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

why does oclvanityminer fail on windows?

Code:

C:\>oclvanityminer64.exe -u https://vanitypool.appspot.com/ -a myaddress -v

I just tried downgrading to 12.8 but that immediately broke everything. cgminer, vanitygen both crashed immediately upon startup.
I first uninstalled my cards and deleted the driver via device manager, then used the ATI installer to clean up the rest. Then I rebooted and installed 12.8. Any ideas?

Look around on the AMD site for the AMD driver removal utility. Use that yo remove drivers completely, reboot, and reinstall drivers. The driver uninstall process doesn't work correctly. You need the removal utility.

Thanks so much jay! Works like a charm

I'm assuming you found that tool. No problem though. I always had so many issues with drivers until I found that tool. The very next install and it worked great!

I could only find the windows 7 version. I got really wrapped around the axle trying to revert to prior driver. Wish someone would update the GPU version of the Vanity utility. 

Do you know if the windows 7 works for windows 8 or if there is another version out there somewhere?

The win7 version should work for the win8 version because I don't think the file structure isnt any different. Try it and report back!

hello,

I was playing around with the vanitygen seed option from a file.

It surprises me that vanitygen gives me every time different results while having the same seed.

Can someone explain me briefly why that is?

thanks

[daemondazz]

Without looking at the code, because the seed is only part of the entropy?

I'm getting 1.10 Mkey/s on my computer, let's say I want to run this operation on an FPGA, would it be similar to a bitcoin miner?  How do I increase the Mkey/s rate on my computer?

Thanks

So if you wanted an oddball beginning would you convert the first number/letter to hex then it would be like

-X4a for J?

[Boelens]

I'm getting 61 keys/s, will my 7 letter prefix take long with such an amount of keys/second?

J is 43. This page explains it: https://en.bitcoin.it/wiki/List_of_address_prefixes

thats wrong since you have to supply it as hex value, not as dec

Yes, it could take years if you are only getting 61 keys per second. The average time is shown in the output.

Ah. I guess I'll go to a paid service then =P.

You should not write about something you know nothing about. It only demonstrates your ignorance. The value is not hex.

is there a version i can download that gives me compressed keys?

i'm on win xp

[grabber]

Great stuff, thanks for sharing

[scintill]

If anyone is interested in generating compressed vanity addresses, see this Pull Request.  salfter did the CPU side, and I commented with a link to my fork that includes his work and adds OpenCL support for the GPU side.  Please be careful and verify that addresses you generate using my changes are correct before sending money to them.

Using compressed addresses saves a few bytes in the blockchain every time you spend from them.  Addresses made in the latest versions of bitcoin-qt are compressed by default, but not all clients support them (so you might want to make sure before spending hours generating one.)  A bonus is that generating compressed vanity addresses is a bit faster since there is less data to hash each time you try one.

[Dabs]

Mr. salfter and Mr. scintill, if you upload your windows binary, and sign it (or SHA256sum it), I will download it. I'll also be sure to scan it (or run it sandboxed.)
