The KraKen Triple miner is my latest build where I try to get the most out of the mining rig by using a more expensive CPU i7 7700 to mine Electroneum ETN or Monero XMR.
The KraKen Triple miner is my most ambitious mining rig yet which uses 8 GPUs as well as a high end CPU I& 7700 to mine Electroneum. At the time of the build GPUs were really expensive and hard to get. But since the video I have been able to get enough cash together to complete the whole rig. I will do an update to this rig in the coming days.
The big challenge which rigs this size is knowing exactly what size power supply size to buy.
In this video I used the AeroCool 850 and 750 watt power supply which wasn’t enough to power a full 8 set of graphics cards. But it got me started. In hindsight I probably should have gone for the 1600 watt EVGA power supply. However the prices of this power supply are massive so I tired to go cheaper. In the end the AeroCool 850 power supply failed on me so I took it back and got the 1200 watt Thermaltake Power supply.
Once the power supply’s were in it ran pretty well. Currently I have 7 x RX 570 cards and 1 x GTX 1070 card in the rig. And getting around 210 Mh/s of ETH mining and around 300 h/s of ETN mining. In the end I got rid of LBC Library mining as the coin had very low value and the power consumption goes up with the extra mining. I might move back to an Ethereum ETH, Decred DCR mining shortly once to market turns around.
This setup was and is very challenging. For newer miners I suggested starting with one card mining rig and then move to a 6 x GPU mining rig. Actually I think the best solution is 6 x mining rig and these will be the ones that I build in the future.
In this video I got over CPU mining and I give examples of this by showing a old HP z800 Xeon computer that I was given for FREE. Actually I was given two of these computers. How did I get that? Well I asked for it, see in Australia allot of people are moving away from the older desktop style computers and moving towards laptops and mobile computing. So allot of these old boxed just get dumped in the street from time to time.
In this video I use this computer as a example of how you can use them for CPU mining. Something to be aware of is this would only be a great option for people who have access to free or almost free power. The reason for this is that this model shown is actually not very power efficient so just be aware that you might actually spend more money than you make on power costs. And actually I only ever use this computer for video editing as the cost to running it is high.
However lets say you have access to Solar power then running one of these rigs might be an option. Shortly I will be getting Solar installed. But even then it will only offset my rig The KraKen during the day still it will make mining even more profitable and at some stage I will do a video on the install of my Solar setup.
