Thanks for this. You were right when I reduced the core to 0 and increased the memory clock the hash rate increased. Interestingly though one card will take +850 and the other +700 at most. This seems odd.

Have an EVGA 1060 6GB SSC2. Samsung memory, but gets shit hashrates. My ASUS 3GB does 24-25MH, but this EVGA card barely pushes 21.

Both cards will OC the mem to +850-900 MHz but the EVGA just doesn’t perform.

Is there any hope?

people choose 1050 because actually you cant find any video cards in the world and the prices are almost troopled, so you can go with 1050 ti that is 60% of 1060 with speed so 2x 1050 is like 1x 1060

Yeah I think there is also an advantage to getting 'better' cards than 1050's (like 1060 or 1070) as you don't have to pay for the room to have more motherboard slots and cables taken up by lesser cards. Depending on the exact cost, it may be worth getting better cards to avoid all the additional costs with having lots of mediocre cards.

Hey fellow miners, my 1060 rig has been runing for almost 2 months now. I'm happy to say I was lucky with the memory and all my cards are with Samsung, 3 GB tho.
I've been tuning them up and down, playing a lot with the clocks. The final settings I found to be optimal are:

Power limit - 60%
Temp limit - 69c
Core +150
Memory +880

With 100% power limit I was getting a solid 25 Mh/s , up to 25.2 - 25.3 per card with Claymore Dual Miner. I dropped the power limit all the way down to 60% at the cost of about 0.5 Mh/s per card. My temps don't go above 38-42c with custom fan curve (mostly blowing at 40-50%) in a 15c room temp.

If I bump the power limit a bit higher at 80-85% I'm also getting solid 305-310 Sol/s on equihash. But atm the profit is less, even if same the extra electricity cost and higher temps on the cards are not worth imo.

I just wanted to share with you my personal opinion about 1060s 3 GB as I've read a ton of info about them and experimented a lot with mine.
About the settings:
Overclock your memory first, I think +500 or even +600 is a perfectly safe to start with if you've got Samsung memory, I started mine from +700 on the very first boot. Don't increase with more than +50 on each step. When you reach the maximum stable clock, start with the core - any card should be able to handle +100, but you can start from +50 and increase by +10 until you find the maximum stable setting. Then start lowering your power limit by 5% and see how low you can go without your hash rate droping like crazy. It depends on the algo you desire to optimize it for of course. You should be able to get your power down to 60-70% at the cost of 1-2% performance on Ethash and about 80-85% for Equihash or other algos.

Micron and Elpida memory cards are decent on Ethash as well as Equihash. Depends what clocks your card can handle and what algo you prefer (as well as what's most profitable atm).

Hynix sadly is bad at Ethash, so you better work your settings around Equihash algo. Find the highest stable core clock first then get to memory and power. Cards are not useless, they are quite decent just a bit limited in the choice of algo/coins.

My advice is also pay attention to the power draw and your temps as that's really important. 1-2 mh/s or a few sols are not worth it if your power is 20% more. Also the lower the power - the lower the temps. Less noise and longer life of the cards.


Note that I have a second rig - exactly the same. I can't get the power limit under 66-67% without my hash rate going to crap, but the memory clocks are stable at a bit higher clocks +910/+930. Cards are from the same batch, in fact all the 12 cards have consequent serial numbers. I guess not only cards matter but PSU, Mobo, risers as well. Don't try to copy settings from somebody else even if they have same hardware. Just play around with your settings for a couple of minutes/hours and find what's best for you.

If you are just getting into mining, don't be too picky on hardware. Just see what cards you can afford and find then build your rig around them. The sooner you start mining - the better. You really lose more while waiting than building a rig with a bit lower ROI. Also don't go with more than 8 GPUs if it's your first rig.

It has Hynix memory, try mining something else.

Yeah, I tried forcing constant voltage on my 1060s, changed the default volgate curve in AB also. It doesn't affect your memory stability in any way. It only affects the core clock in a smart way, you better don't play with voltages on nVidia GPUs, power limit does the job for you.

Let's say your GPU runs at 1500 Mhz core clock at stock (+0 core) and reduced power limit to 60%, that's at about 0.8mv. By increasing your core to +100 you don't force the GPU to draw more power, you only force it to run at 100 Mhz higher - 1600 at the same voltage and power draw. If your GPU runs 1400 stock then +100 will make it run at 1500 etc. You basically set some extra Mhz at the same voltage and power levels. Simply said you get the full potential of your GPU kind of free.

Some GPUs can handle +200 even 250 others can't take even +100. You should carefully play with your settings and see whats the maximum stable speed.

If you are concerned about electricity then work with the power limit as well and see how low you can get it without losing too much performance.

My 1060s run stable at 60% power, around 0.800mv, some of them run at 0.762 even. Losing about 1% hash rate compared to 100% power limit.

There is no magic in that basically the people prefer 1063 video cards. They are cheaper, and the speed of their mining is the same (no cents count). Accordingly, according to the calculation of the price-quality 1063 best, unless, of course, if you going to mine etherium, where later you will need a large amount of memory. Actually for mining this is the only advantage of video cards 1066 against 1063.

I have:

EVGA 1066 - Hynix - 20MH/s
ASUS 1066 - Micron - 23MH/s
EVGA 1066 - Samsung - 21.4MH/s

ASUS 1063 - Samsung - 25MH/s


Is Samsung mem in the 1060 cards only good in the 3GB models? I was pretty disappointed in the 6GB 1060 with Samsung mem cause I thought it would perform as well as the ASUS 3GB that also had Samsung. Both of them OC the same. 6GB Samsung Just gets poor hashrates.
