Screw Bitmain...this is how you get a 2 in 1 miner by yourself Cheesy

Might have some fun stuff for you guys soon (I figured out the voltage controller which is how I hit 800mhz stable btw).

Are you using a voltage app to adjust please educate!

Unfortunately no, trying to build a solution similar to my L3+ voltage app, but currently I had to hack into the voltage controller and control it externally via a Raspberry pi. This is what it looks like, and doubt most people will want to do this to their brand new units:

Seems like bitmain saw what I was doing with their L3's and they shut off the user space i2c interface which controls all this stuff, they also haven't release the firmware so I can't hack that to enable it. Either way even if I can get it working with the internal controller, you will still have to pull your boards and shunt two resistor pads to connect the voltage controller i2c lines, they also purposely set these lines disconnected so there is no possibility for normal users to change anything.

All this makes sense when you look at the hardware, they are running these way below half power of what they can output...so they REALLY don't want people to know this. These things are polaris sized dies ~200mm^2. Each of these dies can easily do 100 watts each with proper cooling (vs the stock 20 watts). This is definitely the most advanced ASIC bitmain has made, and you can see all the billions they are making is going into serious R&D.

Even their voltage controllers are in the "GPU" territory now. This is run by an advanced muti-phase regulator. This particular board has 6 phases, with only 4 phases used. Each phase has a 60amp capability, so total output of 240 amps. Stock voltage is set at 800mv so were talking 200 watts PER BOARD, with only 80 watts utilized. Im already order parts for the rest of the phases since I'm already running near the max with 20 KSols/s I'm running now. That will bump things up to over 300 watts and over 25KSols/s. These chips will definitely be running at 2KSols each in their big miner.

Some great info here, what do you feel would be the recommended max chip temp for the included cooling solution?

These are GPU sized dies...I would not push them more than what you would push your normal GPU. These are not the normal small packaged dies Bitmain uses, so they can definitely not take 90C+ of continuous temps before something goes wrong.

I don't push my GPU's past 72-75c max so sounds like some of those out there with extreme overclocks should take note of the temps.
