Thats the settings i used with my old 5 bitburner too since i optimized it to the mV. And i got similar results. And someone i sold bitburners too get the same good results too. I dont see whats the problem.

I mean its the same place they are placed, settings are same, cgminer is newer, psu is burnins partly, its rpi, though another rpi, all are flashed to newest firmware... i dont see the difference.

Currently running on BTC Guild. I was using Eligius but for some reason I can't connect to it with cgminer anymore.

Nothing donne, just CAN pluged in
I think it`s a matter of those little jumpers...
where need i put them ?
plisss help

CAN bus terminated at both ends with jumpers?

just got my stuff - 6 boards
puted it together
and connected with 1 usb cabel and a CAN cable
What need i do to run them all, just one unit works

Really good result so far... whats your settings? And what pool do you use?


I tried that with my old bitburners once and the result was far from perfect. Ill give it a try again.

Hashrate looks good to me. As a rule of thumb: "(MHz * Chips) / 1000".
In your case (btb1): (450 * 20) / 1000 = 9 Gh/s; so your 8.966Gh/s is pretty close to that.

Why don´t you use the --avalon-auto ?
So you don´t have to look the whole day at your bitburners. cgminer runs every cluster at the optimum.

OK with my settings I'm getting this:

That seems like a reasonable error rate and hash rate correct? The BTB 0 is the 10 chip and the BTB 1 a 20 chip.

Maybe it's time someone does some experimenting with the number of boards in a stack versus total hashrate.
So 1 stack of 8 boards, 2 stacks of 4 boards, 4 stacks of 2 boards and 8 single boards.

It would require 1 canbus cable with 8 connectors + 1 usb cable, 2 canbus cables with 4 connectors + 2 usb cables, 4 canbus cables with 2 connectors + 4 usb cables and for the last test 8 usb cables.

cgminer can be pointed at the right stack with some command line arguments that I will have to look up.

all cgminers report the shares found to a separate logfile, so that can be used as a good source for the comparison.

Anyone with too much time on his/her hands?

Im a bit puzzled now. I host some miners for another user. 3 bbxx + 1 bbx in one stack. It runs at 26.5GH/s, thats 7.57GH/s for one bbxx. Not much. I previously had 5 miners and they ran at 43.75GH/s, which is 8.75GH/s per bbxx.

Now i got 10 more miners that run in another stack. Its 10 bbxx. And they only run at 64GH/s. Thats 6.4GH/s per bbxx only.

I dont know whats wrong. All run in one cgminer-instance, so two miners are recognized. All miner are blinking with all colors.

I ran my old 5 bbxx, that i dont have anymore, at the following settings:

--avalon-options 115200:10:10:28:450 --bitburner-voltage 1334 --avalon-temp 30 --queue 6

I ran the 3.5 bb at

--avalon-options 115200:8:10:28:450 --bitburner-voltage 1334 --avalon-temp 30 --queue 6

and the 13.5 now at

--avalon-options 115200:28:10:28:450 --bitburner-voltage 1334 --avalon-temp 30 --queue 6

I found that the second value in options should not be too low, but it doesnt matter if its too high. Since i dont know exactly how to setup for 2 stacking towers i simply used 28.

But i dont really get whats the problem. Why should my old miners run faster and the newer ones slower? queue 10 didnt change anything too. HW is under 1%.

7.5 miners are powered with a psu from burnin, the other 6 with an Seasonic Platinum SS-1000XP. The workload of the raspi is at 7%. Could it be differences in pools used? I used bitparking.com with my own miners and now bitminter.com is used. All boards are on firmware 1.0.2.

Do i really have to start testing and tweaking everything from the start because every setup needs its own settings? I mean it cant be normal that 10 miners only bring 73% of the hashrate of 5 miners got before.

cgminer didnt change in an unfortunate way right? 1334mV and 450MHz i used before can be used now too. In older cgminer-versions i had to manually edit cgminer sourcecode.

Someone knows?

You should replace the 35 with d since you have to change that value everytime you change the MHz otherwise. And when changing the MHz you need to change the voltage too otherwise HW-errors are too high.

No, it must be --avalon-options 115200:2:10:35:380 --avalon-auto  --queue 4 --bitburner-voltage 1285

Cgminer sees every board apart when it has an usb cable. The "total boards x2" number only applies when they are in a cluster (i.e. with canbus cable). Without it, it's just "2". (I think that is because a board originally had 10 chips on it.)

Look at burnins site: https://www.burninmining.com/news/
You can find this:   The next value is the number of miners, this must be the number of boards in cluster multiplied by 2
So if you have 2 bitburners, you have to choose the number 4:

--avalon-options 115200:4:10:35:380 --avalon-auto  --queue 4 --bitburner-voltage 1285

Maybe the settings are too fast and too cold.
I´m running my Bitburners with this:

--avalon-options 115200:32:10:35:380 --avalon-auto  --queue 4 --bitburner-voltage 1285

With this settings the bitburners are running with 435 to 446 MHz, depending to the temperature. ( At the moment 445 MHz, 45°C)

They are running fine with a raspberry pi.  I used this tutorial:  https://bitcointalksearch.org/topic/super-tutorial-raspberry-piraspbiancgminertightvncwifi-at-boot-233392

Does anyone know what it means when cgminer says this at start:

I don't have the CAN-BUS cable so just have a BitBurner X and a BitBurner XX each on separate USB cables. I'm using these cgminer settings:


Does that look right for my setup? I seem to be getting pretty good rates.

My bitburner from zefir batch 3 shipped today. Thanks burnin! It will be an adventure to get it running with my little Minepeon rPi I bet.

Regarding the firmware you should have BB_Firmware_1.0.2.hex from burnin's website. And last version of cgminer.

Regarding the settings. Too much voltage imo. For 380 i use  1170mV, 390 - 1200mV and 400 - 1230mV. I didn't go higher because i have the boards in a warm room.

install the WinUSB driver with the Zadig USB tool.

http://zadig.akeo.ie

you have to click 'show all devices' and then choose the bitburner and install the WinUSB driver. then your cards should be recognized in cgminer.

how?
My Ubuntu Laptop seems fine with the boards and hashing, but with windows it shows:
