I'm doing this on my laptop with an nvidia card (that is otherwise unused). It's running just fine, except sometimes the laptop overheats from the GPU and shuts down.
A better approach is to use the nvidia control panel to underclock the GPU core speed. Then vacuum the dust out of the fan hole and slots. And get a desktop PC before you solder-crack your GPU chip.

Even better than lowering core is lowering memory speed. Memory is hot.

Thanks for the suggestions and warnings, folks.

I'm running ubuntu, so the powershell doesn't quite cut it.

Now I'm running an additional script that just watches the temperature and pauses the oclvanitygen process when the temperature of the motherboard goes over 84 (and continues the process when the temperature drops under that).

I'm including a copy of the script, in the hope that it can help others that might be looking for a similar solution.

Code:
#!/bin/bash
OPID=$(pgrep oclvanitygen)
 
until [ 1 == 0 ]; do 
    TEMP=$(sensors|grep temp1:|tr -cd '0-9:.'|cut -f1 -d.|cut -f2 -d:)
    SIGNAL='-CONT'
    [ $TEMP -gt 84 ] && SIGNAL='-STOP'
    echo $TEMP... $SIGNAL
    kill $SIGNAL $OPID
    sleep 5
done

I have a problem: when i start oclvanitygen with 1something, unless to generate public and private key, vg generate a useless cpu and gpu hash...

How i can resolve?

Can you give the string you're using, and the output from the window?

Code:
oclvanitygen -p 1 -d 0 1something

And output like this:

Code:
Difficulty: 264104224
[22.86 Mkey/s][total 455081984][Prob 82.1%][90% in 6.7s]                       
Match idx: 0
CPU hash: 71682fec9bcafa7b1291c2cc09954692b716ca3e
GPU hash: 099bccd501a398a56eff31b40b924d8d9b132b72
Found delta: 4131272 Start delta: 1

I've started to experience this as well, I have concluded this problem is related to newer drivers (eg 13.xx). I had this card working great with v 12.8 Radeon drivers, as have many others.

I'm experiencing this as well.

Has anyone had problems with the OCL generator/miner crashing your system when you try to close it?

I'm running a GeForce 460 GTX with the latest drivers.  I can run the OCL versions just fine, that is, until I try to close it.  When that happens, one of three things will happen:

1. It closes just fine with no problems.
2. My screen goes black for a second, then comes back, and I get a notice on my system tray that my display driver had crashed, but it recovered.
3. My system hard locks completely.  Doesn't respond to key presses, any audio that was playing at the time does the machine gun effect, etc.  Only solution is a manual power-off.

#2 happens the most often, with #1 actually being somewhat rare.

Has anyone dealt with this and have any idea how to fix it?

samr7 doesn't seem to have touched his repo in a while.  I went ahead and forked his repo and merged in pretty much all the public branches on github.  I've done some quick tests, and there were no merge conflicts, but it's possible I combined some incompatible things.  

https://github.com/samr7/vanitygen/network has lots of pretty colored lines connecting to one branch now.  I also updated my OSX brew tap (`brew tap WyseNynja/bitcoin && brew install WyseNynja/bitcoin/vanitygen`) to include my branch of vanitygen which I tagged version 0.23-red.  It worked for me on Mavericks and it uses brew's openssl.  I added the red suffix just in case someone else has already done this and I just missed it in my cursory searching.

I see you pulled in (among other things) my compressed-key fixes.  Cool

I spend most of my time in Linux, but I had a request come through for a Windows build.  After tinkering with the makefile a bit, I got Visual C++ 2008 to build vanitygen.  The result is here:

https://dl.dropboxusercontent.com/u/57535575/vanitygen-0.23-red-win32.zip

oclvanityminer is not included, as libcurl was built against a different OpenSSL DLL than what was used for building the other tools.  If you need oclvanityminer, set up a Linux box...building from source on Linux is much easier than building from source on Windows.  vanitygen, oclvanitygen, and keyconv have been built.

Hmm. I'm not really sure.  I don't have a mac with a graphics card and haven't been able to test the opencl pieces Sad  I made an issue on github, lets continue this conversation there.  https://github.com/WyseNynja/vanitygen/issues/2

Do you have a precompiled OSX build of Vanitygen?
I can upload the one that I've built on my laptop.  No guarantees it's portable though.

I got that on OSX when it tried to build the .oclbin file (which it does on first run if the file does not exist) without being in the same directory as calc_address.cl.

I'm not sure how to resolve this on windows, but in OS X, that file is installed by my brew tap to /usr/local/opt/vanitygen/include/


nevrending I think the -D flag you are using is wrong.  Try this,

Code:
brew reinstall vanitygen
cd /usr/local/opt/vanitygen/include
oclvanitygen -d 1 -k 1111111

Hi Red Emerald

Thanks for your reply

I previously used samr7's vanitygen with the following command line
Code:
./oclvanitygen -D 0:1 -t 16 -w 256 -k <prefix>
Normally, samr7's won't compile oclvanitygen on OSX, so I modified the Makefile here and there, and It compiled oclvanitygen
It ran gracefully up until OSX 10.8.5

After I upgraded to OSX 10.9
It no longer runs Cheesy

I'm gonna try out your suggestions here and on GitHub and will report back the results Smiley

Also having the GPU hash/CPU hash error. I'm running Catalyst 13.11 and downgrading is not an option for me. Also AMD APP SDK v2.9, willing to downgrade this if this is the issue.

For those of you experiencing the hashes not matching issue, what solved the problem for me was to delete the OpenCL files for that newer version of Catalyst and to install an old copy of the 2.7 AMD APP SDK.
Here's the list of files I deleted:

C:\Windows\System32\amdocl64.dll
C:\Windows\System32\OpenCL.dll
C:\Windows\System32\OpenVideo64.dll
C:\Windows\System32\OVDecode64.dll
C:\Windows\System32\SlotMaximizerAg.dll
C:\Windows\System32\SlotMaximizerBe.dll

C:\Windows\SysWOW64\amdocl.dll
C:\Windows\SysWOW64\OpenCL.dll
C:\Windows\SysWOW64\OpenVideo.dll
C:\Windows\SysWOW64\OVDecode.dll
C:\Windows\SysWOW64\SlotMaximizerAg.dll
C:\Windows\SysWOW64\SlotMaximizerBe.dll

The 2.7 SDK I installed was the 32 bit version (I'm running 64-bit Windows 8 but my oclvanitygen is 32-bit). I'm guessing you only need to delete the files in the architecture of the vanitygen you are running.

For those who cant able to still run oclvanitygen, getting found delta, start delta.....
Just use driver uninstaller, i used this DDU from http://www.guru3d.com/files_details/display_driver_uninstaller_download.html.
unzip it in a folder in desktop, restart system in safe mode, run Display Driver Uninstaller.exe, select AMD-> Clean and restart.
It will remove all amd drivers & restart system.
Now just install 12.10 driver & everything works fine.

In theory: No. The software will not allow you to specific a pattern so specific/long. Yes, I tried it: for lulz. Why don't you download the program, tell it to look for a pattern eg. 10 characters long. Then make it 11, then 12... and so on while observing the time estimate to find a match... you will see what I mean quite quickly. Now, keep in mind that bitcoin addresses are usually 33-34 characters long.

In practice: Also no. It would take an impossibly long time. We're talking longer than the time the universe will likely exist for. If you know a loophole around that, please let us know. We should also stipulate a rule that to mention "quantum computers" you must at least have a masters/PhD in a relevant field.

Looking for a precompiled OSX build as well

get home-brew, then use
Code:
brew install vanitygen

I did that but got an error message:

Quote
Error: No available formula for vanitygen
Searching taps...

Then I saw a post by user Red Emerald that recommended:

Quote
brew tap WyseNynja/bitcoin && brew install WyseNynja/bitcoin/vanitygen

That worked well on my MacBook Air with OS X 10.9.1 !
