Scrypt Adaptive-N keeps restarting

I am trying to GPU mine using scrypt adaptive-n but, I keep getting this message "Your miner was restarted automatically after a sudden stop at 00:41:48.", however CPU mining works perfectly

    The log just says

    And then it gives the error message mentioned before

    Interestingly, it starts working if I run at the same time as ethminer, but as soon as I stop ethminer it gives the error message.

  • That's very peculiar, but it might suggest an issue with the intensity you've got the miner set to. Sometimes this happens if the intensity is too high or low for the GPU but maybe ethminer running simultaneously is taking up too much of its runtime for it to cause the crash.

    I wouldn't normally recommend running more than one GPU miner on the same GPU at the same time though!

    I get the same thing at intensity 8. If I set intensity below 8 or above 22, I get this

    Starting…Please set an Intensity of 8 or higher [2018-01-25 18:10:54] /var/folders/vx/jv8mhny52rz4g5hn3dkpt7m40000gn/T/AppTranslocation/E09644E9-85BD-4916-8DA2-9D26C7845F02/d/MacMiner.app/Contents/Resources/vertcgminer/bin/vertminer: -I: Invalid value passed to set intensity

  • When I try to take the Resources folder out of the package contents of MacMiner and try to run vertminer from the terminal to mine that way, I get "Bus error: 10"

  • I'm not sure what's up with that then. You don't need to take binaries out of the app package to run them at the command line, they're actually linked to various other libraries in the bundle so it's best to run them where they are. Could you try giving it a shot with the sgminer here? http://macminer.fabulouspanda.com/commandline/

    If that works I'll switch the scrypt N GPU mining function from vertminer to sgminer

  • I tried sgminer, it started with n factor 11 and got these errors

    I tried running vertminer inside the app package it justs does this everytime it runs

    This is what happens when I run it at the same time as ethminer, if I don't do that it gets the "Bus error: 10" immediately. So the "Bus error: 10" seems to correspond to the constant restarting done by MacMiner. And the higher the intensity is set, the faster the bus error comes

  • I've had a good look in to this and didn't get either of those working with scrypt-n, so I've compiled sgminer-gm and tested that which works and has shares accepted for me using the following:

    ./sgminer --algorithm scrypt-n --nfactor 11 -o stratum+tcp://eu.stratum.garlicpool.org:3333 -u my.worker -p x -I 11

    I've added to the other sgminers here:
    http://macminer.fabulouspanda.com/commandline/sgminer/

  • I've replaced vertminer with sgminer-gm in an update to MacMiner now.
