I have over 70 sha 256 miners mining about 2.1ph  I have 8th on brains  the rest on stock firmware.

To be fair  I have over 1 ph of bitmain gear purchased via paypal.  Thus a real warranty good unit May-June 2  So I won't bother touching this gear with after market firmware until June.

Why do they allow such a low minimum bid?  Well this certainly put some pressure on coin prices. But it is only 4041 coins  which is around 2.2 days worth of mining


2.2 x 12.5 x 144 = 3960

I am not sure if you can get past the hard reboot.  I know some have claimed you can but no one that I know has shown a method to do so.

I know you will have over 500 units which means more then  50 rasp pi's

If you use a  few pdus with hard power off options  and 20  rasp pi's per pdu.

It is 20 instant reboots.  Then a  new ssh can be entered for them.  I also know this is not as fast as you want.

But as I said  I don't know of a quicker way then this.

Hmmm   weird but worst case mine it on low  as 925 watts and 17.5 th  is pretty good.    52.87 watts a th. and fairly  quiet.

So back to my main account.   I did this to show you what the mod may think you are doing.

Okay  then mod should make a note that the 2 profiles are different.

but spelled almost the same.

If it is a clone of you and is under your control  it is considered to be the same.

As to what  you  should buy next.

S17 pro with 3 speeds

s19 pro with 1 speed

I would buy an s17 pro with 3 speeds.

Basically buying s19 pro with 1 speed means you are going to need to use aftermarket firmware.

I have a mix of

s7ln      1 piece
s9       19 pieces
s9i        4
s9k       4
s15       1
s17       1
s17pro 14

t15        1
t17        2
t17e      2
t17+      1

avalon
a721     1
a1041   2
a1066   2

whatsminer
m10     2
m20     2
m21s   1

innosilcon
t2t24    1
t3t39    1
t3t50    1

and  of all that gear above  I need to run 6 units at less then top speed or they overheat and crash.

So to me  I will get:

1 s19 pro
1 s19

work with them  decide if they are okay.   If they have 1 speed they are not okay.

I will look for a low priced s17 pro with 3 speeds.

I do not use any aftermarket firmware on all of the above

except for 1 s9 it has braiins.

having a 3 speed s17 pro or s19 pro if it does that  is my choice going forward.

My 14 s17 pros are all under paypal warranty so I do not fuck with aftermarket firmware.

I was sent a Pm today.

Since they are supposed to be private.

I won't say who sent it on behalf of this idea.

I won't say what the pm said. Other than I got a link to this thread.

I did read the entire thread.  I will comment on it.

I won't get involved in the project as I simply won't have much control over my invested funds.

I do know a few of these investment groups have turned a profit.

Maybe this one will.

Good luck to any and all investors in this group.

Okay compared to mine  it runs poorly.

an extra 150 watts and .5th less

I kind of would touch 50 watts a th   while you  are doing  60 watts a th.

I have seen meters be 50 watts different at 1000.

so I could be 950 watts and 18th = 52.78 watts

you could be 1000 watts and 17.5 th  =  57.14 watts

Lastly I measured a 90 day old machine
You may be measuring a 400 day old machine

Of course  silicon lottery is a factor  but it does look like yours is ay least 5% worst then mine was when I measured it a year ago.

I can  check my hashrate for it  in 2 minutes

it is 27.32th over the last day on high.
I do not have ability to check power use unless I drive up to the site.

I liked this machine  it was a good home miner on low setting.

here is a screen shot of it running

It is better on nvidia  but my vega's  were decent with it.

I have zero idea what s19 pro   firmware will do.

But if I make a ⅓  miner for home mining I have to make it not that loud.

If the s19 pro has 1 speed.  I will need after market.

can you put it on low?  i think i would do 900 watts and 18.2 th

i would be interested to see the numbers you get.

Yeah buying cheap s17 pros  sounds good.

I think I am going to trying to make 3 units from 1. s19pro   get taserz to program them to do lower watts  like 900 and do 36th

then see if there is a market for a 36th 900watt miner. for home owners.

these will not be cheap  as  3 boards need 3 cases and 3 psu's and 3 controllers.

I estimate a controller and a psu to be  250 usd .  A case may be only 50 with modding a set of s9's and adding 4 new fans

so add 300 in parts for 1 unit 600 in parts for 2 units.

so a 2400 miner add 600 = 3000 in parts for 3x 36 th 900 watt miners.  so add 200 for my profit labor and design. Then 50 to ship it maybe I could sell a model at 1250.  that would be 3750 for 3  or 2400 for the loud one.

It is a fair markup for a custom pretested design with preloaded software. I would even kick a piece of this back to kano and ck since they kind of did cgminer which bitmain robbed. calling it bminer.

most likely it is just a pipe dream on my part.

it may be able to run  1 17e using 2 c13-c14 cables  along with 1 s9k with 1 c13-14 cable

make sure the cables are 14 awg and or 1.5mm

I am not sure it will work only maybe as I do not know if the sockets are wired  to do 10 amps each total of 30 amps.

So I can only say maybe.

Agreed but at 8500 a coin the new model does not look very special.

In 65-70 days ½ ing comes and the new gear barely turns a profit.

Nah  I can tell you that is not a move they would make. The $$$ lost in dropping price down to 8500 from 10500 is too much to bother.

359 days. since july of 2012

They gave out tens of thousands of dollars in coupons last fall and allowed paypal purchases .  Pretty much was a promo to buy gear for Oct and Nov 2019.

conveniently located in Australia 🇦🇺 so shipping will be 250 usd a unit to almost any country in the world.

you buy the two and lose 400 in shipping.

I know you have a lot of these to hook up.

I also know you need to be able to alter watts usage.

Maybe having 1 pdu with 10 rasp pi's attached that you remotely power on and off  allows for 10 rasp pi reboots in 1 shot.

if you have 12 x 841's to each rasp pi  it would instantly make them all  (10 x 12= miners) able to take a new set of ssh commands.
