Going to try to break down math better for turbo vs normal.
Your stats will help. Down time vs turbo gain.
Since I do not see that you did the math, I took it upon myself to do it.
S17 Pro 50TH/s in
"Normal" mode has a speed of
51.5TH/s.
In
"Turbo" mode I do not remember what speed it had but let's take the best case scenario and say it was
62TH/s.
I will skip the cost of electricity in my calculation but I will write it down here so if anyone is interested.
51.5TH/s in Normal mode is around 2kW and 62TH/s in Turbo mode is 2800W(as per Bitmain's specifications).
Mothly cost of electricity would be:
145$ in Normal mode and 200$ in Turbo mode.(I pay around 0.1 USD per kWh).I had the unit(working properly in Turbo mode) from begining of May until end of June, so I'll use 2 whole months for my calculation.
Downtime for shipping and return of the product was exactly
7 days.
And
cost of shipping was
300$(from Serbia to Netherlands) by DHL.
While the machine was working(in Turbo mode) it earned ~0.087
BTC which is around 925$ currently.
If it was in Normal mode it would have earned ~0.072
BTC+7days(~0.0084
BTC)= ~0.0805
BTC which is around 860$ currently.
2 Months difference + 7 days of downtime on Turbo (925-860)= 65$
Monthly reward difference (462-384)= 78$
(300-65)/78=3.01
So, for my unit to start earning more than if it was in Normal mode all the time, I need to have it on Turbo for at least 3 more months without it breaking again.Hope this will help someone make a better judgment whether to use Turbo mode or not. But I will be staying on Normal mode from now on.
Also, if anyone is interested, Bitmain just announced on Twitter that they are releasing
Antminer S17e and
Antminer T17e.
Both units have
shipping dates from
1st to
10th of November 2019. And both
prices are
TBD.
Antminer S17e has a speed of
64TH/s with power efficiency of 45.00+10% J/TH (same as S17 Pro on Turbo mode).
Antminer T17e has a speed of
53TH/s with power efficiency of 55.00+10% J/TH (same as T17).
This seems like a move to counter Whatsminer's M20S and M21S.
Additionally, here are future batches which I love to see Bitmain disclosing:
