This is often what I get while crunching SANTI short run tasks. I can complete one task, and the following two error out.

Honestly, GPUGRID is the only project with such a high failure rate. I don't know what's wrong, but these tasks are very buggy

I think it should run OK at 77 C. If the temperature decrease doesn't fix the problem then maybe it's clocked too high?

Going through the tasks that have failed on your system I notice that the second iterations are almost always successful on 5xx or newer GPUs which leads me to believe the tasks themselves are not buggy. The second iterations seem to fail on 4xx GPUs. I must admit my sample group is small but it makes me wonder if older GPUs have the required compute capability for SANTI tasks.

I run GPUGRID only on the GTX 560. The GT 440 is used for other projects (Milkyway/Einstein). Driver version is latest stable 331.20

I've been able to crunch 5 consecutive tasks in a row, without a single failure thus far. I'm crunching my 6th task now and will see if it'll succeed

I think the problem is fixed. I've crunched 12 short WUs in a row, without a single failure. That extra fan I added seems to have helped :)

That's good to hear but I'm surprised it produced errors at 77 C. This spec sheet from NVIDIA claims the max. temperature is 98 C, not that one would ever want to run it that hot, but it seems like 77 C should be low enough to give error free results. So I wonder what software you use to check the temperature and does it give the temperature of both cards? Is it possible you reported the temperature of the other card which was getting better air flow and likely running cooler?

The NV center under Linux separates both cards pretty well.

Yeah, I did that. Reduced temps by a few degrees. My case really isn't made for multiple GPUs, as even on the bottom there isn't much space open

GPUGRID now set to no new tasks on this computer, probably until
something relevant is updated. Tasks still running on my other
computer, with a slower GPU.

GTX 560, at stock speeds.

My case isn't suited for multiple GPUs either, but I manage it by using Precision-X to set a custom GPU fan curve where it will go maximum-fan before hitting 70*C, thus keeping GPU Boost at maximum clockrates, while keeping temperatures low enough to process tasks successfully. You might consider doing what I've done. (Despite being made by EVGA, any nVidia user can register/download/use Precision-X freely... though, not sure if it's available outside of Windows).

that script could come in handy :)
links please?

Actually I meant I would provide links to the various bits of info I have found scattered around the 'net concerning how to reflash BIOS on NVIDIA based cards. I didn't mean the script as I felt that's not a good solution for managing fan speed however, if you are interested then I will provide it. And it does more than just control fan speed. It shows various info (freqs, usage, etc) which might be useful for anybody running without a desktop. I've been playing with gnuplot too and have been thinking the script could save interesting, plotable data to files and provide possibly informative graphs, even collate those with task type history or...

So, I'm tidying it up a bit so you can get it going without too much trouble. I'll post a download link in a few hours. Depending on feedback I might put it on Github so others can critique/add/improve/whatever.
