WARNING THIS WILL (probably) VOID THE WARRANTY ON YOUR MINER

18/11 recommended UPDATE

Instructions:
Recommended, set the miner frequency at 400mhz and set your fan speed manual at 25% before flashing.
Flash by going to "System" -> "Upgrade" -> "Flash new firmware image"
After flashing, check the advanced settings page and start at the lowest voltage setting and 400mhz. From there increase your frequency to see how high you can go at the lowest voltage setting.

Changes 18/11:
- fixes the pool priority, it will now mine on your own backup pools when your first pool goes down.
- Dev fee lowered to 1,5% (it was actually 1,66%)

Changes 17/11:
- fixes the high fan speed when switching to the dev pool and back to your main pool
- fixes the close PIC and need reboot!!! error on the original bitmain firmware
- Made the ASIC default voltage less confusing as it is now comparable to the default bitmain voltage.
- Lowered the AUTO profile fan RPM's a little bit.

know issues:
when using the AUTO fan profile, the fan starts at a too high RPM after powering up.

It's really experimental so here are the terms:
- I am not responsible for any damage to your miner, flash at your own risk
- You're not going to complain about the 1.5% mining fee.

what you will get:
- saves upto 20% energy consumption on lowest voltage setting so it runs your miner cooler / save energy costs.
- in the lowest voltage setting you can run this miner really silent now.
- no more high speed fan's during startup on fixed fan mode
- no more low fan warnings (the fan speed is fully unlocked).
- no more temperature reading errors / reboots
- a first version of the unlocked voltage. It's possible to both undervolt and overvolt. I advice to set it to the lowest possible setting and increase the frequency until you get HW errors. Then you found the sweetspot of your miner.
- possibility to flash back to the default bitmain firmware.

Some startup settings to get you going:

for silence and best efficiency / miner lifetime (my personal preference)

Expected hashrate: 15Mh/s to 17 Mh/s
Expected power usage: 700 - 780 watt

set the frequency at "400mhz", set the voltage to "lowest". Now slowly increase the frequency until you see HW errors. When you have a few HW errors an hour you found the sweet spot
set the fan speed manual somewhere between 20 - 30 percent. Chip temp should be somewhere between 75 - 80 degrees max.

For stock performance at lowest possible power usage

Expected hashrate: 18-5Mh/s to 19Mh/s
Expected power usage: 950 - 1100 watt

set the fan speed manual to 50% (adjust this later to your needs. Max chip temp should be 85 deg)
set the frequency at "525mhz", set the voltage to "15". Now decrease the voltage until you see HW errors. When you have a few HW errors an hour you found the sweet spot

For Extreme performance (this is not recommended for 24/7 usage)

Expected hashrate: 21Mh/s
Expected power usage: 1300 - 1400 watt

set the fan speed manual to 100% (adjust this later to your needs. Max chip temp should be 85 deg)
set the frequency at "600mhz", set the voltage to "20". Now decrease the voltage until you see HW errors. When you have a few HW errors an hour you found the sweet spot

Special thanks goes to:
- All the first beta testers
- cryptonitro for this awesome new Antminer icon

Support on this mod project is more than welcome as I want to have a spare D3 for modding the software. A (damaged) donor D3 or S9 would be very welcome as well, as this baby really needs some mods too

so why is there a devfee? aside from the fact your like every other greedy fucker trying to get there slice of the pie. doubt you remade the whole firmware, Id bet you took there firmware and just added some fix's. nice to see people stealing other people work. and trying to make a quick buck, hope bitmain sues your ass
