With version 9.7 I gained about 0.8MHz for each nvidia 1070 or 1080 ti card I have. Thing is that after some time or maybe hours (its random I think), the hashrate drops to 9.6 driver levels or slightly higher.
For example one of my rigs with version 9.6 was doing 232Mh/s eth and 2300Mh/s Sia. With 9.7 went up to 238Mh/s eth and 3000Mh/s Sia. It drops though to 231-234Mh/s eth and 2500-2200 Sia.
I noticed some drop to version 9.6 too, after hours of mining though, like from 232Mh/s for eth to 231Mh/s.
The drop rate with version 9.7 is more obvious now. I don't know if there is any solution for this.

Anyway, great job Claymore, thank you!
