I finally got this to recognize my 6950 and it is hashing around half the rate of the CPU, I thought GPU's were meant to be faster for mining?
GPU - 240Kh/s
CPU - 540Kh/s
Is there anything I can do to make the GPU faster short of overclocking the card?   Huh

GUIMiner closes if I click the icon. The window does not appear after launching. How do I get it to work?

I've run into this problem, the app crashes because you have a problem with your Driver/opencl.

Simply uninstall opencl package, then driver package, then run driverfusion to sweep leftovers(very important). Reboot.
Reinstall drivers, then opencl, Should launch now.

If you are not talking about app crash, but no visible window, thats different.
In win 7 simply hover over the app in taskbar right click and maximize, then pull down the top bar to relocate the app on screen.

Hello, I can only find one place where this qestion is asked and no one is answering it. I've just started getting into bitcoin and I know I set up guiminer correctly but I keep experiencing:
Code:
2013-12-11 23:36:48: Listener for "BTC Miner 1" started
2013-12-11 23:36:48: Listener for "BTC Miner 1": Traceback (most recent call last):

2013-12-11 23:36:48: Listener for "BTC Miner 1": NameError: name 'OpenCLMiner' is not defined

This is really frustrating because I have no clue what the heck to do since I am so new. I have the Nvidia EVGA GTX 550 ti 1gb graphics card on Windows 7 64-bit. I'm trying to use Slush's pool and have my worker and wallet all set up. I've seen videos of the miner working and I love the set up and the way it works, but I just need it to work. Any help would be very appreciated as I am very eager to get to money and will be sure to donate some of my profits to you for your help, thanks!

Update: after a night of sitting, the miner gives me this in the console:

Do you have the Cuda pack installed? You will likely need it if using a nVidia GPU.

A side note: you may not get a very good speed from nVidia hardware, especially when going for BTC. An ASIC device would be much more effective at this point.

I am using this with a NVidia GT450. The default OpenCL works (at 42-43 Mh/s), but CUDA doesn't.

LE: I found how to do it. It makes only 36Mh/s.

I'm not sure with Cuda. Like the guy above me^, I do have GPU Caps Viewer and can send a few pictures of that if needed. Where do I find this out and where would I acquire it?

In response to the side note, I am for Christmas. I'm undecided on what I should get. Any ASIC going for around $500. Is the return of investment a decently short period of time given current prices. What do you recommend and what have you heard. I'm eager to learn all I can. And thank you for responding, glad to see this thread active!

Hi,

I have a problem with the integrated guiminer of GRC.
I don't know, if it's really a problem, but want to be shure.


After a couple of time my grcminingconsole shows:



instead of:


Now my question,
is the guiminer working when the screen does not show the actuell hashing rate?
Every time I see this, I'm restarting the miner, but I can't watch it the whole day and start it every time.
But is it really neccessary to restart it or, does the miner still works?
I can't see if the graficcards are working when it happens ( so I couldn't conclude if the miner works or not), because I'm using the pc via teamviewer.

Hope you can help me with my questions.

I am just starting with GUIMiner, but am not sure how to tell if it is mining or not.

I do not get the screen shots you showed in your post.

My interface appears to be just the main page where you log in. I selected slush's pool.

It shows me the hast rate (36.6 Mhash), and shows that I accepted 3 shares.

Even though I do not have the nice screen like the poster above me, am I still mining?

I am very new to OpenCL and just successfully installed the AMD ADD SDKS module/driver/software onto my 8GB RAM, Intel Core i7-2630QM CPU @ 2.00GHz laptop, running Windows 7 with a ATI Mobility Radeon HD 6570 graphics card. After what appeared to be a successful installation, the GUI Miner application continues to say that "No OpenCL devices were found." Is there a procedure to "activate" the AMD APP SDKS software? Is there a utility that exists that can be run that would determine whether the software was properly installed and ready for use? These may sound like questions from a novice, but that's because I AM a novice. I appreciate the assistance from someone with expertise in this area. Huh

Your gpu should not and possibly can no longer be used used for mining. Even back in 2011 this gpu was so inefficient it would not create enough hashes to pay for its own power costs. You might have not submitted a single share as diff is way to high for such small hashrates. Might as well play the lottery and solo CPU mine bitcoin at this speed. (hint: it's a waste of power and you will likely not earn anything in 500 years)

Mine DigitalCoin or some other scrypt coin, but even that would be a waste with your gpu. It's much better used for gaming.

The software has a big issue. In my box with 64 cores, and I have another one with 80 cores, the GUI does not show the right hand side, where the user name goes.
I am  doing CPU mining only.
Could you please post a version that has a more convenient GUI for boxes that are not desktop consumers but servers wit several dozens cores?
I can send you a donation if you can do this for  me, including connecting it to https://btcdig.com

Hello All,

I'm a totally newbie and I'm starting from scratch so please sorry if my questioins are silly  Embarrassed

I followed this guide: http://cryptocur.com/bitcoin/bitcoin-mining-guide/ (found there the link to this forum), I downloaded the AMD-APP-SDK (64bit) for my graphic card ATI Raderon 6700 series and install it.

I wish to mining Dogecoins so I joined a pool, but I can't start mining with Guimining! I set up the software in this way:
 
  • Server: I choose 'other' from the window
  • Host: I put the stratum address
  • Port: the port gave me by the pool
  • Username: my worker user
  • Password: the password of my worker
  • Device: I have only two options: Juniper or Intel core i5 2400, I choose the first
  • Extra flags: I really don't know what is it, so I leave it empty
  • CPU affinity: 0

Then I click on 'start mining', it says 'Starting', but this error appears: 'Value error: need more than 1 value to unpack' what does it mean? Above all, what should I do?

I try to set the cpu affinity on 2 or 3, but nothing happened. I have a windows 7 home 6.1.7601 service pack 1 build 7601, x64 based, CPU intel core i5-2400 @3101 mhz, 4 core with 4 gb of RAM and ATI radeon 6700 series as graphic card, help please  Huh

Thank you, bye.

Taking my first step into Bitmining tonight and it seems GUImining is serving as a roadblock for me already. So far my total progress is a crash on launch.

Right now I am making use of an above average laptop while I try to get my foot in the door and learn how this all works. The graphics card it sports is a Radeon HD 7470M with a i7-2670QM hyper-threaded quadcore on Windows 7 64bit.

I am unsure how "efficient" this machine will be and at the moment I am more interested in getting the software working before debating the hardware.

Hey everyone, I've created a Windows GUI for mining Bitcoins using your GPU or CPU.

This is the easiest way to get started mining on Windows. No messing around with the command line is required, and it has several features beyond what command line miners provide. The GUI is free and open source, but if you successfully use this program to generate coins, I would appreciate a donation, no matter how small.

How to Donate:

Please send donations directly to: 1MDDh2h4cAZDafgc94mr9q95dhRYcJbNQo

Most donations I receive are less than 0.1 BTC, so please consider donating even small amounts if this program helped you out.

Features:
- Comes already configured for many popular pools. No need to enter in URLs and ports manually unless you want to. Can automatically fall back from a primary pool to a backup pool.

- Real-time statistics on all your running miners in one location. Displays hash rate, total shares accepted/invalid, and total shares in the past hour.

- Automatically start one or more miners on program startup.

- View your account balance with a pool and/or withdraw funds from within the GUI, at participating pools.

- Minimizes to tray. The tray icon can be hovered to show statistics, and miners can be paused from the tray context menu.

Screenshots:
http://dl.dropbox.com/u/2046348/poclbm-summary.pnghttp://dl.dropbox.com/u/2046348/poclbm-minertab.png

Download latest version (Windows):
    
    (self-extracting archive)        

Older versions:

    (self-extracting archive)    
     (self-extracting archive)
    
     (self-extracting archive)
    Archived versions

Running on Linux:

Support for this is still early but some people have reported success. To install it on Linux:

- Get the source code from GitHub either using Git or by downloading one of the archived source versions.
- Install OpenCL drivers and PyOpenCL. These are the same ones you need to run poclbm so if you search on the forums you can find guides for this.
- Install wxPython; your distribution's package manager should have this.
- Run guiminer.py to start the miner. This will let you mine using OpenCL/poclbm (the default mode). You'll have to compile the other backends separately if you want to use them.

If you do get it running, send me a message and let me know of your experience. I might make a separate topic about it if people are having trouble.

How to use:

Extract the archive to anywhere (your desktop is fine) and double click the guiminer executable. If you have OpenCL set up correctly this should launch the GUI. If you get an error about OpenCL, you need to install an OpenCL package from your GPU vendor. For AMD/ATI cards you can get OpenCL here.

Once the GUI is running, choose a pool and register if necessary from the pool website, then press "Start mining" to begin. Wait for the coins to come in and don't forget to donate Smiley

How to use a backup pool aka fallback support:

Fallback support is in the OpenCL miner only. In the flags, specify the info of the backup pool or pools. For example if I want to fallback to my account on slush's pool, I would write:

Kiv.GPU:mypass@api.bitcoin.cz:8332

If you don't know the host name or port, you can see it in the console tab whenever you run a miner.That's all you need for basic support. You can tweak it with these options:

--failback=N   attempt to fail back to the primary pool every n getworks, default 2
--tolerance=N   use fallback pool only after N consecutive connection errors, default 2

In the future this might be more tightly integrated into the GUI but I don't want to make the GUI too complicated for things that a lot of users don't need.

How to get help:

For technical support please post in this thread rather than sending me a PM; this will get you a reply sooner since other people than me can help you out. More information is better; with only a brief vague report we probably don't know enough to pinpoint your problem. Here's an example of a good report:

"When I try to start mining, I get "Problems communicating with bitcoin RPC" in the status bar and the miner doesn't start. I already checked that my bitcoin.conf contains the correct username and password. I am using:

GUIMiner version: v2011-06-09
Operating system: Windows XP SP3
Miner backend: OpenCL/poclbm
Video card: ATI 5770
Server: solo mining on Bitcoin client 0.3.22

Frequently Asked Questions (FAQ):

Q: My window is invisible! What can I do?
A: See here for a solution.

Q: Help! The program crashed or didn't work!
A: If you post a bug report in this thread a variety of helpful people including myself can try to fix your issue. We need to know at least the following: what version of Windows you're using, what graphics card you're using, what version of drivers you're using, what pool you're using if applicable, and a detailed description of what went wrong.

Q: I get an error about "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem." or an error mentioning "side-by-side". What can I do?
A: You may need to install the Microsoft Visual C++ 2008 Redistributable Package. Nearly all Windows computers already have this installed, but a freshly formatted computer might not.

Q: I'm having trouble solo mining using the 0.3.22 Bitcoin client. Why?
A: This is a known issue, see this thread for more info. Reverting to 0.3.21 or earlier seems to fix the problem.

Q: How do I know if my graphics card (GPU) supports OpenCL or CUDA?
A: Try running GPU Caps Viewer. It will tell you what your GPU supports.

Q: How do I use the Phoenix/phatk miner?
A: See this thread for support.

Q: What extra flags do I use?
A: If you have a Radeon 5xxx card (for example 5770, 5890), use '-v -w128'. On CPU you don't need any flags. For other cards ask around.

Q: My temperatures are too high, can I throttle the GPU so it runs slower but cooler?
A: If you are mining using OpenCL you can use the -s flag a value such as 0.01 in order to force the GPU to sleep for 0.01 seconds in between runs. Increase or decrease this value until you have the desired GPU utilization.

Q: Can I connect to more than one pool with the same GPU? For example have a main pool, and a backup pool in case the main one goes down?
A: Yes, you can use the -f flag for this. A value of -f60 or higher in the backup pool's miner will cause it to yield most of the GPU power to miners with a lower f value (default is 30).

Q: Is it normal that GUIMiner uses a lot of CPU when mining on the GPU?
A: No, for most people GUIMiner uses less than 1% of CPU. This is a poclbm issue some people are experiencing - see this post for more info.

Q: Do I need the official Bitcoin client to be open while mining?
A: Only if you are doing solo mining - in this case you are connecting to the client instead of a pool server.

Q: Is there a tutorial for solo mining?
A: Yes, see this thread.

Q: How does performance using the GUI compare to using the command line?
A: They should be identical; the GUI introduces virtually no overhead.

Q: How do I know if I'm getting a good hashing rate for my card?
A: See this topic for a comparison of various cards.

Q: How do I know how many Bitcoins I'll generate with my card?
A: See Bitcoin Mining Calculator to determine this.

Q: I installed OpenCL, but my GPU isn't showing up. Only my CPU is shown. What is the problem?
A: A couple people experienced this issue and were able to resolve it by installing a different driver version. Another person resolved it on Windows XP by upgrading from Service Pack 2 to Service Pack 3.

Q: How can I delete my miner settings, or edit them manually?
A: Miner settings are stored in %APPDATA%\Roaming\poclbm. For example, on Windows 7 this path translates to C:\Users\Kiv\AppData\Roaming\poclbm. The file poclbm.ini inside contains the settings in JSON format. There are also some settings in .ini files inside the miner directory, also in JSON format. No registry keys are used, so removing these .ini files completely erases your settings.

Q: How can I completely uninstall GUIMiner?
A: Remove the GUIMiner folder and the miner settings above, and that will completely remove GUIMiner.

Q: I want to see X feature in the miner. How can I have it?
A: I'm working on new features but I have a full time job and other things to do too - if you want to encourage me send donations to: 1MDDh2h4cAZDafgc94mr9q95dhRYcJbNQo

Q: What does it mean in the summary panel when the shares say something like 1000 (150) accepted?
A: That means 1000 shares total were accepted, including 150 in the last hour.

20121118
- Update poclbm to latest miner including Stratum support.
- Fix rejected/stale counter not incrementing properly.
- For solo mining, accept bitcoin-qt.exe or any other *.exe file for client instead of just bitcoin.exe.
- For solo mining, add option to set bitcoin data directory, in case it's not in the default location.
- Remove Phoenix 1 support since it's no longer maintained.

20120219
- Include latest poclbm code with critical bugfix.
- Various updates to translations, pools, etc. from various contributors - see GitHub commit list for a complete list. Thanks to all who submitted patches!
20110824
- Fix accepted shares not being recognized under the newest poclbm version
- Fix balance not being recognized for slush's pool
20110823
- Update poclbm (OpenCL miner) to the latest version. This changes the format of a backup pool. In the "extra flags" you just enter your backup (or backups) like this: Kiv.GPU:mypass@api2.bitcoin.cz:8332
- Update Phoenix to the latest version. See their thread for details on changes.
- Remove ufasoft miner from the GUIMiner bundle. It's still supported, but you'll have to download it separately. I apologize for the inconvenience to ufasoft miner users, but I decided to do this since only a few percent of users were using ufasoft and due to recurring false positive issues from antivirus programs.
- Added "duplicate miner" option when right clicking on a miner tab. This is to make it easier to clone miners to multiple GPUs.
- Limited maximum scrollback in the console window to 5000 lines. On machines with low RAM, this will prevent running out of memory after a long period of continuous operation.
- Add more pools to the server list, though balance update doesn't work for all of them. I'm looking at ways to handle the large number of pools that are popping up better.
- Fix Linux bug where the window could not be restored after minimizing.
20110701:
- Updated poclbm (OpenCL miner) backend to the latest version which has built-in fallback support and slightly
improved performance using a modified phatk kernel. Big thanks to m0mchil and all who submitted code for this. This version should be a few percent faster on most graphics cards.
- Update Phoenix backend to version 1.50.
- Add many more pools to the server list, including separate servers for BTC Guild.
- Default CPU affinity changed to be CPU 0 only instead of all CPUs.
- Display of GHash shows more decimal places (requested by hawks5999).
- When you save miner settings it remembers the GUI size and position for future runs (requested by goozman96).
- Removed weird characters in console log of Phoenix miner.
- Error handling: If settings file could not be read, recover gracefully instead of raising a JSON error.
- Error handling: If no OpenCL devices exist, recover gracefully instead of raising AssertionError.

20110614:
- Slush's pool moved from mining.bitcoin.cz to api.bitcoin.cz. If any miners on slush's pool cannot connect, you should delete and re-create the worker to make sure it's using the new address.
- Add CPU affinity support, meaning miners can be assigned to a specific CPU core. Users seeing the 100% CPU usage when mining with OpenCL due to buggy drivers can reduce their CPU usage by allowing the miner to only run on a specific core.
- Fix error about missing logo.ico.
- New Italian translation, big thanks to MasterHunterHD for contributing this.
20110609:
