I understand its deployed but if your trying to sell it here your going to have a hard time without some good merit here. Good luck
OP, I woud love to give the firmware a try as well.
I love this picture of you Mindtrip

no need. I am happy how it is.

thx, that is very kind, but my "system" is already deployed on some thousand S9 and S9i miners.
myself I am owning 2000 S9/S9i and 400 A3 - so no more proof and/or reference needed.

If your not interested thats fine with me just offering as I have done it for other new forum members offering services or software
June 07, 2018, 02:13:10 PM
I only suggest it as a newbie here to have a forum member test the software and do a write up about it small cost to help others feel comfortable in buying your software
June 07, 2018, 01:19:38 PM
no, it is not for free and it is not "custom firmware" - so no open source. sorry
June 07, 2018, 01:17:25 PM
are you willing to provide a vouch copy for review? I would review and post my experiences here on the forum
June 03, 2018, 02:46:18 AM
@ DolleTeam, please update, I see another company selling firmware online now BTW.
Any firmware for the s9i or t9+?
Thanks, he's the site I am seeing from a youtube link.

so what?
even 14TH machines are running the same firmware and the results with same freq/mV are same as well .....
ASIC chips are same make, same foundry but different quality (which is a normal matter of production process).

Your stock speed is 13.5TH/s. There are 14TH/s auto-tune machines out there, after all.
April 25, 2018, 02:20:44 PM
I testet it on a March 2018 Batch - it is a 13,5 TH S9
No, I selectet 631MHz, as I know, that this is 13,5 TH in total. Stock speed??? There is no "stock speed", there is usually "autotune" and the controller board is checking, which avarage of frequency each hashing board (chain) with the 63 ASICS is able to perform to reach maximum 13,5 TH.
If you have read the bmminer source code, you will have recognized, that the firmware is limiting the possible hashingrate with a maximum of 13,5 TH. So any increase of defined parameter which would lead to a higher hashing rate is not possible.

What S9 batch did you get? You said 631MHz, so auto-tune, but at what stock speed? You may just have better hardware than I do. I can only get 12.2TH/s @ 600MHz, 840mV.
I'm on North American electrical, so staying under 1440W total power is critical to me.

strange:
I was just testing your info: 575MHz, 840mV, 12,4 GH/s (ideal) - 12,2 GH/S (RT)
And I was testing that: 600MHz, 840mV, 12,9 GH/s (ideal) - 12,6 GH/s (RT)
Finally at 631MHz, 865mV, 13,5 GH/s (ideal) - 13,5 GH/s (RT)

Bitmain's GitHub provides enough code to build your own bmminer, and that means enough code to hack your own bmminer.
Voltage can go as low as 7.94V or as high as 9.43V. So yes, you can undervolt, and it remains stable but not full speed.
Data points: 13.5TH S9 @ 575MHz fixed frequency and 8.4V gives me a consistent 12.05TH/s. Same hardware @ 600MHz and 8.55V gives me 12.7TH/s. These are both significant undervolts; a stock 13.5TH/s S9 at fixed frequency will take 9.00V.

My mining facility currently has about 125 S9s in it and is air cooled, similar to the way Yahoo data centers do it. I recirculate hot aisle air in the winter to keep the cold aisle around 55F. The rest of the heat, and all of it during warmer seasons, is vented out the top of the roof by natural convection. Only fans other than the recirculating one are those on the miners, plus two small units at the top of the cold aisle that exhaust any accumulated hot air at the ceiling of that aisle. e.g. My facility was designed for mining, its not a retrofitted data center.
Water cooling is efficient, in terms of extracting heat, but your still releasing it into the environment. Any hot water you eject is either going into a ground loop and heating the soil, or into a stream and heating that water with associated environmental impacts (reduced oxygen capacity of the water until it radiates the extra heat to the atmosphere for you). Hopefully your using a closed ground loop.

interesting how you are keeping even in winter only with natural convection the air that cool. And more interesting how that works in summer. The building size is a factor and the region as well. I know farms in Iceland, but that isn't smart as everybody knows. We designed a solution for maximum mobility, easy to roll out and possible to be placed everywhere at places with cheap energy.

I do not know what your mining facility is looking alike, but modern data centers are cooled and that needs energy.
For example: a room with 60m3 (similar to one 40" sea container) equipped with 100 units of S9 is regular heated with 150kW.
That means you have to get rid of the heat produced. Assume you would not open the windows and the ambient temperature would be 25°
(which is the reference temperature of the energy efficiency of any electronic), the 100 units of S9 would let increase the temperature of
that room up to 120°C within minutes. Finally you have to blow out that heat with big fans and try to cool down.
Such cooling system needs lots of kW. In average air cooled mining farms need about 25-35% of their total energy costs for cooling. And the result is hot air released to the atmosphere ....
We are exchanging the heat with water and that could be used pretty easy and is way cheaper than old fashioned air cooling.
by the way: as energy is only 10-35% of the revenue, increase of TH is increase of profit. You will never increase TH that much without liquid cooling!

So 2500 watts for 20Th = 125 watts/TH right? A normal 13.5 S9 draws ~1452 watts for about 108 watts/TH. So running at that speed decreases efficiency about 16%, and requires submerged cooling. Other than bragging rights and maybe noise control, why would one want to do this?

13,5 TH miner achieves between 19,5 - 20,5 TH/s
BUT this is mandatory to a submerged cooling system and a 2800W PSU
Power consumption is about 2,5kW @ 20TH/s
Fan - OFF
temperatur is up to your needs: we can regulate it between 50°C and 110°C
All temp settings are running without any HW errors
