GTX 1060 Mining Speed Hash Rate Tweaks and Adjustments for Equihash Mining Zcash or ZenCoin

Last updated November, 2017

I want to mine ZenCash, and with my GTX 1060 6GB cards I’m currently getting about 255 sols/s using my optimized Ethereum or Ethash settings that I outlined here

With those settings, I am getting about 508 Sol/s to 510 Sol/s and consuming about 171 watts. According to the ZCash GTX 1060 6GB hashrates for my specific EVGA GTX 1060 6GB SSC card, others were seeing up to 350 Sol/s for each card – so there’s definitely room for improvement!

Overclock Settings GPU 1 Hashrate (Sol/s) GPU 2 Hashrate (Sol/s) Total mining rig power draw (including motherboard/power supply etc)
Stock, no overclock settings 297  305  263 W
Core + 50 MHz 304 308 267 W
Core + 100 MHz 303  314 270 W
 Core + 150 MHz  crashed  crashed
Backed off Core + 125 MHz 306 316 268 W
 I put the Core clock back to stock and played with the memory overclock to see what sort of max hashrate I could get without crashing.
Memory + 500 MHz 312 310 270 W
 Memory + 750 MHz 315 310 275 W
 Memory + 1000 MHz 321 317 277 W
The GTX1060 GPUs could take 1000 MHz overclocking without crashing (they could only do 950 MHz on Ethash) so I added in some Core overclock too
 Memory + 1000 MHz, Core + 100 MHz 332 325 282 W
  Memory + 1000 MHz, Core + 125 MHz 329 337 287 W

At these settings, EWBF is reporting efficiency for both cards of around 2.7 – 2.8 Sol/Watt. Without adjusting the power targets, are cards are running around 73 to 75 degrees which is acceptable, but putting out more heat than our power optimized Ethereum mining rig.

Profitability wise, it is the same as mining Ether (according to WhatToMine).

We are making more mining Zencash, Zcash, or an equihash coin, but after paying more for power, our profit is 1 cent per day less ($1.94 profit instead of $1.95 profit) than Ether and we’re putting out way more heat (10 degrees more per card) that we have to get rid of. In the winter time this might not be too bad, but in the summer it would require another fan. Also, at the higher heat levels the cards may not last as long.

Let’s see if we can adjust the power target in EVGA’s overclock utility to improve those numbers.

We can manually increase the fan speed (rather than leaving it on ‘auto’), and when it’s put up to 70%, the card temperatures were lowered from 72 and 75 degrees down to 62 and 66 degrees, but the power was also increased by 3-4 watts.

Instead of increasing the fan speed, let’s see what happens if we leave it set to ‘auto’ and then lower the temperature target down from the default 83 degrees C.


Overclock Settings GPU 1 Hashrate (Sol/s) GPU 2 Hashrate (Sol/s) Total power draw (including motherboard/power supply etc) Sol/W Total Rig
Memory + 1000 MHz, Core + 125 MHz 329 337 287 W 2.32 Sol/W
Since we found these to be the max overclock settings, they will be left alone and we’ll play with the power target
 Power target 80%, temp target 65 degrees  305  302  250 W  2.428 Sol/W
Power target 70%, temp target 65 degrees  298 284 191 W 3.05 Sol/W
Power target 60%, temp target 65 degrees  292  281 185 W 3.02 Sol/W
Power target 50%, temp target 65 degrees  289  277 179 W – crashed after a few minutes
Power target 40%, temp target 65 degrees  249 250 156 W 3.19 Sol/W

With these sorts of numbers, it brings my profit/power usage a little closer to Ethereum, but actually at 100% power draw is where I am the closest with only 1 cent of total profit per day difference.

Something strange is going on and I’m not sure what – when I bump the power target up to 110%, my power usage drops?! I’ll have to go back to the drawing board:

Power target 110%, temp target 65 degrees 296 286 186 W 3.12 Sol/W

After much confusion, I started fresh and adjusted settings. Using the top core speed from the first chart (at the top of this post), I then upped the memory overclock until it crashed, and backed off to +400MHz, and then started playing with the power limit until I had some good efficiency and overall power usage. Here’s where I landed, and it’s been running stable for 6 days:

Power target 60%, temp target 68 degrees 306 Sol/s at 85 Watts 306 Sol/s at 88 Watts 3.5 Sols/W

  1. Hey there, I just set up a 6 X 1060 3 GB build mining bitcoin gold, making about $12 a day. I was going to see if you wanted to chat and swap some ideas, trials and errors so we can both benefit with the most efficient rig settings.

  2. Hey thanks for the great step by step tuning guide. I followed your methodology for my Galax OC GTX 1060 6gb and my numbers for final result were:
    core +200 memory +400 power limit – 75 temp limit – 65c (actual running temp was 63c)
    sol/s 325
    sol/watt 3.63
    watts 87

  3. Hi all running GTX 1060 ssc 6gb. My MSI Afterburner OC settings:
    Power: 75%
    Temp: Linked
    Core Clock: + 140
    Memory Clock: 990
    Fan Speed: Manual 40%
    Hash Rate: 345 sols/s – 352 sols/s
    Sols per wall: 3.86 sols/w

  4. I’m using a EVGA GTX 1060 ssc 6gb dual-fan and getting 326/336 Sols w/EWBF Cuda miner.
    Power= 130W
    Core= +100
    Memory= +600

  5. On 1060 -6G is this good? Is this 2.68 sols per watt? My setting is core 125 MHz 500 power 200..
    GPU5 72C 82% | 328.7 Sol/s 334.0 Avg 178.5 I/s | 2.68 S/W 123 W | 1.00 100 124
