Hi not sure this is the right forum but saw some topics with fatal error, and I do use win 7. In Dec I changed to a new computer and spend a nice amount to have a system which will allow me to use FSX without problems. Every time I ended up wiht the same problem that i am running out of RAM.... sometimes after 2 or 3 hours sometimes after a few minutes or just after starting the programm. attached some information abut my system and the response i do get. I spend hours reading through different forums, tried lot of things but always witht he same result.Now i hope that someone can hlep me to get FSX running smooth ...... i doubt it is my system ...For any support thanks in advanced...Werner

Werner - if I'm reading it right you have a 32 bit system so:You have a few options and yes it IS your system.Best - get a 64 bit OS and expand to 6G ram2nd best - get 6G RAM and use the 3/G switch - if not using SP2 you need to make FSX Large Address Aware3rd best - use the 3/G switch - if not using SP2 you need to make FSX Large Address Aware4th best - turn your sliders way down.If you are not aware of it, google the /3g switch and you should find plenty of info- also google FSX Large Address AwareYou also should look at overclocking that CPU.Good luck!

best to use w7 64 bit o/s and double your system memoryThe /3GB parameter, as far as I know, does not work with Vista or W7.

Negative - I've got FS9 (with several addons) on my sytem with W7 64 Pro and it works just fine. Visit the W7 OS pinned thread on this forum and it has all the tips and pointers you need to run FS9 smoothly.

thanks to all for your support have a nice weekendWerner
