I'm pretty pleased with the service of Bitmain Warranty in Denver, CO.

Even though the board they repaired for me didn't work properly after all (it keeps dropping to zero hash rate and shows a row of x's),
they handled fixing the situation very well.
They will send me a working hash board in exchange after I have sent (I just actually came back from the post office) the faulty board back for them.

I can definitely recommend them for fixing your miner.

And thank you Phil and the others who have shared previous experience with them.

I think this is rather about the amount to produce, gauging interest.

This is the second order in a row where they are giving a future shipping date. I know Chinese New Year is part of it but...

Do you think this will become standard? I mean, why not take our money ahead of time? The miner will devalue in the month wait and they can mine with it Tongue

'The right to privacy matters'

This has been corrected and the number is now 967 on both websites.
So if you order that march 1 unit be sure to check and see that the numbers match on hashnest and bitmain as they should .

Also if you purchased the s9 at the 917 rate ask for a refund of around 60 usd. I really would like to see and read if you got stuck and if they fix it.

as a heads up coinbase is quoting btc at 960 usd

bitmain is quoting btc at 917

thus you lose about 65 dollars if you use coinbase.

Hashnest has coins at 956

since hashnest and bitmain share the same website and are under the same umbrella it is really fucking bad that they do not match

Take a look

Hi,

I just realize that S9s are sold out. Any idea where to buy? or when is the next batch? I am going to buy 2 S9...

Thanks,

You didn't need to wait long - another 2 batches have been released with a ship date of 1st of March.

Thanks for the update....

I had a board repaired at the bitmainwarranty, but it still isn't working correctly.
It occassionally keeps dropping to zero hash rate and asic status shows a full row of x's.
Reboot fixes it again for a variable amount of time.

I've tried different communication port on the controller and the problematic board only moves to a different chain and the controller in functioning normally.

I'm keeping in touch with bitmainwarranty to find out a good solution, but as a back-up plan I was wondering if someone here would be familiar with a script for restarting the cgminer/bmminer in case of some of the boards dropping to a zero hash rate?

This is a 11.85Th/s 550M pre-autotune model.

Use Awesome miner and create a rule for the miner to restart or reboot whenever its rate drops below your trip point.

Works well, Awesome for me, especially with my under-volted s7's. When one gets cranky and drops a card I have the rule set to start CGminer again and the card comes back up. So far with s9's that works as well which is great considering the s9's -- especially the auto-tune ones -- don't like reboots...

Thanks, I'll consider this. I was wondering though if it could be some how wrote directly to the cgminer conf for example. (via ssh)

edit:
I tried now to swap one board with my another S9 and see if I get any new results, lets see...
edit2:
yep, same results as before, so it is indeed still a faulty hash board and other components are ok.

Bitmain is observing the Chinese New Year. Check again next week (roughly February 5th). You might be able to find a previously owned one for sale on the "For Sale" sub-forum:

I use Cryptoglance only for an at-a-glance view of how my miners are running at the pools. AFAIK it has not been updated in a while to support any vital miner control functions on the s9's on up...

'The right to privacy matters'

Yeah it would do just that.

I suppose I could just ship the dead board one in and wait for the fan to fully break on the newer unit.

I need to put all this into R4 section later. I am not doing anything until after Chinese New Years ends on Feb 3/4

So you only have the 2 r4's both have an issue both are under warranty.

Your goal was to swap the bad fan with the good fan. to be able to just send in 1 machine.

Yoshi said no can do . I think he misread what you were saying but I do understand him. As bad people may try to frankenstein units to rob them.

In your case both units are under warranty. So you would be saving them a lot on shipping. Sending two units to China for repairs in your case would be pretty dumb.

As you could put together one unit with a bad board and a bad fan and ship it for repairs it would save everyone on shipping.

It also would allow you to continue to mine with 7.5 th.

Yeah my problems are with R4's

Here is the r4 10-11 days old fan grinds but boards are good.

Here is the r4 51 days old fan is smooth but 1 board is bad.

@philipma1957.....

phil, phil, phil.....

now days, fan is serial numbered as well for warranty purpose!!! Its sad but we do see high number of attempts, purchase 1 unit after the old unit break, then attempt to claim warranty via recent purchase. That trick sadly worked in the past... we may be a slow learner but learned a lot

Quote

I would like to swap fans. And send the unit back with a bum fan and a bum board.

I think I will talk to Yoshi from bitmainwarranty in USA asking him if he would let me do this.

yeah and both are under warranty. one is about week old and fan sounds really nasty.

the other is about 45 days old. and has the dead board.

so as of now I have 3 of 4 boards mining. to do it the way you want for two units under warranty.

I need to ship both units back correct? lose 3 hashing boards for weeks. pay shipping for both units.

here are the orders both are under warranty.

the new order has a bad fan (noisy with a grinding sound) and both boards work.
the old order has a bad board and the fan works

both are in warranty.

I was only looking to save your company money. and to save me hashpower.
here are the orders. and these are the only r4's I have

This is 50 days old 1 dead board but fan is good

Ten days old fan sounds bad boards are good

Anybody knows where can I buy replacement fans? Bitmain page is sold until after Chinese New year.

For one, check Bitmain Warranty in CO. http://bitmainwarranty.com/ They carry them and being the USA they are open right now.

Thanks man.

Anybody else had problems with defective fans? I have a new miner that overheats. All I can see is one of the fans won't run above 1900 rpm.

Could it be some other problem besides the fan?

My newer unit has a fan that is very noisy .

My older unit has a fan that sounds sweet smooth etc. and it dropped a board a week ago.

I would like to swap fans. And send the unit back with a bum fan and a bum board.
