Dagorath -

Thanks, I'll stop running Tthrottle.

When the weather get warmer I bring the machine inside and put it in our mudroom. I just got the 470 so I don't know how it will do in there. At least I have options now. I do believe the heat sink needs to be re-seated with new grease though.

Afterburner allows you to set a fan speed curve. You pick the fan speed percentage based upon the temp and it will adjust it accordingly.

Thanks,
Chuck

OIC now what Snow Crash meant by fixing the curve.

Renewing the thermal grease is always a good idea with gear picked up used. Ya never know what dried out old piece of crud lurks under a used heatsink.

chuckbens - looking at your successful tasks I think you can get much more from you 470 as they are reporting many times "suspended by user request".
Maybe check that the BOINC "processor" settings:

While computer is in use = checked
Use GPU while computer is in use = checked
While processor usage is less than = 0

Thanks - Steve

While computer is in use = checked
Use GPU while computer is in use = checked
While processor usage is less than = 0

I have my computer usage set to less than 85% because I log into the machin with TeamViewer once a day or so (more lately) to check on it. I recently uninstalled Tthrottle on it - that may have been trying to throttle it back when the temp got too high. The temps are great now thanks to Afterburner!

Update -

I have another GTX470 card in a new Windows 8 dedicated cruncher. I am no longer running TThrottle. I am only using the MSI Afterburner. I have a "GPUGrid Short Run" crunching on the machine now. I logged in with TeamViewer and saw that the GPU is jumping from 90+% down to 0% over and over again. I can see no reason for this. The GPU temp is around 60 degrees and my fan is running at 80%.

Here are my settings under "Computing Preferences":
While computer is in use is checked
Use GPU while computer is in use is checked
While process usage is less than 0 - which means no restrictions
Use at most 90% of CPU time

I have no idea what is going on. I am running BOINC 7.2.33 and NVidia driver from 12/19/2013 - 9.18.13.3221.

Any more ideas?

Chuck

I just checked on my previous tasks - I shoulda done it sooner...

This task: http://www.gpugrid.net/result.php?resultid=7887082 is very similiar to about 40 others that have failed in the last 2 weeks or so. None have completed successfully.

I stopped taking any new tasks on that machine until I can figure it out...

Chuck

P.S. As soon as I killed the GPUGrid task my GPU use went steadily to 90+% and finished two Milkyway@home tasks in less than 5 minutes.

The reason that your GPU is stopping and starting may be that the CPU is starting and stopping. When you set CPU usage at 90%, it runs at 100% for a bit then stops for a bit. Try setting your CPU usage at 100% so the GPU can receive constant support from a CPU core. If you need to free up CPU resources try setting the maximum number of cores used for crunching to 1 less than the number of available cores.

Hope that helps.

I HATE those non intuitive settings, a non programmer would think like chuckbens did, 90% means run all the time but at only 90% usage, NOT 100% on for 9 out of ten clock ticks then 100% off for 1 clock tick! This ends up with a 90% average, but that isn't what most people think of when they see that setting. Most people think of it as a dimming light switch, not like a standard on or off light switch.

Since loading nvidia driver 335.23 when my computer starts up I get an error on the work unit that was being processed when I shut down.
And yes I did uninstall the previous driver before installing this one.
I have a GeForce GTX 670 on Windows 7
The last unit to do this reports "FATAL : Cuda driver error 715 in file 'swanlibnv2.cpp' in line 1963".

Any ideas please?

Try to exit Boinc and then shut down.

Your temps are on the high side. Suggest increased GPU fan speeds.

Thank you I will try that when current work unit has finished.
Sorry about posting in the wrong place have tried again now.
The link to how to ask for help doesn't work.

Hi Fred, Don't worry about posting in the wrong place, it doesn't bother anyone here.

It might be an issue with your system trying to shut down before the WU closes up properly (saves itself to disk), with the driver or with Boinc. I've a similar system with a similar GPU and driver but don't see this issue.

The Bit.ly link works for me, but it might depend on your browser, ISP or cached DNS info (start, run, CMD, ipconfig -flushdns might sort things out, if its not the browser).

This might be some odd security issue with the driver. Possibly being blocked by antivirus or the system, or just taking to long to load...

You might want to try adding a Boinc start delay option to your cc_config file, or creating a cc_config file and adding it:

<cc_config>
<log_flags>
<coproc_debug>1</coproc_debug>
</log_flags>

<options>
<start_delay>30</start_delay>
</options>
</cc_config>

You don't need to add the coproc_debug flag, I just put it there as filler.

If you (W7) need to create a cc_config.xml file, do so in the Program Data folder for Boinc, using a text editor (Notepad). The default location of the folder is, C:\ProgramData\BOINC (this folder will likely be hidden, but should open if you type it into Explorer).
