This is disappointing that Nicehash didn't have a response that helps us. I figure it was just a parameter or setting that we could use to help. I tried to point my miner at Nicehash and 50% rejects. I tried Antpool and I could never get the stats to show up on antpool. So I ended up on flypool and that seems to be working.
I set mine up today on Antpool and it works perfect at 15 sols 675Mhz |

I personally think the 650M Firmware, leaving it at 650Mhz is what you are looking for that will give you 13,900 Th with no temp rises, the temp rise from what i see is that the Auto Adjust Fq firmware the fans run up to 6000 which keeps them cooler, where the fans on 600M and 650M run to about 4600.. the HW faults come from a poor pool from my experience, do you use Slush?..they seem to be the cleanest
Ok ran at 650M and 662M for a week now, went up to 668M and running completely fine hashing 14,300Th temps are stable at 82.
[...]
Hay buddy, I have been running these S9's for almost a week at 14,300, 14,400 Th but i dont see much movement in the chip temps they seem static at 81, 82..maybe that is the temps,, do you have the same readings?.. In the Kernal log it says : set FAN speed according to: temp_highest=82 temp_top1[PWM_T]=82 temp_top1[TEMP_POS_LOCAL]=72 temp_change=0 fix_fan_steps=-15
FAN PWM: 54
read_temp_func Done!
CRC error counter=0
Cheers Jase

Got my 1st unit today and it is running happily OC'ed to 656, no HW errors and temps in the low 60's.
Mining BTG on MPH with 0.00% invalids after a couple of hours.
Tried NH, but as others have reported, 50%+ rejects.
Sounds great, What wallet are you using to bank BTCG?..And exchange it for BTC?.. Thanks |

Thanks a lot for this excellent work.
I live in an extremely hot area so for me reducing the heat is important and so I have tried the 840 and 820 version, somehow the 830 version is missing from the download folder.
I just want to run my antminers near the default speeds with reduced temperatures and less HW errors, please advise the best way.
On 840 with freq of 650 the temp are almost the same.
On 820 with 650 with speeds get reduced and HW errors start occurring.
Thanks.
I personally think the 650M Firmware, leaving it at 650Mhz is what you are looking for that will give you 13,900 Th with no temp rises, the temp rise from what i see is that the Auto Adjust Fq firmware the fans run up to 6000 which keeps them cooler, where the fans on 600M and 650M run to about 4600.. the HW faults come from a poor pool from my experience, do you use Slush?..they seem to be the cleanest |

Just try what your PSU accept. It has overload protection, so in case it will be overloaded, it will shut itself off.
You have really helped me understand my S9's firmware and overclocking them, just want to say thank you RadekG2 |

I can confirm that PPNLS payouts with Antpool is not working but PPS is. Also my Freq is 643 & I'm getting an average of 15.4ksol
15.4 KSol = Almost my 3 rigs full of 1080TI and Titan Xp, but less power efficient :-) Significantly, I'd estimate that overclocked z9 is running at under 500W. It is using 387 watts at 15.4 ksol Antminer Z9 mini running on 387 watts, overclocked to Freq 643? Are you sure? In that case I can connect 4 miners to EVGA 1600 P2 power supply and overclock them to 643 freq? Hay buddy, my Z9 hasn't arrived yet.. have you got it working overclocked at 643?. what pool are you using?...

Ahh okay so your just hard setting voltage then pick and choose which frequency is running best and you have it set by default to 675. So we could just go in there and set it to 700 etc.
Do you know which voltage would be the highest the bitmain 1600w psu can use. I want to run my s9 at 1550-1600w to draw around the max the psu can handle and hash as fast as possible with that psu
I loaded the 600M Firmware that is 9.3v and adjusted to 675.. i am getting better results from the 650M Firmware that is 8.8v.. I am currently running some S9's on 723Mhz at 15,300 Th. 688Mhz is about 14,200Th Give that a Go ON THE 650M firmware at awywhere between 675Mhz and 723Mhz |
|
|
|
So you set it to 9.4v for every frequency. There really is no underclocking then since when you set the voltage it sets that for each of the 21 lanes. 9.4/21=0.44761V a chip. If you are trying to underclock it for better efficiency you would need to recompile bminer and lower the voltage to whatever works best for whatever frequency your using. This is only good if you are trying to get the fastest th/s and don't care about losing efficiency since autotune was made for increased efficiency.
If I load the 600M Fixed Fq Firmware that sets a higher Voltage what will the benefit be?.. as at the moment i have the 650M Fixed Fq Firmware, and i have set the Fq between 662mhz 668mhz and i am producing a solid 14,200TH.. with very low HW faults and 0.0000% DiffA.. is more voltage for running a higher Fq?. |

Based on my experiences with Antminer D3, some boards works better at higher frequency at the same voltage level. The correct frequency was only one unique frequency. Lower didn't work and higher didn't work also. It is probably because of chained chips are dividing voltage between each chip group a bit different at each frequency.
Check kernel log for "setting working voltage" where you will see which working voltage it applies with autofreq or with fixed voltage. Autofreq boards has different voltage for each board while fixed freq sets the same voltage for all boards. I was shocked, that at 600MHz fixed firmware applied 9.3V for the chain and at 650MHz it undervolted to 8.8V.
This Is 650 Fixed Firware Fix freq=662 Chain[5] voltage_pic=108 value=880
Fix freq=662 Chain[6] voltage_pic=108 value=880
Fix freq=662 Chain[7] voltage_pic=108 value=880
set_reset_allhashboard = 0x0000ffff
set_reset_allhashboard = 0x00000000
Chain[J6] has 63 asic
Chain[J7] has 63 asic
Chain[J8] has 63 asic
Chain[J6] has no freq in PIC, set default freq=662M
Chain[J6] has no core num in PIC
Chain[J7] has no freq in PIC, set default freq=662M
Chain[J7] has no core num in PIC
Chain[J8] has no freq in PIC, set default freq=662M
Chain[J6] set working voltage=880 [108]
Chain[J7] set working voltage=880 [108]
Chain[J8] set working voltage=880 [108]
Is that It? 880 8.8V? So maybe better running the 600M Fixed Firmware and adjusting that to 662/668Mhz etc |

All miners have safety built-in cut-off temperature (can be disabled), where miner stops and cools down. Maximum speed depends on chip and VRM temperature. My own experience is that S9 survive temperatures over 110C at chips for 24/7 operation. For those who do not agree just looak at Antminer R4 which is "silent" and always works at 110-115C. Anyway, based on earlier S5, chips they unsoldered themselves under full load, so temperature exceeded 200C. They worked again when resoldered back.
So back to temperature: It is not possible to check VRM temperatures, but first batches of S9 was without heatsink on VRM. They worked well at standartd frequency, so newer batches should work well when OCed. My opinion is that only VRM temperature is the only limit of OC level, so keep temps as low as possible.
Unreliability of S9 leading to lost chips is caused by unpredicted behaviour of chips in serial chain. This will cause temporary overvoltage of some chips which will destruct them. Only one dead chip can make whole board stop hashing or prevent detecting of ASICs. Unfortunatelly, S9 still hasn't reliable overvoltage protection.
I do not agree you will shorten life of your miner in any measureable way. Chips are deeply under its maximum performance, only one unknown is VRM. Anyway I agree that even unmodified S9 is not reliable. Hope my opinion will help you.
FYI: Alexander1560 from the video claims he has working S9 at 850MHz.
Cool Thank you for your detailed answer, your experience is appreciated, I have 15 now running at 662Mhz to 668Mhz at 14,150Th 14,300Th with lessthan 10 HW faults and 00000% DiffA# they seem to be running better on the 650 fixed firmware then the Nov 17 Auto Fq Firmware.. and temps are 82 max. Cheers Jase |

The only 'safe' speed is the speed the miner had when sold. Even then an unmodified s9 is not known for being reliable.
When you overclock you are on your own and yes, you WILL shorten the miner life even more.
What do you operate your S9's at?.. I have mine adjusted up to 675M running about 14,300/14,500 TH they seem to be fine, low temps and 0% Diffa.. but its unknown territory as to will we burn boards out..or does board burning come at 15TH plus.. Your thoughts Thanks mate Jase |
|
|
|
|
Whats a safe TH go adjust to without burning boards out?..
Thanks
|
|
|
|

Ok after runnung these all day playing with the frequency.. I have settled on setting the 656.5M, that gives the S9's a solid 14 TH , its a 500 increase over standard. my personal thoughts are.. yes i can get them to 14,800 TH but at what cost?....i have been looking at burnt out boards from over clocking.. better stay safe me thinks.. until we can see what is a safe TH to over clock to.

Ok Update...
Had a couple of machines building up diffA % so adjusted UP to 706.5m seems to be running sweeter and ironed out %DiffA and zero HW errors...now 14,860 Th
|
|
|
|

Now got 10 S9,s running on 650m firmware, i have adjusted them up to 675m, i am on slushpool as i get lease HW faults from them.. want to keep these babies happy.. i had one S9 start racking up DiffA faults so i backed it off to 656.25m and its running fine..at 675m they are 14.400 Th
|

Just an update, I have two S9s running at 706m, hashing at 15.1 Th/s for a full week and no problems. HW errors at .0002%, low temps.
Hay buddy, I have just loaded the 650M FFQ Firmware to 4 of my units, they were on 13.5 auto freq, they are running perfect at 14,200/14300, the fan speeds are set at max lower i see, seems ok, but its cool outside, note: Since upgraded TH I have a......Load Average 0.92, 0.77, 0.50? Is that the power its pulling on each board? This is the load average on a standard S9 Nov 17 firmware on Auto Freq 0.26, 0.26, 0.24 Ideas ? Really impressed with your findings Cheers Thanks Jase |
