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

(A 0 results google search term)

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

dupe

are the files set with execute permissions?

You're right, it's the md5 hash of the executable.

Now you've made one. I've made another.

I don't think so. Unless you run too many rosetta simultaneously.
Try to limit the number of usable CPUs in BOINC manager to 50% (options -> computing preferences -> use at most 50% of the processors).
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.

are the files set with execute permissions?

This is Windows, there is no such file attribute.

This is Windows, there is no such file attribute.

I also suspect a too aggressive AV program.
Whitelist the BOINC directory.

Boinc directory all ready excluded longtime.
Only 6 cores for Rosetta now(app_config)
PC is not overclocked, just finished one month Rosetta @ 12 cores without hickups.
Maybe the SSD is due for some garbage collection will check later.

Thanks for thinking along.

This is Windows, there is no such file attribute.

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

Sorry, I misunderstood you before.
Those permissions are set by the BOINC installer.
If they would be incorrectly set (later, by the user), none of the tasks could run.

I see that you have at your system #403376 a mix of succeeding WUs and failing ones after a few seconds.
On the hardware's point of view, this might be compatible with:

-1) Some failing memory chip at graphics card. Depending on to what memory chip(s) are assigned the initial data for a certain WU, it will be affected if data are assigned to the failing chip.
I'm afraid that if this is the problem, there isn't solution other than replacing graphics card (or, less drastic, trying first to underclock memory chips ).

-2) Some problem regarding the ones described on this post, relative to deficient electrical contacts.

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

Thank you - I just installed it.

I've never seen a problem running GG & Rosetta together. Rosetta is a memory hog but the worst I've seen is some WUs may be "Suspended waiting for memory."

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

Something to try to help diagnose what resource is running short. Not necessarily permanent after the diagnosis is finished.

My answer would hijack this thread, so I've made a new thread for it.
