Hi minerx117 a.k.a the infamous Nemos

. First of all, thank you for the miner. It's more than awesome. I do have some questions though. I am currently running a single 1070 and switching between zpool and mph.
1.) For some reason, when I use zpool24hour, it mines and stays with Tribus. It's profitable but is this normal?
2.) I see x11 in zpool but I'm not sure how to add it to the algo list or can you recommend me a set of algos for a single GPU mining?
3.) What do you think is the best core/mem clock settings for the 1070? I currently have +120 core and +780 mem (I tried 800 but gives out invalid id errors and other errors as well). The 800 setting worked/works with nicehash and awesominer.
I'm fairly new to mining so please feel free to correct me in any way. Again thank you!
