No problem I sent you the link though. Keep an eye on the temperatures as it will give some feedback as well. so run at 400mhz on the bitmain firmware at 20% fan speed and write down the temps. Flash the custom firmware and see at which voltage you get the same temps and then lower the voltage to see how low you can go before getting hardware errors.

Hi guys, I am working on finalizing the first version of the firmware now. The first release will not contain any new algorithms yet, but will add some nice features to quiet the beast
It's still uncertain if adding other algo's is possible but I will definitely give it a try after the first firmware runs stable

yes

Any word from blissz? Looks like he has not been around since the 12th.

I have some great news guys!  

I successfully modified the following:

- unlocked ASIC voltage from software. You can now increase or decrease the ASIC voltage from software
 This can save a lot of power / heat and noise. i.e. I run my D3 at 15Gh/s at below 700 watts instead of 19Gh/s @ 1200watts. On the other hand you can also decide to overclock your unit if your PSU can handle it with this unlocked vcore.
- removed fast FAN startup. (very annoying for users that run this miner at home)
- unlocked full fan control. No more minimum fan checks. It removed the low fan warnings as well.

I need to mod the webinterface as well and do some testing so it will take roughly one more week before I will release the first firmware version I guess
This first version is mainly aimed at home users to get a better power usage / hashrate balance and run it as silent as possible
 
before you ask: Adding new algorithms will be on the list for future versions

other feature requests are welcome of course

a small update on some questions I got:

- overvolting & overclocking will be possible as well. This doesn't make sense for me, but as long as you can keep it cool enough, it will be fine.
- I will add more features to the webinterface after the first version
- for now it's only tested on the October batch, but it will work for sure on other batches as well.

The status is now is that the I can adjust the voltage by hard code it in the binary, but it really needs to be a proper setting in the advanced webinterface page first before I send it out.
Fan speeds are fully unlocked already, so you can also decide to change them to a pair of silent fans on the modded firmware.
