Many thanks for reporting this. Unfortunately I couldn't replicate the crash you've experienced, tried it on 1050, 1070 and 1070ti and it all worked fine with -i 17. Was it 1060 or 1080ti that crashed?
The API, along with the windows version, should be available in a couple of weeks.
Also, I was wondering if you could benchmark phi1612 on your 1080ti for our stats?
Maybe it is a too high overclock, I really don't know as my rig is mixed with many different cards. tpruvot's ccminer worked fine, though. I've lowered to overclock on all cards that ran past 2050MHz, we'll see if crashes are still there.
The default ccminer api would be lovely, so the hashrate monitoring would work on Hive.
Lyra2z doesn't show improvement over high intensities, but it works up to -i 26 on 1080 Ti.
Phi however gets a 4% boost from a higher intensity. Testing on 1080 Ti @ 200W, -1000 memory, +120 core.
-i 20 (default): 37.8-38.1MH/s
-i 27: 39.5MH/s
