Two Days ago, I introduced the world to Vlad Zamrig, my ethereum mining rig. Well, at least it is mining ethereum for now, it may switch to Zcash or Monero in the future, especially given adjusted rewards for ETH blocks from 5 to 3 in the coming hard fork in two weeks.
I've had some trouble shooting issues with the rig over the past couple days regarding getting more than two GPUs running consistently. For a few hours I had 3 running, but one unexpectedly shut off. Another time I had three running and got greedy and tried to add a fourth, and since then have not been able to run more than two at once. I ordered some better powered risers and think this may fix my problems, but I'll do calculations off of two.
Rewards
I excitedly showed my girlfriend my rewards, and she read "point zero zero....all I see is a very small number". Owned
I tracked my rewards over 24 hours: at 7:56am yesterday, my total rewards were roughly .00101 ETH, now they are .00431 ETH. So in 24 hours I earned .0033 ETH, which equates to $0.96 in ETH mined over the last day.
Electricity costs
One kilo-watt an hour costs about $0.10. Between my motherboard, CPU, and two GPUs, and my attached USB slots, I am likely using between 250W and 400W of power. At 400W, I am breaking even after electricity. At 250W I am making about 1.5 cents an hour. A conservative guess is I'm using about 350W and making half a cent an hour.
GPUs are efficient though: each GPU added adds roughly 1.2 cents to electricity costs, but 1.6 cents to rewards. So my estimate is that when I get all four GPUs running with better risers, I will make about 1.3 cents an hour.
Hour: $0.013
Day: $0.312
Year: $113.88
At this rate, this rig will take about 15 years to pay off. ¯_(ツ)_/¯
That doesn't take into account the possibility of increasing value of ETH (or BTC that I trade it for), as well as knowledge gained about building a mining rig. But as of now, this current rig is not going to be adding to my net worth.
I'll probably add a few more blogs about mining adventures:
- Trouble shooting: it's easy to follow along with a guide or video, but unexpected errors can add hours or days to the process, and there is very little written about these online.
- How to build a better/more efficient rig than mine that earns more
- Switching from ETH to ZEC/XMR or other coins
- Actual profitability report when I see my electric bill
