Undervolt a GTX 1060

To undervolt a GTX 1060 whilst mining ETH, simply drop the power limit, and up the clock. Using MSI Afterburner.

Monitor voltage with GPU-z

Notes
Overclock the memory. +1000, no worries. 18mhs becomes 23mhs (always overclock 1060 memory - for gaming too. One hundred percent free performance)

At most with power and clock work, you will get 24 MH/s out of a GTX 1060, but this comes at a cost of ~140 at the wall (gross, small haswell system)

The ideal for a 1060 is 23.4mhs.

Power limit 65, with a clock setting around +140, will drop the voltage to 0.78v, and wattage at the wall to ~105

I am unable to acheive such mhs per watt with my Sapphire Nitro+ 470 4gb

Random combinations of clock and power settings can yield undesired volts/power draw, or crashes

Based on gtx 1060 WIndforce OC 3gb. Similar results on EVGA SC mini itx 3gb.

    Here are a couple more data points.

    MSI Gaming X GTX 1060 3 GB; Afterburner settings: power limit 65%, core clock +140 (2062 MHz boost), memory clock +1000 (9.6 GHz); Nicehash DaggerHashimoto ETH 23.4 MH/s (June 8, 2017); HWiNFO GPU Power 110 W, 1050 mV, 53 C, fan 87%

    MSI Gaming X GTX 1060 3 GB; Afterburner settings: power limit 65%, core clock -225 (1708 MHz boost), memory clock +0 (7.6 GHz); Nicehash DaggerHashimoto ETH 18.4 MH/s (June 8, 2017); HWiNFO GPU Power 88 W, 1050 mV, 51 C, fan 79%

    Hmm it seems different cards that I've overlooked before actually perform better than higher rated cards.

    Case in point:
    The GA Windforce OC 3GB actually performs better at 23.6 than the 6GB version of the same card at 23.4

    I'm also getting superb voltage at the wall at 23.4 ~96 for some cards

    Some cards get 24 easily, running at ~123 watt at the wall and a cool 55c temp - but was only testing for 10 min so likelihood of temp average around 59c.

    Here's how the Palit Super jetstream & dual fan models run. Managed to get the mem + voltage exactly the same, just the fan on the cheaper card gets a fair bit louder. I believe I could get the temps & hashrates even higher if I
    was running open bench, but I went for efficiency since right now they are sandwiched/crammed into a mid-tower(inwin 303) with barely 1cm gap. Still admirable for "budget" brand cards.
