Exploring the Intricacies: A Comprehensive Mining Farm Tour

Building a 10 GPU, 400 Mega Hash Ethereum Mining Rig

The world of cryptocurrency is expanding, and with it, the demand for more powerful and efficient mining rigs. In today’s article, we will build a 10 GPU, 400 Mega Hash Ethereum mining rig, detailing each step of the process.

Parts for the Mining Rig

Firstly, let’s start with the parts rundown of our entire build. We are using a triple A wave 12 GPU frame, which gives us the flexibility to add more GPUs in the future if required. The frame we are using is the white one. For power supply, we have two 1000-watt EVGA ATX power supplies.

The motherboard for our rig is the E Sonic B-250. These motherboards are commonly purchased from Alibaba, directly from China. We are using an Intel standard stock heat sink and fan for our CPU, which in our case is the Intel Pentium G4400.

In terms of memory, this rig uses the Vengeance DDR4 3200 8 GB memory stick. We want to clarify that 8GB is not required and one can get by with 4GB without any issues.

For storage, we are using a 64 GB solid-state drive, along with eight GPU risers of 120mm LED fans, which are 38 CFM each. We also have ten new white GPU risers from gpuRisers.com, which come with the USB cable and with the PCI adapter card as well.

GPU Specification

The GPUs we used for the build are Zotac Gaming amp white 3060s, Zotac Trinity OC 3070 Ti, PNY RTX 3070, Twin Edge Zotac RTX 3070, Zotac 1660 Super, Tough Gaming 1660 Super, and an EVGA 1660 Super.

Assembly Process

The assembly process started by setting up the frame and installing the motherboard and power supplies. We continued by installing the CPU and memory, followed by the solid-state drive and the GPU risers.

To power the GPUs, we used six to six, plus two PCI cables. After all components were properly installed on the frame, we moved on to organizing the GPUs. The GPUs were then placed according to their sizes and power use, with the bigger ones at the top and the less power-hungry ones at the bottom.

Once everything was fixed into place, it was time to deal with the cabling. This process involved plugging in the PCI cables, the adapter cards, and the USB cables. The final step was to set up the Hive OS on the solid-state drive.

Overcoming Challenges

As with every project, there were challenges to overcome during the setup process. One of the most significant was the issue with running two ATX power supplies. After some thought, we realized that we needed to loop the 24-pin connector. Doing so enabled the power button on each ATX power supply to turn on simultaneously.

Once this issue was resolved, we successfully ran Hive OS on the rig, named it ‘Banshee’, and connected all ten GPUs. With all components working together seamlessly, the rig was delivering a whopping 400 Mega Hash, mining Ethereum.

Power Consumption and Profits

The rig was operating at 1270 watts, and with our cost of power at .058 per watt, the cost of power was about $1.77 per day. With an Ethereum price of $3814.93 at the time of writing, this gave us a daily profit of roughly $20.59 after deducting the cost of power.

Wrapping Up

In conclusion, while building this Ethereum mining rig was not a simple task and was time-consuming, it was a great learning experience. It provided a glimpse into the considerations needed when planning and executing such a project, from component selection to overcoming unexpected challenges. With a daily profit of $20.59, the rig has the potential to deliver substantial returns over time, making the effort worthwhile.
