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 ~0.087BTC which is around 925$ currently.
If it was in Normal mode it would have earned ~0.072BTC+7days(~0.0084BTC)= ~0.0805BTC 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:

1st Batch:
Selling Time: 09 September 2019, 19:00 GMT+8
Delivery Time: 01- 10 November 2019

2nd Batch:
Selling Time: 10 September 2019, 19:00 GMT+8
Delivery Time: 11-20 November 2019

3rd Batch:
Selling Time: 11 September 2019, 19:00 GMT+8
Delivery Time: 21-30 November 2019

Rather than Turbo Mode, I'm more concerned about when we should be making the switch to Low Power Mode.

For soon to be diff of 11.9T, and price of $10250, break even between normal mode and low power mode is $0.1851/kWh power cost. That's 50TH @ 1975W vs 36TH @ 1296W.

So higher than $0.1851/kWh use low power mode, lower than $0.1851 use high power mode.

I have a s17 pro that keeps crashing.  Here is always the end of kernal log, any ideas?

Code:
2019-09-14 14:12:09 driver-btm-api.c:1184:init_fan_parameter: fan_eft : 0  fan_pwm : 0

2019-09-14 14:12:20 driver-btm-api.c:118:killall_hashboard: ****power off hashboard****



Just did a reset, and it's working fine now.  It's only this one s17p that gives me the issue.



Now down again.  I have searched everywhere for this and somehow can't find anyone else with same kernel errors.  Any ideas?

Top speed
Middle speed
Low speed

All tested and failed?

May as well attempt it at all three speed settings.

I only have one of them it is set to middle speed and is flawless.

If it fails on all three speeds.

Swap the psu with one of your good units .

See if problem follows psu.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.
