Ck or Dogie or anyone, Can someone explain how to use the Sept 26th Firmware with Cgminer 4.9 with extra nonce?
Installing thru ssh to make sure it stays put thru a reboot???
I wanna be able to use the first firmware with the latest miner so i can use voltage control to downclock my miner.
If this is for the S4 then go here https://bitmaintech.com/support.htm?pid=00720140930114518599JXGHWWD80660 and download this : initramfs.bin.SD-20141016.tar.gz It was the last firmware that allowed underclocking (Oct. 16th 2014). Go to your gui and navigate to the Miner Configuration tab then the Advanced tab. At the bottom you can search for where you downloaded the firmware and upload it to the S4. Miner may reset and when it comes back you may need to reconfigure your pools. Here gives you some predetermined underclocks https://bitcointalk.org/index.php?topic=796839.0 it's the beginning of this thread pg. 1. No need to ssh into it as long as you have a windows computer. Underclocks on that page don't work! What firmware are you using? |

The best underclock ive been able to achieve was freq 100 volt 0670 Now that i have gone thru all the underclocks & voltages using a kill o watt The above said freq & volt dont do anything to change the power output The 640 watts returned thru the kill o watt is merely the power drop from 740 watts to 640 watts caused by the fans running slower as the machine is running cooler... Not a true underclock in my book Please tell me about your underclock settings & what wattage was achieved?? I've been busting these forums butts & bitmains for ages to get something done. Please tell me u used a kill o watt to prove ur settings! My current firmware is : Thu Oct 16 15:58:23 CST 2014 |

Please do research before chiming in blindly! If the S4 does not support Undervolting, I do not have one, then it's a great pity as unlike the other Bitmain products it has the chips that should support it. Namely the TPS53631 3-Phase VR12.5/VR12 SVID compliant PWM controller. This is designed to support processors with a core voltage range from 0.5-V to 2.5-V and is fully programmable. Examination of the circuit should reveal if programming is supported although this is complicated by the fact that the data sheet is not generally available. This is what you get to on the TI website. This device is designed specifically to power Intel processors under a strict disclosure agreement with Intel Corporation.
The end user must have a current CNDA in place with Intel Corporation to access this information. Rich |

Hey there HerbPean! If you see "APLUSPOWER" on a sticker on a side of the PSU, it's the second version. But the second version is not a lot better than the first one, they are dying one by one, slowly...  |

Thanks for the info guys, Any good cheap replacement ? Prelude, did you get my PM ? (About the fan replacement) While fixing one of my s4's PSU, I connected it with 2 s1 PSU's and it worked well. I'd guess on the total of 1400W per s4, 600W per board and the rest for the controller should be ok. Just try to distribute the power equally, and make sure there's more power on the hashing boards than the controller. Of course you won't be able to close the cover... |

Can someone explain what the J7 controller is on the S4??
Is the miner basically made up of 4 miners or boards chained together??
My understanding is the J7 has some sort of current issue causing it to run at 0765 volt instead of 0725.
Now as this is an issue & some of us are trying to underclock our machines to get a better voltage off it, Is it possible to disconnect the J7 so that the machine will run at the lower clock / voltage??
Just a thought???

If you read all the pages then you would have had your answer and noticed everyone still believes it's possible even though Bitmain has taken that ability away it seems. If you want a true answer hit up dogie. Quit talking smack about people trying to help.
