Yes it definitely adds to the random seed and definitely doesn't set it to some initial value. I've been searching for an easy way to mod it so it would search sequentially so I could get the 51st bit in that 32 BTC challenge thread.



By the way I launched a Vanity Generation Service at https://bt.irlbtc.com/view/1748422.0
Basically I offer free easy vanity generation and charge for harder to find vanities. So if you have a very slow CPU and want a basic vanity I can find it for you instead.

IF this post is considered spam, I apologize and will remove it.

So I recently spend three hours or so generating a new vanitygen address on my Notebook that run on AMD graphic processing unit. Before it reaches 50% it show something like


I Googled for this 'error' and it seem that this only happen when the GPU code do not match with the CPU code, hence not showing us the private key. The vanity address I was trying to generate was 1nTech.

I couldn't find a fix for this problem online - other than using my CPU to search. I followed an advice and generate short vanity address to see if this problem will occur or not, it does not occur and I manage to get the private key - for example 1111.

Anyone have any fix for this?

(I tried upgrading my AMD graphic processing unit but somehow my Windows have 'blinking' issue so I revert the upgrade.)

So, does anyone else have/had an issue where olcvanitygen never finds a matching key, and just continues searching regardless of how easy the request is?

Have just picked up a GTX 750 Ti brand new dirt cheep to replace an overheating AMD Radeon R9 200 HD 7900 Series card.  (one of two in the PC bought second hand) and can confirm am just scraping 17 MKeys/sec using the lifeboat oclvanitygen64.exe

Does anyone know how to get OCLVanitygen to work with 2 r9 290x cards?  I am using the lifeboat version.  Everytime I try to run the .bat file that I created, it just opens, list the specs of the cards and just closes.   I tried to install the old catalyst v. 12.7 software as some suggested earlier in the thread, but it doesn't work at all.  For reference, I have the new crimson software installed.

Any help would be really appreciated.

I used that line, but the screen just pops up and closes. 

This is the error I'm getting:

__constant bignum bn_zero;
                  ^
error: constant address space qualified variables are required to be initialized
2 errors generated.

error: Clang front-end compilation failed!
Frontend phase failed compilation.
Error: Compiling CL to IR

Could someone direct me to where exactly this lifeboat vanitygen is? Can I download it from github or am I missing something? Also could you link me to where it's explained what is does/if it's different/why it's better? Googling just keeps coming up with reddit post after reddit post but no real information for me... Sorry for the newb questions rofl.

I recently transfered 11 inputs from a vanity addy, and it made me realize the transaction gets quite big, which requires higher fees. Using vanity addresses instead of compressed addresses also adds more to the already large number of unconfirmed transactions.

I just found out Lifeboat supports compressed keys, which are 15% faster to find (source: README in this zip) than regular keys! But it's specialized for AMD, and available for Windows only. So I can't use it.
The last version of vanitygen is 4 years old now. It would be very nice to see an update that includes compressed keys. Unfortunately I don't have the skills to chance the source myself. It might be a relatively small change to add compressed keys.
