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

[NotFuzzyWarm]

19th nov firmware is the best one
stable fan speed and low temp

is this the upgrade for ALL batches or only some?
they lost some english-speaking engineer because what is written there is difficult to fully comprehend. Too much jargon.
At least, I am not sure that I got it.
It does have -all- marking, but what is autofreq-user?
I got two different 11.85th (summer) and 11th (fall) batches.
Are both of them autofreq or only later 11th?

Autotune started with Batches 16 & 17. I got a 17 and had verification from a batch 16 user his was the same. I'd have to look back but think it was late Sept for those?

Look at the system info. Batch 16 and later will report BMminer v2.0.0, also look at the controller. I think 16/17 were the first with no BeagleBone.

Somehow I was unable to find this??? Do you have a link?
Thank you

New firmware did have minimal improvement in case of our S9-B22 that the fans run a bit more stable (at least for the 2 of 3 still S9s running of the ones we got 3days ago, 1 miner already lost and on its way to Bitmain, return shipping at own costs). However, the improvement is not much, we still have strong modulations in fan speed. Nonetheless, it doesn't remove the problem with unequal frequency distributions over the 3 boards in a single miner caused by the auto-tune firmware (or maybe boards, or maybe greediness) which is the main issue IMHO with these miners that is causing increased failure rates of cards/boards of the miners.

I don't look forward to warranty work, I'm unsure how to claim the taxes on the returned part, fedex dinged me $300 when it came in the first time, if those SOB's try it on a warrantied machine I may have to stab someone

I will try that new firmware tonight.
But when I look at my miner control panel, one of my boards reads 99, and the others are high 80s. Seems to warm to me. or warmer then I would like.
Yet with no control WTF am I supposed to do about it?

[imnotarobot]

So I'll deal with it until their crap warranty is up, then let me adjust my own fans, this is annoying as hell lol.
In it's own room in the basement, and I can hear it scream through the floors

install some fiberglass insulation to the underside of the floor and that will help dissipate the noise level.

That is exactly my point. Imo the high temperature of cards is the major problem. One of the cards in 1 of the 2 miners still running showed a temperature of roughly 100C while running with roughly 580 MHz, another cards in the same miner is running at roughly 70C with 420MHz. The card with T=100C is imo too hot, but as user without any options to reduce the frequency, this is nothing I could change with the auto-tune firmware.

[polymer_city]

Does anyone have the previous firmware pls?
I did a fresh install and lost the backup!

Not being able to set the fans is ridiculous.

I want 450 with 35% fans... but no... Well done bitmain!


Is there a way to set Freq to 450 range?

[takagari]

Read the last two pages we discussed this, not an option yet, some work arounds, older FW will help, it's linked above.

Have been running this for half an hour,
Thus far the fans are staying higher speed, 3400 and 4000 rpm,
The 4k one seems to be going just fast enough to scream a little. Which is to bad, would like to get rid of the squeel, the howl I can live with.
But the temps are sitting just bellow the 90s, where as before one of my cards was sitting at 100 constantly.

Putting the S9 back to this firmware does help the fans issue!!

[mamiakimo]

today my first S9 that i ordered in 13 Jul stop working on the latest firmware (19th Nov)
i flashed this firmware again without success so i installed old one (Antminer-S9-201607131442-12.92T-600M-security.tar)
i found 2 boards only work and i lost one board
when i checked my machine to see which one i lost i found it's the same board that i lost it from 2 months and they replaced it to my under Warranty
this board sent to me on 7th Sep
is it still under Warranty ( my machine is not )

Oh so you just tie in the one wire. Is it simply a pot? Or is there more involved in that adjustment? I can't find the one you purchased any longer, but I'm still looking.
Thanks

The PWM signal is not analog (from a pot). It is digital Pulse Width Modulated signal, I think around 1kHz, that drives a switching circuit inside of the fan that handles the power side of the equation. The on-time vs off-time determines fans speed. Just to confuse the issues, there are 2 different schemes used... Most common one is no signal (always Lo) puts the fan at full speed in case the signal wire opens. Also seen is the reverse - no signal means slowest but usually not zero speed.

Query: What does the fan do with the blue wire disconnected? Full speed or slow?

yes when you unhook the pwm wire the fans will spin at 100% all the time.

and no a pot will not work to control the fan speeds. the device i linked has a pot on one side but the other side has the components that are controlled by the pot. without those components the pot would be useless in this situation.

4-wire PWM fan standard dictates the PWM driver have an open-collector output, which means it has to be pulled low for the fan to see "low" and floating means "high". Standard also states I believe 24KHz with about 4KHz of play to either side as within tolerance.

I've got an idea for a controller that wouldn't take more than about a day to put together, but it could be set to either a maximum or minimum PWM. It'd detect the controller's drive PWM and override it if it crossed threshold. Something like that would be useful for an undervolted miner or S7LN where when the miner first kicks on the fan pulls up to 100% and it's loud. Or it could give a lower threshold to limit the up-and-down throttling of the autotune miners.
Probably should have had something like this prototyped already. I figured out how to do the PWM detect and override like a month ago, just haven't gotten around to coding it.

I was just thinking of this as well.
A controller that monitors the low, and won't allow it to drop bellow a set value, possibly also can do the same for the high? would be nice to keep the fans just under that nice whistle, around 3700RPM, above that they seem to whistle.
I'd buy this, please if you do it let me know, I'll be the first in line!

Did anybody update to 11-25 firmware?
I know that people liked 11-19, but it is not available anymore.

Quick question regarding fans. If I were to change the fans out to a 3pin 120x38 fan and use a 3to4pin adaptor cable what issues would it cause? Would the fans run flat out as its only a 3pin fan?

firstly dont change the fan.

secondly yes the fan will run flat out because the controller isnt designed to control the fan speed via the output voltage...its designed to controll it via the pwm controller so the voltage being delivered will be a constant 12v and on a 3 wire fan that means running them at 100% all the time which isnt good for the fan at all. they r made to run at 100% but in short bursts not all the time. mmore than likely the 3 pin fan will not more enough air anyway unless its made to move the same amount of air as the current fans do.

in short dont swap the fans. read my post and sidehacks post about a pwm controller.

[gt_addict]

Thanks for the reply numnutz. That's what prompted the question to be honest just thought I'd ask here than search the sea of google for a specific answer  

Something as described above would be ideal for me to be honest.

I just upgraded one of my units.  It appears the resting fan speed was reduced from 4,440 to 4,320.

Hey dumb question here, but i just got my first S9. I'm wondering, do I have to manually connect it to a pool via IP reporter after every time I power it down? Can it not reconnect automatically to the pool after I turn the power back on??

Normally I wont power down much but if there's a power spike and it temp loses power, it would suck if I have to go manually hit the IP button

You won't have to recconect, it will keep your pool settings after a power cycle.
