19th nov firmware is the best one

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

Here it is:

https://shop.bitmain.com/files/download/Antminer-S9-all-201611190345-autofreq-user.tar.gz

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!!

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

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! Sad

Is there a way to set Freq to 450 range?

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?

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.

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.

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.

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?
https://shop.bitmain.com/support.htm

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.

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?

ya no one seems to read my posts very much lol. i agree the auto tune feature isnt much of a feature. it runs boards too hard and i personally would want to control the speed. idc so much about raising it but i would at least like the aility to lower the speed but with the new firmware your unable to. my post was just to give some sort of solution to those that wanted to solve 1 of the 2 issues which is fan speed control. if it helps folks great if it doesnt great lol. at least this way they can try to get a handle on the high temps when running these auto tune miners.

I read your post, just didn't fully understand what you were getting at, It also seems like it may not be the best option, If we set them at one point and it at some point needs more, no way to get that.
A software solution that won't let them go lower then a certain speed, but still ramp up if needed would be ideal.
But I will look into those controllers.
Did they do a fine job of tricking the s9 into thinking it still had control?
As I understand it, the thing shuts down if it thinks the fans stopped running.

the 4th wire on the fan connector is the pwm wire. this is the wire the fan uses to control the fan speed. the adapter i sent allows you to control the fan speed of pwm fans. it cant handle high wattage loads thats why you would unhook the 4th wire (blue) from the fan connector and connect it to the 4th pin on thespeed controller i linked in my post. used a flathead screwdriver you can use the pot on the board to raise and lower the fan speed. i thought this was clear but wossry if this still isnt clear enough for you.

yes this method is not ideal and i even said a software method would be best but this is a solution. its to run the fans at a constant speed. you dont use this method to run them at the lowest posible speeds...this is to raise them up so the temps stay steady and dont run into the hundreds like the stock fan settings do. thats all this is good for.

Here's a video of them, caught it at high power, then up to high then essentially off lol

Okay I'll google for the Nov 19th firmware, unless someone has a link?

It balances the noise out a bit? that's great.

It amazes me how I have to look at it to see if it's even running one minute, and the next minute yell to hear myself lol

Looks like it is the hashboard that is the autotune piece. I received a replacement board and installed it on an older s9 12.93 that had the autotune software
already installed and the new board autotuned but the others did not. Thought I was losing it.
Nov 19 firmware looks good.

for those of you wandering if this is the auto tune version. This pic seems to be a stock 14TH model. so it will be set to hash at 650M frequency by the firmware.

Has anyone tried the firmware from 11-19? I'm giving it a shot on one machine right now. Curious how it is working for others?

Fan speed is much better handled for me - slight variations in speed, gently ramped, instead of the bang-bang controller in the previous autotune FWs.

Seeing much lower reported temps (~10C lower) but I haven't dug into whether that is just a cosmetic change or a change in setpoint for target temp.

Hashrate is good - 13.904avg over 3025 hours on a batch 1 set to 650MHz (theoretical speed 14.004):

Nice of you to jump in, and still be following the thread.
but please, can we discuss the elephant in the room? wtf is with these fans
They idle so low one minute, and the next minute my neighbors can hear them.
I have no issue with noisy miners, but this seems like it's just unrequired noise.
One minute they blast at 110% the next they are cruising at 25%. than boom back up again.
If they idled Higher, at 60% maybe? they would need to spike as often, and this would help with the noise greatly.

takagari - This is what I posted about re: the 19 Nov firmware. For me, this firmware stops the fan cycling and replaces it with much subtler changes in speed. Higher average speed over all, but barely perceptable speed changes.

It's a big improvement on my S9, which is a Batch 1 / 14TH/s as BitmainWarranty suggested.
