I'm new to all this, so go easy with me. I searched a little bit and ended up making the decision of mining using 6 GPUs (Nvidia GTX 1070). The electricity cost in my country is like 0.05$/kw (If not lower) and planning to go with Ethereum.

1. Should I switch to another crypto currency?
2. What should I understand before starting to mine
3. I'm going to follow this (http://www.coinminingrigs.com/how-to-build-a-6-gpu-mining-rig/). How bad/good are the instructions and information's there?
4. Solo or pools mining?
5. How much hash power I'm going to generate? 180 Mh/s?
6. Is this  (https://www.cryptocompare.com/mining/calculator/eth?HashingPower=180&HashingUnit=MH%2Fs&PowerConsumption=1000&CostPerkWh=0.05)accurate?

to start use NiceHash.
this is ideal for beginners.

Eth is probably not the best currency to mine nowadays, you should check out zcash, lbry or hush. I skimmed through the article, the instructions seem fine, just install windows directly, i don't see any reason to install ethos first. Also you're probably going to get 180 with a little overclocking maybe even more but that calculator is a bit off, use other calculators and average them out. Pools are definitely the way to go

can GTX 1070 mining dash?

It can mine Dash(x11 algo) but its not going to be profitable  to mine with  graphics cards. If you want to mine dash you need to go for asic miner you can get x11 asic miners from bitmain , ibelink,innosilicon  and baikal .

I suggest you check whattomine.com first, right now the most profitable coin to mine for 1070s is equihash and also do a little research on every coin you mine make sure you believe that these coin will go skyrocket else you can just mine to nicehash and liquidate it to BTC > local currency for faster roi

Yep, and he see Ethereum mining on 1060 or AMD card.
1070 - zec or lbry

 DASH hasn't been GPU mineable for a profit for a year or so, since shortly after Pinidea IBelink and Baikal started selling ASIC miners for X11 last spring.

 ETH on the 1070 - varies, but the last few weeks it's usually been inferior to ZEC among others on profitability.

 Nicehash is usually somewhere near but not AT the top on those cards.

I have two rigs identical to what you are building - same cards. I built them both in the last week. I am seeing 183 MH.

I would not fool with windows. Use nvOC. It is free and there is a thread about it in this forum. I am a newbie to this and it was easy to setup. You don't even need a hard drive it runs off of a USB thumb drive. I downloaded the v19, entered my BTC address and was up and running in no time.

NvOc is great, if all your cards are the EXACT same ;p  in my situation i have all sorts as quantity limits put me in that position, SO:
I can't use NvOc as it dosent have individual OC settings per card (last i checked)

@OP read this board (mining:altcoins) , honestly like ALL your questions are answered in the first 5 pages of threads :)
Solo mining requires alot of hash, 1070's are good for many algos, LBRY, equihash, Nist5 lately looks profitable, watch Neoscrypt for rises in profits too sometimes
ya about 170mh/s eth or so, but really, unless your speculating, Nvidia has more profitable algos usually
Good Luck! Welcome to the legal.money.printer revolution :D

NVidia GTX1070 can mine every cryptocurrencies : only AMD GPUs cannot mine some.

For really new beginners, you can use Minergate.
After Minergate, Nicehash is better but more complex : it is still a lot easy than direct mining.
If you have time to learn, you can use specifics mining softwares : CCMiner TPruvo, Claymore's dual miner...

does the internet speed affect to mining?

Lol what is this bullshit? Unless there's some new coin called CUDAcoin that only allows Nvidia gpus to mine on the chain, all AMD GPUs can mine the same algos that Nvidia GPUs can mine on. The only real difference is efficiency and hashpower. The 1070 can mine dash but X11 ASICs far outperform them. Nicehash is your best bet for the most profit as it switches algos for maximum profit with a small fee.

It is by far easier if they are all the same but you can manually configure them.

this one will give some ideas how much gain you will going to get when you start from the start and after that you will be able to find more profitable coins
I think nicehash is the very useful tools for us who just wanted to run our rig without doing any difficult codes but time will give us more ideas so good luck.

 Any currency that can be mined by the GTX 1070 can also be mined by AMD GPUs - the question is "which is more efficient".

 AMD wins some easily, NVidia wins some others easily, a few are very close depending on the specific card model and sometimes even on the specific settings each card can handle reliably.


 Speed of internet isn't a significant factor in cryptocoin mining - RELABILITY is a major factor, and lag is a minor one.

My miner with six cards has been on 2 days and 18 hours. During that time it received 51.9mb and sent 55.8 mb. The volume of data is not large but it needs to be a steady connection as the computer is constantly communicating with the servers to get new data to crunch and send back the results.

i have only 2 1070's right now, overclocked i get about 31-32mh/s for eth each. As of the moment I prefer to watch what to mine, mine that sell it for BTC then buy whatever I want...

for example, eth estimated profit for me is around $2.83 at the moment per day, the top mining coin is around $4.40. Mine the most profitable you can sell it for eth anyways. Just make sure you keep up to date as the most profitabes fluctuate a lot. I think there is a mining pool that auto sells to btc?

Yes nicehash selects the best paying coin and mines that and pays you in BTC. Lots of fees though. If you are the type that is checking and adjusting daily you could do better choosing coins yourself but if you just want to set it and forget it nicehash isn't a bad choice. My son runs it in his gaming computer with two 1070's. On my dedicated mining rigs I jump around manually.

It is not true. Xevan algo doesn't exist for nvidia yet.

What are your overclock settings set to and how stable is mining? 

 I've never used nvOC, but that's because I had an already-working setup I could clone before I heard of it.
 It's a Ubuntu-based LINUX distribution, so it should have standard (VERY GOOD) LINUX reliability once you get it configured and working.

By the end of this week, I will have 4 new ASUS ROG Strix GeForce GTX 1070. I will try nvOC to see how it works.

1) Probably. ETH has almost NEVER been the best option for a 1070 over the last month and change.
3) Don't skimp on the power supply, a 1000 is marginal AT BEST for 6 of those 1070 models (I have a few of those specific cards, good cards but their TDP is 180 watts).
    I'd STRONGLY recommend going to AT LEAST a Seasonic X-1250 or EVGA G2 1300 and even THOSE are going to limit how hard you can push the GPUs.
    You might want to STRONGLY consider going to a 2 power supply option.
4) Unless you mine something with a VERY small total network hashrate, go pool for reliable income.
5) On ETH with those cards, probably around 180-185 IF you have enough power to feed them.
    If you have to turn them down far enough to SURVIVE on a 1000, more like 160.
6) all calculators are snapshots of CURRENT conditions, I prefer whattomine because they'll look at the "last 24 hour average" which is a lot more accurate than a one-shot snapshot.
     Keep in mind though that conditions CHANGE, so even an ACCURATE estimate will be off tomorrow as price changes, difficulty changes, etc.


 You do have a low electric rate, which should help your long-term profitability a LOT.

I have 12 1070 cards (two 6 card systems) running 100% stable with a 100 watt power limit on each card and am getting 183 MH/sec per six on ETH and 2500 Sol/sec on ZEC.

I agree a good power supply is a must particularly get one platinum rated so it is more efficient but I think most people with 1070's have them set at 110 watts or less which with 6 cards is only 660 watts plus whatever the rest of the system takes. I use Corsair 1200 watt power supplies and no issues.

From my testing upping the power over 100 watts gives very little gain in hash rate. I certainly wouldn't want to go from 100 watts to 180 to gain 2 MH/sec.

I agree with that. I run the cards when they are most efficient and last long.
