Create vanity bitcoin addresses four times as fast

[brox]

The new payments API is going to make addresses of all sorts obsolete.

Can you please clarify?

I was hoping it could help my Nvidia, but seems unaffected, same speed, can you do something for us nvidia users or it's impossible?

Our fix only affects high-end AMD cards. On the positive side, NVIDIA cards have no problems at all running with oclvanitygen. For example, we are getting 28 Mkey/s with our EVGA GeForce GTX770 2GB running on an ancient 7 year old HP xw4400 workstation and that is the machine that generated our 1Lifeboatu7Y9YqKQRcXfjWYJdXog9CS7r address. We are currently getting about 22 Mkey/s from our Sapphire Radeon HD 7950 3GB. Before our fix to oclvanitygen, we were only getting 6 Mkey/s out of it which was painful.

I'm running it on CPU, and getting 80 Kkeys. so.... hehehehe..

@lifeboat, does yours make compressed keys? the private keys that begin with letter L or letter K instead of number 5?

I don't know much about compressed keys, but I checked and there seems to be a version of oclvanitygen at https://github.com/scintill/vanitygen/tree/compressed_opencl that handles compressed keys. I could compile a Windows version of it if there was much demand.

This is really cool.

Well, it would seem that I'm the only demand. But I don't have a high end GPU now anyway, so it won't do much good until I get one. But a Windows version would be appreciated.

Compressed keys are better for you because you use up less bytes for every transaction. You put less data in the blockchain. And you end up paying less transaction fees.

I'd love one that made compressed keys as well.

Though I can't even get this one to work, I'm using an Windows 7 + Radeon HD 7800 + Catalyst 13.9 + "AMD APP SDK v2.8" which is supposed to be the SDK from 12.10. It just does the usual thing where it seems to find a match but doesn't print anything. Did I do anything obviously wrong? The catalyst 12.10 drivers won't even run on this card, but the first post said you could use the APP SDK from 12.10, which I thought I did.
Have other people gotten this to work on a modern AMD card? Am I using the wrong version of something somewhere?

http://lifeboat.com/oclvanitygen has now been updated.

To create compressed keys use the "-F compressed" option as in:

oclvanitygen -F compressed -d 0 1Life or
vanitygen -F compressed 1Life

(So we also added a vanitygen program for those of you with no GPUs.)

[Dabs]

Just because: can you kindly do a md5 sum, sha1 sum or sha256 sum (or all 3) of the zip and the individual files. Then GPG sign the whole list?

and oh, I just tried to run it. It's not a win32 app? it's 64 bit? heheheh.. Do I need to upgrade my OS to 64 bit? (I have 2 old laptops running Win XP 32 bit.) I do have Win 7 64 bit, but I never installed it as I don't have more than 4 gig of ram.

[ratty]

Thank you so much! Works great on my old Radeon 4800. Its equally as broken on my 7800 as the original oclvanitygen with SDK 12.10. At least I can make compressed addresses on my older computer, so progress has been made!

We now have compressed keys support at http://lifeboat.com/oclvanitygen

Sounds like you have a challenge ahead of you. (AMD driver issues can be fun!)

It is our impression that all Radeon HD 7XXX cards should behave the same for drivers and programs. We happened to have a Radeon HD 7850 lying around from earlier tests so we just installed it and it does work fine with our version of oclvanitygen.

So the first question is: Are you trying a long enough bitcoin address? It should be at least four characters long to get stable results. So 1Life should be good for example.

The next question is: Does using the option -S enable you to get results?

The next question is: How could the catalyst 12.10 drivers not even run on your card? What error do you get? Note that it is difficult to downgrade your AMD drivers. After uninstalling your current drivers, we recommend that you run the following batch file before then trying to install the old catalyst drivers:

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

I would recommend first trying to get the old drivers to work on your machine before you go for the more complicated option of running the old APP SDK plus the new drivers.

One more question, exactly which graphics card are you using?  Is it a Radeon HD 7800M?

[lifeboat]

We've been testing it on 64 bit systems although dumpbin /headers claims that both programs that we are providing are 32 bit programs. Assuming it is a 64 bit program, do note that would enable the non GPU version (vanitygen) to run 50% faster as vanitygen does a lot of large integer arithmetic. What error are you getting?

I looked it up from the invoice from when I purchased it a year ago, it's a 7850. Here's the info page from where I purchased it:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814121623

I tried generating 1Life and it finds it over and over but never prints the key.
Another clue I have that something is broken, is the kernel it makes is 700K. On my older card it makes one that is 3.8MB. If I use -S on my 7850 I get a 400K kernel with the same broken results.
Now that you're telling me the Catalyst 12 drivers are supposed to work on a 7800 series, I will give that another try, this time with more confidence! I'll try that batch file too.
Thanks for the help!

vanitygen.exe is not a valid Win32 application.

oclvanitygen.exe is not a valid Win32 application.

I'm on Win XP SP3 32 bit.

Let me know how the Catalyst 12 drivers work out. As I said we were able to test it on a 7850, same as yours, with no problem.

[ratty]

The downgrade to Catalyst 12 worked, maybe I needed to do that batch file, but it works now.
I tried upgrading to 13.9 without clicking on upgrading the APP SDK, but that still broke it. Oh well, at least I can make it work now!
