Available OpenCL platforms:
0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing

  1: [GenuineIntel] Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz

CPU 1 - 1,5 MKey's
GPU 29 - 30 MKey's

So, i will use the GPU, but the output is ....

Might want to run them a little longer than 20 seconds, but I'd also double-check what (ocl)vanitygen is putting on the screen.  It could be that your GPU is generating addresses that are invalid when checked by the CPU, and thus rejected and not written out to the output file.  Edit: Oh, and just in case it's not clear, the keys/s only means the number of keys it can check per second - you'll find far fewer vanity addresses per second than that

 You are getting rather confused I think. You have switched the devices on us??
-d 1 should not be the GPU

Earlier you told us this:


 Which indicates that the device 0:0 is the Tahiti (or the GPU) and the device 0:1 is the i7-4770

 So the option -d 0 should use the GPU but it doesn't work properly because you have the wrong driver version for AMD which will not work with oclvanitygen.  It is evident by the output you have shown us.
 Using the option -d 1 will use the CPU but it doesn't make sense to use oclvanitygen on a CPU when in fact vanitygen would probably be faster.

You have to completely uninstall the AMD drivers and reinstall with an older version.  I will try to find this information - I believe it was already posted here with a batch file to assist in removal.

I have two AMD Radeon R9 200 HD 7900 Series Graphics cards in a Win 7 box. 

Reading through the earlier posts of this thread, I went off and updated the drivers to the latest Ver 15xxx I would get ~ 25 - 27 MKey/s per card but then would get stalked night and day by Delta and Co.

Some more reading and using the -S safe mode, the speed is throttled back to ~ 9 or 10 MKeys/s per card

So, more reading and I used the uninstall program mentioned here and uninstalled the AMD drivers, then installed the ver 12.10 drivers as suggested.

I would again get ~ 25MKeys/s per card, but then Delta... she came knocking again.

So I again used -S safe-mode and got ~ 6Mkeys/s per card.

So I rolled back to the previous install (15xxx) and am back to either ~25Mkeys/s with Delta lurking behind every rose bush, or -S safe mode ~10Mkeys/s

However... after about 48 - 60 hours the program freezes, so I have to Control-C to exit and start afresh.

Any suggestions would be appreciated.

I also have a 2 - 3 yo laptop with an nVidia graphics card and get ~2 Mkeys/s (in all of these examples using oclvanitygen ) without having done anything to the drivers and haven't had Delta come a knocking, so am thinking of taking one of the AMD cards out of the Win 7 box, dropping a GTX 780 Ti card in to search for vanity wallets and the remaining AMD I can use for incidental script mining or Vanity mining for other Alt coin wallets from time to time.

Just one final question:

I have a work.txt with about 200 wallet prefixes to search for; I'm a little unclear, does the program search for all work examples, or focuses on one particularly easy one?  Why I ask when I've had to restart due to the program freezing (or last night's suburb wide black out for 20mins) the same results occur in the same order and at about the same time duration.

Thanks for looking.

 You are partially correct.  The program searches for all prefixes in your file and shows the probability of matching not the easiest but any prefix (it's basically showing the sum of all of the individual probabilities).  Prefixes with a higher probability will likely be matched first but not necessarily.  

Looking for some advice if anyone has an answer.

I can run the miner (oclvanityminer64.exe) on my GTX860M without any issues, but when I try to use the miner (oclvanitygen.exe) to mine a address locally I get the following error.

Anyone know how to get around this? Possible that its because its not x64?

If that is the case, does anyone know if there is a build for x64?

Thanks for that tip. I deleted the two that existed and it started to work. Much easier than what I was expecting. Went from the 900 Kkeys to the 15-17 Mkeys I was getting for the pool.

Appreciate it greatly.

Hi,you can use that "feature" in whatever going on your mind, the main idea here is that you can give a "face" to the non good looking bitcoin addresses and let them look a little bit more humane readable,it can be good in terms of UX/UI or if you want to have a "unique" address that will help people know who you are/what is your bitcoin "identity" ,you can check that service that i am trying to develop and that include some "vanity address" feature's : https://www.riders.io/

I have also question for the people here,i tried to generate an address with 6 patterns (case sensitive) with my 9600GT card,it took almost 2 weeks lol,how much GPU power i need in order to lower that time for something like 4-5 hours? how much graphics cards?
Tnx!
