I tried searching but couldnt find. Probably bad bitcointalk search feature.

I have a rig with 4 x GTX 1060 and 2 x GTX 1070 (both EVGA). I have set core to 10 and memory to 1500. Wattage for 1060 set at 85 and 1070 set at 100. Mining ETH claymore.

The 1060s are mining at 24 MHS. 1070s are mining at 32 MHS. Total 160 MHS. But once in every minute, they drop by 3-4 MHS total. Makes me feel if I am overclocking too much and undervolting too much. They have not crashed yet (running only for last couple of hours). Any thoughts? Is +1500 memory too high? Should I reduce it? But I see lots of posts that EVGA 1060 is very much capable of 25 MHS and 1070s at 34 MHS. No idea how to hit that level.
