Okay took me a while to understand terminology.
Also we are doing 3 units.
t17
t17 +
t17 e
Failed means it is under tuning. I e it should do 50th and does 49 th
tune okay means it is at or over the mark.
I am going to fully rate and test the t17 today.
after 10 minutes my latest test with a good meter says tune is okay.
this is full size click to link:
https://i.imgur.com/ljcARud.pngit projects that it should do
36018
36583 is what it did after 10 minute test that is higher then projection so tune is okay
this unit is set to freq 605 fans at 38% and mv at 1645 I did this to keep noise levels acceptable for my wife.

https://i.imgur.com/mhNVTP8.pngNow I have an hourly meter that does kwatts
at 4:50pm it read 91.28
so 5:50 pm = ?
it should do 40th at 2200 watts = 55 watts a th
since I am at 36.5 th x 55 = 2007-2008 watts
so the meter should move to 93.28 or 93.29 at 5:50
I have found a 10 hour read to be very accurate for power use.
temps are really good for 38% fan speed.
t17 specs are from here:
https://support.bitmain.com/hc/en-us/articles/360020445993-T17-SpecificationsI am running the t17 at viabtc

https://i.imgur.com/5mwhmkO.pngmissed the 1 hour meter read.
the 2 hour read is as follows
94.98 6:50pm
91.28 4:50 pm
3.70
3.70 kwatts in 2 hours = 1.85 kwatts or 1850 watts
36410 gh so
1850/36410 = 50.81 watts a th. that is well under bitmains 55 watts a th
and viabtc says the hourly avg is 37.26
better then the gui.
if the viabtc number holds you get. 1850/37260 = 49.65 watts a th
that is good. if it keeps it up.
I will check back and do more watt readings.
100.46 at 9:50 this is a 1836 watts per hour avg for 5 hours.
96.80 at 7:50 this is a 1840 watts per hour avg for 3 hours
94.98 at 6:50 this is a 1850 watts per hour avg for 2 hours
91.28 at 4:50
1836/36396 = 50.44 watts a th
pool shows 37.37 th or
1836/37700 = 48.70 watts a th
this firmware charges 1% so far it appears rate has been 1.136%
I will show calculations I did for that.
My garage got too hot and with lowered fans unit was too warm.
So at 11:52 I rest the gear at lower freq and lower mv
my meter read 103.79 kwatts last night and now reads 115.69 kwatts
so I used 11.90 kwatts from 11:52 to 7:52 or 11.9/8 = 1.4875 kwatt an hour.
the gear at freq 500 and mv of 1635 tunes okay does 29.828th on GUI and 30.08th on viabtc pool
so 1487.5/29.828 = 49.869 watts a th. vs 55 watts a th at bitmain firmware
and 1487.5/30.080 =49.451 watts a th on pool stats
so a good improvement in efficiency is happening on the 36th to the 30th levels of hash
I really like the auto fan setting at this lower hash rate of 30th the fans are running at 2520 to 3120. This miner in my garage with a minimum of sound proofing can be used to solo mine. As for fees
it did 7172 shares over last 8 hours.
7037 at 32.8 diff
1 at 4.1 diff
108 at 4.1 diff
26 at 65.5 diffthe bolding is the dev fee
7037 x 32.8. = 2308136
1 x. 4.1. = 41
108 x. 4.1. = 4428
26 x 65.5. = 17030
total adjusted shares 2329635
fee is 17030/2329635 =. 0.0073101 or under 1% after 8 hour test that will alter and flux a bit as he does a take out every 2 hours so you can go over and under the 1% fee depending on when you do a reading of the shares

I really like the t17 firmware especially with a 1% fee
you can really do some low settings with it if you want it to solo mine on solo.ckpool.org
It will get really quiet. I won't be able to do high settings until I go to the farm with it.
But I am very tempted to set it to freq 300 and 1620mv
I would like to see if fans drop to under 2000 at that setting along with watts under 1000
this firmware will make your t17's into space heaters that mine solo if those setting work.
Once I move the gear to Clifton I can go with a setting like freq 670 and 1680mv that should do stock speed but save watts and keep temps lower.
120.14 kwatts at 10:52
103.79 kwatts at 11:52. an 11 hour reading
16.35 kwatts
16.35/11 = 1.486 kwatts to do 29.830. or 49.827 watts a th.
I get 29.97 th at the pool or 49.58 watts a th
dev fee was
9209. x 32.8 3030552
1. x 4.1 41
108. x. 4.1 4428
36. x. 65.5 23580
23580/3058601 = 0.77% fee
I am done testing it at:
auto fan
freq 500
1630mv
next test will be
auto fan
freq 360
1540 mv
I will then move to the t17+
I will do full speed tests on the t17 when I bring gear to Clifton NJ
we are doing 21.075th
at freq 360
and 1540mv
fans are 2400__2400__3120__3120
chip temps are
54-60-52-58
52-62-53-60
54-59-51-57
room is hot about 90f or 32c
Meter reads
120.72 kwatt at 11:20
122.67 k-watt at 1:20
I will get back to power reads.
that is 1.95 /2 = .975 k-watts
so 975/21.073 = 46.2677 watts a th quite a bit lower then stock 55 watts a th. of course it does 21th but it makes the t17 a quiet space heater for the winter.
The t17 mod is very effective on all my under clock and under volt tests.
