I got three test boards designed to fit in an s9

they do 5.3-5.5 a board at about 320 watts.

I may be able to get a lot of them.

since they are 52-55 watts a th they are not really cheap.

not sure if I can get 30 or 40 of them to make better 1 and 2 board gear.

i will post again

you can also look at hardware to see the test thread.



this is the newer better board thread.

https://bitcointalk.org/index.php?topic=5253561.msg54598149;boardseen#new


I have zero idea if I get boards in bulk
I have zero idea if price will be good.

but I would buy 30 boards at correct price.

yeah i just got online  i went to hardware and set up four threads for you to read.


this is the sales thread but I won't be selling anything for weeks. has info and photos.

https://bitcointalk.org/index.php?topic=5243761.msg54305587#msg54305587.  . . no sales for now


here are all mod threads.

https://bitcointalk.org/index.php?topic=5213936.0. not mine but a clever mod of s9's



the goal for all the threads above is to build decent solo miners for this pool.

I like these hash boards so much I ordered some better quality fans and will test some more.

I locked the older s9 mod threads.

I would not mind having three 1 board miners using these hash boards.

hashing at 6th and using about 320 watts.

locking this it will move downward. in step with the older thread.

setting these up and locking them

I have two threads in hardware.

I also sold six in marketplace.

I will link them in a bit.

my Mistakes. 

Not holding early mining gains.

I have had 57 btc free and clear and did not hold it.
It Was worth about 9 a coin.

At those prices it was cheap enough to hold.  Down side would be only a 500 dollar loss.

The lowest price btc I ever earned was 6 dollars.

The highest price btc I ever earned was 20000 dollars.

that is an expansion of 3333 to 1.

I simply do not see BTC ever doing an expansion like that. 3333 x 10,000 = 33,330,000 a coin. that simply won't happen.

I Think some lesser coins could do 100x. what they are now.

I hold 1,600,000 Doge. worth about 4100 usd.

I could see it being 10x what it is now far more easily then I can see btc worth 98,000 a coin.

My goal is to have 10,000,000 doge

or to sell all my doge if it reaches 10 cents before I get to 10,000,000 doge. that is about 38x bigger then it is now.

I still hold BTC
I also hold LTC

yeah I think they are from north carolina  hmtech



https://hmtech.co/

you can mention me.  I am not sure they repair z11's


but they fixed 2 of my  whatsminer 20s units.

anyone run amd 5500 and get progpow hashrate numbers and watt use.

do they make 10mh and 100 watts?

I am thinking of buying 2

Well I did not post here for a few days hoping to see an improvement.


It is quite impressive we are still over +15% with 999 block to go.

and price is around 9763

a fast calculation below

100 th at 50 watts. earns 9.07 and uses 120 k-watts thus

9.07 -0.00 = 9.07. with 'free' power.  and this does not count labor
9.07 -1.20 = 7.87. with 1 cent power
9.07 -2.40 = 6.67  with 2 cent power
9.07 -3.60 = 5.47  with 3 cent power
9.07 -4.80 = 4.27. with 4 cent power
9.07 -6.00 = 3.07. with 5 cent power
9.07 -7.20 = 1.87  with 6 cent power
9.07 -8.40 = 0.67. with 7 cent power

lets say we do go 15%. the 9.07 becomes

7.71-0.00 = 7.71 with 'free' power
7.71-1.20 = 6.51 with 1 cent
7.71-2.40 = 5.31 with 2 cent
7.71-3.60 = 4.11 with 3 cent
7.71-4.80 = 2.91 with 4 cent
7.71-6.00 = 1.71 with 5 cent
7.71-7.20 = 0.51 with 6 cent  power

I used 50 watt gear as my number because I think as of now the network may be close to 50 watt gear.

So what happens when a person misses a week or more.

If some one is on the list 60 days with a 10 he would have 600.

so do you do. 600/60 = 10.  or 600/68 =   8.82

At the moment I have six sets of my videos and photos.

1 in my safety box
1 at my bro in law in a different state
3 at home
1 set of photos on imgur
1 set of videos on  YouTube

The smile I just had is worth a few merits.

This reminds me of a scene from an old abbot and costello skit.

they bet on the three in the third race on march third.

the call of the race was as follows:

“there off you lose”


we are pretty much screwed either way the election goes.

We did back to back .99 cdf and we did 6 or 7 blocks of 10  over .92 cdf

the math of back to .99 cdf is 10000 to 1 shot.

then add in 5 of 8 over .92 cdf

odds are really high for that to have happened.

it is more likely the pool was under attack.

point shit miners that can't hit a block at nicehash to hide them  then rent from nicehash and point the miners to bitminter.   your cost is around 6%.

ie every 100 btc you get back 94 btc.

back in the day the math showed this was happening often.  to a lot of smaller pools.

in that 10 block stretch where bitminter had 7 of 10 over .92 cdf with a back to back .99 cdf

it became obvious to me that any smaller pool could be attacked this way.

I mostly moved to viabtc and nicehash  as you get .96 percent luck or better every day.

about .52 cdf for certain.

Small pools are subject to these attacks unless they have a lot of certain hash from a big miner.

kano.is  has made over 2500 blocks  first 1500 blocks they were .48 cdf really good number.

last 1000 blocks .53 cdf

long bad luck streaks kill off pools. 

You have a ton of other risks involved.

I am the main miner at mmpool.org

we have not hit in 2 years. plus   I am due 1.1 btc if we hit today.

So every day I am at constant risk of the pool shutting down.


I can't do this

at kano.is
ckpool.org
bitminer.com
mmpool.org

I have to point a lot of my hash at a certain payoff pool.

If you are in USA. you can send to hmtech in North Carolina. They are legit and have a contract with MicroBT.com. that is the actual builder.

I have contact info for hmtech

They have sold me 2 replacement p21 pSU's to be used with my m20s units.

Once. all the USA confusion settles with Covid-19, the protests and the riots over the Killing in minnesota.

My partner and I may purchase 2ph worth of m30s or even m20s

I have been using their whatsminer tool 5.0.2. it is excellent for remote controlling miners.

I have owned

1   m3
10 m10
1   m21
2.  m20s

other then 2 things

1) the people in Carolina have been good to me and  I am in NJ fast cheap shipping

2) plus I like the whatsminer 5.0.2 tool


Bitmain has been more reliable from jan of 2019 to June of 2020

I have

22 s17 pro
1.  s15
3   s17
1   t15
4.  s9k
2   t17e
2.  t17+
1.  s17+

they all work the worst are the s9k
also 1 s17pro is flakey


btw the guys in Carolina will fix the bitmain gear for me. have yet to fix them as they are hanging in there

I have to decide to buy gear this year to replace the s9's and the l3+ that I run

I may go with what miners.

right now I am doing 8.2 th at 463 watts 2 boards.

I could do 4.1 th at 240 watts 1 board.

yeah right now one router optimum has four or five miners.

they stay there for three to four weeks.

then move to verizon 96 to 100 miners.

all have longer passwords.  and i try to use only bitmain's virus resistant firmware.

which means you need access to sdcard slot to change firmware.

if you are willing to use simplemining.net and pay 2 bucks a month per rig the gear is very stable and you can access it from any pc in the world.


https://bitcointalk.org/index.php?topic=1541084.0


i point 4 rigs to him and pay him 8 dollar a month.

the rigs are in two locations one it 100 kilometers from my house one is 10 kilometers.

In the last year I had to check  on the units in person only 3 times.  well worth the 96 USD I paid for the year.

Exactly they are a non bitmain company .

They made 51 chip boards vs 63 chips.

But the pcb board is the exact size as an Antminer board.

Here are some screen shots. showing a two board  running. the gui mining status and the pool numbers.

this uses 616 watts. to do 11th. about 56-57 watts a th.

I need a lot more testing on this.

I will be making  a you tube soon.



since it is a non bitmain chip the freq range is different then the s9 chips.

low setting with tuning tries freq 450 with best volts/watts

pll option allows you to pick any freq from 450-570 and then try to tune for best efficient numbers

since my hope is building better space heaters I asked if I can go lower then freq 450 and use the pll tuning .

so I am trying 2 boards and pll freq 400 option.

hope to drop hash rate to 9-10th and power to 520-560

auto tuning takes more then 20 minutes

here is a nice feature temp of every chip.
look at middle board it is not connected in any way  reads -99



freq set of 400 yields

watts at 531
hash at 10.31
only 51-52 watts a th

this is actually better then expected

looked pool side and I get

watts at 531
hash at 9.84 th
about 53-54 watts a th.  this is what I expected to get.

I use this psu and volts supplied to it are 240

https://www.ebay.com/itm/HP-643956-201-1200W-HSTNS-PL30-Platinum-Plus-Hot-Plug-Power-Supply-643933-101/312798058602?

My braiins gear does about 85 watts a th. I can set it lower then freq 400. so I can do 300 watts to 350 watts with a two board miner braiins. but far less efficient then this gear.

I will run this at freq 400 for a few more hours

I will drop to freq 350   to see if we can get lower watts and not lose efficiency.

It would be nice to go to 475 watts and 8.75 th.  on freq 350.

---

here are freq 350 numbers.

the settings



the hash gui
note that fan sensor is weird I will replace fan to see if it goes away

---

replaced fan. and get correct readings so fan had a bad tach wire.
looks like at freq 350   watts are steady at 463

and hash fluxes from 7700 to 8400.  I am going to run over night to see if it gets a more stable hash rate.

I will also see viabtc long time avg

if it does 8000 at 463  it is 56-58 watts.  if it does 8400 it is 54-55 watts

has some promise I just got new s9 drop in kit from a builder

I can do 1  2 or 3 boards

3 boards on low give me 16 th and 900 watts  this is about 56-57 watts a th

2 boards on low give me 11 th and 616 watts  this is about 56-57 watts a th

I am thinking of making improved low power miners. using the s9 shell and s9 fans and s9 controllers and of course drop in these new boards.
