Windows 7 - Out of memory error

Hello guys... I'm new to this excellent place.
I think windows 7 is so cool and i haven't got any complaints. Going from xp home to this is Awesome.
However I play flight sim x and since i installed Windows 7 i keep getting out of memory errors after about 5 minutes into a flight. It ran great on xp with 2 gig of ram and an old 8800gts 640 meg card.
I'm still using the same graphics card but i upgraded my ram to 4 gig of corsair ddr3 ram.
I'm not really experienced with understanding graphics and ram issues... can anyone help

Hello Steve and welcome to the SevenForums!

have you tried running FlightSimX in compatibility mode?

(Right click its icon, select properties , Compatibility, Run this program as "Windows Vista")

or even xp if that is what it worked on b4

Thankyou for the suggestions guys, but unfortunately i dont have the compatibility tab... when i go into properties, I'm out of ideas.

I have the 32 bit windows 7 running, could it be i have virtual memory and page file issues?

Edit.. I have the compatibility tab with other games in the properties just not fsx???

try installing the 64bit version to utilize all 4gb of ram and try...

Ok i have the 64 bit downloaded and burned to disk.
I will install and give it a try. I dont know why i didnt install this one in the first place

Thankyou for your help

Old habits are hard to break

Also let windows manage the pagefile. The XP style adjustments are no longer necessary.

Have you tried clicking one the actual *.exe file in the FSX folder? Odd that it doesn't have a compatibility tab

Thanks, clicking on the exe file does bring up compatibilty tab. Gave it a try but still crashed to out of memory error. Gonna install 64bit tomorrow.

FSX works fine on Seven for me, it's not Seven I think.

I have found on a number of systems I have tested, that Windows 7 does not like some motherboards duel channeling/hyperthreading memory configuration.

I suggest configuring Ganged/Unganged or turn of hyperthreading. And if that doesn't work, try running 1 stick at a time.

I had 2x2gb (4gb) of RAM running 64bit Windows 7. It was crashing all over the place. I tested my ram, all ok. I tried running one stick and the crashing stopped

I now run 1 stick of 4gb instead of 2 sticks of 2gb. My system is just as fast and alot more stable. Also teted on all my other "problem" systems, and the BSOD simply stopped when I started running 1 stick of RAM instead of 2.
