Have you looked in the kernel log to see if there are errors there?

This would be a completely and utterly terrible idea. People that do not mine for profit can buy some crappy usb sticks and do it without having to open their computer.

More importantly, dont use an S1. Thats just throwing money away even at 1c/kwh

It shows 30 when it cant see anything. That is not a real number of functional chips just FYI

However, there is no good entry level FPGA that can run with low wattage/hashrate available to the public for a low cost.
An entry level FPGA is 100% useless. At this point in the game you need tens of millions of dollars for staff, R&D, testing, tapeout, wafer production, chassis design, controller design, software design, etc etc etc etc |

If you use the actual Avalon OS on the RPi it will give you error codes to diagnose the systems.

The trick with removing the heatsinks is to heat up and remove the smaller bottom one first, otherwise heating the top taller heatsink will loosen the solder and pull the chip right off with the heatsink. As far as removing the thermal epoxy you literally just take an x-acto knife and shave the epoxy off of/around the edge of the chip and clean it with a lil alcohol.
P.S. When heating up the heatsink for removal try and roll it back and forth slowly while heating it up, never pull straight up.

The higher the voltage the higher the Hashes you can have, that is why I want to connect to 22ov.
^^^^ This is not correct. Also, the miner isnt what cares what kind of power its fed its the power supply. All power supplies will give the miner 12v, it just depends on what input the power supply can handle. |

This forum has ALL the information you will ever need. Do some research, we are not here to do it for you.

I can help by pointing out that this is a bitcoin mining support forum and GPUs are not for mining bitcoin. Try the proper section.

No they draw under 1200w for the 6.3th version
|
|

spend the $15-20 on an old RPi and run them the way they were meant to be run. Solves your firmware problem plus a bunch more other issues you may have not run into yet.

Just buy a dummy plug, the other ways mentioned wont work.

Its completely normal. I have had machines that take up to 45 minutes to start hashing after a full cold boot power cycle.

S9 - 14th 1600w
S9++ 75th 1200w
Please explain how ANYONE looks at those numbers and goes "yea the ++ might be real"

Nobody on here has ever seen one in person and posted about it. Its vaporware at this point IMO.

is there a way to undervolt just specific miners or is this available for only for the whole batch (same controller)?
You cannot change it individually, the change affects all miners on the chain. |

What's the exact problem with the boards? Can it be repaired or must it be replaced?
There are many possible problems and none of them are fixable by the end user. Your only option since for some reason you didnt buy direct from the manufacturer is to send the bad board to bitmainwarranty in Colorado and pay them to repair it for you. |

You guys are giving out bad information.
The s9 has always had 63 chips per board for a total of 189.
The t9 has a reduced chip count at 57 chips per board for a total of 171.

can i use 2 bitmain apw3 PSUs to power 3 avalon miners?
I have tested the Avalon 741 boards pulling 550-600watts each. With the setup you describe you would be trying to pull 1800w out of a 1600w psu. I wouldnt recommend it. |
