I got the same residues, when dobbelchecking on the exact same machine, so I'm only reporting 7 primes. Anyone has any idea how that is possible to do the same test twice and get two different results?

Errors could be for a number of reasons:

* Faulty LLR code -- extremely unlikely
* Overclocking too much.
* Incompatable computer components
* computer components not set properly
* faulty components such as bad RAM -- check with memtest86
* bad operating sytem -- maybe with virii
* hacker altering results

But are we sure that we have not lost any primes in this range ? (for example a prime could have an erroneous residue (different from zero) on your PC ).

I'm not sure, but when all come to all, the computer is not showing any mistakes in the BOINC projects it is running, like PrimeGrid forinstance, so the problem must be with LLR... I'm not sure, but if I don't get an invalid result from PrimeGrid then I have a hard time to see ow it possibely can have something to do with my computer And also if anyone wants to double check, feel free to do so, actually maybe we should ask rytis to do so, then to see if we get different results again... but why should i have been hacked? I havent downloaded any files, and I've reacently cleaned my computer for spyware...

Maybe we should PrimeGrid to Check the entire K space, first from k=1 to k=25 G, then there will be done doublechecks of the entire k space, and errors will be found emidiately :) So what is your oppinion about that?

Regards!

there is not that much point in double checking, as the tests only last very few longer if k increases. and the possibility for a test to be prime is the same in all ranges. so just test untested ranges...
