Hello,

I'm running GPU grid on a couple of systems and recently a LOT of my tasks are failing.

State: All (1274) · Valid (307) · Invalid (0) · Error (958)

All on this host: http://www.gpugrid.net/show_host_detail.php?hostid=500099

Antivirus reports no specific activity, Windows is up-to-date, drivers are up-to-date, card are not manually overclocked. (other GPU projects work fine)

There is nothing obviously wrong. I'm afraid your card may be failing, or factory overclocked (not expert).

The WU I looked at failed for 2 others as well before it completed.

# Engine failed: Particle coordinate is nan

{nan = not a number}

I don't see anything. Sometimes you just need to reboot. I run Linux and I always set a 16 GB cache. Yours is only 2 MB but maybe Win10 dynamically sets it. Are you running more than one WU per GPU? I recommend only running one WU per GPU. I have an FX-6300 and it's fine. I like to leave a CPU thread open for overhead etc on all my computers.
