Running CGMiner

linux:
./cgminer -o stratum+tcp://stratum.kano.is:3333 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr -p x --suggest-diff 442

windows:
cgminer.exe -o stratum+tcp://stratum.kano.is:3333 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr -p x --suggest-diff 442

OS X
cgminer -o stratum+tcp://stratum.kano.is:3333 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr -p x --suggest-diff 442


CGMiner Frequency setting

Warning running it higher than the default setting will require some cooling.
The higher the frequency you use, the greater the amount of cooling required.

To run it at a higher frequency, add on to the commands above e.g.

 --gekko-compacf-freq 400

The latest version of the gekko driver (as of 2021-10-17) has a new mining option:

--gekko-mine2

This uses a slightly different mining loop that also reports all frequency changes to the screen,
and why they change if it stepped down.

There's a second option if you have enabled the mine2 option:

--gekko-tune2 60

that allows the miner to recover lost frequencies if it was unable to match the frequency
requested due to the environment, but it later improves e.g. gets cooler.
The '60' means check once per hour - default is don't do it.
The miner may just end up stepping up and down once per check if it can't do better,
so there's a lower limit of once per 30 minutes, range is 30-9999

CGMiner Git

The master git for cgminer is https://github.com/kanoi/cgminer

CGMiner README https://github.com/kanoi/cgminer/blob/master/README

That includes linux compile steps, but to repeat, on linux:
Code:
sudo apt-get update
sudo apt-get upgrade -y

sudo apt-get install -y build-essential autoconf automake libtool pkg-config libcurl4-openssl-dev libudev-dev libusb-1.0-0-dev libncurses5-dev zlib1g-dev git

cd
git clone https://github.com/kanoi/cgminer.git
cd cgminer

CFLAGS="-O2 -march=native -fcommon" ./autogen.sh --enable-gekko --enable-icarus

make

CGMiner Windows 10 32bit binary

https://kano.is/cgminer.zip
It will probably work on older windows, but I'm only testing it on Windows 10

The instructions to compile it yourself on Windows 10 are here:
https://github.com/kanoi/cgminer/blob/master/windows-build.txt

As with all USB miners on Windows, you must install Zadig and setup the miner.
This is documented in the CGMiner README https://github.com/kanoi/cgminer/blob/master/README

cgminer now has a new run option to verify it can identify shares correctly up to a hash of:
000000000000000000000000000000000000000000000000000000000000ffff

./cgminer --block-check

This is useful to check if you build cgminer yourself on your own choice of hardware.

Difficulty will of course never be that high, and no one is likely to ever find a hash that low.
That's only about 8 decimal places off the number of atoms in the universe Smiley
