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

[salfter]

Code:

./oclvanitygen -D 0:0 -S -X 48 L

This should find a Litecoin key.  Instead, it runs forever. Is this a known limitation of oclvanitygen?

Use

Code:

./oclvanitygen -D 0:0 -S -X48 -i Light

You cannot have a space after the -X flag.

Code:

./oclvanitygen -D 0:0 -S -X48 L

Didn't make any difference...still grinds away forever without finding any keys.

And it just goes on forever and ever. but if i do it with the cpu version it work for perfect in no time. i read through form and have not noticed any thing posted about this.

I've come across this too with a full uninstall of newer drivers (removal tool) and downgrading to 12.8.

The only solution I can use to avoid the loop above is to run in safemode with the -S flag.

This does run a lot slower than normal.... however it is still a lot faster than my CPU.

I ran into this issue myself - was mining for a prefix 1piit79 on a 7970 and didn't realize it was a bug until I tried 3 times (and wasted quite a lot of GPU time - 50% tok ~7h )

Funnily enough it worked just fine when I ran it on 5870 (and it was surprisingly just a bit slower than the 7970).

I think your device flag is wrong. Also, I'm assuming you don't have more than one GPU because of your flag structure. Try:

Code:

./oclvanitygen -d 0 -S -X48 L(prefix)

The capital D might be why it doesn't identify your GPU.

i found a solution for the vanity.thruhere.net site

how do i submit my solved work?

[vlees]

I never got oclvanitygen to work on my GPU (only CPU which gets 750kkeys/s) so I read here that I should downgrade to AMD Catalyst 12.8.
So I did that, but still oclvanitygen does not work on my GPU:

Code:

Compiling kernel, can take minutes...LLVM ERROR: Cannot select: 0x549e808: i8 = ...

Anyone knows how to fix this?

I was getting a similar error from my 7750 when I was running it with 13.1.  It works fine with 12.10, though.  I'd give that version a shot.

Thanks, I'll try. I just painfully downgraded to 12.8 recently because this thread said so...

It works fine for finding Bitcoin keys when I invoke it like this:

Code:

./oclvanitygen -D 0:0 -S 1

I have only one GPU, but note that the CPU is available as an OpenCL device as well (-D 0:1).  Not that you'd use oclvanitygen with your CPU as vanitygen is faster, but you could.

...and for me, it just runs forever. Just tried it again with a 7750, then with a 6870 and even a Core 2 Duo E8400. What card and ATI driver version are you using? Leaving out the device-selection option causes it to exit with a list of available devices.

no ATI, a GTX580

does it spit out "Difficulty: *" or not?

It does.

I think I've figured out what's happening: oclvanitygen will only find keys wirh vanity addresses for non-Bitcoin address types.  These commands work:

Code:

./oclvanitygen -D 0:0 -S 1
./oclvanitygen -D 0:0 -S -X 48 Lfoo

This doesn't:

Code:

./oclvanitygen -D 0:0 -S -X 48 L

The degenerate case where you just want an address appears to only work for Bitcoin.

try with an older ATI SDK?

The degenerate case where you just want an address appears to only work for Bitcoin.

Not just the degenerate case, but certain prefixes.  I can't generate Li (hashes a long time when it should easily find it), but I can do LiG easily.  For some reason Lig says the prefix is not possible, but it should be, right? Edit: deepceleron explained this.

The problem exists in revision 75246451d38140261f5318c258e53e4db7875607 when the -X flag was added to oclvanitygen, so maybe it was never really working.

See:

(lightcoin) Valid addresses are in the range: LKDxGDJ-LiZZFKc7

[pvtbrutus]

Just posting this for anyone who is interested.

I get 26 Mkey/s with a GTX 680. Was quite easy to get running, only launched CMD and "oclvanitygen.exe 1Brutus".

Found my "1Brutus" address in 6min .

Aha, you're right, thanks.  If anyone's curious, I verified these on brainwallet.org with hex strings 30000000000000000000000000000000000000000000000000 and 30ffffffffffffffffffffffffffffffffffffffffffffffff which are the lower and upper bounds of a litecoin pubkeyhash (1 network byte = 0x30, 20 bytes of hash, 4 bytes of checksum).
