I'm just a small-time guy working a normal job as a physician assistant. My passion is building PCs and testing/reviewing PC hardware.
Hello everyone. Will here and today, I am going to be sharing a little project I decided to start back in early January. It is something that I had done some research on for a couple of months before finally taking the leap to do it and that is cryptocurrency mining. I would have had this article together and up sooner but I have been away for the last 2 weeks doing training as I am in the Army. So, when Uncle Sam tells me to do something, I do it. It wasn’t all bad though, being a physician assistant has its perks. At any rate, let’s see what I put into this single-card mining rig.
Intel Celeron G3900 Processor
First up in this build is the processor. For this mining rig, I chose the Intel Celeron G3900 processor. The Intel Celeron G3900 is a relatively cheap processor which is why it is perfect for a mining rig. The reason it is perfect is for the fact that a mining rig doesn’t require a very powerful CPU because the GPU basically does the heavy lifting. The Intel Celeron G3900 is a dual core processor without hyperthreading and fits into the LGA1151 socket. The processor operates at a locked 2.8GHz on the 14nm lithography with 2MB of L3 cache and operates at 51 watts TDP. The processor comes with an included cooler plus Intel HD Graphics 510 integrated and supports up to 64GB of RAM. I was able to obtain this processor brand new on eBay Marketplace for just $60.50, which is a little expensive as you can purchase this same processor for around $50 today.
ASUS H110M-E Motherboard
The next component was the motherboard. For this mining rig, I chose the ASUS H110M-E/M.2 motherboard. This is a microATX motherboard with the LGA1151 socket. The board comes with 2 memory slots that support up to 32GB of DDR4 RAM at 2133MHz. There are 4 SATAIII ports. For mining purposes, there is a single PCIe-16x slot and 2 PCIe-1x slots for support of up to 3 GPUs when using riser cards. The board does support M.2 but that would be overkill for a mining rig. I purchased this motherboard for just $44.43 on Amazon.
Crucial Ballistix Sport LT 2400MHz DDR4 RAM 4GB Module
The next component was the RAM. For this rig, I chose the Crucial Ballistix Sport LT 4GB RAM module at 2400MHz. This may be a bit of overkill for this system but this RAM was actually cheaper than the less aesthetically pleasing standard RAM modules at the time. I paid $52.99 for this RAM and feel that with the current market for RAM, I got a pretty good deal.
Pny 120gb Ssd
For my operating system and storage, I chose the PNY 120GB SSD which I picked up for $49.99 at my local Best Buy. This wasn’t a bad deal as this would only be used for Windows 10 and the various few programs I need for overclocking the GPU and for the mining itself. The rig boots up super fast for when I was making adjustments to the system.
MSI Radeon RX 580 Armor OC 8GB Graphics Card (GPU)
For the heavy lifter of this system, I went with an AMD card as they are still the best and most efficient graphics cards for mining cryptocurrency. As I was looking at graphics cards and the current market, I felt really stupid that I sold the RX 570 card I had purchased during the Black Friday deals as this card was nearly two times the amount of the RX 570. I purchased the most inexpensive RX 580 I could find that had 8GB of video memory. I purchased the MSI RX 580 Armor OC 8GB card from Newegg for $445 shipped. The MSI RX 580 Armor OC operates on a core clock of 1.26GHz with a boost clock of 1.37GHz and operates on a TDP of 185 watts.

Corsair CX650M 650 watt 80+ Bronze Certified Semi-Modular Power Supply
Finally, powering this system is a Corsair CX650M 80+ Bronze Certified semi-modular power supply. Corsair makes good, reliable products so for $57.99 shipped, this is a no brainer. This entire mining rig was placed into an old DeepCool Tesseract case that I repurposed. I will add custom railing for the GPUs and risers as I purchase them. The plan at this time is to pay off a card and then purchase another card for a total of 3 mining cards, all RX 580 8GB variants. If the profitability remains, I will continue to upgrade cards as more powerful and efficient cards become available.
I have a custom BIOS I am using with this card and have adjusted the core clock to 1117MHz and a memory clock maxed out at 2250MHz. The power limit is set at -15, temp limit at 75C and a fan speed of 70%; all adjusted via MSI Afterburner. These settings along with the BIOS mod nets 30.3Mh/s. With this speed and my 26.6Mh/s I get on my gaming PC that I mine on when not gaming, I get a 0.05 Ethereum payout about every 9 days which equals roughly $55 per payout at the current Ethereum to USD exchange rate; roughly $165 per month mining. If you factor in power consumption, which is only around 120 watts TDP and calculate cost of power, this system, along with the minor mining with my gaming PC, the total profit in a month is around $130; I have cheap power in Tennessee.

Conclusion and Final Thoughts
So, there you have it. This is my single card mining rig that I put together recently. I have been running this system for just under a month and have accumulated around $110 USD from mining Ethereum. At that rate, I will have the entire $712 system paid off in roughly 7 months, which is a decent return on investment. As I add new cards or other components, I will bring you folks an update and I plan to update at least monthly on the results of the mining. Thanks for stopping by and I hope to see you again.

Mining was no longer profitable given the electricity costs I incurred while living in Korea. I may revisit mining again in the future
Boya on July 29, 2019:
Why did you stop mining with that good profit? Or did the profit drop to much?

Thanks for your answers.

Thanks for your questions. Let me start my reply saying that I no linger mine. When I did mine, these were the monthly results I would get. Im not sure what Nicehash calculates nire whattomine.com. As you can see in the article, I used a custom mining BIOS on the card and mined what was the most profitable for AMD cards at the time. Thanks again for the questions.
mohkh on June 18, 2019:
Thanks Bro for sharing your experience.
Sorry about my English
I have questions.
When I use Nicehash profitability calculator and whattomine to check profitability for AMD RX 580 the profit around 13.5$ per month. but In your review you wrote profit 165$ per month.
What do you do to get this profit?
Are there any extra settings?
Are you still mining?
And how much you earn now?
please reply as soon as possible because I want to invest in mining using RX 580 cards.
