Ethereum Mining with Google Cloud (Nvidia Tesla K80) actually works and is highly profitable
I have read many posts on the internet that ask the question if Ethereum mining with Nvidia Tesla K80 graphic cards in Google Cloud Platform Compute Engines is possible and profitable. There seem to be different opinions out there and I have seen results between 13 and 200 MH/s but not a single comprehensive overview.
I configured a Compute Engine with 8 Nvidia Tesla K80s which costs about 4$ per hour (2900$ per month). Here are my mining results:
The average hashrate was 1721 MH/s. With this hashrate I earned 4167$ (14.10 ETH) per month. That is a huge profit of 1267$ (+43% return)!
It gets even better! Most cloud mining contracts have a really long runtime and the risk of mining profitability going down before you have your money back is high. Really good contracts pay back in about 200 days but most of them take several years.
With Google Cloud there is absolutely no risk because you don’t have to pay up front and can cancel at any time. That means that the payback time is just a few minutes. You can even change the specs of your machine on the fly by adding more GPUs, CPU cores, RAM or HDD storage while it is running.
Conclusion
I really don’t get why this works so easily. One would think that Google Cloud prices would skyrocket once someone started mining on them, but apparently only very few people are doing it right now.
What you should do
Get in on it fast! Once more people know about it, Google will either drastically increase prices or block mining somehow. I am currently enjoying my 1267$ of risk free money each month with 8 GPUs but I will upgrade to 4 machine so I can have 32 GPUs. This will make me over 5000$ a month. If you do so as well, I would be happy about a short reply to see how it is going for you.
Where is the proof? And not just a generic graph and screenshot of a mining calculator. Why are others getting 12Mh/s per K80? What OS, miner and drivers are you using?
That is bullshit. I have been working with k80 on the miner for the last 2 months and I know what the bottlekneck is and what the maximum theoretical hashrate could be. It could not be faster than 90MH/s but realistically it's more like 60MH/s and even then you need to resolve the bottlekneck.
since you have 8 k80 that means 8*60MH/s = 480MH/s.
A more realistic number would of been 28 MH/s per k80 so 232MH/s for 8 K80
I'm only getting 8MH/s per K80. How do you get 28MH/s?
Hello @grunzwanzling,
I'm really surprised by your post, i'm actually running a cluster with 20 GPU K80 and i'm definitely not able to reach more than ~250Mh/s.
I made long researches and tests on Azure and on GCE trying to optimize and setup the best as possible my miners.
Actually the K80 is reaching at maximum 15.6Mh/s per GPU.
I tried on Azure yesterday same results... also on GCE using 1 GPU K80 same results. I met a lot of people using K80 or who has used one and nobody reached 1700MH/S with 8 K80 GPU.
Can you describe a little bit more how did you reach that hash-rate : miner ? pool ? because that sounds totally scammy.
I'm only getting 8MH/s per K80 now with the DAG size increase. How are you still getting 15.6MH/s ?
No answer or further details? Busted!
COMPLETELY SCAM
SEE MY REAL TEST ON 8X TESLA K80
Actually this isn't an option, specifically says google blocking mining. :-(

STOPhey @grunzwanzling did you try mining any other coins with other algorithm like x11/x13?
No, I have not yet, it has been difficult enough to get Ethereum working and tweaking it to so good results.
can you share those tweaking settings? I am running Ubuntu 16.04 and ethminer with -U compiled locally, but getting nothing close to your numbers. Are you on cuda 9? What client? What version and what parameters?
