It was not set to factory when I started it it was set to performance.

I did not run it long enough to give a fair number. But it was 52th

I am pretty happy with efficiency I will run it till I go to sleep. It is loud enough that I won’t sleep well.

I will test factory in the morning and performance in the afternoon.

I was annoyed it came late but if I can get 45 or 46 th on factory - -

48:on factory and 52 on performance .

Okay  just fired it up and set to Factory

signs you in

the gui looks like  my t3 39 and like my t2 24

I use an hourly kwatt meter  more accurate then the instant versions but  you need to wait for 2 hours to get a decent measurement

I estimate  it will be about 5.4 kwatts maybe more for the 2 hours.

I will photo the  meter and post once  it starts  to mine and finishes tuning.
These take about an hour to fireup fully.

reads                   1165.76
1hr should read     1168.46  actual =?  1169  which is

1169.00
1165.76
      
3.24 or 3240 watts  doing 48 th  this is 67.5 watts a th on factory  not that good.

the gear is cycling which is a no no  I will see if it stops
I suspect that factory is not a good setting for it.



the meter is at 1169 kwatts at  11 am  we are  doing 48th on factory

I did have a lot of recycling for about 30 minutes which has stopped.

so I will test again   11am 1169 kwatts   48 th New York time on factory

I will let it run for a few hours as I want to be accurate.



It is doing very close to 49th at factory setting
In 18 minutes it will be 2pm it  be 3 hours since 11 am reading of 1169.00

so 1169 + 9.3 = 1178.3   that would be  3100 watts and hour  or 3100/49 = 63 watts I do not think that will happen



actual 3 hour reading = 1178.71
                                    1169
                                         9.71/3 =  3,237/49 = 66 watt a th at the wall  it is rated 3100/50 = 62 watts a th.  not sure it that is wall or dc rating.

so factory setting is okay  :

49 vs 50
 3237 watts at wall

webpage info below:

Innosilicon, the industry leader of all coin crypto mining ASICs, launches a new powerful BTC miner with enhanced performance. It adopts the state-of-the-art technology and reaches 50TH/S in high hash mode. In case of energy saving, this miner also provide a high efficiency mode with 33 TH at 1650W.

Hashrate: 50TH/s (+/-5%)
Power Consumption: 3100W ( +/- 10%, normal mode, at the wall, with 93% efficiency PSU, 25°C temperature )
Dimensions: 303mm(L)*203mm(W)*278mm(H)
Allowed ambient temperature range: 0-40°
Network Connection: Ethernet
Note: This miner not only can achieve 50TH (+-5%) at 3100W (+-10%) in high hash mode in case we want to maximize hash rate, but also has a high efficiency mode to reach 1650W (+-10%) for 33TH (+-5%) in case energy saving is needed.
Please make sure your farm use proper cooling, dust filter and 16A AC cable to meet the proper operating condition requirements.
Humidity <75%, AC voltage 210~240V, Power supply AC input current 16A, dust <0.5 Mg/m3."

so 49 vs 50 is 2%    1th lower which is spec
3237w vs 3100wx is 4.4% or  237w higher which is spec

of course it is 66watts a th  vs 61 watts a th  which is very typical of inno to do exactly this

I let it go for 5 hours to 4pm New York time

so
1185
1169
    16 kwatts spent which is 3.2 or 3200 watts  for 49th  that is   3200/49 = 65.3 watts on factory setting



The next test will be lowest setting   as 33th at 1650 watts is promised if exactly on spec it would be 50 watts a th

translation of that is  33th x .95 = 31.35th  and 1650 x 1.1 = 1815 watts  that is 1815/31.35 = 57.9 watts a th

if I can get it to do 52watts a th rather then my 57.9 watt guess I would like that.

I just set it to lowest most efficient speed.  I will wait till 5pm and get readings

oh temps read 69 to 70 c on my 3 boards at factory settings.

1187.51 is the 5pm reading.

34.33  is the hashrate  I will check it later   to see what we do with this setup.

if this gear does 50 watts a th  the 1 hour  meter read would be

1189.23.

Actually if it can do 50 watts a th it has some staying power down the road. If you can buy it at a lower price in a few months.



I tested at lowest setting efficient and I am really disappointed in the gear.

it does 40th at 2460 watts which =  61.5 watts a th so it completely missed  the promised low setting numbers of   33.5th and 1650 watts.



I won't order anymore of these.  I want to thank minefarmbuy  for  handling this in a professional manner.
I took the unit to buysolar's house and put in in the barn to us that solar  array
I cranked unit up to factory +   which seems to do 53th at 3600 watts that is 68 watts a th  a lot more than the advertised  62 watts a th.

for now with current diff and coin price  it is okay gear but  it will lose profit at a diff of 23.8   as it will earn 5.62 usd and cost 5.62  if coins are 10200 and your power is 6.5 cents

if the down clocked worked as advertised.  it would earn $3.53 and cost $2.57  to run it when diff is 23.8 and coins are 10200

for the record  I would return this  to inno if I could but I used minefarmbuy  which  does allow a return and minefarmbuy  takes the hit.

inno deserves a hit on this gear.  They completely missed the down clock specs  even if you add in the -+ ranges they blew it .

I would love to see if they put out a firmware that gives the promised 50 watt a th on low speed.

Till then I do not want any more of their gear.

If my testing is wrong  and I had a meter issue someone show the unit at low speed doing close to 33th at 1650 watts.
I am only human and would love to be proven wrong and that  the downclock goes a lot closer to the 50 watts a th promised.

Be advised  that 61watts a th is very far from 50watts a th in the case of the t3 t50  low speed setting.
