Vanitygen: Vanity bitcoin address generator/miner [v0.22]

[retrend]

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

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.

same problem - how do i fix this?

I've got the same issue, is it a driver problem?

All I get is:

Invalid character 'l' in prefix 'oclvanitygen'
Invalid character '-' in prefix '-p'
Invalid character '-' in prefix '-d'
Invalid character '0' in prefix '0'
Prefix '1something' ignored, overlaps '1'

Can someone help me?

I figured it out I have to do -p 0 first then -d 0.  The video card is 3.75 times faster then my cpu it seems.

I've got the same issue, is it a driver problem?

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.

ATiMan Uninstaller also works really well. It's actually amazing to watch all the things it does.

oh one other Q, is it possible to use the generator for altcoin addresses? I assume yes, but in that case I assume one has to modify the source code?

No you don't need to.
This subject has been discussed in this topic. U have to use option "X" with the code of the coin.

Something like this: vanitygen -X 48 -o addys.txt LTCmis
The same for OCLVanitygen...... Be aware to state as first and second letter according with coin specs

For LTC: 48
FTC: 14
NVC: 8
ANC: 23
PTC: 47
CNC: 28
DGC:30
NMC: 52
PPC:55
YAC: 77
BQC: 85
IXC: 138
DOGE: 30

What "x" for ZET?

I don't understand how to run oclvanitygen.

If I type in "oclvanitygen -v -d 0 1a" I keep getting GPU and CPU hashes.

EDIT: nvm I got my address with vanitygen64

You have a bad driver. Read previous pages.

[crazyearner]

Anyone know how to generate addresses with gpu I keep getting hash found bla bla bla list of numbers but no produced bitcoin address

oclvanityminer am using works and woks on gpu however no produce Bitcoin address any idea how to fix.

Well if the previous comments are any indication:

i) You are using incorrect commands. Post your commands you are using?
and/or,
ii) You are using an incompatible driver version. Try using compatible drivers such as 12.8, and use a driver uninstaller when changing to earlier versions.

finally managed to run vanitygen on my mac with this simple and well explained article:

me happy

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.

Now just install 12.10 driver & everything works fine.

Because the software has not been largely updated since it was written, which is when opencl 1.0 was just transitioning to 1.1.

OpenCL apps have not yet become generic, they almost have to target a particular card and driver, since driver updates keep breaking things.

Here is an interesting topic - below are the only ATI HDXXXX GPUs that support double-precision math. It would be interesting to see if the computing problem on new drivers varies based on this card list:

HD 5830 HD 5850 HD 5870 HD 5970

HD 6930 HD 6950 HD 6970 HD 6990

HD 7730 HD 7750 HD 7770 HD 7790 HD 7850
HD 7870 HD 7950 HD 7970 HD 7990

I have a 5770, and vanitygen works fine (and first worked correctly) using Driver 11.11, which includes the SDK 2.5 runtime. It doesn't work on any later drivers. One conspiracy theory could be that other OpenCL computing features were disabled on single-precision cards in later drivers.

Here is a list of each first driver version that included a new SDK. You must also be aware that the ATI uninstaller does not properly uninstall key OpenCL files. If you want to experiment, you should increment starting with older versions, so you don't have to manually delete left-behind files each time.

AMD APP SDK v2.9    AMD Catalyst™ 13.11 beta (13.20.16)
AMD APP SDK v2.8.1    AMD Catalyst™ 13.6 Beta2 (13.101)
AMD APP SDK v2.8    AMD Catalyst™ 12.10 (9.002)
AMD APP SDK v2.7    AMD Catalyst™ 12.4 (8.961)
AMD APP SDK v2.6    AMD Catalyst™ 11.12 (8.92)
AMD APP SDK v2.5    AMD Catalyst™ 11.7 (8.872)
AMD APP SDK v2.4    ATI Catalyst™ 11.4 Update Driver (8.841)

I had tons of problem on Win 7 64, no matter what I did, but with http://lifeboat.com/oclvanitygen and getting rid of all the files like I quoted from above here, plus installing "AMD Catalyst™ 12.10 (9.002)" with the SDK in it, works like a charm. Getting 25 Mkey/s on my ASUS HD 7950 CU-II.

Thanks!

I have a question about this program.

If I set this up to run on a offline system and generate addresses, Can i send coin to the new address or do I have to load the private key to a wallet and since it before it will work. So can I keep these keys offline until I want to drain the address?

Correct, if you generate the private key, you can send funds at any time to the public address. you only need to import the private key when you wish to spend the funds.

im getting this:

Error loading kernel file 'calc_addrs.cl': No such file or directory

ive been trying out why! any help is appreciated! using my GPU and everything works fine til that point

Can it utilize multiple GPUs?

Available OpenCL platforms:
0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing
  0: [Advanced Micro Devices, Inc.] Tahiti
  1: [Advanced Micro Devices, Inc.] Tahiti
  2: [GenuineIntel] Intel(R) Celeron(R) CPU 2.80GHz

-d 0,1 didnt work, -d 0 -d 1 neither ^^

Another fun fact, my 7950 seems to be just as fast as my 5850 - around 20 mkey/s

[foroplus]

Try something like this: oclvanitygen -D 0:0 -D 0:1 -v -F compressed -d 1 -o matches.txt 1EnJoy

For me it's working. Both cards are working and the hashrate is the sum of them.

A 7950 can work at 24-26Mkeys.

Run 2 instances of the command window.

You can open a command window at the correct folder path by Shift+Right clicking a folder in Windows and clicking the hidden menu item: "Open command window here", then use the square in the top left of the window to access copy/paste commands. Keep a document open to edit your command parameters (-d) for your different GPU's. Chances are you'll make lots of adjustments to the commands you use anyway.

Another fun fact, my 7950 seems to be just as fast as my 5850 - around 20 mkey/s

Check the GPU is at 99 or 100% load with something like GPU-z or MSI Afterburner. If it is not, run multiple instances of the command window on the same GPU. This has all been covered in the previous pages of this thread but it's grown a bit too large now.

Tell me in detail how these vanity address work ?

Who: GPU owners
What: Addresses with specific patterns, like names, in them. Refer my signature.
When: Since OP
Where: Your GPU's core and memory chips
Why: Because it looks cool
How: It uses your GPU (or CPU) to randomly generate private keys and their derived public key ("address"), discarding all of them except the ones that match the pattern you've entered. You then import the private key (and hence the address you wanted) into your wallet software.
