Does not look like an auto tune miner. No way it would have the exact same freq on each board.
I'm running nov8 on a 11.83th seems to run great but all the board freqs are the same.
Non autotune

Ah okay, but you find it isn't rampin as hard? at least that's a step in the right direction.

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
That's awesome, so does it allow fan tweaking or tweaking of the Hastrate?
Nope :\ At least not through the web UI and I haven't the time to poke through the config files and see where that's being handled now.

So Running the S9 on only two boards.
Right now I'm getting 626 and 626 frequency, very balanced.
The miner is showing 8.8TH Avg
But slush pool is reporting only at 7.8
Nice, loss of a whole Terrahash to the interwebs.
There a better mining pool to use?

typically 7.8 to 8.8 difference in your example is just noise (luck affects). it should fluctuate and sometimes be higher than 8.8 and sometimes lower while getting close to what you see on the miner in the longer average.
Also, check your latency.

There should be a way,
Someone needs to build a controller board to fake the fans response lol.
I'd buy that, But I'm also attacking ducting to mine to pump it into my furnace, But now I'll pick up a 4 inch duct fan to pull full speed, it should increase air flow dramatically.

We should be able to stick an extra fan at the back controlled by a rheostat to suck the heat out at a steady pace.
I would think two cheap quiet pwm fans could trick the controller
then just send 11 volts at the oem fans

Are the hashboards different between the old and new or just the controller/beagle? November 22, 2016, 05:10:54 PM

I got the same problems here, and just a look at the frequencies and temperatures of the boards tells me, that the large differences of frequencies over the boards is the cause of the problem of the fan, so being able to manually adjust fan would be the place wrong place to change something right now. (imo) And keep in mind that the card with the highest temp defines the fan rpm.
(Maybe large difference in temps causes a problem for the control loop of the fan speed)
Just look at freqs and temps in previous post
IMO. An even distribution of frequencies and thereby hashing power over the cards would help much more. It would decrease the chance of failure of cards with high frequency ==> high temps, and would most probably decrease the strong modulation of fan speeds. Be it cause by cycling of the mining process, or wrong interpretation of temperature by the fan speed control loop.

Looking at the miner stats the following was noted for one miner (the other problematic is similar).
1 card seems to do fine freq. 533MHz and temp of 91C. (slightly high)
1 card seems pretty low in freq. 420MHz and temp of 72C. (pretty low)
1 card seems to be quite high freq. 578MHz and a high temp of 102. (very high)
(I can upload screenshots if needed)

okay the card with freq 420 should be detached you would then have a 533 card with a 578 card the spread would only be 45 mz and fans would be stable.
merely a guess.

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

Honestly the fans on this thing are stupid, I can whisper to someone beside it one minute, and the next minute you gotta yell.
Why not find a bloody balance instead of on off?

The answer from Bitmain is that it must have this behavior due to engineering issues, "at the chip level." Basically, Bitmain has the temperatures rise high and fall on purpose, and they believe this will reduce the number of failed units. I imagine it also has the side effect of boosting their R4 sales as home miners won't be able to run S9s with this firmware.
Bitmain... How about some sort of coupon or hand out for the people who bought an S9 not knowing you switched the firmware to be unusable for home miners?

Batch 16 is when the autotune was introduced so any after that are autotune only.As I've said earlier on here IMHO Bitmain forced autotune boost the # of chips they can actually use instead of scrapping under performers. I have a batch 18 with wildly different speeds per-board but in total the miner runs at advertised 11 TH/s. Barely. My guess is they stuff the boards then test to get speed ranges for binning. After that they pick combinations of fast/slow boards to make the miner reach target speed.
ref that b18 miner to the b23 I just got -- on this newest one all boards are running 649.7 to 649.9 MHz to produce 14.129 THs. Obviously the b23 boards were cherry-picked for them.
November 22, 2016, 11:29:10 AM
The fan thing and the freq are related as the fan rpm is adjusted to the highest temp of the 3 boards.
I understand that, But they dial right down, nearly off. than crank back up to make turbine speed.
This is why the damn thing is so noisy, if it idled at 80% or so, it wouldn't need to crank up nearly as often, keeping noise down and temp spikes down. The fluctuating temp/speed is annoying.
Check whether your miner is actually restarting, when it cranks down. Or maybe part of the mining process. Am looking at this atm myself. This would explain it a bit.
In theory, when the miner would be constantly running, and one of the cards has a very high temperature, the fan should be running constantly high. Remark here, cranking the fan down manually (if it would be possible) to 80% would probably cause the high temp card to overheat & break for sure. Better would be to have all cards in same frequency range, so all cards have roughly same temperature range, then the automatic adjustment of the fan would work nicely (and probably at lot less noisy).
No not setting a Max, a Min.
I can hear it, and it doesn't turn off, it spins up, then dies right down, then spins back up a little later.
Miner keeps hasing away constantly.
I'd like to see the minimum speed stay higher, maybe it wouldn't kick into turbine mode so often.

Yes did try it, same problem, and the one time frequency settings only work for miners before the auto-adjustment miner generation of S9s. Mentioned somewhere on this post before too
