What is a mining rig?

A mining rig or rig is a computer system used to mine cryptocurrencies. Basically it is a dedicated computer that has been acquired, assembled and operated specifically to undermine a certain cryptocurrency. The same is composed of one or more graphics cards connected to a motherboard in order to increase its rate of processing or hash hashrate .

While more graphics cards are operating, the greater the hashrate of mining, this is because the mining of ethereum is an operation performed exclusively by the GPU of your video card. Since the mining process is an exclusive task of the graphics card, the rest of the components such as the processor or ram memory go into the background. The important thing here are the GPUs.

The total hashrate of our mining rig will depend on the hash power of the graphics card, as well as the number of GPUs that are operating. The current standard is configurations with six or eight video cards connected to the same motherboard. This also implies that we will need a power supply with sufficient power (usually 1000 Watts or more) to provide power to our mining rig.

Basic requirements

  • One or more  NVIDIA GTX 1000 Series / AMD RX or AMD VEGA  GPUs with at least 4 GB of GDDR5 memory. Recommended graphics cards:  GTX 1070 8GB , RX 570 4GB ,  RX 580 8GB and RX VEGA 56 8GB.
  • An LGA 1150/1151 / AM4 motherboard  with enough PCI-E slots to support the number of cards to be installed. Recommended motherboards :  ASRock H81 PRO BTC R2.0  (LGA1150),  Gigabyte H110-D3A  (LGA1151)
  • If you use more than one GPU, you will need  PCI-E extender cables  for each additional GPU.
  • Power supply: You should check that your power source has enough connections to support the number of GPUs you are running and the total power enough to support the total power consumption of the system. (plus 20% extra power to avoid problems). For example, for a rig with  6 GTX 1070 GPUs  a power source like the  EVGA SuperNOVA 1200W P2 80+ PLATINUM is recommended.
  • A dual core processor compatible with LGA 1150/1151 / AM4 sockets; Recommended processors: Intel Pentium G4600  (LGA 1151), Intel Pentium G3260  (LGA 1150), AMD Ryzen 3 1200 (AM4).
  • At least  4GB of  DDR3 or DDR4 RAM . Recommended memory : HyperX FURY 4GB DDR3 (for 1150 motherboards),  Ballistix Sport LT 4GB DDR4 (for 1151 and AM4 motherboards).
  • A hard drive or SSD storage unit of 60 or 120 GB. Recommended SSD:  PNY CS900 120GB SSD
  • Operating system:  Windows 10 Creators Update 64-bits  or  Windows 10 Anniversary Update 64-bits  (these 2 versions of windows offer the highest rate of hash and are the most stable when mining ethereum)
  • A mining program, such as Claymore,  Genoil or Nicehash.

IMPORTANT  Before starting, make sure that your motherboard, processor and RAM are compatible. For example:

  • For motherboards with the LGA 1151 socket we must use Intel Skylake 6th generation processors and DDR4 RAM.
  • For the LGA 1150 motherboards we will have to use 4th generation Intel Haswell processors and DDR3 RAM memories.

1. Processor

We need a basic processor that allows us to run Windows 10, Ubuntu or EthOS, and is responsible for managing the rest of the devices in our rig. Here it is clear that the mining process is by GPU, which means that the workload will fall exclusively on the graphics cards. Therefore, when choosing a processor, a double core would suffice.

2. Base plate

The main feature we look for in a motherboard is the number of GPU slots it has, since this will determine how many graphics cards or GPUs can be attached, and therefore, its total hashing power. For example, 6 PCI Express slots mean they can fit 6 Radeon GTX 1060 cards with a hashrate of 20 MH / s each – or a combined total hashing power of 120 MH / s. Currently several manufacturers such as AsRock or Biostar have products specifically designed for the mining of cryptocurrencies (BTC Motherboard).

3. Graphic card

It’s time to choose the GPUs! There are several models of graphics cards recommended to mine Ethereum, but the most important thing to consider when choosing is the energy consumption / processing power / price ratio.

Hashrate: The ideal in this sense is to acquire a graphic card with a hashrate of between 20 to 30 TH / s. Currently GPUs that employ architectures such as Pascal (NVIDIA) and Polaris (AMD) are those that offer the highest mining hashrate.

Type of memory: your video card must have memory (VRAM) type GDDR5 to mine without problems.

Amount of graphic memory: the minimum essential for ethereum currently (July 2017) is 4 GB. However, due to the progressive increase in the size of the DAG file (which is loaded into the VRAM of your graphics card at the time of mining ethereum), it is advisable to choose a graphics card with 8 GB of memory.

We can quickly recommend the following graphics cards:

– Nvidia GTX 1070 and GTX 1080 Ti:  are powered by Nvidia’s Pascal architecture, have low power consumption and offer a high hashrate in Ethereum, Zcash and other cryptocurrencies. (30MH / s and 35MH / s respectively)
– AMD Radeon RX 480 and RX 580:  are based on the AMD Polaris architecture, have good performance and are easily optimized by updating the VBIOS (up to 30 MH / s)
– AMD Radeon RX 470 and RX 570:  are economic solutions based on the Polaris architecture and have almost the same performance as the RX 580 and RX 570. By means of a modification to the VBIOS they can reach a hashrate of 28 MH / s.
-AMD Radeon RX Vega 56 and Vega 64: based on AMD’s new VEGA architecture are high-performance cards that can achieve hashrates of up to 40 MH / s.

4. RAM memory

This is a fundamental component in any PC. Considering that the graphics card will do most of the work, we opted for the basics. In this case 4 GB of DDR3 or DDR4 (depending on your motherboard) should be sufficient for our mining rig. If you plan to install more than 4 graphics cards it is advisable to have at least 8 GB of memory (or properly configure the virtual memory of the system).

For a motherboard with LGA 1150 socket  , remember to use DDR3 1600 memories.

In the case of motherboards with socket LGA 1151 and AM4  you must choose memories of type DDR4 1866/2133/2400

  • Timmings: 2400MHz, 16-16-16, 1.2V

5. Power source or PSU

It is time to choose a suitable PSU for our mining Rig. This point is fundamental and basically what we are looking for is a power source with a high level of efficiency (80 Plus Gold). For example, if we want to assemble a mining rig with 6 GTX 1060 GPUs , we must bear in mind that each GPU has a maximum consumption of 120W (in normal conditions each will consume around 80W), if we multiply this figure by 6 and add the consumption of the other components (processor, motherboard, etc) will result in a consumption close to 800W. In this case, with a power source of 1000W 80 Plus Gold or Platinum we will have power to spare.

Here you can calculate the approximate consumption of your mining rig:  https://outervision.com/power-supply-calculator

Once the maximum consumption has been calculated, we can choose the source that best suits our needs. For example:

For a rig with 6 GTX 1060 GPUs we recommend the EVGA SuperNOVA 1000 GQ 80+ GOLD , of 1000W.

For a rig with 6 AMD RX 570 GPUs we  recommend the EVGA SuperNOVA 1200 P2 80 PLUS Platinum , of 1200W.

6. Storage unit

You need a storage unit to host the operating system and software for mining. The best option right now is to use a hard disk of solid type or SSD. An SSD is a solid state storage device as there are no moving or breaking parts, and it is also much faster than a traditional hard drive. If you are only going to mine Ethereum by being part of a pool or mining pool, then you will get a low capacity SSD.

7. Case

Finally we must choose a case for our mining rig. To mine with multiple GPUs connected to the motherboard, we are going to require a case of the open type ( open air case  or  mining rig case ) with enough space inside to house the different components that will integrate the rig. The choice of this component will depend on the number of GPUs to be used and your budget. If you have the necessary tools, you can even choose to manufacture it yourself. It is the best option and probably the most economical.

9. Additional components

We already have all the essential components to assemble our mining rig. As is logical, we will also require a monitor, keyboard and mouse . If you plan to build the frame by yourself, you will also need the respective ignition and reset cables . Likewise, our mining equipment must be connected to the router using 1 ethernet cable or wifi adapter.

Optionally, we can add the following components:

– Economical LED monitor Acer 21.5 “, to configure and monitor our rig
–  AmazonBasics keyboard and mouse
– Power button and reset
– Molex to PCIe converter cable , (8-Pin PCIe to 2x Molex)

– Adapter WiFi USB  TP-Link AC600
– Thermal paste MX 4, will help you reduce the temperature of the processor
– Pack of fancoolers ARCTIC F12 PWM 120mm, for adequate ventilation.


Optimal configuration (October 2017)

With the components we have selected we can start the task of assembling our mining equipment, for this we will include as an example two configurations based on AMD and Nvidia with the best price performance ratio:
