This is how PCs are used only to mine cryptocurrencies

Below we are going to describe the different components that are part of a point-by-point mining RIG so that you can see how they differ from a computer or even a conventional server. Although you will see references to products in the following sections, this is so that you have an approximate idea of ​​how the configuration of this type of system is, the performance levels are requested in each of the sections and how they differ from the PC what we have at home.

motherboard and processor

The first point when assembling a system is the choice of motherboard and the mining boom has made it just like we have boards for workstations, conventional personal computers or servers, etc. We can also find models for mining RIGs, such as the following BioStar model that allows us to connect up to 12 different graphics cards through the 12 PCI Express slots that it includes. Of course, for this you will need to buy several Riser PCIe

And what about the CPU? We have not forgotten, but we are limited to the LGA1151 socket, which is why a good choice as a processor for our mining RIG is an i3-9100F.

RAM and storage

Our motherboard supports DDR4 memory and in total we can fill up to 32 GB of memory in the form of two slots of 16 GB each. In any case, the fastest RAM is not required and neither is the one with the most capacity, so with a DDR4-2400 it will be more than enough and in a configuration of two modules of 8 GB each.

And what about storage? Well, if what you are going to do is join a mining pool, a low-capacity SATA SSD will suffice, but with the following 500 GB SSD from Western Digital you will have more than enough:

Multiple power supplies

PSU RIG Mining

Energy efficiency is important in these systems, since the objective is to have the greatest amount of mining possible using the least consumption. So to begin with, what we are going to need is a power supply with a high level of efficiency and, therefore, with an 80 PLUS Gold certification or higher, here each watt is essential and it is not a plan to lose it. Furthermore, since there are a large number of graphics cards used in each RIG, you will find yourself needing to place not one, but several PSUs per mining RIG.

Our choice for power supply is the 80 PLUS Gold certified CORSAIR RM850X with 850W of power, which will allow you to seamlessly connect up to two graphics cards for seamless mining on each. Although there are 1000 and 1200 W models, these have a higher price that must then be recovered through cryptocurrency mining.

The Riser: essential in a mining RIG

PCI Express riser

The Riser are a series of expansion cards that allow us to connect several additional graphics cards on a motherboard and among other things allow us to transform PCI Express ports with fewer lines and designed for expansion cards other than graphics cards in ports of 16 lines. Which will allow us to connect several graphics cards to the same motherboard.

RIG Mining Graphics Cards

Put another way, it turns PCIe x1 or x4 ports into x16 connections, so you’re going to need at least one of these for every extra graphics card you’re going to install in your mining RIG, which makes each of these they are perpendicular and give them that particular configuration for which mining RIGs are known, which completely differentiates them from any other type of computer, since they do not use conventional PC cases due to the hardware layout.

The essential: the graphics card

Once we have all the pieces of our RIG for mining, we have to choose the graphics cards that will be used to mine. Here it is important to keep in mind that the choice of the graphics card has to do with the performance it has, mining at certain levels of consumption and in many cases you will have to touch some parameters of the graphics card.

We cannot forget that when mining it is not relevant to get the maximum possible power, but to relax the consumption of the GPU and for this, undervolting movements are usually carried out that, although they lower the maximum clock speed that can also be reached. it does so with consumption when reaching said speeds. The VRAM, on the other hand, is the opposite case and it is necessary to seek to maintain a high bandwidth within limits, so it flees from graphics cards with DDR memory or with 128-bit buses or less. In general, high-end graphics cards are the most appreciated when granting

Unfortunately, with a market where availability is so volatile, in many cases it is not possible to be able to buy enough units and without graphics cards that can undermine the rest of the system, it does not make sense. This is why large mining farms do not buy a few graphics cards, but several dozen and in extremely large orders. The usual thing is that the RIG for mining are not found in private homes, but in industrial buildings within areas in countries where energy is very cheap.
