How about your temperatures. I flashed the fixed 650 and my temp started to raise to 109 C. I was going mad, thought I had bricked my device. Anyway, I didn't because then I flashed the auto frequency and it started to act normal. Anyway, with those temps I ain't gonna do it. Someone a suggestion? (cause otherwise I have to stop mining, cause for me the electrics are more expensive than my incomes...)

Wait til wintertime and heat the house with your miner. Save some money on the heating bill.

Hints. Saved money is earned money.  (Snake in the wild..)

Umm, guys?
I just started to try to overclock my S9s from different batches.
On one 14TH model from march or so I applied the fixed frequency firmware and ramped the frequency now up to 750 MHz so far. No significant HW errors, hashrate is over 16.2 TH at 85°C chip temperature.
Are the chips really capable to do so much more?

Interesting: Tried a second S9 from the same batch. On the fixed frequency firmware temps go up to 105° C on default 650 MHz. Flashing back the autotune
Edit: 3 of 4 S9 14TH get over 100° after flashing fixed freq. firmware. Any idea why? One even showed 132°. I dont know if that is correct at all.
I did not wait and stopped the miner by deleting the pools and flashed the autotune FW again.

I heard that someone say that downgrading to november firmware can fix some issue like wrong temp reading and other miner firmware issues.

The bad thing on overclocking miner without proper air circulation or cooling device your miner can exceeds higher temp that can lead to higher temp protection and also, chips or the hashing  board may burn and damage.

Did you try this method https://bitcointalk.org/index.php?topic=2690140.0
you can modify the fan speed of autotune firmware then set it to higher speed it may help to cool down the miner.

Yeah, I know that. But given the limited usage time of the miners, you should squeeze out any hash as long as they are profitable.

There is the November firmware which should be the recent: Antminer-S9-all-201711171757-autofreq-user-Update2UBI-NF.tar.gz
And I am usind this one from may for the two miners that run 16TH: Antminer-S9-all-201705031838-650M-user-Update2UBI-NF.tar.gz

Are there any else?

I found out that the two S9 14TH that were ordered on 24th of march are able to run at 85° @ 16,1 TH.
The four S9 that were ordered on 5th of april are not working properly with the fixed frequecy firmware.
Can anybody confirm?

The two overcloced seem fine. Why do you suspect that the readings are wrong?

Because if you go into the kernel log it says only detect temp upto 82.. that means it could be at 110 and its only detecting up to 82

Why does it only detect temps up to 82°? Is it only the specific firmware with the specific miners? Because not all behave the same.
Also: Why does the temperature go over 100° on stock settings from the fixed firmware?

edit:
seems fine to me:

Code:
do read temp on Chain[5]
Chain[5] Chip[62] TempTypeID=55 middle offset=31
Chain[5] Chip[62] local Temp=79
Chain[5] Chip[62] middle Temp=92
Done read temp on Chain[5]
do read temp on Chain[6]
Chain[6] Chip[62] TempTypeID=55 middle offset=30
Chain[6] Chip[62] local Temp=74
Chain[6] Chip[62] middle Temp=88
Done read temp on Chain[6]
do read temp on Chain[7]
Chain[7] Chip[62] TempTypeID=55 middle offset=29
Chain[7] Chip[62] local Temp=77
Chain[7] Chip[62] middle Temp=90
Done read temp on Chain[7]
set FAN speed according to: temp_highest=92 temp_top1[PWM_T]=92 temp_top1[TEMP_POS_LOCAL]=79 temp_change=4 fix_fan_steps=2
set full FAN speed...
FAN PWM: 100
read_temp_func Done!

I don't know what exactly the filename of november batch firmware but someone said this filename Antminer-S9-all-201711171757-autofreq-user-Update2UBI-NF.tar.gz) is the november batch firmware and I already tried this firmware the temp is lower than the other firmware but I experienced weird issue it detects a bad chip then turn the frequency fixed to 400 reflashing and restoring to default factory settings solved this issue so if you going to try this firmware and experience some issue you reflashing and restoring them to factory default may solve the issue.

Also, what I notice about this firmware the hashrate is lower than the firmware you run on your two miners.

I already tried a factory reset after flashing. Unfortunately this did not fix the high temperatures.
I dont know how the other people manage it or if they also face this problem.

If your miner running at 16 TH/s your miner will increase its temperature above 80 degrees I advice you to reduce the frequency but expect for hash rate drop, check this guide https://bitcointalk.org/index.php?topic=3239820.0

Yes, I know that. But as I said, some miners of older batches work fine and stay below 90° even with 725 MHz. Some miners rise at stock 650MHz over 100°. So I suppose that the guide does not work for all hardware versions of S9.

Have you realized that the autotune november version is more power efficient than the fixed version one?

For the same amount of hash rate, power drawn of fixed frequency version is higher.

I believe the autotune and the new 14TH versions reduce the PIC voltage to the absolute minimum necessary level to improve performance. And sometimes some ASIC chips fail to communicate and drop from the chain.

Is there any other Antminer images built to test with differente PIC voltages?

Regards.

I didn't notice it yet if there is different power draw from any firmware but I think it is depends on frequency if your miner set to higher freq it should consume more power than lower frequency.

I don't know if there is some images with different Voltages but you can try the other firmware from bitmain here https://service.bitmain.com/support/download

Can anyone confirm, that there are autotune miners from the newer batches, that are not able to work with the fixed frequency firmware? As I said, they report high temperatures, even at stock frequencies.
Or is there a way to overclock them? I did not find anything.

yes they will work on fixed freq.. i have many of them but i do prefer auto tune unless you live in a cold place

Ok, but what temperatures are reported? Mine went over 100° with the newer batches and i was a bit scared. Or are the readings wrong?

If them temps are showing over 100 they are correct.. if they are showing 80/82 ish they are incorrect.

Ok, but I dont understand: Why should the miner be 105°C hot with stock 650 MHz on fixes frequency firmware and on autotune on 650 MHz only 85°C?

if you listen to how the miner revs up, the fans run much slower on the FF650 firmware, but on stock 650FF 105 temp seems very high to me.. if you were operating at 15TH then i would say 105 is expected, but that is high for stock setings, whats your ambient room starting temp?.. do you have a cool air flow into the miners?

Ambient is between 20 and 30°C depending on daytime. No Aircondition.
Are all the fixed frequency models running hotter?

From my findings, and i work full time with these machines.. i found that the FF firmware, the fans seem to run a little slower, roughly say on autoFreq at 78+ the fans run at 5800/6000 where on the FF650 the fans seem to run at approx 4600rpm.. hence quieter, but that bit hotter..so the autoFreq i feel is for a cooler ambient temperature, i am in a location where my ambiant is the same as yours, i am on autofreq now, but when the season changes il load up FF650 and bring the freq up to sat 725/750.. get that bit more hash power but keeping the units cool at the same time, but in this heat that we have currently in the uk i am staying on autofreq.
hope that helps. J Smiley

Ok, that was helpful, thanks!

So you think its not some kind of incompatibility that causes the hashboards to just overheat.
