Topic: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order - page 186. (Read 531173 times)

There is always a market for older generation gear. S5 sold for the same price in December 2015 as it did in January 2015 after btc prices shot up and the s7 was hard to get a hold of

thanks I saw the word aluminum let me check.

it reads bitcoin miner model:s9 the material aluminum electronic components etc use for get bitcoin by operate

the other one reads

bitcoin miner model :r4 the material aluminum cn


maybe I can get some relief.





@ longsnowsm

there simply won't be a new piece of gear from them.

they are head and shoulders above any other company  take a look at hashnest  they sell cloud s7's  that still earn a good profit  never mind the s9's they sell
  they have zero need for an s10 or an s11 at the moment.

I was looking at the beginning of this ANN for the S9 and it appears that they announced the S9 at the end of May with shipping in the middle of June. 

Did we have any other clues that they were about to release a new miner at that point?  I am trying to understand the amount of lead time we might get before they announce the next generation of miner.  Obviously the more lead time allows us to move the existing gear out to make room for new miners. 

So I was wondering what your experience has been with this.  If you had a S7's did you have any issues getting them sold once the S9 was out?  Or did you sell them before the S9 was released?

Phil, check what fedex has it labeled as. Mine was labeled scrap iron/steel. A quick call to them to let them know it was computer hardware and they zeroed the bill.

That is so much bullshit ...

they will definitely sell more R4s; S9-who knows?
My prediction is that they might do S9-LN (with two boards) instead at some point.
Not sure with or without PSU.

I honestly hope they pull the plug on sales. Its the only way to keep the diff from going crazy with these prices. It would be nice to have a 6 month window with no new gear at all like when the S5 ended and nobody had anything for quite a while.

Honestly unless your brand new to mining I don't see how you can't have all your S9 miners yet with 22 batches out over the last 7 months.

Has Bitmain given any hints as to when they will have S9's available?

Yeah  My r4 and s9  were inside the same week   Dec 7th and Dec 12th

so they combined the value and taxed me.

Hey phil  I just read you got stuck $78 in customs?

WTF?

I sold most of my s9s off including 2 to sloopy.  And I think sloopy's 2 miners had a pair of replacement boards from bitmainwarranty.

The gear was never overclocked and temps were not allowed over 100c

I have 2 and ⅓ miners left
Buysolar has 2 miners 1 new and 1 old

They still work.

If you add the 4 dead boards from the 2 I sold to sloopy this brings my gear  fail rate from 7 of 28 to 11 of 28.

Last I spoke with sloopy  he had 1 dead board from the gear I sold him. So I guess 3 more failed.

I sold him a full s9 and a ⅔ s9   for 2k  so add back say 700 in repairs and he spent 2700 for 20th

the sad part is  2700 for 20th is cheaper then getting 3 new avalons  which will give you say 19th

at 3 x 888 = 2664 plus a controller for 60 = 2724 and of course shipping say 150 so net is 2874  and the gear does .16 watts per gh,  Bitmain is the king of asic 256  and truly owns "btc".

I am fine with that in every way but one China can decide to go after that company and poof  they are gone.
What happens to BTC if bitmain gets shut down?

Back to gear breaking.   It is obvious the s9  is designed to be unreliable. why is that?

the only way to beat a free or cheap power guy is sell him shit gear.  Most of us mining know we need cheap power and have managed to find it.  So if we buy gear we are certain to make money.  So bitmain keeps an edge against by sekking shit gear with a shit warranty.
   we still buy because in sloopys case 2000 for 20th  became 2700 for 20th and that still crushes avalon 721.

an aside  to sloopy  I can not get those 2 fans to work not sure why but they are delta and I had some other deltas like them with cockeyed wiring will still play with them some more.

I missed saying merry christmas to you but Happy New year ( I am early for that    )

Hmm, thinking the main firmware on the hash board is fine, but it is the individual chain / chip firmware that's corrupted. Each individual ASIC chip looks like it has its own test ICSP connection. I think they get a copy of the app that is sent to each chip, that runs in its own memory space on its own hardware.

Not sure why they would all fail at the same time, or if it's the chain that failed somehow. Need to do a deeper analysis of the data on these ICSP connectors soon.

It's currently reading the main PIC, and it appears to be just fine. Then it tries to "restore" the 3200 block "app" package to the chains / ASICs, and that's where it fails. Then it goes on to trying to test the ASICs and reads nothing because their operating software is corrupt or badly written.

Chain[J4] has 0 asic
retry Chain[J4] has 0 asic
retry Chain[J4] has 0 asic
retry Chain[J4] has 0 asic
retry Chain[J4] has 0 asic
retry Chain[J4] has 0 asic
retry Chain[J4] has 0 asic
miner total rate=0GH/s fixed rate=0GH/s

I think that's the sign that the asic app software is corrupted / munged up.

It's another avenue of attack anyway, will post results when I have the time.

 

i think latest batches more stable than first one
i have there latest S9 B23 14TH
and it's temp lower than B12 11.85TH
they both have latest firmware 29Nov
we are in winter now and the temp lower than 10C

I read it a few posts up:

Since when is Sidehack repairing s9 hash boards?

Another experience here regarding S9 repairs.

Out of five S9 units I have been through five hash board repairs and one IO / control board replacement.
I used bitmainwarranty for various reasons, but mainly because of the time involved. My longest repair took two weeks.
The pricing was $175 +$25 shipping three times, $132 including $25 shipping once, and $150 plus $25 shipping once.
I purchased the IO and control boards and did the replacement myself on that issue.

Odd thing is two of the S9 units I have purchased were from a great forum member who can mention his name if he wants and four of the hash board repairs were from those two units. All have been ran in the exact same environment and I know this forum member takes great care of his equipment. He provides a great deal of advice and reviews here. Simply luck of the draw for me.

What I hope to see is the S9 be around for much longer than the past generations. We went through a period with S5s where you couldn't buy them for less than Bitmains list and Bitmain even went dry for a long time before the S7 was released so difficulty was much more controlled. I am not expecting the difficulty to be reigned in the way it was but the lifespan of a miner should exceed 8 months.

What I am getting at here is the 14/16 nm process. I expect to see Bitmain release new models, make improvements in various areas, etc, but I do not expect to see another die shrink anytime soon. If more effort is put into tweaking S9 performance we may be able to squeeze much longer life.

When you see an S9 hashboard providing approximately 4TH each it can put the competition in a different perspective. Truly price what you have gotten from your S9 experience against the competition and you may find the 6TH, etc much more cost effective, IE Avalon. Personally, Avalon didn't sit well with me by not accepting BTC as a payment option. This is our business and a company in this field refusing BTC as payment starts to rub the "principle" side the wrong way. However, I have been beaten to hell much less rubbed the wrong way by Bitmain China so many times I can certainly stand to be RUBBED wrong in one way or another from some competition.

The S9 failure rate is completely unacceptable and I have not purchased another one. I am selling and will continue to sell everything except the S9s, my PSUs, some spare parts and cables. I plan to keep mining and am looking for an opportunity to purchase a bulk order. I have been attempting to find something worth putting a significant amount of cash in for almost a year now. I wanted to purchase x00 S9s when they were released and thank everything good I was ignored by Bitmain. If I had ended up with the same failure rate % you all would be sick of reading my complaining by now. When I tried to discuss the purchase via e-mail,  no answer. The Avalons price per TH was too much but it is time I should revisit that price.

Now it appears we have a couple of sources and Sidehack will have offerings on something with a decent amount of hashrate. That is the single reason I have held my S3 and S5 miners. I knew IF sidehack was able to get chips he has the ability to put a retro kit out and there is one thing I have zero doubts about and that is sidehack addressing a warranty situation. He does so the same way I treat my customers. The old saying above and beyond applies to his business and this is not words, this has been my personal experience with products purchased from him. I have always looked at how I can give sidehack money and couldn't be more excited to lurk in his threads regarding progress. I believe he has the ability, knowledge, and resources to pull in as needed if / when he reaches a position to scale up quickly. Myself and several others with electrical experience from basic to advanced have offered to drive over and help.

My parents generation was the Vietnam war, not WW II, but that generation still believed in taking pride in your work and looking towards a future with your customer base. Basic business models in this type of industry has proven time and time again that a small investment in customer service and support now pays huge dividends over the lifetime of your company.

Basically Bitmain have turned so many of their customer relationships into a vengeful type of "I buy from you because I do not have another choice." It has been and still is a long time coming but I can actually see the landscape changing. We will eventually have other choices. I was "first in line" to buy the S7 and S9. Unless I have another choice I will probably still purchase whatever next gen is released, but, I do it because it is what is available. Now, I do want to say my experience with bitmainwarranty in Colorado has been good. I have previously stated I firmly believe there are people working through that site who get it, but are controlled by policies put in place by the CEO in China and he cares about his existing largest accounts who are repeat customers.

In that vein I firmly do not believe the cheerleaders or fan boys who will not have a mature conversation regarding bitmain current failures. Do not take my comment wrong. I know there are people who have purchased bitmain products over the years who either have not experienced issues or, have been through what they consider to be good experiences with an issue. However, failing to recognize issues which continue to plague many of us and only cheering for Bitmain simply shows me how worthless ANY opinions put forth by such a person are not worth reading, much less a new miner trusting. People have expectations when purchasing certain equipment and electronic devices costing upwards of $2,000.00 should come with excellent support, turn-around time, optional cross-shipping, explanations of repairs, used parts marked and openly noted as used, etc I would never send a used part to a customer without first discussing it with them.

At least we are able to have the S9 hash boards "repaired." If I had known sidehack was repairing these I would have been discussing it with him. It isn't that bitmainwarranty in Colorado have sent me back unrepaired boards but for the price and the lack of details not to mention what sidehack does for this community I believe more of us should find ways to support his endeavours.

Good Luck to all of the home miners. Just since my short time of mining since 2014 so many people have departed. Hopefully many are still involved in various ways. The price of coin is nice and I hope it at least holds around $850 but I fear another drop as I recall the $190s and spent way too many coins around that price range. If I'd only held everything I made in 2015 rather than going all in on S7s  I would be at a much higher P/L ratio.

they have a direct relationship with bitmain.

if you are in the usa sending to them for out of warranty gear is a no brainer

buying from them can also be better.


sending a chinese purchased item from bitmain  that is under warranty with bitmain  to bitmainwarranty  is a guess as to if you are better off.

sending 1 board to china is about 100 bucks  you have to declare it at 45 dollars so lost stolen or damaged you are fucked

sending 1 board to colorado is about 18 usd if you are in usa and send it in a medium flat rate box with insurance for 300


repairs will be 150 to 175 + 25 shipping back.   so you are out around 190 -225  sometimes they are fast sometimes they are slow

so china repair  you are out about 115-135 and 3 -4 weeks   with a possible full loss of board

usa repair you are out about 190-225  and 1 to 3 weeks   with board insured for 300.

pick your poison basically.

Is bitmain warranty official warranty? As it sounds to me like they just use the name.
