To all of you wondering about lower hashrates with their GTX 1060-3,
as I said before here
https://bitcointalk.org/index.php?topic=1575547.msg19288923#msg19288923I won´t recommend the GTX-1060 with 3 GB because they have less cuda-cores, a lower bandwidth memory interface and usually lower base/boost-clocks.
GTX 1060-6: 1280 cores
GTX-1060-3: 1152 cores
... so now way to get the same speed.
I trimmed my 2 cards a little more with MEM + 600, now getting ~ 44.5 MH/s at daggerhashimoto,
still using 230W at wall with one core G4400 mining cryptonight at 49 H/s on top.
