An Inside Look at Crypto Mining
Many people think of cryptocurrency as a virtual form of money stored in a digital wallet, but the process that generates these digital coins, called mining, is a quite extensive physical operation.
The Crypto Rig
In our latest project, we managed to get 12 GPUs (graphics processing units) up and running effectively. Over a duration of 48 hours, these gave us a very stable performance. One GPU needed a slight power upgrade due to occasional crashes, but with this, we have the rig running smoothly at an average hash rate of 162 to 164 mega hashes on Raven coin. This translates into approximately 13.5 mega hashes per card, a noteworthy performance for 4GB 470s.
Power Supply and Stability
However, the process was not without its challenges. We had to cope with power supply issues. Given the demand of the GPUs, we had installed three 900-watt power supplies for the processing units and risers. Additionally, a separate 650-watt EVGA was installed for the motherboard and peripherals.
The location of the mining operations was in an unfinished basement, sharing power circuits with equipment like the HVAC, fridge, hot water heater, gaming computer, adjustable desk, and lights. Thus, we had to balance the power load tactically between a 15-amp and a 20-amp circuit, running both 110 volts.
Power Audit and Solutions
In an effort to monitor and manage our electricity consumption efficiently, we used a voltage meter to bug the entire rig. The readings we got were around 1850 watts. This realization led to the decision to engage a professional electrician. The goal was to find a way to run an electrical cable from the garage to the basement, hence expanding the power supply reach.
Future Expansion Plans
In the short term, the role of the electrician is to ensure a dedicated and stable power supply for the 12-GPU rig. This constraint is what prevented us from extending beyond 12 GPUs, despite our rig having the capacity to accommodate up to 19 GPUs.
The long-term plan is to not only expand the GPU capacity as the power situation improves, but also to build an exclusive space for an advanced crypto mining set-up, complete with dedicated AC and exhaust ducts. In effect, we’re looking towards constructing a 4.5ft x 10ft dedicated mining room complete with a studio for streaming.
Continuous Mining Operations
In the meantime, we’re running a 12 GPU mining rig that is stable and delivering on the expected performance. A noteworthy mention here would be the utility of the offerings from Misfit Mining. The aesthetic and functional benefits of their products enabled us to order more for our future expansions.
Extended Mining Capabilities
Damage to some cards, however, is a visible obstacle to our plans. But we are looking for solutions, and have sent one for repair to Canada. If the repair goes well, we’ll have the others fixed as well. Once repaired, these cards will contribute to our GPU setup, taking us closer to our goal of 19 GPUs.
Keeping Up with the Mining Community
Keeping the community informed and updated about the progress of our mining operation is a key priority. Our analysis of the 12 GPU rig performance over a month will provide insights on what kind of yield one can expect from a similar set-up. Following the money trail – what does a 12 GPU mining rig running 12 470s deliver for Raven coin – will be an engaging exercise.
Overall, the endeavour to set up, run, and manage a mining rig is not a simple one. It requires planning, technical expertise, and a lot of power supply management! But the process and experience bring a lot of learning and insight into the world of cryptocurrency and the art of mining.
Sharing this journey as it develops enables us to engage with the broader community of hobbyist miners. Empowering them with knowledge, insights and tips to build and manage their own mining operations is a key objective. So stay tuned, subscribe, share your thoughts, and remember – happy mining!
