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

[-ck]

What I need is to have a complete nonce run on a given work and know that it succeeded or failed.  Or, less useful, at least know which nonce values were tried and failed.  Is there different hardware and/or software that will do this?  Or another option?

Only with CPU mining can you get a guarantee you'll check all nonces. On the other hand, the Icarus devices you know will mine from nonce 0 up to where they found the share so if you have a work item with a known nonce you can always use that. They don't return anything if they don't find a share though.

ckolivas,

Any idea what might be causing my Yoli boards to behave poorly?  Also, if you need me to post more logs or different logs I'm glad to do that.  Hope all is well.

No idea whatsoever, but they simply do not seem to be hashing at all based on your logs. Voltage, frequency, power, heat who knows....

Thank you for your help and sorry to be asking more questions.

Can the difficulty level of the share be modified?  If it were set to the same difficulty level as the work, wouldn't you either get no share or find a block?

It's entirely hardware dependent. I suggest you only work with hardware that you know the protocol of yourself...

can i use CGMiner for mining altcoins? im just newbie in mining 

[pekatete]

This has probably been asked before, but I can not seem to find it.
I have added a script (to an S3's scheduled tasks) that runs every 6 hours to restart cgminer depending on some condition, however I get the following response when the conditions are met and it tries to restart cgminer:

Code:

Reply was 'STATUS=E,When=1418173650,Code=45,Msg=Access denied to 'restart' command,Description=cgminer 4.6.1|'
[STATUS] =>
(
   [STATUS] => E
   [When] => 1418173650
   [Code] => 45
   [Msg] => Access denied to 'restart' command
   [Description] => cgminer 4.6.1
)

The critical line that call for the restart is

Code:

cgminer-api restart

Do I need to add any options to how I call the script or to the command to restart?

EDIT: OK got this figured out, I changed the PARAMS line in the file /etc/init.d/cgminer to included  --api-allow $_aa and restarted cgminer, and now I get:

Code:

Reply was 'RESTART'
[RESTART] =>
(
   [0] => RESTART
)

Though it seems the UI shows cgminer has stopped, it does not restart, I have to manually restart it. Is there a delay before cgminer restarts and / or can this be set / changed?

Hey guys, I am new to Bitcoin mining and I just got the BitMain Antminer U3, I followed the guild on how to get it up and everything but for some reason when I get to the part of actually running the CGMiner, it says that there are no devices connected. I connected my device using Zadig and everything but CGMiner doesn't see it. It doesn't even see my processor that's in my computer. I have to right version of CGMiner and everything.
If anyone knows what is wrong, please help.
Thanks in advance!

ckolivas,

Try only enabling one die at a time by setting the voltage to the other dies to 0. You might find you have one bad die that is preventing the whole chip from running.

Trying to run some Terraminer IV direct from linux usb.

I keep getting the "Notify bad match work" error.  I am running cgminer 4.8.0.

I am getting good hasrate, can I get a little better by eliminating the bad match work?  If so, how do you suggest.

Searching google about this problem, I read another comment elsewhere someone said ckolivas said to use the 4.3.4 version for Terraminers. ??  That was 5 or 6 months ago.

Just ignore the warnings if the hashrate is ok. You can only decrease the errors by running them at lower speeds. Current version is fine for them, I'm just surprised you have one that still actually works since their failure rate is so high.

[altcointalk14]

Thank You.  Yes lots of failures.

I have a couple of the Terraminer boards that say No Temp sensor - shutting down.  The board appears to be OK besides that.  Is there any way to disable the e temp sensor requirement?  I know that I am keeping these chips in good temp range. The worst that can happen is making a bad board bad.    Thanks again.

What is this exactly?! Does it works?

Hello guys.

Could you do compile this version of CGMINER 4.8 for antminer S3, please?.

Thank you in advance.
Best regards.

Dear ckolivas,
Can you give us instructions of how to install cgminer 4.8 on KnC Saturn?
Thank you very much 

Best regards

I have asked here before but never got an answer, so I'll try again.
When I call the api from my S3 via a scheduled tasks (cron job) and a script to restart via the API call:

Code:

cgminer-api restart

cgminer stops hashing but does not restart.

The line that calls the script in scheduled tasks is:

Code:

0,30  *  *  *  *    root cd /sbin && ./hashRestart >/dev/null 2>&1

Via putty, I have run the cgminer-api vrsion command and get this (in case it is relevant).

Code:

My question is: Why is cgminer not restarting and am I missing any arguments to the API call?[/code]

New release: Version 4.9.0, 16th December 2014

Mainly the Avalon4 driver.


Human readable changelog:

- Avalon 4 driver. This device has a unique usb communication chip and has Manufacturer and product id filled in so it *will* be detected reliably. As per default for cgminer it needs no command line options to work, just remember to copy your udev rules file to enable regular users access to it (or run cgminer sudo). See ASIC-README
It comes with the following options (most of which are self explanatory or you shouldn't really touch them):
--avalon4-automatic-voltage Automatic adjust voltage base on module DH                                                                                                                                                                                                                               
--avalon4-voltage   Set Avalon4 core voltage, in millivolts, step: 125                                                                                                                                                                                                                               
--avalon4-freq      Set frequency for Avalon4, 1 to 3 values, example: 45:385:370                                                                                                                                                                                                                   
--avalon4-fan       Set Avalon4 target fan speed range

--avalon4-polling-delay <arg> Set Avalon4 polling delay value (ms) (default: 20)                                                                                                                                                                                                                     
--avalon4-ntime-offset <arg> Set Avalon4 MM ntime rolling max offset (default: 4)

--avalon4-aucxdelay <arg> Set Avalon4 AUC IIC xfer read delay, 4800 ~= 1ms (default: 9600)                                                                                                                                                                                                           
- Added a small change to look for null data being passed to the usb transfer in the hope of avoiding the crash with Yoli boards some are seeing.
- Added some basic duplicate share checking to try and capture them per driver and flag them as hardware errors, and filter them out.

The basic output of the faulty cgminer is "clDevicesNum returned error, no GPUs usable  All devices disabled, cannot mine!" - I have googled and read everything around this error but nothing helpful.

GPU mining was removed and support was dropped a long time ago from cgminer, please use software that is supporting it instead as you won't find help on this thread for it. I will move your post to the relevant altcoin mining section.
