Create vanity bitcoin addresses four times as fast

[lifeboat]

I'm going to try for a 9 character custom

It's possible. At https://lifeboat.com/ex/bitcoin, we say "Become a Lifeboat VIP and donate to bitcoin address 1LifeboatVPg24QghZ73Dzrx8AxcJLCnoA".

[ricolein]

Hi,

there are not all characters allowed? I got this message:

   Invalid character 'l' in prefix '1Elisa'

I tried booth CPU-versions with command line

  Vanitygen -F compressed -f adress.txt -o AdrBTC.txt

Even if i try other word contain 'l' i got this message. This is a funny bug...

Ciao

In BTC addresses u can't use the letters l (lowercase), I and O (uppercase).

LTC addresses -X 48 starts only from LK... and ends Li..., so be aware of second character

DGC (Digitalcoin) addresses -X 30 must start with uppercase D and a number or uppercase letter for the second letter/digit of the pattern also.

[ricolein]

In BTC addresses u can't use the letters l (lowercase), I and O (uppercase).

Yes, of course. For better spelling...

Can someone explain for what is option -P? Sounds interesting, but i have no idea how to use. Even some useful links are welcome.

Btw, nice profile pic!

Here is Catalyst 12.10 files to fix the issue with oclvanitygen.exe on 7### series of AMD/ATI Radeon on Win7x64 systems.

Code:

Just unpack and copy files to your windows dir, or run .bat files under Administrator.

Tested it on Radeon 79XX and found it working perfectly @ 27Mkeys/sek.

Thank's !!!
Tested it on Radeon 6990/win8-64bit and found it @ 34Mkeys/sek

Thanks, lifeboat! I was able to use this on my 6950 after downgrading to catalyst 12.10 mentioned a couple of posts up.

Is there any chance you can build oclvanityminer64 as well? I'd be happy to donate some of the profits if I ever find any!

I thought I had managed to build it, and ended up with a (32bit) binary, but it just wouldn't run (Windows error saying "The application was unable to start correctly (0xc000007b). Click OK to close the application"). I had some issues building libcurl, I think that's where it went wrong. The readme doesn't mention it and it's just assumed in the makefile... I haven't dabbled in that area of programming in a number years, so I could be forgetting something pretty simple.

Or if you didn't want to build it for me but have an idea what I'm doing wrong, I'd happily accept some advice!

[BitDreams]

Mine is probably in poor taste but there's a story behind it.

You probably have a mixture of 32 and 64 bit files. You want to be sure that all DLLs are the same bit width as your .exe. You also want to be sure that your libraries are of the same bit width. And yes, this can be a pain-in-the-butt to pull off. (In our http://lifeboat.com/oclvanitygen we had to rename our 64-bit version of libeay32.dll to libeay64.dll and then alter oclvanitygen64.exe and vanitygen64.exe so they looked for libeay64.dll instead of libeay32.dll. If we didn't do this they would try to use the 32-bit version of libeay32.dll and crash.) If you make a donation at https://lifeboat.com/ex/bitcoin, we would be glad to put some effort into oclvanityminer64.

[btcpleb]

Unfortunately I cant afford to donate at this time, unless you'd accept about 6 cents worth of bitcoin unless you would accept a feathercoin I mined

Thanks for your tip, I managed to build through Cygwin (way easier and I felt a bit more at home) but my oclvanitygen is doing the mismatched CPU/GPU hash thing (even with the change in the github issue, but to the compressed_opencl branch). I suspect this is because I statically linked the APP libraries (your version worked flawlessly with my DLLs). I'm going to try downloading archived versions of the APP libraries and see if they work before trying to dynamically link them (I don't want a catalyst/APP upgrade to break compatibility).

Edit: I've managed to get a 32bit version working perfectly. Not sure I'll bother spending time to get a 64bit version. Happy to share on request.

[zhinkk]

Having a strange issue. I run:

Code:

vanitygen 1a

And it generates an address with "1a" INSTANTLY. It says difficulty is 1353.

Then I run:

Code:

oclvanitygen.exe -d 0 1a

(difficulty 1353 still)
It shows over 10 Mkey/s but even after 5 minutes it can't find a address with pattern "1a". Why is this?

I'm using Catalyst 13.11. I didn't install any seperate SDK's so I'm guessing I'm using the ones that came with it. The kernel DOES compile though and the oclvanitygen program still runs. Does this mean I have to install the SDK? I thought if I didn't have the proper SDK it would just crash, not a situation where it can't find a patterned key.


You can see the verbose output here:

If you see CPU hash or GPU hash, that means it is broken, so you can kill the program immediately if you see that.

Healthy output of oclvanitygen looks like this:

You'll need to install the old Catalyst 12.10 drivers for it to work.

I have 13.11 catalyst but I installed the 12.10 SDK (I think) using the batch file in this post:

Here is Catalyst 12.10 files to fix the issue with oclvanitygen.exe on 7### series of AMD/ATI Radeon on Win7x64 systems.

Still getting the problem.

[zhinkk]

Wooot! It's working now! I uninstalled the 13.11 drives, ran the batch script by lifeboat on the 3rd page, and installed 12.10 drivers. I'm now getting over 22 Mkey/s with my Radeon HD 6870!

[Jcw188]

Do people actually buy and sell vanity addresses?  I guess that's pretty cool.  It seems like it would take a long time to get some useful addresses.  DOes anyone have any other interesting vanity addresses?  what's the deal with getting 1Lifeboat, why is 1 Lifeboat important?

[jongameson]

My computer is a I5 Windows 8 64, with 1 7870 and 1 7950. Both cards works but always repeats the message GPU and CPU hash, without end.

It sounds like you didn't completely uninstall your Catalyst drivers. (It is tricky to downgrade.) To complete your uninstall, run the following batch file:

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

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

rmdir C:\ProgramData\AMD\KDB /S /Q

After running it, install the Catalyst 12.10 drivers.

does not work, I don't even HAVE a C:\Windows\SysWOW64 directory or a C:\ProgramData directory

tried uninstalling 13.11 running this, and installing Catalyst 12.10 and no go
still CPU and GPU hash messages

Well I wouldn't have enough trust in someone to buy a vanity address off them. They would have my private key and they could access my coins anytime.

Hi Lifeboat.

The problem is that for the new cards R9 280x you need the latest Catalyst Drivers.

Just getting CPU and GPU hash messages. So Im just running this off CPU at this point. 1.3MH/s instead of 30+ MH/s per GPU

Let me know if you guys know what we can do about this.

Thanks again for great software.

The key is to delete any OpenCL.dll files on your machine. And then to install Catalyst 12.10. If this works, let me know the locations of the OpenCL.dll files that you deleted.

[lifeboat]

The problem is that for the new cards R9 280x you need the latest Catalyst Drivers. .

Uninstall those drivers, then run amdclean.bat which is:

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

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

rmdir C:\ProgramData\AMD\KDB /S /Q

Then install http://developer.amd.com/amd-license-agreement/?f=AMD-APP-SDK-v2.7-Windows-641.exe

Then do a selective install of the latest Catalyst drivers, making sure you don't install any more AMD APP SDK drivers.
