I understand that you are a fan of all things BMT, but what makes you to be an expert on S9? Tongue

1) I'm not a "fan".
2) Experience with ~1,000 units?

1% number could be accurate with regards to recent batches of autotuning 13.5Th machines, but initial batches (last summer, not autotuning) had up to 10% (or even a bit higher) board failure rate (within first couple of months) according to multiple sources, which was amply documented here and elsewhere.

Perhaps, most machines that you got were purchased during later part of 2016 or in 2017.

I have 51 Running. 4 have one bad board. They have run around 3 months.

Sorry to hear Undecided

This is a good example and closer to the truth.
7.8% failure rate in this case.

Doesn't look much promising. And a device making 30 TH/s will have the same profitability, if released in a year from now for $1600...

Any update on Antminer S10 release date and its expected hashrate?

Sure, any day now...: https://bitcointalksearch.org/topic/first-bitmain-antminer-s10-speculation-thread-probably-1489276 Roll Eyes

Bummer... You fill out the ticket and ship it. Put in the tracking# and shipping company used. Once they get it you will get an email.

Gotcha, thanks! I didnt know if it was one of those fill out the form, wait for RMA, and then ship it kind of things like most GPU MFG require. I appreciate your quick responses!

On a side note, i am very surprised i had PSU issues, this is the first time i've ever had a PSU issue... I've bought quite a few psus...

i wonder if they have a warranty sticker on the screws of the psu. does the fan spin freely when moved by hand?? if so maybe they didnt hook the wire up to the main board of the psu when assembling it. who knows. its probably best to send it in though if your located in the us.

I didn't even think about that, I just sent it off to California. On a side note, it looks like one of the S9's i just received a couple days ago needs to be sent off for service. One of the blades died. Not good Sad

Yeah the tracking number and shipping company used must be mentioned already in the repair ticket form, so they can process it smoothly.

Question,

I have a APW3++ PSU that arrived DOA, the cooling fan does not spin which causes the PSU to do a thermal shutdown. I submitted a repair ticket with BITMAIN, do i need to wait to receive some sort of approval or do i just fill out the ticket and send it off?

In summary, we have a better S9 in modification (from 12TH to 14TH) which have reducing the failure rate each batch, do we?

Genie is being a Bitmain fan again.
Based on my experience and what I've seen in this and other threads during a long time period, the failure rate is far greater than 1%.
I would like to see where the number less than one percent is based on.

... But based on the groundswell of negative reports on this forum, it certainly seems like the S9 has had more reliability problems than previous models...

Or, it could be that people aren't psychologically predisposed to seeking out random venues on the internet to gush about a random piece of hardware they purchased (but people are psychologically predisposed to seeking out random venues on the internet to bitch about a random piece of hardware they purchased).

I found out that so many post how their antminer S9 not working well, any opinion about it?
How many percentage to have "defect" one?

We don't have hard numbers. But based on the groundswell of negative reports on this forum, it certainly seems like the S9 has had more reliability problems than previous models.

I only bought a couple of S9s early on. One has a bad hashboard.

It's the first Bitmain hardware failure I've had since I started mining as a hobby. I had a couple of S3s, a Spondoolies SP20, and three S7s without a single failure.

I realize that my numbers are not statistically relevant. But from a personal and anecdotal perspective, the S9 has been less reliable.

That said, I still got to ROI with my S9s. Barely though. The board that crapped out happened about two weeks after that unit ROI'd.
