OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[lano1106]

Already running 3.3.4 on bitminter flawlessly.

thank you very much for your amazing job!

[bzh]

want to move past 3.1.1 on my pi with BE's but i really dislike arch. does 3.3.4 still have usb issues with rasbian wheezy? Is there a custom libusb that works with it yet?

Sorry if this is posted elsewhere i did a few searches and could not find anything. Thanks.

As we discovered, it's not cgminer that has usb issues, it's the libusb included with the distributions, so - yes you will need a custom libusb installed if you wish to use raspbian and not move to arch (which has the new libusb). You'll have to compile it yourself. Maybe some generous soul here will create a custom libusb package for raspbian?

How to compile with the known working libusb is documented step by step in README (I added it in 3.3.2)
https://github.com/ckolivas/cgminer/blob/master/README#L112

It is actually not many commands: get, extract, configure, make, autogen.sh cgminer (with the new libusb) then the rest as usual
I have that working libusb source archive in my cgminer-binaries also:

Are you able to build the binaries you released statically against the known good version of libusb?

[Roy Badami]

The network difficulty defines how many of these you need to find before you should, on average, find a block

Where does cgminer's reported 'network difficulty' come from - and is it supposed to be the same as Bitcoin's difficulty?  (I find it's not the same - but I guess that may be just down to what the pools report?)

roy

It's there in the block header you are hashing.
Block header being hashed is: Type, Prev, Merkl, Time, Bits, Nonce.
Diff = f(Bits)

Thanks.  And of course the value reported by cgminer is correct :-)

I made the mistake of believing the figure at the top of bitcoincharts.com

Updated my binaries git to 3.3.4a + 3.3.4 master binaries/src (and removed 3.3.3a + 3.3.3 master binaries/src)

All the ones in my cgminer-binaries are statically linked to the working libusb, but dynamic with everything else.

Unofficial Mac binaries updated to 3.3.4 at http://spaceman.ca/cgminer.

Latest cgminer 3.3.3 on usb be is not working on p2pool - all rejected.
In p2pool log i see some startum errors.

Hence 3.3.4

guys quick question.

I have 2 identical 7970 cards. When my cards are cold, I see that fan speed is displayed differently for each of my cards:

GPU  0:  68.0C  50%    | 620.3M/683.2Mh/s | A:3 R:0 HW:0 WU:  7.1/m I: 9
GPU  1:  55.0C 1815RPM | 620.3M/680.6Mh/s | A:5 R:0 HW:0 WU: 11.8/m I: 9

Eventually when they get warmer, they % value gets replaced with a RPM value in the 3000-3100 range.

Maybe I am wrong bu tthis seems like a recent behavior change. As far as I know, previously fan speed was always displayed in RPM...

That code hasn't been changed in a long time. Each device reports whether it can detect RPM speed or only report the set fan percentage speed. cgminer tries to show the actual RPM speed if it can (since that's safer than a device that thinks it's set to 100% but the fan isn't spinning), and falls back to percentage only when the device reports it doesn't support RPM. If something is changing while your machine is running, your driver/hardware is doing some funkiness

Watch out, the 2013-08-14 image seems to get rid of the temp cutoff settings in the Avalon GUI, make sure you add the appropriate command-line settings, especially for batch 3.

A reminder that I've said in my announces that there is no specific batch3 support in my firmware images. Luckily the default settings are too cold for batch3 so it will not harm your device, just crank the fans up to maximum. Add your parameters to the More Options box as I said in the 3.3.2 announce. Hopefully there will be new firmware from xiangfu soon which includes all my changes as well as his batch3 interface changes.

[bitpop]

What does the Avalon interface look like?

[brocktice]

Luckily the default settings are too cold for batch3 so it will not harm your device, just crank the fans up to maximum.

Actually it quickly exceeds the default cutoff temp and shuts the chips down, oscillating as they cool down and warm back up. Only harm is lost mining time.

How can I run cgminer with windows and mine  with a avalon?`I want to connect him via USB. 

Are the avalon drivers included in the  windows version?

yes!

you have to run zadig to change to the winusb drivers. (also see asic readme)
