Split-key vanity generation is much slower
I've read this before, but it's not what I experience. I just tested it, for both vanitygen and oclvanitygen, and I see now difference in speed (key/s).

Quote
and doesn't enable you to search for multiple addresses at once.
It does, but they'll all work with the same public key. I use it to search for either one of several possible prefixes. For example: 1NAME 1Name 1name.
It's not as fun as just taking a list with 8000 long words as input though.

I can't speak for your experience, only the facts.  Split key generation is slower because of the added process.  Your example of using the same public key for multiple split keys also restricts your search, meaning you cannot perform any other vanity searches not using that specific public key alongside it.  That makes split key generation slow and expensive to the point where I don't believe it makes sense for individuals to utilize it, or pooled miners to attempt profits mining vanity addresses.  It's a lose lose situation for everyone involved.


I have been looking through the pages and pages of this post again.
I can't seem to find a list that I thought I remembered, is there a complete one that lists all the current cards and their speeds?
Or to make my life easier, if cost was no object what is the fastest card for generation?

Looking for 1 card not a rig.

Thanks,
Dave

The fastest and most efficient card for use with vanitygen is hands down the R9 Nano.  Unless you can get a 480 to work, which I have yet to see outside of the claim on the wiki.

  Somebody created a Vanitygen page on the Bitcoin Wiki which contains a table with information that will help answer your question.   Most of the footnotes link back to threads (or posts I guess) that can be found here Wink

The fastest and most efficient card for use with vanitygen is hands down the R9 Nano.  Unless you can get a 480 to work, which I have yet to see outside of the claim on the wiki.
What kind of speed does it do?
I searched the thread and see you commenting on it's efficiency but I am looking at speed.
Thanks,

I run mine underclocked, but still get 48Mkey/s.  I'm sure it is possible to get a slightly faster card, if you don't mind spending double on electricity and enjoy heat.

Hello, i'm interested in using my r9 280x to generate keys, would you have any idea how many keys I can generate? Thanks!


Edit: I was able to run it, currently getting 29mkey/s

Hello, I was generating with my gpu but i'm not sure where the privatekey and publickey are stored, all i get is this:

What you just posted shows that you were at about 31.7% chance of finding a private key at that point. When it stops you'll have your public and private keys. It looks like you were doing something fairly simple so I'm assuming it should be done by now, right?

my 480s work.. and my 470s.. i get around 35mk/s with them.. 140-150mk/s for all 4.. 2 470s and 2 480s.


you need to edit a file in the folder. it was posted a couple pages back..
https://bitcointalk.org/index.php?topic=25804.msg16917413#msg16917413


edit, actually if you dont use the -S option its double this speed.. and my tests show the key works?

I had to enable -S safe mode to make it display privatekeys, but now it's only half the speed, 14mkey/s , would you know if it's possible to get full speed without -S mode and still display privatekeys? It only shows me the CPU and GPU hash like my earlier post. Thanks!

Is this the GPU you would suggest?

http://m.ebay.ca/itm/AMD-Radeon-R9-Nano-VisionTek-4GB-/322347235890?nav=SEARCH

I see lots of different GPUs with R9 Nano in the title so can't really figure out what I'm looking for.

The fastest and most efficient card for use with vanitygen is hands down the R9 Nano.  Unless you can get a 480 to work, which I have yet to see outside of the claim on the wiki.

Is this the GPU you would suggest?

http://m.ebay.ca/itm/AMD-Radeon-R9-Nano-VisionTek-4GB-/322347235890?nav=SEARCH

I see lots of different GPUs with R9 Nano in the title so can't really figure out what I'm looking for.

Some people have gotten rx480's to work, so that might be the best option these days.  The new AMD Vega line is also coming out soon, which could be a great vanity miner if it's affordable...

I don't think oclvanitygen will work on Intel HD Graphics. That leaves CPU-only, which is a lot slower, but should work. Try vanitygen.exe instead of "ocl".

So what I linked to, that's a rx480? When I just search R9 Nano I get so many options with diamond this sapphire this... I don't understand any of it.

Any experience with external GPUs (eGPUs?)?

Brainwallet.org is no longer functional because Its not secure , see this reddit post : https://www.reddit.com/r/Bitcoin/comments/3g7bpa/brainwallet_shut_down_permanently_due_to/
If you insist on using it then you should check github , you might find some forks from the official repository and run it locally from your PC.

Anyone know what I need to modify to make the search start from a particular address and go up sequentially?

Basically I got a few GPUs that can no longer mine ETH and ZEC and for fun, I want to solve the 51th bit in the "32btc contest thread" located here
https://bitcointalk.org/index.php?topic=1306983.0;all

I just need the search to start at 1,125,899,906,842,620  and end at 2,251,799,813,685,250.

 Vanitygen isn't going to help you with that.  What you need to do is convert those to hexidecimal, generate the corresponding wallet import format private key and find the address.  Vanitygen randomly searches out addresses and compares them with your search parameters.

Code:
Take your decimal number.
I like this one: 1,125,899,906,842,623 because it converts to this

11111111111111111111111111111111111111111111111111 binary number

but you need to convert it to this

3FFFFFFFFFFFF hexadecimal number

then pad it with zeros to make it 64 characters

0000000000000000000000000000000000000000000000000003FFFFFFFFFFFF

now add 80 to the beginning (to make it a Bitcoin private key)


800000000000000000000000000000000000000000000000000003FFFFFFFFFFFF (keep this one in mind for later)

Code:
hash it once (SHA256)

08260BC6AE17D00E40464A8EE0DA4C9FDAF1BEFC14C528CFC169798D868860DD

hash that result  (SHA256)

53FA3A525E44DEF51F9A0B6E910E6DCA51AB0A99E1756BB97BE32E01308390A0

Now take the first 4 bytes (this is the checksum) and add it to the end of the red number

800000000000000000000000000000000000000000000000000003FFFFFFFFFFFF53FA3A52

convert that to Base58

5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nFAaVmEdoLi3nb9s
There you have the uncompressed wallet import format private key for your original decimal private key which gives you the public address of:

1JnSYv9ZQ4kLRANt4FgbGVYBPXCrpfek6P

Which is empty. (one down, many to go!)

 Seems like you need a specialized computer program to run through the possibilities for you but not Vanitygen.
