ETH Mining

So, you want to start mining Ethereum.

But you don’t know how to build an Ethereum mining rig?

Today we are going to use the best Ethereum mining hardware to assemble our mining rig. As we are going to build 6 GPU mining rigs, we will use 6 Graphics Cards.

As more and more graphics cards are going out of stock, we have to buy the correct graphics card. We don’t want to end up mining Ethereum at very low hash rates.

As many people have started mining cryptocurrencies – Ethereum is one of the most popular for mining. But, why are people investing so much in mining Ethereum?

Ethereum is the cryptocurrency that is ASIC resistant; i.e., you cannot mine it with any ASIC. You will have to mine it with graphics cards. I have also inserted Amazon links as it may help you buy them.

If you are really not into mining, then you can have a look into – Cryptocurrency Investment.

Price
$ 3,484.60

Update – Ethereum is trading higher than $1000. Soon it could be worth $2000, that’s 2x in profit.

Best Graphics Cards For Mining Ethereum

This is often asked as a question, right – Which are the best graphics cards for mining Ethereum?

But here is a question – which graphics cards should I use? Well, until today, I have used Nvidia GTX 1070 – Why??? Because of 2 reasons –

  1. They are good at mining Zcash.
  2. They also produce a good hashrate of 31 MH/s by a single card.

Even though you can easily resell these cards in the future at a great price.

Here is a graph that can explain to you –

GPU Mhs comparison

You can see that GTX 1070 stands out in MH/s. I have been using GTX 1070 to date without any problem. One GTX 1070 consumes 150W of power.

So, GTX 1070 is the best ethereum mining card we will use in this mining build.

6 GPU Ethereum Mining Rig Build

Our ETH mining rig will consist of –

Every hardware is listed below. Also, I have done my part of explaining every hardware. You will not have any problem assembling them.

1. EVGA GeForce GTX 1070 FTW GAMING

You will need 6 of them.

EVGA GeForce GTX 1070

As we are assembling 6 GPU ETH mining rigs, you will need 6 of them. If you are low on budget, you can always start with 4 of them and periodically increase them. GTX 1070 uses 150W of power, which is also great.

Each Graphics Cards will output – 32 Mh/s. So with 6 of them, you will have – 32 x 6 =  192 Mh/s.

Also, if you go with GTX 1070 for mining Zcash, you will get – 450 Sol/s. i.e., if you think you could not mine Ethereum at one point, you can periodically shift.

This particular EVGA Geforce GTX 1070 comes with 8GB GDDR5 memory and has two fans to keep the graphics card cool.

To maintain all the costs, we are going with GTX 1070.

Update – Most of the time, you could not find GTX 1070. You will have to go with GTX 1070ti, the latest version, and it is better than GTX 1070.

Update #2. Please use AMD RX 580 GPU as it now costs lower and generates the same amount of Ethereum Hashrate. (JAN, 2021).

RX 580

AMD RX 580 Prices have been discounted so you can grab them instead of GTX 1070 Ti. If you consider GTX 1070 VS AMD RX 580 then AMD RX 580 is better at mining Ethereum as it costs much lower than GTX 1070.

2. MSI Z390-A PRO

MSI Z390-A PRO

We will need a motherboard, right. So, we have to choose a motherboard that can support 6 GPU.

Absolutely, so we are going with MSI Pro Series Intel Z390 DDR4. This motherboard supports 6 GPU, and you can attach the GPU via RISERS.

This motherboard supports DDR4 RAM and is good to go with Intel Processor with LGA 1151 socket.

The motherboard is the base of your mining rig. Everything that you are going to build depends upon your motherboard. This motherboard will run 6 GPU that you will attach to no problems.

3. PCI-E 16x to 1x Risers

RISERSYou need to attach your GTX 1070 Graphics card, right. But how do you do that?

You can attach all your GPU via RISERS i.t PCIe 16x to 1x. These are small cables – where at the one end GPU is attached, and the other end goes to the motherboard.

You need 6 of them as we will attach 6 GPU. You can find Risers at a low cost – Make sure you buy them with other hardware components. Could you not buy them singly?

4. Corsair DDR4 RAM

Corsair DDR4 RAM

 

The MSI Pro Series Intel Z270 DDR4 support DDR4 RAM. We are going with 4GB RAM because the RAM never plays a role in your mining efficiency.

If you add 8GB RAM, the output would be the same as 4GB. So, I think you don’t want to waste your money on building this mining rig.

So, let’s go with DDR4 4GB rather than any higher RAM.

5. Intel i3 Processor

i3 processor

 

You will obviously be asking about the processor. i3 the processor that I recommend you to buy. Your processor supports Intel 8th & 9th Gen Processor.

You might be wondering, why not go with a better processor like i7?

Ethereum mining is a process where you mine with the GPU & CPU. That is exactly why it is called GPU mining and not CPU mining. You could mine with your CPU, but it definitely isn’t profitable.

We only need our processor to run the software, and the rest of the mining process will be carried by the Graphics Cards.

i3 is a good processor. We are using i3 8th, Gen, as this fits in our mining motherboard, which has LGA 1151 socket.

6. SanDisk SSD PLUS 120GB 

SSDEver since I’m building new cryptocurrency mining rigs, I’m including SSD rather than HDD. SSD is fast, and by using SSD, I would increase the transfer speed and decrease the time. Also, other things that I think about SSD are – They use less power consuming, and also, if you are starting up your mining rig, the boot time is reduced, and soon you will be mining.

I would also recommend you buy an SSD as it is just a little bit expensive than HDD. As the blockchain size of the Ethereum. The only things that will be going on the SSD will be OS, Drivers & mining software.

7. Corsair HX 1200W PSU

Corsair HX 1200 PSU

It is often hard to select the required PSU. Some of you might select a PSU that is way less than the required power supply. When you select the Power Supply Unit for the mining rig, you will only use 80% of the total that can be supplied by the PSU.

E.g., If you require about 1000W of power, you will not buy 1000W PSU. You will buy a 1200W PSU.

By doing so, you will be on the safer side.

So, let’s calculate our required power supply –

1 GPU consumes = 150W of Power; So, 6 GPU consumes -6 X 150 = 900 W of power.

Additionally – 200 W of power might be consumed by the motherboard, CPU, SSD, etc.

So, using 1200W PSU will be okay.

8. ATX Power switch

Power SwitchSo, how are you going to power on this mining rig? This ain’t using any ATX cabin, and there isn’t any button to start. To be sure, we have to buy ATX Power Switch.

ATX Power Switch is a wire that will attach to the motherboard, and another end of the wire acts as a button to start and turn off the rig.

This is one of the smallest components, but you must not miss this one. It is effortless to attach.

Whenever you buy this – Buy it with other components, too, cutting out the extra costs.

9. Mining Rig Open Air Frame

Open rig caseYou will need an open mining frame that allows good airflow. Make sure that your mining rig frame is not conjusted.

I would recommend you build your cryptocurrency mining frame. In this way, you can build it the way you want. The only essential things would be few aluminum rods and some hardware skills.

Make sure that everything will fit properly.

Now there will be enough space for the GPU, Motherboard, SSD, PSU, etc.

This mining rig frame will help you out –Mining Rig Open Air Frame if you want to pick one up.

10. OS

Choosing your operating system, for now, might not be hard. If you are familiar with Windows, then you can use Windows for mining. Linux is even good as you will cut out the costs.

But especially if you are going to use this mining rig for mining Ethereum, you can go with ETHOS.

11. Mining Pool

It is also important which mining software and pool you use. I would recommend you using Claymore Dual Ethereum Miner as software.

And for the pool from the last few months, I have been using eth.2miners.com.

I received regular payments of ETH, and they have low fees in comparison to other pools.

Conclusion

With this particular Ethereum Mining Rig, you can mine about $379 of Ethereum every month, and this is probably good.

But, here is a good trick that keeps me going – When I mine Ethereum, I do not sell it immediately; I wait till the prices of Ethereum have gone up. In this way, my return on investment is met very early.

But, always remember that you do not lose money when you invest in a mining rig; instead, you earn money.

But, How??

The thing is, when you buy a mining rig, you can mine as much as you can. But when the time comes when you don’t want to mine, you can always resell, and hundreds will buy your rig.

Graphics cards can be resold.

if you are a trader, do not use yobit.net.. they are a complete scam and thief’s that support pump and dump. tech support will not respond to anyone unless you pay in coins. they are a problem to the crypto trading industry. only Russian users get help. the Russian users come together and scam all other foreign users. stay away from this sight

I purchased 6 1070 FTW edition GPUs and they have two 8-pin power connectors each. Do I need to get more powers supplies to accommodate the extra 8-pin slot? Also, should I have connector branch from the power supply to both 8-pin slots or give each slot on the GPU its own connector to the power supply?

Hello, I was wondering if you could help me with a bios modification question. I have a rig running mostly rx470 mining editions, are these cards already maxed out when it comes to tweeking their bios? Im asking becuase i have tryed to tweek them in the past and run into issues and a loss in hash rate…

Hello,

Great article but I still have a question.

Can you show the difference in ZCash mining between a RX 570 8Gb and the GTX 1070.

With Ethereum the difference is 2.6 Mh/s.

How much is the difference in Sol (ZCash) between the GTX 1070 and the RX 570 ?

Is there a difference in speed with 4gb or 8gb Ram on the Cards?

Thanks in advance!

I am in the peocess of ordering parts for a good 6 card mining rig. What is the best GPU card i can get now that uses the least amount of power? What is your email? Maybe you could send me an updated list for 2018? Or are all the parts still basically the same as your first list? Thank you so much for all this help!!! 🙂
Also, are there mobos out there that are capable of more than 6 gpu? Or do you just connect 2 mobos together to get more than 6 slots? Thx

Hi

Very detail write up.

I got a qns and i still not sure about the correct way of connecting the riser

So 6 riser which should i buy molex, sata, 6pins or riser with all the 3 types connector.

Been reading and seem like the 6 pins is the best. But psu only have 6 pcie connectors so can i use those splitter 6pins to 2 pcie connector?

Any advise? Quite lost.

You do have some great information on mining with the GTX 1070, thank you. But you don’t mention the 1070 Ti, how come? According to other research I have found that the 1070 Ti is actually more efficient, and faster than the 1070 so overall it can cost less and mine more.

Hey,
Great article. I really appreciate what you shared and the discussion down below. Two questions for you:
1. Based on the stores that you usually buy GPU (if you could add international info will be awesome) do you think it is reasonable to invest in the rigs or should you hodl your finances and wait for a price drop? I know it is speculative kind of a question and things change every second but I am just qurious about your opinion.
2. What PSU valtage do you recoment since both the logic that you used with the 20% rule and this calculator by OuterVision (https://outervision.com/power-supply-calculator) (the same as the CoolerMaster one) is suggesting that you buy “bigger” PSU? (GPUs use a variable of 150, meaning around 1000 and then adding the processor and the 20% rule getting us at 1600W PSU or 2x650W PSUs) And since we are the the PSU topic – what brands do you recommend and do you recommend getting 2 PSU in the first place?
Thanks for the great article and the discussion below I am most grateful for your work and passion!
Regards,
Dobromir

If you are mining ETH have in mind that the 3GB cards (inclueding GTX 1060) are getting obsolete as we speak – here is my source of info (https://investoon.com/tools/dag_size).

So, I installed all the GPUs individually and updated the drivers as i went.
All cards are recognised now. I still haven’t got mining yet as the Claymore mining tool keeps crashing as soon as I go to start.
I have placed several different drivers on the GPUs but still no luck.

Soham,

This rig costs $3500 for 192 Mh/s. Wouldn’t it be more economical to buy something like a Goldshell Mini Doge for $1200 at 184 Mh/s?

I am trying to figure this out myself now so any thoughts you have would be appreciated.
