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

[coinpr0n]

Kudos. Thank you for this piece of software. It's been really useful.

i did all the commands there, im not sure which sentence of all the 200 lines that gaves me back, its the correct that says how much cpu my mother can see. (i send you a pm)

as far as i can see, my pc only detects one vga

env LD_LIBRARY_PATH=./sdklib ./oclvanitygen -D 1 -i 1Nasty
Difficulty: 15956296
Invalid device specifier '1'
Could not open device '1', ignoring
Available OpenCL platforms:
0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing
  0: [Advanced Micro Devices, Inc.] Tahiti
  1: [AuthenticAMD] AMD Athlon(tm) II X2 270 Processor

the -D 0:0 it works. but the others dont... :/

i installed a program called lshw-gtk  that shows all the hardware in the pc, and i can only see 1 vga i think.

first, nothing to do with "VGA".
second, use the appropriate option! its -D not -d.
example:

Code:

./oclvanitygen -D 0:0 -D 0:1 -D 0:2 -D 0:3 -D 0:4 -D 0:5 -D 0:6 -D 0:7

next time check the --help

thanks this is really nifty for business names - to put a name to an addy

Just keep in mind that you should never use that as anything more than exactly what it is, a vanity.  Say you generated a bunch of vanity addresses '1Actua1', and advertised that as trusted addresses for customers - then I could easily generate my own '1Actua1' addresses and try to con your customers into sending funds to me.

 That being said, how can we now trust that you are in fact The Real Steve?

You can't   Though if I managed to create a 1TheRea1Steve, that'd be pretty good

quick question, i installed ubuntu, installed drivers, and folowed the guide i posted before.

Why ubuntu cant see i have 2 or 4 vga? Is there any driver im missing?
Im not thinking in oclvanity, im wondering why ubuntu cant detect i have more than 1 vga plugged in... its odd :/

Hi,
I have a question to oclvanitygen users.
I successfully compiled the software under Debian linux. I have old mining rig with 4 GPU.
Everything seems to work but the load of the cards is quite low: 70-90% and not stable.  Nothing that I'm used to when I recall old mining times with stable 99% load in cgminer.
How to increase the load to 99% ? It lowers performance a lot with ~80%.

Second question. I'm unsure how to read the results.
vanitygen provides simple and clear output:

Example:

Code:

./vanitygen 1tst
Difficulty: 4553521
Pattern: 1tst                                                                  
Address: 1tstajg1J32HDSVnFDpCoQ8rTCxmNRYvy
Privkey: 5KUruEhXzvmmCJuKhEUtzadNe51DgQzHuGA7EFeBM5mcwRDR2C1

oclvanitygen provides something different.

Example:

Code:

./oclvanitygen -D 0:0 -D 0:1 -D 0:2 -D 0:3 1tst
Difficulty: 4553521
Match idx: 0
CPU hash: a159f76402d9bab648b806082fbc347818825e98
GPU hash: 09cfb112e8f825a6a2ea5b6f83b96e33ac70c459
Found delta: 5955016 Start delta: 1

How to convert it to normal BTC address and private key?

I also noticed when I turn on single GPU workload rises to 97-98%.

1) are you using libssl 1+?
2) newer gpus have a problem that results in incorrect hashes (the message you get from oclvanitygen). search this thread for a post of nasty with a patch for it.

[oktar]

1)

Code:

# dpkg -s libssl-dev | grep Version
Version: 1.0.1e-2+deb7u14

2)
My GPUs are not the newest ones, I have 4x MSI Twinfrozr 7950.
I'll try to find a patch. Thanks.

For me I have a Nvidia 9500 Gt (2.5G) its so slow for this tool , I run it sometime 20 minutes for a 3 key pattern and
the speed is 216 key/s . Is my graphic card the only slow here ? or 216 is good ?

Is there a way check balance of vanity addresses automated?

You'll have to be more specific in what you're trying to achieve.  'vanity' addresses are just like regular addresses.

thats a ancient card. be happy that it even works!

I tried to run separate instances of oclvanitygen inside 4 screens in console.
It's weird, first card was hashing at 21-23Mkey/s while the other three at 11-13Mkeys/s each.
When I run single instance I have combined computing power of ~51Mkeys/s. With 4 seperate instances when adding the values it is ~54-62Mkeys/s.
The load was ~90% on each card so better than with one oclvanitygen instance but still not ideal.

Anyone has been using this on multi gpu machine? Is that normal? Why I can't have stable 99% load on every card ?

Edit: I check load % with aticonfig Overdrive if that matters.

I know.I mean check balances automated.

seems you are trying to bruteforce addresses and check if some BTC are available with a given privkey.
simply said -> forget it, wont happen!
if you really want to be stupid and ignore the math behind it, you can try "Deep Space Vagabond"...

I already tested that I hated my self because i was so stupic ;
I generated 80 k addresses and save them with python then create a tool with php to test them all in the blockchain
it take 4 or 5 hours and all the addresses were 0 funds of course 

[organofcorti]

Which reminds me - I know this has been asked before but I can't find the reference.

Does anyone know of a fast address generator? I can regex a batch myself (to look for vanity addresses), but the address generators I've written are far too slow. As a plain address generator, even vanitygen is slow. Any ideas?

Gotta love Vanity address's
