not much, just more hw but not much more hashrate ....

i tested 870mV with 750MHZ, Hashrate is 16.2T and hardware error is 1200 per day. i want to know, if i increase frequency with low voltage value, my device is damaged ? or just hasboard can't increase ideal hashrate ?

I have a 13.5T S9 and I turn 900mv for 750mhz ... in my opinion 800mhz with 870 seems too low, depending on the efficiency of the card, 800mhz it should rather between 900 and 920mv

hi, thank you.
what happening on my hardware when increase frequency without increase voltage ?

Hello Guys
i have 2* s9j with 1600 PSU and running custom firmware. this device cooling with mineral oil in average temp is 50 C. i want to overclock with changing voltage and frequency.
can i change frequency to 800MHZ and set voltage to 870mV ? or increase voltage and frequency together ?
i change frequency to 800MHZ and Voltage to 870mV and power consumption increase to 1540W . my change is standard ? Huh

If we were, we could work on some liquid-cooled S9s together Cheesy

Thank you for the tutorial, it got me started with editing the firmware once you showed how to compile it. You can see how useful it was by the fact that I downloaded it as reference.

Cool, glad it helped.

That's you in the tutorial Tim?, because you must be my twin brother then, you look and speek a lot like me.

Edit:
I actually saw you credited me at the begining of the post.

, nevermind, you're not my twin brother.

hi guys

noted that the Alexander1560's smart tutorial has disappeared from YouTube...
(https://www.youtube.com/watch?v=eD5F_KHkkqQ);

another hit of the Bitmain Chinese censorship?

if anybody saved the video clip, please PM it to me!
thanks

I think the readings from other firmware is PCB temp while the other firmware is for chip temps which should be different.

You can check the logs by searching local temp and middle temp result.

For other references, you can check this post. https://enforum.bitmain.com/bbs/topics/3696

Thanks for the hint!
I guess I will have to set back one of the S9 to autotune to compare temps.

Yeah, thats why I am asking. In the meanwhile I also have units, that show normal temps when using fixed freq. fw. So its a bit strange. Thats why I thought of maybe wrong readings.
What do I check in the kernel log?

emmm when i did mine were running at 4600 when my auto machines were at 6000 hence why i said they run hotter. so i wonder why they go to crazy temps when clocked?...

Just checked. In fact, the autotune miners run the fans at slower speeds.

The fans run slower RPM's check it out.

If the readings are right, can someone explain this:
On autotune FW @14TH I get 90°C. Same miner with 650FW and stock settings @14TH shows 110°C. Power consumption is the same. So why get the chips hotter?

82°C-95°C I think just fine for Antminer devices.. Don't be afraid like that,this devices can handling with max. 125 °C.so I wrote to Bitmain and they said me this.

80c above is fine, but not so good and if you can decrease the temps below 80°C your miner can live longer than the higher temps.

I think the miner s9 will automatically shut down when overheating or the temps reach 115°C if you force the miner to the higher setup your hashboards will die fast. So, keep the temps lower than 80°C if you want the miner to live long.
