Tried to update b12 to 11-25 firmware and the spinning wheel never stopped. After reboot miner is on the same old firmware.
Maybe I did not have enough patience? It is a 38.8mb file and I have to upload it to hosting (who knows what the speed is).
Did anybody had to wait more than a couple of min?
Additionally, does new firmware reduce chip temp a little? I have one miner that has PCB at 57-62, but chip is at 92-95.

It reduces it yes,
Stops the spin up as well.
It can take 10 or 15 to update, rebooting it while in an upgrade is a really good way to brick a machine.. you got lucky.

I don't think that update even started...wheel was spinning with a message: contacting ....
On S7 all updates took a minute or two. if miner was actually updating the soft, I would not reboot, but i checked on another pane and it was mining. Not sure that it would even take an update. Will try tomorrow and wait for 20min and see what happens.

So my batch 21 13.5 s9 purchased from Bitmain Colorado 5 Nov was actually getting pretty decent numbers, took a look at it one morning and pow, one board not hashing…power down/up multiple times etc etc .. no change, contacted Colorado, sent them the appropriate screen shots, they offered an exchange of the entire unit, bundled it up and shipped it off yesterday. I don’t recall reading anyone else exchanging an entire unit, could this be the beginnings of EXCELLENT customer service? Huh

Are you referring to bitmain warranty?
I've heard they are good.

I believe so...

The latest firmware.. Or the last few?
Have you set the Freq for autotune on install, so you could downclock an s9, but would need to reflash the FW every time you want to chnge Freq.
As it can only be done on initial install.

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

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

Thanks. Interesting...my autotuning 11th (not sure re batch #) unit has one fan at 3800 and second at 2080 with chip temp in 70iesC.
11.85 Th units (B10 and 12) have chip temp at 80-90C. Seem to be OK too. Did anybody observe any improvement in earlier (B1-12) batches with recent firmware?

Maybe, i don't even need an update, but not sure.

I've upgraded both my S9's without issues. Fan speed does seem better and more stable. For what it's worth these are batch 13 units.

Got it, thanks.

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.

Thanks for the reply numnutz. That's what prompted the question to be honest Wink

just thought I'd ask here than search the sea of google for a specific answer Cheesy

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

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.

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!

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.

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 )
