Out of Memory???????

 ??? I recently bought a new hard drive for my pc and I am running on Windows7 Ultimate. i reinstalled all of my FSDT sceneries (have em all) and my pc keeps crashing when I am on approach or trying to lift off from any of these sceneries. I run the default flight and I have no problems! What setting should I be decreasing in order to stop the crashes? I have already tried scenery detail and complexity decreases!

Hnla:
As for any other thread about OOM, which has been discussed too many times, it's NEVER, EVER a problem of a single item, the problem is the sum of EVERYTHING you install, which can't surpass 4GB in total, read the explanation here, there's nothing really much to add:

http://www.fsdreamteam.com/forum/index.php?topic=9017.msg72396#msg72396

It's about JFK but, since the problem is not any single scenery, it applies to any other configuration out there.

Before the PMDG 777 was released, the most memory-hungry airplane out there was the PMDG 737 NGX so, most users flying with that airplane struggled to have all their installed add-ons to fit into the absolute, not extendable, 4GB memory limit.

The 777 seems to take about 200MB MORE than then 737 NGX.

This means, if you are flying that one, and your configuration was carefully optimized to fly everywhere with the 737 NGX, if you go to the SAME airport with the 777, you WILL get an OOM if you were already close to the limit, and you'll be mislead thinking "it's the scenery", when of course it isn't, since the scenery surely hasn't changed.

As discussed in too many other thread, since those 4GB are not negotiable, not unless we'll have a sim written in 64 bit code, regardless how high your system specs are, there's no way you can use more than 4GB for FSX.

This means, you must either:

- Lower your settings.

- Use DX10.

- Use 2048 or 1024 texture size.

- Don't use so many add-ons at the same time.

Any of these is valid so, you have options.

Frank Lindberg:
Amen... Hnla is absolute correct  :)

Bruce Hamilton:
You can also invest in a higher end graphics card, and take some of the load off your CPU.  You'll still have that four gigabyte limitation of FSX being a 32 bit program, but you'll crash less often because your GPU is doing more of the work.

SgtMav316:
i am in total agreeance with you on the aircraft demanding too much memory. I had my simulation running at 1360x768  ::), I noticed when I dropped it to 1280x768 the OOMs stopped. Right now I was test flying a Flythere EMB-135XR from Heathrow to London City. Taking off no OOM warning (there is a distinct warning chime that I hear just before the sim crashes). As I approach London City airport I start hearing the OOM chime going off (Usually 5 of those in rapid sessions=Sim Crash). Couldnt understand why it was occuring.

I read your responses and decided to look at the res setting on my pc and for some reason it went back up to 1360x768 where I was having the OOM message. I returned it back to 1280x768 again will see if it continues! When I dropped the resolution to 1280x768 on my last session I did notice faster frame rates and no OOM warnings. This kind of bites if you know what I mean. Why is it that developers are pushing the envelope with all of these new products.

Yes FSX can display the airports in high detail and aircrafts in high detail, but when they go beyond the 4gb limit that just makes users frustrated to keep getting the OOM messages and warnings when all we want to do is enjoy what we paid for! Most developers release airport sceneries with too much unnecessary surrounding houses and bldgs around the airport that eat up a lot of memory! So to resolve it they develop patches that allow you to edit out the surrounding products.

I wish I had the PMDG 777, I fly the Capt Sim 777 and it too has the same issue when used at certain airports with OOM killing the sim! Luckily 1280x768 still looks good on my pc and when displayed across my projector so I am not complaining about it! But as we move forward we still get products that exceed the FSX limitations soon we'll have to play FSX like the original FS Flight simulator looking at cubes! Wish developers would release the specs they are using on their PC when they develop their products that way we will know what we should be doing on our end to accommodate their product. Although one would think it should be the other way around.
