Hi Guys -

I'm really stumped on my problem/issue and hope someone can give me some help in rectifying it.

Last night I was flying FSX (yes Ludo, FSX :biglaugh: ). After flying a default plane for around 30 minutes FSX froze and stated that I had "run out of memory" ???????

My system specs are as follows -

Q6600 Core Duo Quad (2.4 gig)
4 GIG Dominator Dual Core DDR2
8800GTS with 640MB dedicated DDR3
4 standard issue Antec 900 case fans
1 additonal 120 mm side fan
3 memory stick top fans
1 standard CPU fan
1 M/B heatsink top fan (I don't think cooling is an issue)


FSX specs -

Everything other than traffic etc set to High
FPS fluctuating from 8 fps to 45 fps
ONLY default FSX run - NO add ons at all

My initial thought was a pagefile problem, but that seems to be refreshing itself as it should - at least it appears to be doing that.

Have run ATI Tools testing my 8800 and that too seems okay.

As said, I am baffled as to why I am getting this error message and why FSX freezes and crashes. Any suggestions will be very much appreciated, or to hear from anyone who has also had this same or similar problem.

Hey Tony,

Check your virtual memory setting and see if it is at max. I had a
problem some time ago with a Photoshop program that kept giving me out of memory errors. Turns out I had gone from 1GB RAM to 2GB RAM but XP did not readjust the virtual memory (same as you use 4GB of RAM). Manually bumping it up to max resolved the issue.

I hope this resolves your problem my friend, and I will continue to look for a solution for you ;) .

Hey Tony, did you check if you have the latest XP 64bit driver for your video card? It also might and I repeat might be that you have a faulty stick of Ram . . . . . when your sim crashes does it show a blue screen very briefly? If you do see this blue screen briefly, try taking out 2GB of RAM and see what happens . . . . it happened to me too as one stick was kaput and it screwed up the other 7GB of RAM.

PS: Do you have the latest FSUIPC version installed? if not get it here http://www.schiratti.com/dowson.html .

I dont know if this will help, but maybe try locking your frame rate at a set value that your computer can easily stay at. A fluctuating framerate I believe can take up virtual memory and cause stutter in game play. I have mine locked at 20fps and I get smooth flight almost all the time. Hope that helps, if not I have some other crazy ideas :)

Hi Guys -

Thanks for the advice.

Ludo -

Have changed my virtual memory sttings to the maximum recommended, from 2000 and something to 6000 and something and am downloading (or trying to) download the new FSUIPC now.

Have also run tests on my memory and vid card and both seem to be okay, but will keep an eye on them anyway.

FalconFlyer -

Have reduced my FSP rate back to 40 (as that is what I seem to get when all is well) and thanks - any advice is appreciated no matter how crazy :thumbsup:

Maybe this will shed some light on your problem Tony . . . http://support.microsoft.com/kb/892610

Hi Ludo -

Sorry for not replying sooner but as you know I have made additonal changes to my system with the addition of the 9800GX2 and a further 4 GIG of Dominator.

This seems to have resolved the "out of memory" issues I was having, not to mention re formating my computer :)

Only othr issue I now have, and I doubt this is resolveable, ny FPS on FS9 have dropped considerably, sometimes as low as only 4FPS.

I have been told that this may be due to an incompatibility (that word again) between FS9 and my new hardware and the only way to fix it would be to download a "compatibility patch", which I doubt exsists for the 9800GX2 and FS9 :(

I'll see what I can find on this incompatibility with the 9800GX2 and FS9. It could be that you 9800GX2 is a little too advanced for FS9, but I'll check just to make sure.
