Had about a dozen tasks crashing.
Anyone some idea what the errorcodes mean?

ERR_NO_APP_VERSION -195 - BOINC couldn't find the application's version number.

Is the acemd3 and wrapper executable in the GPUGrid directory?

That's a good wiki, thanks!

Yes both acemd3 and wrapper are in project directory.
Only noticed several files, incl. acemd3 have a hash or so behind the file extension, first time I see that.

acemd3.exe.13c31bf624c1a4246bef60d9b5ab664d

dupe

are the files set with execute permissions?

Have removed/rejoined , still the same ( 60% erroring out.)
Maybe Rosetta and GPUGrid together cause IO conflicts.

This is Windows, there is no such file attribute.

Is your i7-6800K overclocked? If it is, try to reduce its BCLK core ratio and BCLK uncore ratio.
You can try to exclude the C:\ProgramData\BOINC folder in your antivirus software.

while it may not be the issue at hand, Windows definitely does have execution permissions.

Had about a dozen tasks crashing.

Symptom: A GPU normally working fine starts to fail tasks intermitently with no apparent reason.
Remedy: Extract GPU and memory DIMMs, clean contacts and reinsert.

ServicEnginIC , you come close! ;-)

After opening the case found 'a bit more' dustbunnies inside as expected
(cleaned out pc late march).

If I would have also checked MB temps, instead of only GPU temp, perhaps I would have noticed.
Now running happy without crashes (fingers crossed).

Thanks again for all input

Is there a program for checking MB temperatures that will run under Windows 10 on most brands of computers?

I'm using https://www.hwinfo.com/
in sensormode - if your mb have an sensor it shows the value,
it also shows values from GPU

Try to limit the number of usable CPUs in BOINC manager to 50% (options -> computing preferences -> use at most 50% of the processors).

Zoltan you lost me on this one. Why 50%??? I would think 92% (11/12).
