I never bother about Overclocking Autotune because mining has never been easy either as a beginner or an old-timer. We all mine in other to acquire bitcoin or ALT coins so we can either trade with them, HODL or invest. I never knew how easy it would be to make profits from Bitcoins until a high school friend introduced me to MMM Gobal and ever since then I have never had the need to check the price of bitcoins except I want to convert my coins into FIAT Money because either ways i still make profit from the investment. Now here is my invite to you:
Join millions of people around the world who makes 50% monthly or 25% in 2 weeks profits by investing in Bitcoin and other ALT coins. Its very easy, all you just do is Provide help and get help either in 2 weeks or 1 month, which ever you think is preferable for you. This is just the tip of the iceberg. When you are convinced you can thank me later. Finding it hard to believe? Well I was just like you........

Topic: How to Overclock Your Autotune Antminer S9 (Read 2823 times)
Hi there. As soon as I see it, this custom firmware thing is quite complicated. I read in several places that everywhere, unfortunately, put the dev fee down. Can I still download a modified software that does not include the dev fee? I just want to modify the TH \ s. Thanks again for your response.

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

Ok, that was helpful, thanks!
So you think its not some kind of incompatibility that causes the hashboards to just overheat.
Ambient is between 20 and 30°C depending on daytime. No Aircondition.
Are all the fixed frequency models running hotter?

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?

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

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?

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

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.

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.

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

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://bitcointalksearch.org/topic/how-to-overclock-your-autotune-antminer-s9-3239820
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.
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.

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.

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?

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 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?

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.
