I like when donkeys feel the need to announce that they are "ignoring" me, the irony makes me giggle. 

How about the eDonkeys?

Go haunt some other thread. You are wasting our time.

Ignored.

Yeah, that was my point.     Thanks for the reply.

I had a 13THs S9 loose 1 hashboard.  Did reset, update...to no avail.  Notified Bitmain and they told me that I would have to send the ENTIRE S9 back to them in China.  What are your thoughts on this in comparison to sending the unit to BitmainWarranty(Denver)?

[numnutz2009]

...bitmain already gave us freq control....fan control is there as well you just have to compile the firmware yourself after altering the code to suite your needs...

That was the case long before you, or anyone else, even began to cry on here about them "taking it away". It's funny to watch you talk yourself in nonsensical circles.


Edit:
OK, so here's the real question:

Did this non-sourced, since you "cant read chinese[sic] so the name on the email is unknown", "engineer" tell you that Bitmain will break from it's long-standing policy and continue to uphold the warranty on any S9 that you "compile the firmware yourself after altering the code to suite[sic] your needs"?  

sorry for the delay in replying....i dont feel the need to take time out of my weekends to reply to trolls so i like to wait until im back in the office and have a few free minutes to respond to your nonsense.

the email says his name is "kai". that is part of the actual email address. the name on the email is in Chinese and like i have said before i only speak english so i cant read or even come close to understanding what the characters spell out so i wont bother trying to figure that out. The guy told me we are welcome to make the firmware ourselves using the source code posted. he didnt say it will void anything but i dont see it killing your warranty IF you use it the correct way. this isnt there to lower the fan speed. i even specifically told him i have 0 interest in lowering the speed of the fans. i only want to set them at a constant FASTER speed so the miner runs cooler and the fans dont whirl up and down up and down every few seconds.

I like how you keep trying to pick apart what i have posted. you shouldnt read between the lines so much though because im pretty open honest and blunt about everything i say. My question to you is how does running the miners at a lower temp somehow cause the miner to fail?? i know sub freezing temps can be bad for electronics not make to operate at those temps but we arent talking about icy conditions here....we are talking about typical ac unit temps of about 60-70 degrees F. do you think ramping the temps to 100 degrees c and holding them there is better for the board/components/chips?? its this simple fact alone that tells me you arent familiar with hardware like your claiming you are. i work on electronics daily day in and day out and in all the years i have run my business i havent ever seen anyone that thinks running machines at higher temps and harder is better for said machine. not one single time. even people here in this very same forum in this very same thread posted their concerns for the temps of these miners and that is coming from actual hardware developers....people that have made miners themselves and know more about the components being used then you or i do and yet you still fight it as if they are complete morons and know nothing about what they have spent probably hundreds of hours if not more tinkering with. your ego is far too large for one man.

of course bitmain warranty fixes boards for a premium. hell i highly doubt they "fix" boards at all. other posts i have seen showed entirely new boards being sent back to customers as replacements not the board they originally sent in but i havent dealt with them so i cant speak from experience there. what i can say for sure is no business does this sort of thing for free....they have to make money to pay the bills so of course they repair stuff at a premium so quoting that like you found the hold grail of evidence is completely moronic and its hard to even come up with words to describe how stupid that makes you look in general. but yet again your a sensitive guy that cant accept or admit when he has been beaten so by all means keep graspin at those staws my friend.

....people that have made miners themselves and know more about the components being used then you or i do and yet you still fight it as if they are complete morons and know nothing about what they have spent probably hundreds of hours if not more tinkering with...

Well, the 1st part of that belies your entire belief system on what Bitmain should/shouldn't do with programmatically controlling fan speeds, and as for the 2nd, kindly link me to a single post (in this thread) where a single person has given a single fact-based reason (as in with actual data to support the conclusion that programmatically controlling fan speeds is bad/wrongly-configured on a large scale) as to why they believe Bitmain is erroneous in programmatically controlling fan speeds....

lol if u think im searchin through 200 pages of replies you have clearly lost your damn mind. the second part is dont twist my words....i didnt say bitmain was wrong to control fan speeds....what i said was running the miners at higher temps does not benefit the board chips or other components on the board at all. its a known fact...heat kills electronics so to assume otherwise is silly. i think your problem is you dont like to directly quote people. you rather read what they say and spew out things that are completely different than what was said in the first place lol. im still waiting for an explaination about how running the miners harder and hotter is the best option for them....not to mention a comment to every other part i commented on but when you have no response you tend to switch to a new topic which just so happens to come right after you twist the words of previous posts around lol. if your still unable to respond to things i can and will break down my replies to 1 topic at a time so your brain doesnt get overloaded. either way is fine with me buddy.

i should also ask what hardware/software experience do u have?? u havent answered anything so far....you just reply with more and more questions even after people (including me) took the time to reply answering you so do u feel like your somehow better than everyone else? that you dont have to answer anything but yet you demand answers to your questions? these simple facts are what tells me and everyone else that your a troll and that your posts dont benefit the community one bit. honestly you should be banned from this thread all together for your pure ignorance but i dont make that choice.

...[blablablibbidybla].

I love the fact that you cannot support your claims and then claim that you made no such claims. You entertain me.
Either:
Bitmain was wrong to control fan speeds (and you can factually support such a claim with data)
or
Everything you said was just meaningless trolling based on mere speculation.

You drivel on about how I should prove that "running the miners harder and hotter is the best option" while ignoring the 100, or so, times I've reiterated that the ROI is diminished at a far greater pace than any "improvements" seen by mere cgi file "underclocking" (never once have I questioned the validity of those, like Sidehack, that actually change things [including frequency and voltages] based on measured results). What good is a $1,200-1,800 miner that lasts 10 years and only produces a gross of $1,000 over the entire 10 year period?

Either present data to support your claim* or go back to your little troll-hole.



*surely someone with your level of certainty has charts with BTU output recordings to support your claim that manual fan speeds make the miners run "cooler" and more efficiently....

numnutz2009:

Not sure what you hope to accomplish by feeding the troll, but, on behalf of all who have it on ignore, can you please stop quoting it?

And as for the capitalisation of your sentences, I do understand your laziness around the concept, but I'd just like to remind you:


Dear people who type
in all lowercase,

We are the difference
between helping your
Uncle Jack off a horse
and helping your uncle
jack off a horse.

Sincerely,
Capital Letters.

Beautifully put, Biffa. You, sir, are a gentleman and a scholar.

...why they believe Bitmain is erroneous in programmatically controlling fan speeds....

Bro, haven't you been paying attention to everyone complaining about failure rates of the S9's ?

[fanatic26]

The problem with the S9 is not the fan speed. It is running the chips at such low voltages to get the gaudy efficiency numbers that they ride on the cusp of failure at all times. Hence why the T9 has less chips running at a higher voltage and is much more stable and less prone to failure.

True, after hours of pouring over the code, I've yet to understand the "logic" behind the reversal of SOP when it comes to voltages.

Wow 13TH for less than 0.5BTC now from Bitmain.  I might actually swap out my S7s for S9s.

But its summer, and my S7s can survive my 110F garage just fine when running 4.5TH (Batch 1/2, so higher chip count).

How are S9s with high ambient temps?  Can they be slightly underclocked to compensate?

Thanks for any info.

[fanatic26]

The S9/T9 are not as heat resistant as the S7s were. In my opinion they are pretty sensitive to the heat as they have to run the chips so hot by default.

Thanks for the info.  That is what I was afraid of.  Still curious what ambient temps people have tried/succeeded with!  Those farms in china run hot with just outside air and seem to be ok!

...Those farms in china run hot with just outside air and seem to be ok!

You can just about bet money that they all run with ambient temps under 80F.

Looks like you can purchase an S9 from bitmain.com, but they are shipping more than a month out.

[taserz]

Should I buy 10 of these or 10 or the T9. Planning on building my first farm. Want to start it in my house and once I figured it out and it generates enough cash flow to rent a place out for it and scale it up.
