12.6GH/s Ether Mining Farm
Hello everyone,
My friend and I have started building our 12.6gh/s mining farm. Right now we have 8 rigs with 6 GPU's each.
Current 8 test rig setup (6x Sapphire Nitro+ RX 580's (8gb) per rig)
Each rig is doing 180mhs to 188mhs. We have already bought all the parts for the next 62 rigs. I will update with a detailed walk through of our setup as we build it out.

How in the world are you finding GPUs to buy?
my only concern is the length of time his GPU will run at 30Mh
i can hear his cards crying from here
As for ROI - due to the quantity of cards we purchased, ROI will hit at about 10-11 months. We obtained a very good deal on the cards from a national distributor.
Concerning POS - we will mine whatever coins are profitable. Acquiring a larger amount of ETH before POS is our goal. Our calculations show very large profit margins for our farm. The small scale test has worked out great which is why we are expanding.
Each card is pulling between 100 - 130 watts out of the wall. We are paying $0.10 USD per kw.
The building we are running the farm in is already used by us for our other business - so there is no extra rent overhead. ROI is strictly cost of parts, electricity, and electrician labor to improve our power distribution.
Cidmo: Regarding life span of the cards. The ambient room temp is 20* Celsius. We have two large 30" fans (one to blow cold air over the cards, the other is an exhaust fan to move hot air out of the room). All the cards have had a vbios mod on the memory straps, memory clock increase, core clock decrease, and undervolt settings applied. They run at 58-68* Celsius.
Here are some smaller shipment of cards that have arrived. We are awaiting our pallet shipments which has the bulk remainder of the cards to achieve 12.6ghs
Will update more shortly!! Stay tuned!!
@Ericjh801 - I paid between $350 - $400 per card (depending on the type and manufacturer)
More to come soon!
Six of these cards are giving me around 190 mh/s or just over 31.6 mh/s per card. It fluctuates between 189-190.
However the difficulty has been rising!
At current difficulty you'll be able to mine around 380 ETH per year with 12.5 GH/s. You might have power outages or some rigs will require rebooting occasionally. Expect that number to come down. But let's use that number in our calcs.
Current price for ETH is $800. This may go up or down, nobody really know.
$800 x 380 = $304,000
You said you are at around 180-188 mh/s for six cards. So let's take the average of 184 / 6 = 30.66 mh/s per card.
For 12,500 mh/s you would need 407.6 or 408 cards or 68 rigs.
Edit: Just remembered you said you will have 70 rigs so that is 420 cards.
So let's assume you will have 12,877 mh/s with 420 cards. (30.66 mh/s per card). That will give you around 390 ETH per year at current difficulty. However as mentioned some rigs will have to be rebooted etc. so you will not get 390 ETH per year.
$800 x 390 = $312,000 = USD value of ETH mined per year based on current price
You spent around $350-$400 per card. Let's take average of $375.
$375 x 420 = $157,500 = GPU Hardware Cost
Based on my own experience six RX580 cards will draw around 900 watts at the wall by themselves. This is with gold rated power supplies. If you are using lesser quality the draw will be even more. Now you have to add in power draw for the CPU and RAM etc. I suspect you will be around 1000 watts per rig. Unless you are able to get the power draw down better than I have been able to. I am pushing slightly higher hash than you so maybe your are drawing less.
70 rigs x 1000 watts = 70,000 watts
You pay .10 USD per KW.
+/- $61,320 per year = Electrical Cost
Your motherboards go for around $154 on Amazon. Let's say you paid $130
$130 x 70 = $9,100 = Motherboard Cost
Looks like you are running Corsair HX1200 PSUs. You are running close to the limit with a power draw of 900-1000 watts. (unless your draw is less)
Nor sure how much you paid for the PSUs but I'll plug in $225.
$225 x 70 = $15,750 = PSU Hardware Cost
Decent Risers cost around $50 for six.
$50 x 70 = $3,500 = Risers Hardware Cost
Not sure what Pentium CPU you got but will assume $70 per unit.
$70 x 70 = $4,900 = CPU Hardware Cost
4GB RAM - decent brand will cost a little over $50.
$50 x 70 = $3,500 = RAM Hardware Cost
120 GB PNY SSD = $50 per unit ballpark
$50 x 70 = $3,500 = SSD Hardware Cost
Total Hardware Cost: $197,750 or close to $200,000
Total Electrical Cost: $61,320 per year
Total ETH mined in USD per year: $304,000
Profit: $304,000 - $197,750 - $61,320 = $44,930 in first year!
Ethereum's price will have to go up because difficulty is increasing. You might only mine 200 ETH per year as things are going or even less. It is by no means clear that you will ROI or make a profit.
I suspect a lot of people are going to quit mining ETH soon because of the difficulty rising and I do think the market will be flooded with GPUs sooner than later.
@asusrig - Also, we will be holding all of our ETH coins until the end of the year, paying out of pocket for the electricity, etc. We believe Ether will be far more valuable later this year which could double of potential profits. When ETH hits $1200 - $2000 per coin, our profit margin will be far greater than the calculations you provided.
We also have 94 AntMiner L3+'s coming in. We are in the process of acquiring a large sum of investment funds (5-6 million USD) to expand our mining operation. The electrical company is drafting plans to run 3 more 3 phase 480v lines to our building from the transformer. This will give us around 6,000 amps total (plenty of power to run as many machines as we can buy).
I also planned on holding my mined ETH and can pay for electrical and hardware out of pocket. However with the recent price correction it made me question that strategy. A few weeks ago I would have said the price of ETH was going to the moon! And maybe it will. But you just don't know and we are not done yet with FUD coming from the banks and governments. Seems like the crypo market really gets spooked as soon as negative news comes out from either banks or governments.
I am very confident that the price will bounce back. At the scale we are mining, holding coins for the POS system will be worth it.
We just received another pallet of 200 video cards - I will post pictures of the build soon!

I read that Ethereum founder Vitalik Buterin has thrown around a guesstimate of needing approximately 1,000 ETH to be one of the network's inaugural stakers. With 12.6 GH/s you'll probably mine less than 300 ETH in a year considering the difficulty increase the past 2 months. Not sure how much ETH you have accumulated already via mining and investments but someone starting out now with only a few ETH would need quite a bit of hashing power to accumulate at least 1000 ETH in a year.
In November 2017 you could mine over 1 ETH per week with 1.3 GH/s and now that is down to .76 or even .75.
I am switching my Nvidia cards to ZEC mining right now. I mined it a few months ago and it seemed a little more profitable than ETH. I probably should have kept mining it but tried my luck on ethpool.org which was a mistake and cost me 2 ETH. The ZEC / ETH Exchange rate seems to hover at around 2:1 but is was down to 1.6:1 a few weeks ago when ZEC's price was over $800.
Thanks for posting.
I've been tasked with doing a proof of concept. We started with one 6 GPU rig and are not looking to see where we can get GPU cards in bulk for additional rigs. Our model is similar to yours in that we extra space in our current building.

0.10/kwh is not bad. antminer is darkside , dont give them your dollar ... but if you need l3+ blissz modded frimware , tell me , isend me pm ont bitcointalk -> cryptonitro
best hs/w , and lower noise .. and no 100% fans anymore , devfee = 1,5%
have a look Here
hashking , very happy for you to can found so much gpu in this time. search for modded firmware for l3+ i got it if need but bitmain is veryu bad , and i wont send them 1 ct more . i would really love to have so much invest ... cause i m going to change country to develop slowly farm for average of 0.07 €/kwh. cryptoworld is a passion , and please have some machine for ELLA the only real pure coin at this time !
REGARDs
There is an inherent risk with this type of project - but the payout will be well worth it. I also find mining to be much safer than buying penny coins/ICO's. I know what the returns are versus guessing on a coin and having to day trade etc.
The best time to start mining was yesterday, the next best time to start mining is today.
Congrats, beautiful build.
If you want to flop all those into a server rack let me know 8GPU.com , as long as you have cool room temps and exhaust heat its much cleaner and better on cards to have in 4U cases. I build parts for this at 8gpu.com Then you add a rack for $150 and you can have 1.4GHS in a small 2x2ft area. 2.8GHS in the 2x4ft. Just looks sexy too rather then air cooled with warm temps in room.
Building out the next 15 rigs.
3 motherboards per shelf
More coming soon!
Have you considered running ubuntu with 13 cards?
If you have, why did you stick with windows?
