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

I think you have a great program given that its far exceeding everything else, but some beginner instructions would be great!
I tried cgeasy with one pool, and it didnt work, but switched to d2 pool and its working now. I have a radeon r9 280x and I am getting only avg 12.24 KH/s, with these settings:
color 57
cgminer --scrypt -o stratum+tcp://pool2.d2.cc:3335 -u N[e]wBie.1 -p mypassword --shaders 2048 --intensity 13 --worksize 256 -g 2  --gpu-powertune 20

Using 13.1 drivers from catalyst.  Is there anything wrong with this ? I will investigate, I appreciate the help. Thanks!

Unfortunately scrypt and GPU support altogether has been removed from CGMiner starting 3.8.x, as CK only wants to focus on Bitcoin now.

If you want to run it with an older version (up to 3.7.x I think), try without --shaders and -g first, and start with an intensity of 11 or 12 (to avoid HW errors), then start increasing and adding tweaks. I have bought a new R9 280X yesterday and I'm only getting about 610 khash/s instead of 750 right now, it still need tweaking. For some cards (especially the high end ones like 79xx) it took me hours to get anywhere near the maximum scrypt hash rate, while SHA256d was super easy.

Check out the litecoin hardware comparison page.  Has great tips for the 280xs.  I got mine running up to par super fast with the tips there.

what won't start? cgminer.exe starts up and when I enter in the "instructions" on the pools, I get failed to resolve, even when trying to solo mine I get errors. What dlls have to be copied into the system folder, and what for? are there any instructions available for this program? Thanks for the reply, I am hopelessly lost right now after hours of trying to get this to work, so anything that lets me explore a way to get this to work is great.

First off, sorry if this is one of those questions that has been answered - I'm SURE it has.  693 pages of posts is impossible to search through.  The search tool gets me so many hits it might as well get me nothing.

I have 4 rigs running 7950 GPUs like a charm on cgminer 3.1.  I just purchased a R9 270x and have learned that it will not work without the latest AMD drivers.  So, that's where we're starting.

I'm building out a completely new rig.

I just built a BAMT image on an USB:  BAMT 0.5c.
I've upgraded to the AMD latest drivers:  amd-catalyst-13.11-beta-v9.4-linux-x86.x86_64.run
I just pulled the latest GIT tree for cgminer:  3.8.5

And I ran my usual script and nothing works.  Apparently all kinds of things have changed.  All the SCRYPT readme files are gone.  The ADL includes directory is gone.  The README does not reference anything SCRYPT any more.

If someone could start me off on the right path, I would very much appreciate it.

cgminer no longer supports GPU mining.  I believe 3.7.2 is the last version that supports it.

M

Well, dammit.

I guess I have my answer.

[bdiddle]

So I need help on xubuntu. The main site is down, but when I try downloading cgminer from github, the files  get are only 25.2K

Is it a problem on my end or github?

thanks.  It does. I'm on the 3.7.2 path now... and will read up on the new branch.  I suppose it had to happen... Litecoin has to surpass bitcoin sometime.

Since you're running BAMT, you may want to check out the latest Scrypt version of BAMT 1.2 that bee is working on (posts in reddit and Litecoin forums).  He's updated the AMD Drivers for the new R9 cards.

Has anyone successfully configured cgminer on Mac to see their Bi•Fury? If so, what did you do to get it recognized?

Thanks in advance.

Thanks, I'll give it a whirl.

Straight from README:

OSX:

On OSX, like Linux, no drivers need to be installed. However some devices
like the bitfury USB sticks automatically load a driver thinking they're a
modem and the driver needs to be unloaded for cgminer to work:

sudo kextunload -b com.apple.driver.AppleUSBCDC
sudo kextunload -b com.apple.driver.AppleUSBCDCACMData

Saw that and did it...without any luck. Was wondering first if anyone will actually confirm they are running a Bi•fury on mac successfully...otherwise I'll send it back.

Hrm those were the instructions for the bluefury. The bi*fury is something else. Not sure what driver it tries to install for those nor how to look it up on a mac etc.

I couldn't get my Bi*Fury on the Mac working either, and the only way to get it working for me on one of my Raspberry Pi's/Minepeon was to edit the /etc/udev/rules.d/01-miner.rules with sudo privileges and add an entry for the Bi*Fury with data from lsusb.

Details on what I did here: https://bitcointalk.org/index.php?topic=309918.msg3943685#msg3943685

The errors looked like a permissions issue in trying to access the device on both the Pi and the Mac and I didn't try running CGMiner under sudo on the Mac.  That could help.

...there's a udev rules file included with cgminer already

[xzempt]

anyway to use cgminer with blades yet?

Got it working finally with a Mac... switched from using a RPi...but I didn't use CGMiner to get it working with all the other devices I had on the Mac.

You may get away with just running CGMiner with sudo privileges to get it working for you.

How to disable Icarus while using Blue furys as had to use blues in cgminer and erupters in bfgminer.

Is their any way to get both working in cgminer ?

It must be a bug if you compiled with --enable-icarus --enable-bitfury and are unable to use both

[cunixion]

http://ck.kolivas.org/apps/cgminer/cgminer-3.8.5-windows.zip
website down 

maybe add you could add a mirror here docs.google.com
and please include to checksum just to make sure it's not modified after it got upload

Or just stick it on a Google Drive (or SkyDrive), set it to share to everyone, job done.

Bad idea.  I wouldn't trust an app placed on a google or skydrive.

why?

anyone capable could add a function to get your wallet details.

Hi there. I am here to report what looks to be a bug in cgminer. This bug manifests itself if you run cgminer pointed at the stratum port of the bfgminer proxy. This has been reported by numerous users, usually trying to point their KnC miner at the bfgminer proxy:

https://bitcointalk.org/index.php?topic=370365.msg3970326#msg3970326

To reproduce:

Code:

bfgminer --stratum-port 4444 -o some.miningpool.com -u worker -p password
cgminer --o 127.0.0.1:4444 -u doesnt -p matter

The output will repeatedly read:

Code:

Rejected a18df423 Diff 2/1 GPU 1  (H-not-zero)

I worked with Luke to debug both bfgminer and cgminer and he was able to make a few changes in the cgminer source to get accepted shares. Here is a summary of what he had to say:

cgminer is broken if nonce2_size is anything other than 4 (32-bit)
A proxy must always reduce the nonce2_size from the upstream server
BFGMiner always uses 2 (16-bit)
cgminer is memcpy-ing nonce2 with a fixed 32-bit size, even if nonce2_size is smaller
If you were to just memcpy the nonce2 with an adjusted size, it will fix little endian but break on big endian (to confirm the bug)

I'd really like to keep this civil and hopefully get a legitimate look at this bug as I am getting numerous users reporting it as I mentioned before. Thanks Con!
