So this turned into a hardware discussion about 1070 rigs, which is pointless.

The question was What to mine, right? Right now, for a safe bet - download the latest KlausT version of CCminer (version 8.19 x64 cuda 9.1) and use it to mine neoscrypt at nicehash. I find that even when whattomine.com says equihash for nicehash - this KlausT miner is so good at neoscrypt that you do better.

So that also leads me to suggest you look at one of the various neoscrypt based coins around right now. If you want to mine something and hold it for the long term hoping you will get something that will go to the moon like bitcoin did last year, I personally recommend mining whatever whattomine.com suggests as the best neoscrypt based coin using the miner I suggested above, BUT as long as it's a coin you can deposit to a well known exchange like Bittrex - then sell it and buy ETH  (or some of the better ETH based tokens like EOS, Omisego, enjincoin, etc) or maybe buy Stellar Lumens. ETH is going to go the way of bitcoin because it is the infrastructure of so many new things. There is just no point directly mining ETH anymore but if you mine something currently profitable you can just buy ETH with what you make. ETH is what bitcoin should have been.

Or you can just do like I said and mine neoscrypt or equihash on nicehash and get the BTC then use the BTC to buy whatever or cash it out.

No one can tell you what is the best thing to mine because it changes every day. You have to learn to watch what is profitable and change your mining habits accordingly.

I'm not going to tell you how to get the KlausT ccminer, or how to use it, or how to mine to nicehash, or how to work out what is most profitable because that is all stuff you have to learn yourself by doing a lot of research and experimenting. There is a really great website called "Google" where you can search stuff and find it out for yourself. You can also do a lot of researching on these forums to learn a lot, but you have to know that 70% of what you read here is bullshit, or it's people trying to take advantage of you or scam you. I think about 85% of coins out there are totally useless, or scams. You have to learn which ones actually have real application, are not just clones of other coins/concepts or are just pure scams.

This is all part of the fun of mining and learning. I have been doing it for 2 years. If I hadn't been naive I would now hold $200,000 worth of ETH because I was mining ETH when 200mh/s was enough to make 5 ETH every 2 or 3 days. I sold most of the approximately 200 ETH I mined when it was at about $50-60. I believe ETH will be worth at least $5000 each in the next 12-18 months.

Like someone else said - there are very profitable coins out there but people like me who know about them won't post about them on public forums because then all the noobs will start mining them and destroy their difficulty. You have to learn to find this stuff out yourself.

This isn't just directed at the OP - it's directed at all the people who have just built their first mining rig and they post "what should I mine". There is no answer to that that someone will just tell you - it's up to you to learn, experiment, fail, succeed and have fun ON YOUR OWN USING YOUR OWN BRAIN.

So, the vertical cards are cooler than the other. Is it caused by vertical position? or 1,0,7,8,9,6,10,11 too close (correlated with cards airflow), so the temps higher than the vertical cards.

Windows has limited max 8 GPUs on the system, and Linux (13 maybe). But with a few trick, we can add more than 8 GPUs on Windows.


People out there even try so hard to set up 10-13 GPUs. And stability issue will be the main problems for broke the limit.

This forum is main sources all of the info, so keep watching here.


which GPUs at under 50 degrees?

167.75 W  seems to be a very high consume for a 1070

Heat must be horrendous between those cards no?

I space my cards on 3 levels, they are spaced well apart.

Oh yeah, since you are using full-time AC, it's no big deal. About a profitability, you need to know the best Algo for your Cards, sometimes you need to speculate on new coins. Keep open your eyes and keep watching any newest info.

Nice rig you have. Seems like professional work. Build your own?
Problem is most users won't share the most profitable coin (because if they do, you'll start mining it, then some others and difficulty will rise lowering their profits ) ... best coin is always search your own

have you tried https://whattomine.com  also you can use some autoswitching pool like https://miningpoolhub.com

If I right, Gigabyte GTX 1070 airflow will push hot air to up-sides and down-sides (if you put your GPUs on horizontal).IMO, It will be heating problems if you put your GPUs below the other GPUs.

Same here - I get 2.15 mh/s on gtx 970 and 2.8 on gtx 1070 slightly oc both. Which ccminer are you using???

My farms are issued to the ccminer:
1050 1282 kH/s
1060 2249 kH/s
1070 3620 kH/s
The overclocking of cards practically does not affect the speed.
