Hi,FSX is freezing usually on a longer flights than 1h. I run overclocked i7 920 @3.8GHz. I have the system tweaked exactly to Nick N's settings. On a shorter flights I don't see a problem but on a longer flights it happens every time. I'm begining to believe this could be caused by heat either on the mobo or generally inside the case. I've ran the OCCT test and the clocked chip passed it at max 75c.Any ideas guys?

Hi there, I may have a bit of experience with that. does it freeze for good, or continue after 5-6 minutes?does it happen without O/Cing?do you load a flight plan generated by a third-party tool?

Hi,I don't know if it's ok after 5-6 minutes, I don't believe I've waited that long, you know how it is when it freezes, you just get frustrated and reset the box. I'll try it this evening, ORD-DEN should be a good testing route.I did not try it without overclocking, I will this weekend as I'll have more time for all this. I create flight plan in FSX then import it to REX for weather.Were you able to fix your freeze ups? If so, how if you don't mind me asking?Ps. I forgot to mention, when I ran the OCCT tests with this case closed, it did get hot only after two minutes. I now run it with the case open, the OCCT tests like i said were in a ballpark of max 75c. I have an older Antec server case with two 120mm fans, which I think could not be enough.Jacek :)

Definitely run the flight w/o the clock. You seem to have a mild clock for that CPU but FSX puts demands on the subsystems that won't show in benchmarks. I've had clocks that passed OCCT & Prime95 for hours and crashed in FSX in minutes. Eliminate the clock as a possibility and go from there.Also, I didn't see your system specs except for the CPU clock - memory could be an issue also. Video card could also be the culprit as well as the sound card. A little more info would be helpful - but do the no clock test first.Good luck,Vic

I have fixed two different freezing issues on two different machines, this is why I need your answers first before I can tell you which one it is. Freezing for good is most likely a hardware problem. Overclocking, RAM, heat, GPU, etc.Freezing for 5-8 minutes, then continuing as normal, is more difficult to pin down and seems to have to do with multicore operations. I have it happening on two completely different machines, and only when flightplans are loaded through the FSX interface, never in VFR flight. You also should post your graphic card and driver version. But lets find out if the system recovers by itself. It would be weird because that recoverable freezing happens very very rarely and is not connected to hard issues. You say you have it on every flight, so I am guessing heat's the problem. 75C could easily mean 90 and more on one of the cores.

Sorry about that guys, here are the specs:i7 920 @3.8GHzAsus P6T Mobo (Standard)OCZ Platinum 6Gb DDR3 1600GTX260XP64 SP2FSX SP1&2I just got a Coolmaster CM690 case this evening, it seemed to brought down the temps from 44-48 to 37-41 at idle. I will be ordering additional fans from Newegg tonight to bring the temps down even more.
