Installed version 398.36 of the nVidia driver on an ASUS Poseidon 1080 Ti and ASUS Poseidon 780 but it does not appear to be compatible. That version includes CUDA 9.2.

Since the update SETI will not use either nVidia card as it has been.

Suggestions?

The relevant log lines:

Which operating system?

I see a Linux box and a Windows box.

Advice for the windows box starts with look in the Device Manager and make sure it shows both GPU's to be happily installed.

I have had the log report a "gpu missing" result when the driver(s) where not correctly installed.

I have driver 391.35 installed.

If the issue is with the Linux box I hope someone else chimes in.

Try to reinstall the driver, but this time use the "clean install" option in the installer. Both your GPUs support CUDA (at the time of writing this, no matter which version). If reinstalling doesn't give you the option to do the clean install, uninstall the driver - probably wise to run Display Driver Uninstaller here (from Safe Mode!) - then reinstall it.

Thank you for the reply.

This is a dual-boot box with both Windows 8.1 and Debian Linux. It's primarily a compute box for my physics work. Spends 99% of the time pegged - but is water-cooled.

The solution was to downgrade to an older nVidia driver version. Windows kept auto-installing the latest but that is broken or not compatible with Seti at Home. The last two releases are both broken actually - 398.36-desktop-win8-win7-64bit-international-whql.exe and 398.82-desktop-win8-win7-64bit-international-whql.exe. Don't know about prior releases.

Currently running 388.71-desktop-win8-win7-64bit-international-whql.exe because it works with Seti at Home and the physics software we've written.

Hello Todd,

I was facing the same issue. And after not recognizing the issue I tried really everything and made things worse.
Your hint in this topic and a project reset helped me finally.

Thank you very much!
Greeting from Germany,

Viktor
