The Afterburner fan profile appears to take effect only if I leave Afterburner running from the console, but will then limit the temperature to 62 C.

I'm about to try a small change aiming for 60 C.

Not the most intuitive setup, for sure. I fiddled with it a bit, and never felt comfortable that I knew what it was doing ...

. . That is surprising to me, I found the fan adjustment very straightforward. Set the curve of how you want the fan to respond to GPU temps and let it go. It was only a matter of moving the set points to where you want them, even add more set points if you want to be creative :)

I may have found the way to make it run without much attention - click on Fan Speed, then Settings, then General, find General properties, and make sure both Start with Windows and Start minimized are checked.

Now 60 C and Afterburner started automatically after the last Windows restart. It will take a day or two to tell if that stopped the invalids from the 560.

Hi all,

Thank you Richard Haselgrove for this application. I have installed lunatics v0.45 beta 4 without any troubles, working on a GTX 780, a HD 4600 and a i5 4670k.

In progress tasks were not killed and they seems to work much faster. Especially, v0.44 was only using 60-90% of the gpu and it is now above 90%.

Cheers

Still some invalids at 60 C. Now trying for 55 C.

. . OK, if at 60 C or below you are still getting invalids then there is something else at work as well. I am not familiar with the needs of the GTX560s but I think you may have some driver issues to resolve. Maybe Wiggo can help you there .. he runs 560s.

Agreed.
What's the CPU temp look like?
Are you pushing a marginal power supply too far? I just had that happen, added a second 750ti to a box, had errors all over the place, replaced the PS and not a single error since. Was within limits, PS must have just been tired and 12v was weak.

Was within limits, PS must have just been tired and 12v was weak.

Like me replacing one of my GTX 750Tis with a GTX 1070. Load on the PSU was still less than 50% of it's rating. 3 days later it was dead, and that horrible dead electronic device smell...
Did an autopsy & found one of the chopper output transistors split apart. Cause- the incredible amount of dust that had accumulated in the PSU heat sinks over the last 5 years. With the GTX 750Ti it probably would have lasted another 5 years, the extra load of the GTX 1070 was enough to push it over the edge.

Something to keep in mind when cleaning out the accumulated dust from the CPU & GPU fans and motherboard heatsinks- unless you've got lots of compressed air to blow back though the PSU, it's going to accumulate a similar amount of crud as the rest of the system unless you pull it out & physically disassemble it & clean out the dust that accumulates in there.

I have a question. Is there an ETA on when this silliness with the 100% CPU usage (when crunching on GPU) is going to end? I have a GTX 970 specially bought to crunch, instead of the CPU and now my brain hurts every time I see the full CPU core when crunching on GPU.

If you're planning on using the GTX 970 to crunch instead of the CPU, then it's no loss the CPU supporting the GPU is it?
You can run the SoG application without making full use of the CPU core, however it does a lot more work with the full support of that core.


EDIT- i'm pretty sure that by default the current SoG application supplied with the Lunatics v0.45 Beta 4 application minimises it's use of the CPU.

Just add -use_sleep to your comandline text file if you are on OpenCL.
This will reduce CPU usuage significantly but also reduce speed.

Yes, I count my blessing that I have a compressor in my shed, with a tank and blow nozzle. Amazing what 100 psi can dislodge! Not fun trudging through the snow in winter, but ...

. . Sorry to hear about your loss. But you make a very good point about cleaning the PSU as well as everything else.

Hi Songbird,

. . May I ask what you are running?? Stock? Lunatics? And CUDA or S0G? There are tweaks to release the CPU from the monopolistic grip of SoG if you want to.

. . For the GTX970 if you are running SoG, in the command line file in your BOINC data directory "Projects/Seti@Home" called "mb_cmdline_win_x86_SSE3_OpenCL_NV.txt" (there may be _S0G after the NV if you are running r3500) [you can edit it with a text editor like Notepad] add "-high_prec_timer -use_sleep" you will then find your CPUs are no longer wholly monopolised.

. . Yes Grant the default in r3500 should be -use_sleep but it doesn't hurt to have it in your commandline to be sure :)

. . Actually r3500 maximises GPU utilisation very well.

. . I would find that useful occassionally, but the pressure packs of compressed air can do a reasonable job too.

. . Just have to find someone who stocks them :)

At 58 C, it's not clear yet if I'm still getting invalids or not. GPU temperatures higher in early mornings than later in the day, though.

Afterburner usually shows fan speed at 100%, not changing when the computer's loudest fan switches to a higher speed.

It looks like time to try harder to look for dust inside the power supply.

. . If the fans are running at 100% all the time then it is doing everything it can to maintain the temp, so 58 is about as good as it gets unless you pump more airflow into the case. But 58 C should be fine for continuous operation of a GPU.

. . It sounds like pulling out the PSU and opening it up is the next step. I hope it solves the problem for you.

I opened the power supply and blew the dust out. No major concentration of dust there, so I also blew out any other dust I could find.

The 560 fan is at 100% but rather quiet, so I suspect that the loud fan was for something else. GPU temperature about 60 C.

CPU temperature is up to 77 C, so is there a similar program to provide a fan profile for the CPU? CPU tasks from other projects running on all but one of the CPU cores.

Rather open air path inside the case, with fans already at every place air should go out.

Probably at least 30 hours before I can tell if the invalids are gone.
