OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.10.0

[matt4054]

I have a breif functionality question.

I recently purchased an awesome 7990 for scrypt mining (and gaming) but I am running into issues using my win7 OS when mining at full capacity (as expected). Previously I owned a GTX 560 Ti GPU which ran everything perfectly. My main question is: is it possible to reconnect my GTX 560 (I've currently unplugged it) to run my desktop and other menial tasks while keeping my 7990 dormantly mining through CGminer?

This way I can still use my 560 to watch online video's, while my 7990 is hashing away. Possible? I've had a good look around but can not find the code needed for this.

I see nothing preventing you from doing this. I guess you will find documentation saying that mixing AMD and nVidia drivers is not a good idea. I did it on one of my rig, and the only issue that I had was with the initial GPU detection, i.e. I had to go with the nVidia card alone first, install drivers, then add the AMD card, (re)install Radeon drivers, and then it worked.

Of course, use the -d <x> switch with cgminer where <x> is your AMD device ID (cgminer will use all GPUs by default)

Hi,
My question is regarding the AMD SDK and Catalyst versions to be used with cgminer 3.7.2 for scrypt mining with HD6870 on win7 64bit.

I know that the right SDK and Catalyst versions are very important for the maximum hashrate. But the thing is that, since cgminer 3.7.2, newer versions of SDK and Catalyst have been released but cgminer's GPU support miscontinued with it's newer versions. So I'm not sure if the newest SDK and Catalyst versions are the best to use with the old(3.7.2) cgminer, or should I stick with the best known old versions?

From cgminer SCRYPT README
"The choice of driver version for your GPU is critical, as some are known to break scrypt mining entirely while others give poor hashrates."

From cgminer GPU-README
(regarding AMD SDK)"The best version for Radeon 5xxx and 6xxx is v2.5, while 7xxx cards need v2.6 or later, 2.7 seems the best."(there's v2.9 now)
Thank you.

[chek2fire]

No. At the moment use the source and patch it , file driver-bitfury.c line 417

and what i have to edit in that line?

Code:

info->osc6_bits = 54;

you can change the frequency, default is 54

ok thanks! it works

Yes, btcguild is a separate bug, sorry. BTCguild is the only pool that uses the redirect feature in stratum which was added blindly a long time ago when stratum support was first added and no pool used it. Cgminer's implementation is unfortunately buggy and the only workaround till I can fix it is to connect directly to btcguild's redirected url directly or use a different pool to avoid the crash.

I hope you figure this out quickly .

 I thought this was a hardware issue when I first saw this since my drillbit devices were that last thing to show errors before windows tried to close it.

I need's my btcGuild.

Hi, I'm having trouble getting one of the API commands to work..
All other commands I've tried and used work perfectly but I cannot get the 'zero' command to work?

zero|Which,true/false (*)  none          
There is no reply section just the STATUS section
stating that the zero, and optional summary, was done

If Which='all', all normal cgminer and API statistics will be zeroed other than the numbers displayed by the usbstats and stats commands
If Which='bestshare', only the 'Best Share' values
are zeroed for each pool and the global 'Best Share'
The true/false option determines if a full summary is shown on the cgminer display like is normally displayed on exit.

How do I specify what to zero using the 'which' parameter?
I've tried:
cgminer('zero|which=all',false);
cgminer('zero|which="all"',false);
cgminer('zero|all',false);
cgminer('zero',which=all,false);
cgminer('zero',all,false);

and probably all other variants of that.. From what I can make out, all other commands only have one parameter and work fine, like restart or switchpool etc..

Any help would be greatly appreciated!

EDIT: I should mention I'm using MinePeon on the Raspberry Pi and the 'cgminer' function above is this:

Code:

function cgminer($command, $parameter) {

        $command = array (
                "command"  => $command,
                "parameter" => $parameter
        );

        $jsonCmd = json_encode($command);

        $host = "127.0.0.1";
        $port = 4028;

        $client = @stream_socket_client("tcp://$host:$port", $errno, $errorMessage);

        if ($client === false) {
                return false;
        }
        fwrite($client, $jsonCmd);
        $response = stream_get_contents($client);
        fclose($client);
        $response = preg_replace("/[^[:alnum:][:punct:]]/","",$response);
        $response = json_decode($response, true);
        return $response;

[techman05]

What is a triple equal sign mean? I would have thought if(client==false) then return a 0 or a 1 and then another statement to check the return with a message if you get a failed to start error since in the code you gave you don't have a message specified.

[DavidB445]

=== is the same as == but also compares the type as well value, and must be the same to return 1 otherwise it'll return 0 regardless if the value is the same.


"cgminer(zero)" returns "[Msg] => Missingzeroparameters" Obviously
"cgminer(zero,all)" returns "[Msg] => Missingparameter:true/false"

But adding the true/false parameter still returns the same Msg..
"cgminer(zero,all,false)" returns "[Msg] => Missingparameter:true/false"

I've gone through pretty much every other API command and they all seem to work but for the life of me this one just won't work

Tripe equal in PHP: operands must be equal and of the same type (rtfm)

Hi, I'm having trouble getting one of the API commands to work..
...

No idea what that PHP you are using is, but as the API-README says, the zero command is:

zero|Which,true/false

i.e.
zero|all,true

or JSON
{"command":"zero","parameter":"all,true"}

Edit: I will add that it looks exactly the same as:
addpool, poolpriority, poolquota, setconfig, pgaset, ascset
So I guess none of those worked for you either

[DavidB445]

The php function I'm using is from the MinePeon OS for the Raspberry Pi and I just used it as it worked and I managed to get all other functions to work just this 'zero' that caused the problem.
https://github.com/MineForeman/minepeon-base/blob/master/http/inc/miner.inc.php

AddPool works fine using:
cgminer("addpool",$poolAddress . "," . $poolUser . "," . $poolPass);


EDIT: GOT IT!
cgminer('zero','all,true');
Returns "[Msg] => ZeroedAllstatswithsummary" and has indeed reset the stats to '0'

I was misreading the "|" as if it was asking for "zero,all","true" but instead its the other way around "zero","all,true"

Been looking into it. I was unable to reproduce this at all locally so perhaps it's better or perhaps I just don't have the right combo of hashrate and circumstances. I've done some generic changes to make it more robust. There may well be a second issue with btcg related to the frequent restarts it's had lately but I have no firm leads on that.

libcurl-4.dll is missing from my computer, this is the error message I keep getting, when tryin to open the cgminer.exe

Thanks for checking. Maybe it helps checking the issue with a p2pool:

stratum+tcp://elizium.name:9332
start - looking for devices - coredump

I noticed --nfy-bits - thanks :-)

[rgr_rgr]

It seems there is also a problem with stratum+tcp://stratum.triplemining.com:3334 now. It is always marked as dead. The old version is running on another machine - there the pool is alive. Restart doesn't change anything on one of the machines.

I'm set for level 16 in load balance mode with about 25Ghashes pointed at it. If you have it right, it shows up after less than 30 minutes. I was trying to watch a flash video when I last noticed my computer getting chunky which eventually led to me trying to fast disable btcguild ,but it was too late and then to get stability back I ended up voluntarily rebooting my system (pc was looking to update my display , network drivers and .net service packs, so I needed to anyway) Picture below is not from most recent event but how I found it after leaving home for a few days not knowing this would happen.

I hope that gives you something to look into and hope it has nothing to do with pm to check winsock headers having problems with compiling.

[Big Time Coin]

Can someone please build a windows version with hashfast-enable?  I have been unable to build it following the windows build instructions, it keeps crashing when I try to ./configure.

[techman05]

Is it giving an error when it crashes? Other than trying changing it to --enable-hashfast instead of hashfast-enable make sure your packages are right and that the version your compiling has hashfast built in. I haven't successfully gotten cgminer to compile but you can read my edited howto on my github version that I tried to use to solve a problem with winsock errors popping up on being made with "make"  here https://github.com/techman05/cgminer .

Hope that helps

[Big Time Coin]

--enable-hashfast dies when checking c compiler
-enable-hashfast dies when checking for cross compiling
default CFLAGS="-O2 -msse2" ./configure dies when it thinks libpthread is not installed.  But I have all libpthread packages installed in MinGW, so this baffles me.

That's why I am asking for someone who already can successfully build a windows build to do so with --enable-hashfast, because I have spent much time and effort in attempting to do so and have not been successful

[techman05]

Yeah that was my problem libpthread "isn't" installed, you need to uninstall that version and install it via shell. That was one error I googled and edited in the windows compile file. After that I'm still in the dark waiting for ckolivias to check his pm's and see what the hecks going on with the make. We don't need two people getting eaten out by minGW user email lists.

**************************************************************************************
*Make sure you have the right pThreads version *

You might need to install a diferent version of it to compile I needed
 mingw-get install mingw32-pthreads-w32-dev

This reason alone made me give up windoze. Not to mention the frequent restarts because of updates .Set up a raspberry pi changed some of the instructions to compile newest version and been happily hashing since December with no down time. If you don"t like soldering then save some money and skip the lcd.
