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

[wolfen]

Got two 13.5th today . They were on oct 25 firmware. Saw the nov 2 firmware and installed on one.
Boards ran hot, fan was at 20%. Temps were 108c. Rolled back to oct 27, temps cooler.
They do run quietly at 20% fan but those temps are too scary for me.
They still cycled the fan speed. No hwe.


Here is the link to s9 oct 27 autotune firmware

Good until 30 days no activity.

How are you doing 20% fan?

With autotune firmware  the fan speed is set automatically like the frequency.

@Sierra8561 If you scroll to the bottom of the kernel log the last 7 lines show the temps and fan speed.  If you refresh that page those 7 lines will refresh values so you can see what fan speed the autotune is selecting. 

I can tell by the fan rpms on the gui about how fast it is set. 2500 is about 30% 2000 is about 20%.
Thanks for the kernal log tip.

Thank you, I see the chip temps. It says Fan PWM: 10. What does that mean?

I would bet that it means 10%.  If I look at the bmminer.conf file on my older S9's where I have static fan speed the line says: "bitmain-fan-pwm" : "90", which in that case means it is set to 90%.

EDIT: Also just for the record I did try altering the bmminer.conf file on the autotune one to have the manual fan speed and set the speed (two different commands) and the settings are ignored.

I was kinda wondering that, but it sure seems low. I know seasons have changed and summer is over but going from 90% to 10 seems a bit much.

Edit: as a test I adjusted another S9 to 30% fan and was in the high 100's in just a minute or two. So I'm not sure what it means.

10% that is ffed up
I do have 90 day warranty from Denver so if they burn up I'm covered
Sucks you can't override with the conf file for the fan

The latest firmware is awful.

I agree, flashed back to the old. Which one is working best for people???

Same version for me.  It hits 100 (usually always on the same chain) and that's as high as it gets before fans kick up to full and bring it down.  Sounds like a jet taking off every few minutes but it's getting the job done.  Hashrate is slightly above the 13Th advertised.

Same here, best one I've tested.

I've got a couple S9s running.  One of the boards on one unit keeps slowing down to 2TH/s after a couple hours and needs a restart to be normal again.  Not sure what the issue is.  Is anyone else seeing this sort of behavior? 

[moe7865]

3 of my S9 batch 19 are only running at 11Th and some even 10Th.
Very strange problem. My machines are hosted in labrador so I'm waiting to hear back if its a down board or just a firmware issue.
Really hope its just firmware

I've had similar trouble with S9, batch 2 12.93Th/s.
Board 3 was performing low when compared to the two another boards.
This was with the stock frequency 600 Mhz.
I changed the frequency to 550 Mhz, then let it run for a while and get warm.
Board 3 instantly performs better with the 550 Mhz than with the 600 Mhz.
Then after a while I change the frequency back to 600 Mhz and it runs okay.
Not exactly about 12.93Th/s like it should be but about 12.6Th/s and that is the best it can do.
Any frequency past 600 Mhz is a problem for the board 3.

that one is new.



I finally went to the solar array to check on the last two s9's I have.

One works the other went to all x's

I set it from 606 to 525 so now   it is working ..  I am back to 13th + 11.5 th =24.5th


I have old firmware on 2 extra controllers and 1 spare board.  This may get more valuable  over time.

I need to look at this thread on repairs.  I did well with pencil mods on the s1's

@HaggsFIN   the thread above may help

I also lowered fans a lot to get the gear warmer.  80% to 45%

My batch 18 has a similar problem. main cause is that board 1 is only running at 486MHz while the best board, #3 or chain-8 runs 580MHz. The middle board is around 546 Mhz. Methinks I'll try the pencil mod on #1 to see if it can get up to speed.

A side note to this is that the B18 and probably 19 seems to skip most or all of the auto-tune checks when soft booted. Came up within a few minutes and all boards report the exact same settings.

Just FYI for anyone thinking about the pencil trick to increase voltage I already tried it on my autotune (B19) and it did nothing.  I did it on an older non-autotune one (B3) and it worked wonders.  But the autotune ignored it.  That makes sense though because the autotune is adjusting freq for each chip.  I tried it anyway since I have 2 boards getting 4700 and one board getting 3900 but as I say, it did nothing.

[sidehack]

Probably the PIC samples the voltage to calibrate the adjustment, so if it's off because of a resistor mod it'll just dial in the DPOT setting to where it wants to be instead of where you want it to be.

Damn, forgot about autotune playing with that. Brainfart...
Now to figure how else to get the weak card up to speed

[sidehack]

Cut the PIC out of the loop and hardwire the buck on high? Hack the PIC to a fixed voltage and hope the controller doesn't mind?

I've been around a while now, sort of. But what is the pencil trick?
