I was running Einstein@home and Milkyway@home tasks on my GPU successfully until some weeks ago, but now the downloaded tasks sit with a message about GPU missing. As you'll see from the log below, BOINC manager shows messages indicating that the applications use OpenCL but it's not supported.

Non-GPU tasks for other projects run OK.

I've looked through several threads with similar symptoms, and tried:

1) NVIDIA drivers downloaded from the NVIDIA website, with clean install and reboot each time: 388.13, 388.43, 391.01, 391.24, 391.35, (a few auto updates in between), and the latest 397.64; all -desktop-win10-64bit-international-whql.exe

2) Renamed c:\windows\system32\OpenCL.dll before clean install of 388.43 to make sure it was indeed replaced.

3) Uninstalled drivers using Device Manager, rebooted and reinstalled from downloaded file (forget which version now).

clinfo sits for a few moment, and returns an empty log. GPU-Z shows CUDA supported, OpenCL not supported.

I run BOINC manager as a standard user (not admin).

I've run out of trouble-shooting ideas.......

SOLVED, but in a way I didn't expect. I'll leave this post here so others know to try it.

I enabled the on-board Intel GPU, downloaded and installed the relevant driver from Microsoft (win64_24.20.100.6025.exe), and rebooted. Now OpenCL is supported on the NVIDIA card (log follows).

The log identifies both GPUs as index 0 - don't know whether this means anything. Task Manager shows them with indices 0 (Intel) and 1 (GTX 1070).

I'll post again if disabling the on-board GPU or installing the latest NVidia drivers break OpenCL again. What I suspect is that turning on the on-board GPU triggered an update of something, or there was a relevant update in the Windows drivers for the i7 chip...just a guess.

What you should also do is set Windows Update not to update your device drivers, as else, even when you install drivers from Nvidia.. if Windows deems these not new enough it'll immediately reinstall its own drivers, that lack the OpenCL component. OpenCL is a unified standard, but I wouldn't rely on the Intel OpenCL component to correctly drive the Nvidia GPU.

3) Uninstalled drivers using Device Manager, rebooted and reinstalled from downloaded file (forget which version now).

Did you reboot the PC after that? If GPU-Z doesn't detect OpenCL then BOINC won't either.
