Those are some really impressive numbers! I bought my first s9 13.5 a week or so ago and loaded up braiins+. Im strapped on how much power i can use here so I opted to run one board. The auto tuning process has it at
7.94v/ 617MHz/ 4.4Th/s @ 383 approx. watts total. Keeps my shed warm, and may pay for my sons schooling if I get lucky over at ckpool  

haven't tested yet, But thanks!

I have a dumb question I hope you can answer, What argument do I use to change difficulty for your pool? is it only by port? ive never used an s9 before and ive tried d= diff= --suggestdiff but non seem to stick.

You know I was thinking about your heater idea and it came to me, why not make it a heater & air purifier! On the intake add a activated carbon pads(they look like green scrub pads but black and usually bigger) and maybe even a paper filter, one for a lawnmower should do not hepa grade but will get the small stuff.

This idea may require some custom fabrication to hold the filters.

Not sure how the fans would handle it. But its an idea. Thought I throw it out there. I ran across this post and now have a one board going myself Hopefully soon get solar implemented once I have all the pieces.

Thanks for the Firmware, Seems to be running pretty good. I have it installed in a s9. I have a question though. With auto-tuning turned on, Is there a way to adjust the fan speed/profile without needing to re-run the entire tuning process again using the web ui?

Huge congratulations sir!

So my testing today hit a snag, Cant seem to get the Newpac past 512mhz. It down-clocks itself to 506 then runs fine. Not sure if its a lack of power from my hub, or the limits of my chip? turned it back down to 500 since I know its stable there.

Bread boarded a temp sensor and stuck it the side of the heat sink, works good. at 500mhz the heat-sink doesn't reach above 24c. Thinking about loading obs onto the Pi, and starting a 24/7 Newpac stream. Thats about the only thing I could come up with for time being to utilize the Pi a bit more.

Edit: Got a stream going ( https://www.twitch.tv/can_man ) its almost 2 am and I can't get obs to see an audio device. So no sound. Ill fix that tomorrow with some proper mining music.

Congrats to the lucky miner! and with only 50th miner is flipping awesome! The dream is alive 

If you neighbors spend enough time looking at or through your windows to be annoyed with what you do or don't have going on, Id be me more worried about the peeping toms next door. lol.

Ok, That's what I had figured but just wanted to check. Also placed the Pi back on its own supply. I did test the 10th port, it transfers data but I noticed it has a charge mode light and a data light. I have to assume I don't receive the extra amps with a data device hookup up. When i plug my phone in it switches to fast charging mode without data.

gt_addict those are some awesome numbers. Its amazing to see how little the diminishing returns are in terms of Mhz and gh/s.

It makes me curious as to how far the chip and unit could be pushed with adequate power and cooling.

Yeah that's my biggest concern and the main reason I haven't tested anything above 500 yet. I'm definitely picking up a gekko hub asap the layout, the fan header, the juice. I need one haha. What kind of GH/s do you achieve at 625mhz?

This anker's specs are meh:


Not sure if the 10th port also transfers data, but if it does its the only port on the whole that delivers above .9A. Ill test it later, from reading I believe i'm not actually supposed to be powering the Pi from the charge port, that's a bummer. (Hub must be powered by both a power adapter and an active PC/laptop USB port.) Makes it sound like it gets extra juice from the usb port as well.

Do these units operate on 5.5 or 12v?

Got everything up and running, Pushing 500mhz strong. Has anyone pushed their newpacs past 650mhz?

Just wanted to pop in and Say thanks for the amazing piece of hardware. Just picked up a Newpac to test out and it works flawlessly. Waiting on a Rpi and a hub to arrive. Once they do I hope to have the setup powered completely with solar and batteries.Then scale up newpacs as budget allows. Looking forward to the next iteration of newpac if one is in the works!!

Also I think ill be building a sensor system to monitor the temp of each miner i get running with DS18B20 one wire sensors, would attaching them to the side of the heatsink with a thermal pad give an accurate enough reading? should I use something to totally encase the sensor to the side of the heatsink(hotglue, or something) so the fans/passing air dont mess with the reading? Any suggestions would be appreciated.
