There are 225 forks of samr7's original version, which you can see here: https://github.com/samr7/vanitygen/network . Kangaderoo's version isn't a real fork in github's view and it has 0 people following it. So how is his version more trustworthy? Also, his version doesn't even compile on OS X.
I wouldn't say 'more trustworthy' - just more recent, includes various other fixes.  You can check if the basic generation code is still the same Smiley

Such as? The only other methods I know of are messing with the keypool from bitcoin core and using the bulk option from bitaddress.org, neither method lends itself to programmatic usage.
The bulk option from bitaddress.org is still just basic javascript - a fairly decent path for programmatic usage at least if the language is javascript.  Bitcoin-core should also be accessible via json-rpc.
There was a discussion on mass-generation of keys/addresses earlier, but I don't think that really led to a specific utility conclusion (organofcorti was on the verge of getting bored enough to write one, though).

Weird.  I'm not even sure how it came up with those even from the invalid input WIF keys.  Some tools come up with 167LRjJf1r6VAV8FmyXsgUnLWnS9FUE13C for the first one because they're probably not verifying the input correctly.  It's supposed to check the first byte, the last 4 bytes (checksum), and take the remainder.  Instead they seem to be checking the first/last four just fine, but then additionally trim the remainder to 33 bytes.

Yeah! I start cmd.exe as administrator and now all works (oclvanitygen too)!
Big thanks TheRealSteve!


38 Mkey/s it's normal for GTX 970?

I am getting around 4 Mkey/s on a r7 240 so that seems to be about right for a 970

God, I had no idea you knew me and my inadequate attention span so well.

I ended up just using a script to run vanitygen with the "1" prefix, save everything and regex every n addresses and save the results to a file. I left it a few weeks before I looked through the results.

Thanks for the figures - I've added them to the wiki entry for vanitygen; https://en.bitcoin.it/wiki/Vanitygen#Expected_keysearch_rate

Might trawl through thread to look for some more, but generally more recent hardware tends to be more interesting.  If you'd like to add to the wiki directly, go ahead and register and either pay the editing rights fee or request editing rights manually:

I've looked back many pages but I couldn't find anything.
Has anyone created and compiled a Windows 7 version of Vanitygen that works with AMD 290's?

The oclvanitygen offered here should be appropriate for your system. You might need to install OpenCL/AMD Parallel Processing drivers.

I've attempted to use it in the past for newer AMD GPU's with no success.

Have there been code changes?

I can only get it to work with 5xxx & 6xxx GPU's.

Nvidia cards are like that. I get that too.

If you use NVIDIA hardware, CL_OUT_OF_RESOURCES is a kind of "generic" error returned by the driver when something is wrong. As a result, it is not necessarily a real "Out of resources" problem.

For instance, calling clCreateFromGLTexture2D() with an invalid texture ID will often return CL_OUT_OF_RESOURCES with an NVIDIA driver whereas it will return CL_INVALID_GL_OBJECT with an AMD or Intel driver.

If you are having trouble with AMD video cards search for Lifeboats version of oclvanitygen.

It worked for me right out of the box on my 7950 and R9 270.

If anyone wants to make a quick(ish) ~$200, I'm looking for a couple of vanity addresses:

I am getting 50-55 Mkey/s with 2 r9 280x's using oclvanitygen. On one of them I am able to push 30-35 Mkey/s, I assume the lost hash is from the other one running the monitor.

Anyway if you wanted to add that to the specs part  r9 280x = 25-35 Mkey/s.

I also recently updated the Vanitygen article in general with some general info on pattern difficulty and any delusions of trying to use Vanitygen to attack addresses Smiley

I would like to say a gtx 780ti does 50-60Mkey/s highest was 62Mkey/s

just for documenting purposes.

I saw in another thread that someone is able to get 5+ Mkey/s out of their laptop with oclvanitygen.  I am sure I am doing something wrong with the parameters trying to get it working, still only getting about 100 Kkey/s using these parameters:

oclvanitygen -f list.txt -D 0:0 -w 512

on a Lenovo laptop with 64bit Win7.  According to oclvanitygen I have:
0: i5-3320M CPU @ 2.60GHz
1: Intel HD Graphics 4000

Can anyone share what are your typical input parameters or provide pointers?

There is no "certain" parameters to boost your speed. You can see a slight increase if you kill unwanted processes/applications especially background ones.

It's my guess you are running the opencl vanitygen on your CPU and not GPU.
I have laptop with an Intel HD graphic, but never got the right drivers (ubuntu) working to run opencl on the graphic card.
But maybe the drivers for windows do work.
Could you try to run the cpu version (vanitygen64.exe) an check if the speed increases?
With an I5-CPU@2.6G you must be able to get >400kKey on the CPU.

vanitygen64 gives me 550Kkey/s.  oclvanitygen is much slower, that is why I know I am doing something wrong.
