Learning/newbie s9 zero hash 100% discarded

[favebook]

Ooof, that was a bad decision. You cannot run S9 unless it is underclocked on 110v.
For future note, you now know that you should read specs of everything you buy.

I feel bad for telling you it was a PSU issue, I assumed that the voltage range aspect is something that everyone knows but I was wrong, it's hard to assume what the other person knows and what they don't know. if you mentioned the 110v in the OP, then everyone here would have told you that you can't run 3 boards on it, but again, how would you know?

Anyway, if you ever consider upgrading to a new mining gear, know what 110v is not an option, not even when removing a hash board or two, the PSU won't run at all if not fed with the proper voltage which is above 200v.

... if it pays for itself running at 1/3 speed at a reasonable rate ill buy a better unit.

1/3? Do you mean 2/3? you can actually run two board on 110v, also, instead of stressing one or two boards while the other one sits there doing nothing try to use custom firmware like BraiinOs or Vnish and set low frequency and voltage, you can achieve some nice results by tuning the miner, the stock firmware sucks as far as efficiency is concerned.

Yeah my misunderstanding was pretty much that if the PSU was 110 then why Wouldnt it work since that IS the PSU for the unit.

But no worries.  That is exactly why im doing this like this to learn what i dont know.   and I would have no issues with attempting an upgrade of its firmware.  but i am lead to understand that i have to now play around with an SDcard which i might have one of that size in an old phone somewhere.

and also this unit if it is stable and ive run it for 12 hours now on a litecoin which looks like it made a whopping 45 cents.  which is rather poor.  but whatever.   I switched it to slushpool and put it on bitcoin.

This unit is going to be placed in a friends business where his power is paid as part of the rent.  if theres no complaints then i dont see a real loss.  the business is also heated by heat pump.  this thing cranks out heat so it might offset the heatpumps power use and electrical costs might even out.  Until summer of course =>

How did your math add up tho? They even have specifications which note maximum W on 110v HERE:

Rated Power(110V input): 1200 W

and also this unit if it is stable and ive run it for 12 hours now on a litecoin which looks like it made a whopping 45 cents.  which is rather poor.  but whatever.   I switched it to slushpool and put it on bitcoin.

Are you sure you mined Litecoin with your S9? S9s mine only Sha256. And Litecoin is using Scrypt.

There isn't much of a difference in how much fiat you earn by the end of the day, whether you get paid in BTC or any other currency, even mining different SHA256 coins won't really make a huge difference since the hashrate eventually finds a balance of some sort where all coins of the same algorithm end up making you the same profit, except for one of these coin's price goes up or down real fast compared to the rest, this usually gives you a few hours of more profit until things are balanced again.

One hashbaord (4.5th) makes about 60 cents a day at current prices and difficulty, and these days are glorious, profit is hitting the sky compared to the past couple of months, so if you are not happy with the profit now, I am afraid you will be less happy as you on forward.

Here is a good tool to estimate your profit beforehand https://whattomine.com/asic.

S9s mine only Sha256. And Litecoin is using Scrypt.

Some pools will pay you in any x coin you chose for Sha256 hashrate, for anyone who doesn't fully understand how mining actually works, they will think they are mining that particular coin even if it was a POS coin, I think this was the case here.

[favebook]

I sincerely hope so. But why would anyone use Sha256 and do payouts in Litecoin? Doesn't seem right to me.

There might be an option for him in pool to decide what is he paid in and that he is confusing that with what he is mining.

[mikeywith]

But why would anyone use Sha256 and do payouts in Litecoin? Doesn't seem right to me.

Maybe you mine bitcoin and get paid in another coin because you think the latter will outperform the former? just how other people mine other coins and get paid in Bitcoin.

There might be an option for him in pool to decide what is he paid in and that he is confusing that with what he is mining.

There is no other way that I can think of unless he magically changed the algorithm of his S9.

[philipma1957]

yeap 110v is whats available.  see im ignorant this stuff still.   id skip the new psu since this is a learning unit.   if it pays for itself running at 1/3 speed at a reasonable rate ill buy a better unit.

Again thanks for all the help people even if it wasnt specific info the talking to people was enough to get me heading the right direction.

This is a real shame as you loaded firmware without asking us.

You could use braiins and run 3 boards at 800 watts doing 10000gh

you still can but you will need to boot from the sd card slot.



If I recall the July 2019 bitmain shit ware that you loaded has an ultra low setting.  it can do 3 boards on that setting.

it will do about 9000gh. 9th and use about 1000 watts.

You should really look at my low sound low power thread as I have a lot of info on how to down clock the s9

the bitmain firmware you loaded is not as good as the brains aftermarket  but it is not a ton of money we are talking.

[Nhazwrath]

so on a 24 hour period on the slushpool it runs at average of 9.4TH (2 boards)

confirmed 0.00001920 and unconfirmed 0.0008910 translates in to about 2 dollars and 22 cents Canadian.  I prolly spent 4 on power.

Sound is going to be a serious issue and while i can locate a SD card im sure.  how to load the firmware On to SD card is the question im looking in to.  since nothing i have uses an old large sd card.

I was pricing sound board at home depot its 30 dollars for a 4x8 sheet  i dont think i need more then 2x2

a silly idea came to mind and i leaned a old used wifi router on a 45 degree angle against that whacky turbine on the back and that alone took off the high pitch.

[favebook]

You do not need big SD card, I use 8gb because I cannot find smaller ones in my house anymore, but whole firmware tanks maybe a few MB. All you need is to download LEGIT custom firmware, format your SD card and unzip the files to root folder of it.

[Nhazwrath]

so I have located a old 2gb sd card of mine inside an old galaxy note 1 its of the right shape and ive checked it already for being able to plug it in to the miner I am currently charging the phone.   Will i be able to use the phone itself to download the firmware on to the sd card? or will i have to locate some sort of interface for my PC to access the card?

[philipma1957]

amazon has cheap card read write

which you should have if you want to mine.

i will come back with amazon.ca links for you.

I have 3 of these they work really well with apple or windows

https://www.amazon.ca/gp/product/B072NCND62

the card below is bigger then you need as I can't find a good 8gb on amazon.ca

I have already told you what steps you need to take in order to prepare your SD card for flashing firmware to ASIC. If you can format SD card, unzip files to root folder of freshly formatted SD card within your phone, then yes, you can do everything with phone. But I always do it via laptop with SD card reader.

[philipma1957]

I linked a really nice read write for him above.  Well worth the price.

I can't find a good 8gb blank card link for him.

[favebook]

Yeah, just saw. Might buy it as well.

8GB and 16GB are not produced that much anymore if at all from reputable companies. They are not worth the material. That is why 32GB is a new minimum. In my local city shops, 32GB is standard and finding a shop with 16GB SD cards is like finding a block with Antminer S9.

[mikeywith]

Yes, you can, connect the phone to your pc and download the firmware on the pc, do any unzipping necessary before sending it to your phone, make sure you format the Sdcard using the phone, I have done this in the past, it works if you do it right.

[Nhazwrath]

I downloaded the brains OS image file.  I also downloaded that ether program And I attempted to flash the SD card like the instructions said I should.  The ether program reports that the brain's OS image file is corrupt.  Wiped out both tried again same problem. 

[favebook]

I am not sure which image you downloaded, use the official website. I am not sure what ether program you are talking about and why would you need it. There is no need for anything to check if image file is corrupt or not. You format sd card and download the firmware. I am not sure if braiins can be uploaded normally with upgrade button if firmware is from 2019/2020 but for previous ones it could. You should read this: https://docs.braiins.com/os/.

Otherwise, I'd advise you to try some of smaller firmware developers found on this forum. They have really good and simple guides on how to flash your unit.

[Nhazwrath]

from the site you you linked.

https://braiins.com/os/open-source/download

theres a few versions in there i downloaded the one pertaining to the s9 antminer: https://feeds.braiins-os.org/20.09/braiins-os_am1-s9_sd_2020-09-07-0-e50f2a1b-20.09.img

https://docs.braiins.com/os/open-source-en/Setup/1_quickstart.html#install-braiins-os  from the doc section I misspelled etcher when i posted the other article I was using voice to text on my phone.   The section talking about how to install the OS with a SD card when you have the version installed that normally prevents updates. it clearly says you must flash the SD card in advance and use the Etcher software to do it.  https://etcher.io/

I wiped and formatted the card on note 1 before removing it. I have not gotten to the part of the install for adjusting jumpers I used to debug mfms and rlls so I don't see a problem with that yet.

I was using an RCA netbook (win 10)which I haven't used in a few years.  I examined it to see if it had an SD card slot and it had one hiding that I didn't even know was there.

[favebook]

I have never used anything like etcher before because I haven't had any need for it. I'd advise against using it.

If you really want to use braiins, you can go to their forum/telegram or any other social media where they do customer support. There are quite good people there.

Otherwise, someone more into braiins here could chime in.

I'd even use Vnish's Asic.to before braiins, but that is just my preference.
