Topic: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order - page 313. (Read 531298 times)

but do you have another non bitmain psu that you can connect up to the miners or just to the controller to see if they power on. im not saying their monster psu's are bad or anything i just don't have 220v so i never used them but maybe the controller doesn't like the bitmain psu sorta like one of my s7's didn't like my evga g2 1300w psu while all my other miners worked fine with it. its just an option.

those chips temps are wayyyy too high my friend. your running some dangerous numbers. they should never go much higher than 70 degrees c at the chip and each day it runs like that it loses a little more life until it finally dies. if posible i would try fixing this sooner rather than later. i dont want your hardware throwin out that magic smoke.

first how m i supposed to know where the kid lives?? silly boy think before you speak

second he wasn't clear that's why i asked. there's no reason to assume ne one has 220v power and since idk him personally i didn't want to assume pay attention

third you obviously don't mine much. those that have would know psu issues do come up. for example some times a power supply wont power on one miner but it will work on another one of the same model. i had this happen with 2 s7's i have. the psu would work on every other miner i had except one s7. i tried like 5 s7's and all worked great except for one miner. i had to use a dps-1200fb that i modded as the supply for the controller. the psu that wouldn't power on that single miner was an evga g2 1300w psu so ik the psu was more than beefy enough to power on the controller besides if it wasn't all the other miners wouldn't have powered on either. so before you go runnin ur mouth kid ask. don't say my comments r useless because frankly ur ignorant negative comments don't help at all. i was at least offering a suggestion to him and others like him. what did u provide?? absolutely nothin! so take ur bull elsewhere please or be more polite to your fellow community.

maybe s9's are just arriving dead. i wasn't stupid enough to buy s9's at the current price and risk tens of thousands of dollars until things had a better roi but that doesn't mean i cant try and help people that need it which is more than u can say based on that ignorant reply. 

Worse yet  they disrespect many good honest people. 

Such as CK ,Kano, myself and sidehack.

But with the solar array  maxing at 11kwatts and only bitmaintech selling .1 or .11 watt gear I purchased 4 units.

Even if we do 50th at 5.5 kwatts  rather then  56 th at 5.5 kwatts.

  I need to have the more efficient gear. as the array's cost is far more then the gear's cost.

Ok, my S9 start working a bit better.

Most important thing was set fan manualy at 90%. After this at 650Mhz get 13TH+ but with quite a lot HW errors (0,0015%). After lower frequency to 625Mh HW drop to 0.0003% and speed stabilized at 13,1TH.
Strange thing is that miner need few restarts to hashig properly, sometimes 1 board hang at 3TH  and dont want speed up.

What I'm not seeing is what are the ambient temps these are runnin in.  With just some high volume fans I'm able to cool gpu fine 100f outside temps.  Just have to move a great volume of air.  With that said. My s4 run at 55c with over clock to 218.75. Need to know if it's even possible to run these at all. And another quick question.  Phil I know you like helping the community and I appreciate your knowledge.  What I'm trying to figure out is why bitmain isn't answering all the questions.  Why do they leave it up to you and a couple others.  Why don't they participate more?

I have to tend to agree here   Be nice for some competition anyway.  To the avg user looks like bitmain sells to us the first test batches until all bugs are worked out.  Leaving that work for us for free no less.  It's like open source only they get all the benefits of the expertise from many of the community.  Then they sell it back to us??  It's a win win for them.  See bitmain has you all between a rock and a hard place.  They know you can't buy hw anywhere else.  They know they can send you junk and there is nothing they have to do about it.  And better yet are you going to waste the time to sue them to make it right.  When you keep rewarding bad behavior then why would they change a thing?

drop to 643 test for about 3 hours
drop to 637 test for about 3 hours
drop to 631 test for about 3 hours
drop to 625 test for about 3 hours
drop to 618 test for about 3 hours
drop to 612 test for about 3 hours
drop to 606 test for about 3 hours
drop to 600 test for about 3 hours
your machine reminds me of my  bad batch 1 s-7

finally got good numbers in the 550 range vs the stock 600

right now  in a hotter space then most I am running 1 s-9 at 587  and 1 s-9 at 625

As always Bitmain bad quality first batch.

I wonder when is the Avalon 7 is gonna be released.

I will buy the S9 after halving and Bitmain sorts out all issues

Looks like you should lower it to 600..

No Quality Management or just give a fuck about customers

Im planning to try out lower freq on 2 of them today even they are all running at very cool temperatures. 80C on Chips.
I just do not understand why 2 are just dead….  No light no nothing. Tried 3 different Bitmain 1600 psu's on them and they just do not react at all…

You got it right Tupsu,
All New Bitmains 1600 Watt psu's and 220V. Got 100+ Bitmain miners and have never had so many problems with a lot like these 5 pcs.
2 of them are just completely dead… no light no nothing.

Don't have any thermometer at hand right now but should be around 22-23°C.

Sometimes a slight  freq down-clock will improve  numbers :

try 643.75 for a day and compare.
try 637.50 for a day and compare.


the s-3's   and I had a lot   sometimes the 343.75 or the 337.5 were better then the 350 settings

In a data datacenter I'm getting 13.55 TH/s average for one day as read by the pool.
13.66 TH/s on the miner (avg). Errors are at 0.003.   650M.
Temps are 62 PCB and 88 chips.
As good as it will get I imagine.

what is the ambient temperature in the room?  I suspect that getting 14.0 th will not happen  unless room is 70 f  or 21.c

and that board is not sick  61c  and 93c are fine

Yes. I used a few more friend's account. Miners from my own account  I received yesterday. The rest should be today.
I bought yet only 2 pieces more
1 x Batch2
1 x Batch3

Here's stats after 12h of mining my S9. Hashrate far below 14TH. At 650MHz hashrate was below 12TH and definitely ailing last board. Best hashrate got at 606.25MHz, 12,5Th @ 1310W from wall.

Buddy, Slush's has the BEST dashboard, but CKPool has the BEST profits.
