Hello everyone,

After Proth Prime Search GPU application update (1.38), i am receiving tons of invalid wus for my ATI rig here:

http://www.primegrid.com/results.php?hostid=179118&offset=0&show_names=0&state=4&appid=

First i thought it was the driver but than i reformatted the whole system and installed Catalyst 10.10 APP. I believe there might be a clash between Cuda ones and ATI ones during validation. Please guide me on this issue.

Thank you.

NOTE: No OC, no voltage change.

Sieve usually does not need to validated against a 2nd result. So your machine is sending back units that are somehow corrupt. Other than that, I am unsure what else to tell you.

I take it you were doing just fine at version 1.37 (or whichever was being used previously on your machine)?

If that's the case then I'd bet it's an issue with the program. If other people notice the same problem, then we know what's the cause (but not necessarily why...)

Hm, and if you reformatted your system then I guess there's no need to reset PrimeGrid and simply try getting the data files again.

Perhaps it's something wrong on the server side. It might think you're sieving the wrong range, sieving it incompletely, or sieving things already sieved...but that's just a guess, since I can't see anywhere you may have gone wrong.

Confusing!

It seems unlikely to me that TPSieve would send invalid results. It seems more likely that something might be wrong on the server.

However, I have been wrong before. :) And ATI on Win64 is about as far away from my testing scenarios as you can get. So could you please do the standard tests and let me know if anything goes wrong?

Ok, will do and will send you the results.

Do not install BOINC in protected application execution mode on Windows Vista and Windows 7 if you plan to use a GPU for doing calculations.

As per BOINC release notes:

Do not install BOINC in protected application execution mode on Windows Vista and Windows 7 if you plan to use a GPU for doing calculations.

Also ensure that .NET is correctly installed and that no screensaver is running.
Ensure that you can run OpenGL apps and Collatz (it should be up now). Then you should run the app from the command line.

Thank you for the advice. I'm pretty sure that NET is properly working.
But i don't know how to use Boinc command tool. I couldn't download it as well. or don't even know whether it comes with the usual software. If you treat me as a newbie on this issue, i will be able to provide the info:).
I checked the link given on the previous post but didnt know where to run it.

Check out one my hosts please:

What could be the reason of these invalidations? As posted previously, clean windows 7 with catalyst 10.9 stream 2.2 and i am pretty sure that there is no hardware problems. Invalidations became significant after the update of 1.38v

NOTE: The standart test did not give any error or unusual result.

You GPU WUs are running entirely on CPU. I believe that something is wrong with the drivers and it falls back to CPU? Ken, can you confirm?

I updated the drivers to 10.10 APP after a format and still it gives errors. At least it is stable now. It only gives invalid wus on this project. Tried DNETC and milkyway. A guide would be appreciated though.

Please?

Can you show the test output given in this thread (more the better)?

I opened this thread for seeking answers but it has been ignored and my rig has been producing producing %50 invalid wus out of total which is a disadvantage for both the project and myself.
I did the test and it produced correct answers.
Changing drivers didn't help. I even had format couple of times to handle the driver issues..
Observed no hardware failures. They run flawless on other computation processes. (Even changed with other gpus)..

Please inform me if you do something about it.

Maybe the SP1 causes this?
