Does anybody made this miner work on large rigs (17+ cards)?
i've tried 12x588+7p106-100 on HiveOS, but i've got only "segmentation fault  waiting to cooldown"
that's interesting. make sure you have like 70GB of virtual memory(swap file) and maybe try two instances of the miner with -amd  and  -nvidia options  (or -di option if it supports such a large enum...) and please report back  Smiley
i'm using Linux
i've tried 2 instances of the same miner, i've tried 2 instances of different miners, i've tried to mine with 16 cards while there were 18 in the rig.... always the same thing

I'm not sure what segmentation fault there is, but it very well could be that the OS cannot map all the memory of the GPUs properly. try to play with the drivers and reduce number of cards and see where it dies on you. also mb bios could be an issue. (I'm running 12GPU rigs since the very first AMD driver version that started to support more than 8...)
everything works great with 16 cards or less. and there is "segmentation fault" in the miner log
