I've upgraded to windows 8 this morning, but now guiminer won't launch !

All I get is the icon in the taskbar for a few seconds, and it disapears. I have no error message, no windows, no error logs.

I have tried launching the app as an administrator, and in "windows xp" and "windows 7" compatibility modes.

By default it uses all the cores. This becomes a problem with multiple miners, on a quad core/etc. It uses 25% cpu for each card 4*25=100 load. If I set it to use core 0 only then i get 25 % for all 4 cards. I think this feature would work better if was set to 1 core by default. Took me a few days to figure this out, but alot of people have not and are maxxing out their CPU for no good reason.

Duplicate, sorry for that.
Please read: #56

Thanks.

My power is billed based on a time-of-use system. ie. my power is much cheaper overnight than it is during the day (half the price).
If GUIMiner could allow me to setup a simple schedule I could disable mining during weekdays and only mine weeknights/weekends and save quite a bit of money on my power bill.

I restarted my computer after some windows updates, but now I get this error when I try to mine using the slush pool:

The path for bitcoin is ok. I downloaded the new bitcoin 0.3.23 and the latest guiminer, but the problem persists. I can do solo fine. I don't know if they are related, but after the DDOS attack when I logged into my account, I saw this message:

Hi,

I'm using GUIMiner v2012-12-03

When I click "Save parameters", nothing happen. When I try to quit, "Do you want to save ?" => "Yes", nothing happen.

Where should I start digging ? Thanks

where is it?
and why when starting CUDA I have nothing? nada!
no log, no error , no nothing :(

ext path it is looking for it:
C:\Users\My.name\Downloads\guiminer-20121203\guiminer\miners\puddinpop\rpcminer-cuda.exe

i don't have folder miners !

Guiminer when deployed on Linux offers the option to create a Cuda miner, but the path points to a Windows .exe which of course is nonexistent.

The title say almost everything.

It would be really ni ce to have this feature, so we dont forget to start it when we start the computer.

In the console window, when I've replaced the poclbm.exe from 2012-02-19 packaged with GUIMiner of the same date with the poclbm.exe from yesterday's release (2012-09-20).

Not 100% sure that the balance will work, didn't look closely at the parsing code. My guess is it is something like changing confirmed to balance in the code, but you are the coder! An example of the JSON returned can be found at https://mtred.com/api/user/key/d0c3696e93e172c284fd1c818bee54b2

Hi,

When you select "Launch Bitcoin as a server," the program immediately notifies the user that it's ready to work. On my computers, it takes about 20 seconds before the Bitcoin server loads and creates connection. If you try to mine before the client it ready, guiminer gives a connection error message. Maybe the wording can be changed to tell the users to wait until the Bitcoin client is loaded and has connections. Also, new users may not know about needing to wait until all the blocks are downloaded before mining.

The program is working beautifully. I have it running on two computers, one with SLI. They ally have Nvidia 9800 GT cards. Each card is calculating 30 Mhash/sec.

I want to make a donation, but the link takes me to MyBitcoin site and I don't have any Bitcoins to send you right now. Do you accept Paypal?

I'm new to the GUI miner, and am having difficulty. When I try to start I see the error message no json object could be detected. Any hints on what I ma be doing wrong?

Hello,

I have an issue. I am running GUIminer with 2x ATI 5970s. The problem that I am having is that the Mhash rate will run for a few minutes at 300 mhash per core (1.2k mhash total) and then drop down to minimal (312 KHash) for no reason that I am able to troubleshoot. Do you have any idea why this would be happening?

Any help would be appreciated.

Thank you

I'm trying to set GUIMiner on my Windows Server 2008R2 box but when I start it it lists "No OpenCL device" in the drop down list.

I have an Intel Xeon E3-1230 proc and a Geforce 8400 GS card which isn't great but it's still compatible with CUDA and has the latest drivers installed.

Is it possible that it can't see the hardware because I typically log on to the server through an RDP session?

When I connect to slush's pool, I get the following error:

ImportError: No module named tools

It seems to be coming from ioutil.py in this line:

from serial.tools import list_ports

I'm running Python 2.7.3 on Linux Mint Maya. I haven't installed python-opencl since I don't have any GPU or CUDA. (In fact, when GUIMiner starts it says "No OpenCL devices detected"). I have installed "python-serial" and "python-numpy" already. Meaning import serial works but import serial.tools fails.

This error happens with latest code from master (as of today).

I'm behind a firewall and there is a squid proxy that I can use, but there is no configuration available to include address, port, username and password so it can connect through a proxy, as pools have http addresses.

Hi there

I just hacked together a little something that polls dbus and starts/stops mining when the screensaver comes on/off.

My editor removes whitespace at line ends so there's a few occurrences of that in the diff. This will of course only work on systems with dbus. Since I'm really not a python programmer I'd like to leave the task of making this safe for other platforms (e.g. disabled) and maybe adding a console switch to (de)activate this feature or add a checkbox in the gui and whatnot to you.

For my purposes, this is sufficient but I hope it might be useful to others and so am trying to contribute back.

Have fun!

With the latest 2011-08-23 release the "Accepted" column on the summary page seems broken (at least for slush/poclbm)
The pool actually accepts shares but they won't get listed.

Could you clarify something? When I look at my summary page, there is a column labeled Accepted, but there are two number listed for each worker. What is the number outside the parenthesis and the number inside the parenthesis? Same question for the Stale column.

If I have two cards running two different miners, do I need to register two different workers? For example, I joined slush pool and created a single worker. I'm using the single worker for both my miners. Is this right or do I need to set up a separate worker for each miner?

Thanks,
Ali

Also, BitPenny is closed indefinitely, so it should be removed IMHO.

When starting the GUI, I get a modal error:

"can't open file 'logo.ico' (error 2: No such file or directory)

I am sure it's there, the logo file, just not sure why I get the error. In addition, the system tray con is a blank white square. I assume that is due to the offending file.

I updated the software from 614 to 701 and my speeds fell from 32 and 30 to 24 and 22. I deleted 701 and reinstalled 614 and now my speed is back to 32 and 30.

I've remapped my appdata folder location, and when I try to start guiminner.exe I'm getting the error:

No such file or directory: 'C:\Users{me}\AppData\Roaming\Bitcoin\bitcoin.conf'

which is no longer where my AppData (and thus bitcoin.conf file) is located.

Can you use the %APPDATA% env variable instead?

Also, I often run a portable version of bitcoin-qt.exe where I specify yet another location for my bitcoin.conf file.

Would it be (or is it already?) possible to set the bitcoin.conf file location in an .ini file?

This is repeated over and over when a network connection is lost. Maybe poclbm should start (and notify about) an exponential backoff rather than just continuing to spam the logs every ~3s when connection is lost?

There is a virus reported by Avira in guiminer\miners\ufasoft\bitcoin-miner.exe. And the file is really bigger than the newest official ufasoft\bitcoin-miner.exe. Please check it!!!

Hi guys,

I noticed a Unicode Encode Error in guiminer. Iam just useing the newest Version (guiminer-20110824.exe).
What happened?
I entered my deepbit.net accountinformation and sayed "files->save". I also checked the "autostart"(checkbox) in the "summary" of this just entered new worker.
Then i closed the guiminer and want to start it again. The miner tries to load the saved settings and want to start automatically. The Problem is that i entered some strange ASCII codes for having a safe password. (containing i.e. #!?/_-ä)

Now?
I start the miner and get a error message: "error occured: see the logfile '***' for details"
here is the logfileentry:
Traceback (most recent call last):
File "guiminer.py", line 2283, in

I've tried running GUIminer on my custom pool that currently sends Getworks with Difficulty>1. Mining on it for a bit, I see GUIminer display notification of "1 accepted shares". Checking that claim against logs from Wireshark and console output of my pool, I can see that no data has been submitted along with the request. Only having mined more shares do valid Getwork results appear to be submitted. I'm guessing GUIminer claims any share with Difficulty 1 it finds to be both valid and automatically accepted by the pool, regardless of it even being sent to the pool for evaluation.

Hi,

When I stop the CUDA miner, my computer completly freeze and I cant do anything.

I can mouve the mouse cursor, CTRL-ALT-DELETE doesnt work, same for ALT-F4. I think that when I stop the miner, my Nvidia card simply crash and I have to restart my computer.

seems Slush's pool started mandating HTTPS for the API. Here's a potential fix?

from:
def requires_https(self, host):
"""Return True if the specified host requires HTTPs for balance update."""
return host == "mtred.com"

to:
def requires_https(self, host):
"""Return True if the specified host requires HTTPs for balance update."""
HOSTS_REQUIRING_HTTPS = ["mtred.com",
"api2.bitcoin.cz"]
if host in HOSTS_REQUIRING_HTTPS: return True
return False

Hi Kiv,

I've tried to Fork your Guiminer to support my Server. Unfortunately I didn't get the compilation of the Pythonfiles to work properly.

Everytime I'm trying to start the Guiminer it says:

Traceback (most recent call last):
File "guiminer.py", line 14, in
ImportError: No module named wx

its the import wx directive in guiminer.py that my eclipse doesn't understand... I now have 3 different Python Versions. 2.6, 2.7 and 3.2 and tried to use wx-28-ansi and unicode. none of them worked fine... do you know, how to solve this problem?

Thanks in Advance

Best Regards

Boris

By the way the guiminer.py in my Fork is allready updated to support my server, so If the solution for my problem is to complicated I would be happy, if you merge our versions and do an update of your software, so that my pool's api can be used.

For future upcoming pools it might be very usefull to set the different window settings (like if there is an api support or a withdrawal service) in a extra config file, or even in the servers.ini, so that you don't have to change guiminer.py everytime a pooladmin needs to support his features.

If I want to stop the GUIMiner running rpcminer-cuda.exe on a Nvidia Quadro FX 880M the computer freezes forever. Only a restart would solve the problem. My current workaround for this problem is to shut down the wireless conection and wait 1-2 Minutes. After that the stop button stops the miner and the computer doesn`t freeze.

Sadly I have no idea why this happens, just that it does. There appears to be recovery when this error occurs when running poclbm in DOS console, not sure if it will have other issues with the guiminer parser.

I am no way a strong python master, and I know nothing about OpenCL, but I did notice some things in the code that could "help" over wall.... I did notice a lot of:

if bla = "": or if bla != 0:
why not just do:
if bla:

I saw a lot of .sleeps commands... seems like a waste if the program is to run as fast as it can.

Also, I am guessing you did test, but how are you gaining anything from threading the code? Wouldn't the python GIL get in the way? I think you are better of writing some timer code if you are just wanting you sync the code in the matter that way it is all one big thread instead of smaller threads fighting for control.

Another option would to also coverent some python code using cython. I've seen hug jumps in speed when I did with in my own server (not a bitcoin miner).

Take what I said with a grand of surger xD Like I said, I'm no way a geru of python, and I haven't read all the code to understand how it all works yet. The code other wise seems clean.

It looks like there is a new address for slush to correct "connection" issues.

http://api2.bitcoin.cz:8332

It may be helpful to have the ability to change the address in the GUI. It seems like this pool changes its address regularly after DDOS attacks.

Thanks,
Ali

Hello Kiv,

first I well tell you you make a very good job...
I have a question for the guiminer...
can you make an option that the miner can connct trough a Proxy???

I have wahn to connet with clients (win XP) to a pool but i must connet with a proxy at work...
Thx an please give me a feedback...is that a parameter i must write in a config dat?

The miner is not starting a connetion....because the blockchain data is not connectet from me client Pc to the main server by the proxy 8080...

At this point poclbm just seems to hang, ctrl-c and running it again and the problem is gone but I seem to get this a fair bit and it may be the reason why guiminer just stops processing blocks for me frequently. Interestingly though poclbm on the command-line seems more stable, so maybe the hang issue is threading or subprocess buffer-related? My apologies for the somewhat mixed bug here :(

Is this possible (in current version) to see hash rate in log file? If now I would highly appreciated it - ex. to put new one value every 10 min. or so.

Because I would make a program to restart PC (or email notification) if hashrate is below some value or if it would become offline (or you can include it in GUIMiner - I can't help you as I don't know Python).

Hi, im new to the mining scene, and have tried setting up GUIMiner, but when i click start mining i get this error:

ValueError: need more than 1 value to unpack

Any ideas?
I have an account and worker with slush's pool and as far as i know ive set everything up properly.

Thanks

EDIT

Ok i re-opened GUIMiner, and re-entered my details but now i am receiving these error messages in this order:

No JSON object could be decoded

Failed to subscribe

IO errors - 1, tolerance 2

Ufasoft no longer ships (0.39) with bitcoin-miner.exe / bitcoin-miner-64.exe, and instead uses coin-miner.exe

This means GUIMiner fails to start mining, as it relies on seeing 'bitcoin-miner' in the external path.

I temporarily got round this by renaming coin-miner.exe to bitcoin-miner.exe, but I think guiminer.py needs to be updated to reflect this.
