8800GTS..

One other thing.. notice how mine just displays the temp and the clock?

I just leave those two enabled since that is all that I need when I check it and TEMP is required for fan control... no reason to have the rest of the monitors running if you you are not using them. As I recall RT displays an entire list by default.

The TEMP graph is the only thing needed for fan control. If needed I check the TEMP by dragging the mouse across and it shows the timebase... I think its 10 minutes worth of graph as I recall so you have plenty of time to drop and check when this crash occurs

[quote]Yeah... this is gonna be head-ache to nail down.. but it's fun to learn this stuff..

[NickN]

one other thing too... the only thing that would lead me to think it is not heat, is if the problem happens when accessing that dial you were talking about and not before...

if you don

New data...

With RT running (fan locked at 30%), it didn't take but 5 minutes for it to crash. Same pre-crash symptoms, but no dial use. Complete crash, but the GPU core temp was still over 60c by the time I rebooted.

Then with RT running and the fan set to 100%.. I flew for 10 minutes (full screen),, then went to windowed screen.. and the core temp was only 41c.. pretty much stayed in the low 40s, going in and out of full screen (to check RT).

Next I did an extended flight with the fan set at 60% and periodic temp check showed nothing over low 50s..

Safe to say I have a heat problem.. and that whatever weird work the GPU has to do to display the spinning vertical speed wheel, and the changing digits (AND immediately following a VC pan), probably pushes it over the edge ?

Interesting too... if I set the fan speed via RT and then close it.. the fan setting stays. No evidence of it running via task manager (processes or apps).. so I guess it doesn't HAVE to be running.. but I  DO   have to run it manually (until I set it to run a profile automatically)..

The problem seems to be solved (gonna do a long flight in a sec), but it still disturbs me that nVidia ships cards that will overheat without running something like RT...

And.. the fact that I was descending into complex scenery after a long flight.. probably had something to do with it ?

All I've ever run was the nVidia control panel... and I can tell you that the fan never got up near 60% (if it sped up at all)... because even at 60% it's audibly different.

During my research.. I saw several people complaining that their fans never sped up automatically...

[Brett_Henderson]

WAIT ! ...  I do have  SpeedFan on this computer... would just having run it long ago while O'clocking the CPU, cause this problem ?

[quote]WAIT ! ...

Excellent... thanks so much...

I like messing with this stuff anyway.. and even if I fry the card, it's cheap tuition (and an excuse to get a 3870X2)...

To expidite just being able to fly.. I'm going to just force the fan to run at 60%.. and check the box to load that fan speed when Windows boots.... then tomorrow I'll customize RT...

And then, if I ever worry about resources.. I can kill RT from task manager, and that fan setting stays..

Thanks again.. (you're much too patient)

I realize your original post is over a month old, but I was wondering if you've found a solution to your problem?

Brett, if you're going to fry your GTS, instead, then send it my way and tell your wife that it broke.

That'll be fine.. lol     (except that I don't have a wife  ;)  )
