bit Machine

[joneseric]

This is my first post on the forum - over the years I have learnt an awful lot from the informed advice given. Here goes.

 

My System is Win 7 SP1 64 Bit machine running on an Intel I7 4790K@4000Ghz, MB ASUS Z87-K, 8GB Ram.

FSX is at SP2. I use ASN and a virtual airline ACARS.

I use Process Explorer to monitor VAS.

I the virus scanner OFF when using FSX.

 

My Scenery Config is managed to switch OFF unwanted areas.

 

The issue I have is that the OOM occurs when Private Bytes and Working set exceed 3 GB, I get an audio warning followed by a message stating FSX has run out of memory.

 

Aircraft in use = Aerosoft, A319

Scenery - UK Photoreal Gen X V3, UK Airfeilds, UK2000 Heathrow.

 

Situation - OOM occurs in cloud or low visibility on approach at night.

 

I thought a Win 7 64 bit OS allowed up to 4 GB of VAS, my system is failing OOM when VAS usage goes just over 3 GB.

 

Please can I ask if any one has had a similar issue and been able to fix it.

1. Take a deep breath.

 

2. Make a backup copy of your FSX.CFG. Put it somewhere, so you can find it again.

 

3. Delete the FSX.CFG.

 

4. Start FSX. Do you get the OOM error now?

 

5. If you don't get the OOM error, then go to Kosta's tweaking guide, posted as a sticky in this forum, and start re-tweaking. One step at a time.

It could be that your Windows 7 does not have PAE enabled, this would limit the VAS space to about 3.2 Gig.

 

1. get the ID of your Windows system with the command line tool "bcdedit"

2. Force PAE "bcdedit /set [{ID}] pae ForceEnable"

3. If DEP is active, you can't activate PAE. To disable DEP use "bcdedit /set [{ID}] nx AlwaysOff"

I'll post what I have for FSX Cfg. You pick & choose what you want to use.

And there should NOT be 2 (Display Device .......) sections (ie: 2 different video cards).

Thank you all for such clear advice. I will try tonight when I get home. Just for info these are 2 video devices in my config as I have 2 video cards in my system driving 2 monitors, one is 4K 42'' the second is a standard vga for other programmes.

All - Thanks.

 

EVM - Thanks for the advice, however my machine is 64 bit capable with a 64 bit OS with PAE enabled by default. I am off to have a go.

 

Napamule2 - Thanks, my cfg is going to be deleted and then I will try and force an OOM, then include some of your suggestions, just for info I have 2 video devices in my cfg because I have 2 video cards in the computer running 2 monitors.

Why do you need two video cards for two monitors? A ton of cards, including the one I am using, can run as many as six monitors. I currently always "fly" with at least three monitors and from time to add a 4th.

 

I'm not saying that is your OOM issue. But that sure seems like another complication you don't need to fool with.

[joneseric]

My main monitor is a 4K 42" curved screen running at max resolution, my second monitor runs at a lower resolution. It all works fine and has done for 2 years. Thanks for the advice.

Chaps - An update to me problem, for now fixed. Just to recap, my issue was FSX was not using the 4 GB of vas it should have been able to use as my system is a 64 bit CPU based machine with a Win 7 64 Bit OS.

 

Firstly a complete rebuild of my FSX cfg file using advice found in this forum. Secondly, enabling DEP for FSX, my system was set as DEP = OS only. This was the mod that made a difference. I am using FSUIPC to monitor VAS and also Process Explorer. Thirdly a cull of processes using Black Vipers advice.

 

I am now back to FSX sliders to almost max and air traffic set to 50%.

 

So far so good, I stress tested with sliders to max and silly LoD settings and I still had 0.25 GB left in VAS although by this time the CPU was struggling.

 

Thanks to everyone for helping
