Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

[philipma1957]

hello i have s9 batch 2 and till now hw error rate was 0.0005% or 0.0006% its around more than 2 month but now i am getting high error rate especially in 3rd board now the rate is 0.0050% and more can anyone tell why is this problem coming and what happens because of higher hw rate ?

Wear and tear.  Yes solid state gets wear and tear.

Lower the freq by a little.



Basically you are getting 99.995  success  vs 99.9995 success.

If you are set on freq 600 go to 593  run it for a few days,

Every machine has a sweet spot.    And with aging it could change a bit.

According to you how much should be hw error %  ?

I can't get bitmain website to load.  I wonder if we are about to get prices pegged to BTC since it is going up.

Works here. Prices don't seem to have changed. 1442 and 1600 USD for B12/B13.

Well you were doing .0005. I would try to go from .0050 back to .0010

I would move clock by 6.25. Say 650 to 643.75
Or 600 to 593.75
Or 575 to 568.75
Or 550 to 543.75

I would run a day and see what the new error is.
If not lowered from .0050 to .0010
I would drop by 6.25 a second time.

Always checking for temps. Say 65 - 95. Or lower.

If two clocks down for  total of 12.50 lower does not work. I would look at the psu closer.

All in all .0050 is not great but is still okay.

Yeah working again for me too but the BTC\USD price is lower than in reality.  Bottom of page shows $593.  Stamp is at $604 and that's the lowest one I see; $612 on bitfinex and huobi.

There was a tweet from bitmaintech some time back that said that bitmainwarranty wasn't actually part of bitmain but clearly there is a closer relationship there than just some other random company.  Bitmainwarranty has a bitmain avatar (they were the last bitmain account to post in this thread a few posts back), they have access to parts that the rest of the world doesn't, and they can fix antminers (depending on the problem).

EDIT: found the tweet: https://twitter.com/JihanWu/status/697816867876921344

Wu was referring to BITMAINwarrenty, diff spelling

OUCH.

Still too pricey.

Hmm.  I have never seen bitmainwarrenty (not that that means there wasn't something back when the tweet was made) bit I figured he had just misspelled it owing to English not being his first language.  As an English speaker I would be pretty skeptical of something called bitmainwarrenty anyway.

Do you think they will ship without you paying first?

There are many other red flags in that listing, I wouldn't touch it even if paying by PayPal, especially after it's been bid up to $1575 last time I looked.

Location - London, I doubt any mining farm could be located there
Delivery - by mid-October (at least to the US, not sure of other locations)
Stock photo
30%+ discount for no reason (there is no newer hardware to upgrade to)

That's just from memory, too lazy to open that link again.

I decided not to proceed with the deal for various reasons but just to clarify:

Miners were in Guangzhou, China not London. I'll be in China in 2 days so I'd pick them in person.

Miners were used and without warranty hence the discount.

If I have some time to spare while there I'll try to understand if 2 btc per used S9 is a common price or not.

The warranty can't be worth 20-30%. The S9 failure rate is high but not nearly THAT high.

In other words, yeah the price is good, of the "too good to be true" variety. But there is probably a catch of some sort.

I understand that they price the miner at $1442 for B12, but what about NOT matching the btc price.
Currently, price is 4083 RMB, which is $610.82
OR coinbase price is $609.9 OR bitfinex $611.86

NOWHERE it is 1442/2.431=$593

Is it so difficult to link it to the "real time" price?

Hi all,

Recently I bought some of the S9 B12 miners. They seems to be pretty unstable and some of the miners require restarting and rebooting.

The other problem I have is that on few miners only 2 out of 3 boards are beeing deteted, one board is not shown in the stats at all. I'm using Bitmain PSU and I tried replacing the PSU as well as rebooting the miner and updating the software. Does anyone has any solution to this problem ?

Also on one S9 there're not boards detected at all and in the Hardware Version it shows: "   Socket connect failed: Connection refused"

Thank you for your help

Have you tried plugging the ribbon cable into a different socket on the controller?

Sorry for your issues.  You are not the only person with these problems.

 Are you in USA or Canada? If you are you may want to contact bitmainwarranty

I have a thread here

Got email saying my b13 s9 has shipped today.
So dem bones are still bouncing around. Especially since it my 7th s9, hoping they come up 7 or 11 vs snake eyes...

[sloopy]

So I get the dreaded x.
In the past this has lead to a failed hash board.
This is a B1 unit. The default freq is 650. It is possible this started a few weeks or so back. I know it wasn't there when I installed or shortly after.
I have changed the freq all the way down to 500 in increments of 50 with the same results.
The odd thing is something I think I learned from the sidehack thread regarding the way Bitmain has the voltage sent after it boots and does a couple of other things.
I get the x at exactly one minute displayed on the status screen timer.
Or maybe it is a cold solder joint, bad ASIC, or loose connection. That is why I am asking for input from the best minds in the game regarding the options.
I guess the ASIC # does not mean the current number of running ASICs?

I have also ran it in slightly cooler and much cooler temperatures.

Any opinions are appreciated.

[yslyung]

it magically comes & go at the same spot ! jeeez

"X" marks the spot ? i noticed few are seeing the magical "X"

well before bmt posts, my voltage is 12.4V on load ! so it ain't a PSU problem.

nope I am guessing this gear is simply less durable due to chip size of 14-16 nm

I think a lot of units are going to fail at a higher rate then any other bitmaintech product.

Symptoms seem to be happening with many miners in many places.

I suggest to down clock  a bit always keep temps at 65-95 as best you can.
Hope for the best with the gear.

I had 2 ship on June 12th they will be off warranty on Sept 12th > one dead board after 70 days
I had 2 ship on June 21st they will be off warranty on Sept 21st
I had 1 ship on June 27th it will be off warranty on Sept 27th
I had 1 ship on Aug  17th it will be off warranty on Nov 17th >>>> this had a dead board in under 10 hours

This gear could be very painful if it continues to fail for lots of us.
