Firmware for underclocking Antminer S19?

[MrT2000]

Hei, just made a account here.

I'm tinkering with a Antminer S19JPro and want to use it as a space heater. Using Braiins OS+ now but it will not let me set a lower powertarget than 1700w for all 3 hashboards. Is there other firmware i could use?

To make it quiet enough to be used at home and not overheat i need less than what braiins os can do.

[BitMaxz]

You can try asic.to but I don't think you can target lower than that since all hashboard are running.

Why not remove 2 hashboards if you want to target lower power?
I'm sure you will get the target wattage that you want from Braiins OS.

[MrT2000]

I did try to remove 1 and 2 hashboards, but the problem is that each hashboard run at minimun 6-700w and they overheat with silent fans. If i could split the heat over all 3 board i could keep them cool and silent.

I have a S9 with braiins, and on the S9 i can underclock each board down to +-130w and i'm able to keep it cool at 400w total, spreading the heat over all 3 boards. Enough to help keep my bathroom warm.

If the firmware on the S19j Pro would work the same as on the S9 i should be able to underclock it down to under 1000w on all 3 boards given that the S19J Pro have a normal power usage at 3.2Kw compared to the S9 at 1.4Kw. In theory..

okay the boards work with

all S19
and t21
and s21


When you under clock it allows you to disable any of the 3 boards

it also allows as low as 50mhz freq and 12 volts if you do manual.

you can also go way high like 600 freq and 15 volts
and that are the manual settings

more than that you can autotune from 60th to 300th   on the t21 I have.

the flexibility is huge much more like a gpu from the old days of mining.

You also may find you a board that allows really low settings and another board that allows high settings.

What is the point of replacing the board? Is it not enough to change the firmware from stock to vnish for example?

the epic is fee free vnish charges a fee.

so if you do 200th on a s21 at 4 cents a th  that is 8 dollars vnish charges 1.8 to 2.8 %


"Our software is distributed free of charge. Please note that custom firmware includes a developer fee (DevFee) - a reward for developers. DevFee depends on the type of equipment and is 1,8%-2,8% of the total hashrate of your miner, which is automatically debited while the device is running.

so 14.4 cents a day to  22.4 cents a day which is 52.56- 81.76 in fees in a year.  so right now if sha 256 sucks bigly it takes 2-3 years to pay off the controller

but if we spike to 8 cents a th vnish is 28.4 cents a day to 44.4 cents a day  which is 103.66 to 162.06 a year and the controller is paid off in 1 to 1.5 years

as earnings go up the epic becomes cheaper compared to using vnish


much like rent vs own a home each had a strong point.

Hello, I'm running my S19 at lowest power target under Braiin OS, 903 watt for about 30 TH with all three hashboard activated, and stock fans are enough silent at about 25-30%. It is an S19-90 with 126 chips. This is double the efficiency of my S15 with stock firmware in low power mode (900w for 17 THs).

Except your mathing wrong hashrate is worth less and less each day. Don't value it to fiat value it in how much btc we earn off it a day. On a 19 series we will never generate enough devfee at this point to cost more than a control board. If you want a control board I can sell you a control board for a quarter of the price ePic board is. we made a universal board 4 years ago when aml came out but then found an exploit so we canned it. We can also sell you firmware with no devfee if you were buying enough at cost cheaper than buying their board.

Also that is not the offical vnish. We are www.vnish.com and www.asic.to

why lie about what hash is worth when it is worth more than it was last week. and if btc rallies bigly the epic is the better buy than vnish.

now your arguement made sense up til this price rally in terms of what is the better deal.

i have  your  software
i have brains software
i have mara board and software
i have epic board and software


used all of them for years.


they all can be okay

and some times bitmain software is better for some people.

but to say that hash rate is worth less on the biggest jump this year makes no sense bro.

and yeah i will still use your software at times.

Do you not understand how bitcoin work. Hash Today is worth More then hash tomorrow. Difficulty rises btc profits drop every day.

Sorry you value everything in Fiat. Doing that will keep you chained to the fiat world!!!!!!!!!

Think about how much BTC you have to sell for FIAT to buy an epic board. Now think about how much BTC the devfee will really make over that same time period. Assume your mining with the miner for 2-3 years aka you can't factor in bull market pricing because the majority of the time you will be mining not during bull market.

but regardless we will sell license cheaper than ePic if needed.

Look how many competitors copied our autotune! The list get longer every year I love it!

You forgot LuxOS

Do you not understand how bitcoin work. Hash Today is worth More then hash tomorrow. Difficulty rises btc profits drop every day.

I am pretty sure Phill understands how bitcoin works, however, there is no right/wrong way of valuing things, you look at it from BTC perspective, he looks at it from fiat perspective.

In fact, I also prefer looking at everything mining related from a BTC standard, and when I do so, I realise that mining all together is somewhat a terrible business, in the vast majority of cases, the BTC you spend on gears and infrastructure is probably never going to be ROIed, you may ROI on your fiat capital and that is a different thing.

With that said, in the U.S and other places ( probably no other place lol) where the tax law is so complicated, it becomes a different matter than just fiat vs btc.

Yeah we are sadistic that is why we mine instead of buy btc. Pretty much there is only a few situations where mining was the best bet. For example buying S9's right before the run up you ROI'd in like 3 days. That was the god tier time to mine.
