Hello,

a month ago I bought a new video card Gigabyte Geforce 660 (N660OC-2GD). Now I have still problems with calculations and I lost a lot of time. Please can anyone help with this?

Here is my old computer system (Win 7):

and here is the newly installed system (Win 8):
http://www.gpugrid.net/results.php?hostid=151360

Whenever I pause a job, display driver crashes and displays the message that "Display driver stopped working and has recovered". But it happens without pause. Normally I work on the computer (using mail, word, excel, text editor), but it happens at night, when I'm not at the computer.

I have a problem here on the GPU Grid, my other projects go well (DistrGen, PrimeGrid). I tried to stop the calculations on the CPU (project Asteroids), but it did not help.

I also tried older drivers but without success. I tried in the Windows registry set a longer TdrDelay from 2s to hardcore 120s. Now when I pause work, so the picture freezes for a few minutes (can not move the mouse) and after two minutes restarts the video driver and everything is working again.

Is in a BOINC an error log that would help me find out what happened?

Sorry for my English, it is Google Translate.

Thanks for reply.

Ok, thank you for reply.

Sometimes I play games and I need to pause boinc. I'll wait for short runs, until it is somehow resolved (eg new drivers).

Sometimes the driver restarts without suspension work.

If you get a driver restart, when the GPU app stops running for example, and you get an app error, close Boinc, wait a minute and open Boinc again. The GPUGrid WU will usually resume from it's last check point. If it doesn't then the registry hack might be useful. I suggest people only try it if they are getting repeated app crashes.

I think this is the reg hack you were referring to, but there might be alternatives:

Here is the regedit that should stop the driver has stopped responding/restart issues in Windows. Copy and paste all the text below into noterpad. Rename it fix.reg (or any name you'd prefer with .reg extension)
Right click on it and open with it Regeditor. You'll get warnings about editing the registry can botch things up, do you want to proceed. Hit yes and then reboot. Hopefully that will stop the issue. There is one negative I have found when doing this. Some GPU projects can stumble when you OC your card too much. If that happens you may get a BSOD instead of a driver reset. Happened to me once on Einstein@Home. I lowered the OC and no more problems.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Watchdog]
"DisableBugCheck"="1"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Watchdog\Display]
"EaRecovery"="0"

Do I understand it correctly that this change avoids "fake" driver resets, when the GPU wasn't actually hanging. But if you get a real error you're f*cked and probably need a hard reset, just like in the "good old times", before vid drivers could recover a GPU?

I also found some good information here:

However, I'm not going to be making any changes. The NOELIA tasks may sometimes currently crash the drivers, but I my system needs to work properly for other scenarios. I hope GPUGrid fixes their problem, as it seems relatively easy to reproduce it.
