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

[not.you]

Has anybody had problems with low hash rate in one board with S9, batch 2?
That particular board hashes about 2.5-2.9Th/s.
I had this problem once before but it went away after few restarts.
Now I'm stuck with the one board performing at low level.

Ideas?

No x's are shown in ASIC status.
Firmware is original.
edit: I was able to fix this back to normal after all.
It required maybe like 30+ restarts.
What a strangely acting miner..

I have this exact problem with a batch 3.   I installed the low voltage firmware which seemed to help slightly (fewer restarts needed to get the 3rd board to hash normal speed) and I also downclocked which also helps in the same way.  But I still sometimes need 4 or 5 restarts to get it working right and even then that low hash board always hashes less than the other two.  This miner has been this way from the day I got it.  I have spent 20+ restarts trying to get it to hash normal at full freq before but I don't even try anymore.

This happened to me as well and I almost gave up on restarting the miner.
When I now finally got it back to the normal hash rate, I'm avoiding any restarts etc. with it.

edit: This is how it looks like for me at the moment. The problem was with chain#4 board and it is still hashing with little lower hash rate than the other two boards. The total hash rate is little under what it suppose to be (12.93Th/s).
(click for bigger picture)

Mine looks nearly identical except the freq is lower.  Top board has the highest hashrate, middle board is close to it but slightly less, and bottom board (which is also chain 4) is always atleast 100 GH/s less than the top board.  And that's what I get when I get a good boot which sometimes takes several reboots to achieve.

Hello.My hashboard arrived at Bitmain service, UPS says it was collected and signed by MR SUNG yesterday, 09.09.2016,
but on BITMAIN service ticket it is not updated as collected.Should I worry ?
I sent a mail to bitmain support regarding this

It takes sometimes up to a week for them to update it.

they update my ticket after a week with this


and send it to me
is that mean it repaired or replaced or what ?
they don't tell me anything

I got power supply warranty and replaced but they replaced with crap power supply (not new one) and the miner wont hashing. What a waste of effort (sending to HK cost $60 and getting back to pay duty $25). Better buy new power supply.

They generally will ship it back to you withing a few days, once they post that status on your account.

they shipped it to me
is than mean it fixed ?

says replaced so you should be getting a working board back.

can we install S9 550 to S9 600 default firmware?

I'd like to add that one thing to notice is that my miner had 2pcs V3 (version 3) hash boards and 1 piece V1 hash board.
The low hash rate -problem was with the V1 hash board.

lots of probs but still sold out heh ...

I know this questions was asked millions and millions of times, but I need help with my farm.
The first one is about temperatures of course, on Bitmains official webpage I red that the chips shouldn't go above 115C, but I haven't found anywhere anything saying that some temperatures are normal some are fatal, can you please help me with this ?
first pic shows the miner on frequency 500 and the second on 600. What is the optimal temperature to mine on frequency 600 ?
I.

II.


And the last question is about one of my S9s. All three boards are working properly only on frequency 100 (I checked almost every frequency to 600). When I change freq to 100 and above miner status shows this:

If I can fix it myself that would be great, if not I have to send the faulty board back (if it is faulty) to Bitmain warranty.

Above  I would try fans manual 90%  and freq 575

temps of 65-95 are pretty good



BELOW looks to be a bad board

you could switch the hashboard to controller conectector. to see if the connector cable is an issue.

you could connect just the bad board and the controller to the psu to see if the psu is weak

@mettalmag,

Cooler the better

Also, if you noticed, no drop into pool1 or pool2 = good internet connection be recommended

[philipma1957]

Yeah.  I can't buy more unless I get a better warranty.

Let me preface this by saying I have a lot of respect for your contributions to this community.

Your musings on rationalizing purchases of Bitmain product, as they struggle with warranty and QC issues, leads me to simply ask "Why not try buying and holding BTC for a change ?"

I do that.

I have purchased 3 coins over the last week.
I have some coins I am holding already.
I could buy 3 more coins and use them to hold rather then get one more s9.

I kind of feel I need to get one more s9 and I am hoping for a price spike on the three coins I just purchased to shift up a bit in price. Kind of just a bit twitchy .

The 16nm curse strikes again. Yesterday totally lost one board on a s9 batch-11 I got a few weeks ago -- no lil' red light on the hash board so means no Vcore turning on

BitmainWarranty emailed getting my loony batch-1 board and are looking at it. Looks like another board going to be headed their way even though the miner IS in warranty, even with repair cost is faster/prolly cheaper than sending it to Hong Kong.

I've heard about the loosely attached inductor in some hash boards that makes the board not to show up, but I guess that this is not that kind of a case?

1st I've heard of that and good to know. I'll find out tomorrow when I pull the board out during lunch.
In the meantime I put one of my trusty spare undervolted s7's online in my office to make up for some of the lost hash.

Yikes! Ja that will be pretty obvious and hopefully an easy fix to solder properly.

I take it Bitmain and/or whomever they contract for PCB assembly never heard of AOI systems to catch this very obvious kind of thing?

[MyRig]

Item like this, if you receive it, USA/RU/UA locations will not charge you to solder them back on. (do request shipping fee be paid both way tho...)

If I see this on my board I have a 75w iron just for this kind of thing so will be an easy repair for me to do

Any um' 'side effects' of the bad Vcore power to be aware of that this kind of fault could produce as in possible damage to the ASIC's?

one of my s-9's went off line today.

I am going to check on it tomorrow it appears to be the entire unit.

@ bitmainwarranty

I am looking to order 1 psu from your store and maybe a controller after I check on tues I will get back.

what do I pick for shipping?


 Next Day Air Saver (UPS): $82.12
 2nd Day Air (UPS): $54.01
 3 Day Select (UPS): $42.81
 Ground (UPS): $31.34    >>>>>>>> or must I pick this one?
 Product Shipping: $15.00 >>>>>>>  this is cheap how long to NJ

Product Shipping: $15.00 >>>>>>>  this is cheap how long to NJ

Cheapest one if you are not in a hurry.  Its depends on the day, may go out via USPS Percel Post, Priority Mail or UPS, whichever the warehouse guys are able to pick/pack the latest.

UPS Ground option be UPS Ground but the last option is a mystery shipping.  The slowest speed be shipping from Denver, Colorado to your destination via Parcel Post via USPS on next business day shipout. 

UPS the best option for the warehouse as there is a daily pickup by the UPS and staffs know the cut off time to meet.

one of my both B12 get all 3 ASIC's XXX and reboot solve it
why this happen ?
my temp less than 82 all the time and freq lowered to 500

Probably USPS @ $15 figure at fastest 3 business days (if using Priority boxes),slowest 8 days.I do alot of ebay & use USPS most often,just around the corner & boxes are free  

Just don't do DHL,they suck azz here in the US
