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

Underclocks on that page don't work!
What firmware are you using?
I have used all firmwares...
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
