Hello everybody, I'm new to this forum.

Yesterday, I updated Win10 x64 Pro from 1803 to 1809. In the next step, I installed the newest graphic drivers:
- nVidia driver 418.91
- Intel driver 25.20.100.6519

Before updating, I could use both Intel UHD 630 (for SETI) and nVidia Geforce GTX 1070 (for GPUgrid.net, etc.) simultaneously.
Afterwards, Intel UHD 630 is not detected by BOINC any more.

Reinstalling BOINC 7.14.12 with deleting cc_config.xml did not solve the problem.

In device manager and task manager, both GPUs are detected.

My PC:
- Asus ROG Z170 Gene VIII
- Intel Core i7-7700k
- MSI Geforce GTX 1070 Aero ITX OC 8G
- 4x 8 GiB DDR4-3200 by Corsair

Do you have some ideas how to solve my issue?
Please let me know if you need additional information.

BOINC log:
Hint: My SETI settings allow SETI to use Intel GPUs only.

BOINC not detecting a GPU - especially when it has done before without problems - lies primarily in the drivers. Make sure you clean install the Intel GPU drivers, or in the least uninstall the previous drivers, use a cleaning program such as Display Driver Uninstaller to clean remnants (in Windows Safe Mode!) and then install the new drivers. Also make sure that Windows 10 does not install its own drivers again, as it has a tendency to do so, lots of times without telling you.

It's been a long time since I've used my iGPU but won't you need the cc_config.xml and use_all_gpus to enable a 2nd GPU? That's after BOINC recognizes the iGPU with OpenCL support of course.

<cc_config>
    <options>
       <use_all_gpus>1</use_all_gpus>
    </options>
</cc_config>

Apparently his only running Seti on his iGPU. Not sure why. But I agree, if he wants to run both he would need that cc_config.xml file entry.

Tag.

Your "it".

BOINC not detecting a GPU - especially when it has done before without problems - lies primarily in the drivers.

You have been right.

and then install the new drivers.

No, this caused my issue!

I tried a lot of different Intel driver releases:
- 25.20.100.6577 (recent): NOT working
- 22.20.16.4836: working
- 24.20.100.6346: working
- 25.20.100.6471: working
- 25.20.100.6519: NOT working

So the workaround to solve my issue is downgrading Intel GPU driver until the incompatibility between BOINC and the recent Intel GPU driver has been fixed.

This works as intended.
