Sometimes the GPUGrid supports the GeForce 10 series well.But when I used the GTX1080 to run the GPUGrid,the feedback information is always the "computation error",I don't know how to do with this situation.
System environments: Win7 64bit,Dirver 372.90+,[email protected](x64) + VirtualBox 5.0.18, secure software is closed ,and GPUGrid has been download"_cudart64_80.dll" &"_cufft64_80.dll".

- What is the exact make and model of your GPU?
- What does GPU-Z show for your "GPU Clock" value?
- Do you have any TDR logs (.log files in your C:\Windows\LiveKernelReports\WATCHDOG folder)?
- If it is factory overclocked, have you tried running it at reference clocks, by using MSI Afterburner to set a negative Core Clock offset value?

I'd start by ruling out the possibility that overclocking is causing the issue.

GPU applications can't run in virtualbox.
EDIT: At least it's not easy to make them run in virualbox.
EDIT2: This could be related to driver corruption. Try to uninstall / reinstall your GPU drivers. See this post.

I think they meant that their host has 5.0.18 installed (which comes with the latest BOINC installer)

I didn't overclock for this card.
AUSU ROG STRIX-GTX1080-A8G-GAMING
GPU Clock 1671MHz
And I only find .dmp files when I watched that floder

I had press your postings to operate, but the fault persists.

what means 5.0.18? The Recommended version of BOINC is 7.6.33

That GPU is factory overclocked.

https://www.asus.com/us/Graphics-Cards/ROG-STRIX-GTX1080-A8G-GAMING/specifications/

OC Mode - GPU Boost Clock : 1835 MHz , GPU Base Clock : 1695 MHz
Gaming Mode (Default) - GPU Boost Clock : 1809 MHz , GPU Base Clock : 1670 MHz
*Retail goods are with default Gaming Mode, OC Mode can be adjusted with one click on GPU Tweak II

===============================

The behavior sounds like the overclock might be too high. You should investigate, by removing the factory overclock entirely:

- Install MSI Afterburner
- Adjust "Core Clock (MHz)" to be negative, like "-63"
- Set the "Apply at Startup" option, if you want that clock to be applied at startup
- Install GPU-Z
- Verify that GPU-Z shows "GPU Clock" with a value of 1607 MHz, which is the stock reference clock for a GTX 1080, per:
https://en.wikipedia.org/wiki/GeForce_10_series

===============================

7.6.33 is the BOINC version. 5.0.18 is the VirtualBox version, which is a piece of software that can be installed alongside BOINC, and is made by Oracle, and is used to work on Virtual Machine tasks.

The stderr output of your tasks shows:

I take a look.But the Core21 at FAH & Opencl projcts at Einstein@home is normal.

These four files all be complete

If I may, please check your NVidia Control Panel settings in the "Manage 3D Settings" tab and ensure that "Optimize for Compute Performance" is set to off. GPUGrid, for some strange reason, will not work properly with the large CUDA address spaces and has not been optimized to work with Maxwell GPUs under such conditions.

I got this problem just yesterday too, and it made me hang with this for a whole day today.

After some researches I figured out the cause was different overclocking frequencies in my case.
I was using both Geforce GTX1050 and GTX1060 on CUDA processor crunching, overclocking GTX1050 by 160MHz offset, GTX1060 by 200MHz offset.
The issue always popped up when these graphic cards were set as above, and they worked smoothly at the factory manufactured frequencies and at the same offsets, strangely.
Now I put 160MHz overclock value to both, though GTX1060 has enough capacity to handle more computations.

Yeah, I tried graphics driver reinstalling that Retvari Zoltan suggested above, but I guess it was more related to overclock settings.

Hope this could be helpful to some other ones.

And one more thing,
I recommend not to push your VGAs to its overclock limits.
There could be a higher possibility of gaining computation failures, and it really was to me.

There are tools to use to test whether your overclock can be considered stable. For GPUs... Heaven, Valley, Furmark, etc.
