From
http://lifeboat.com/ex/press.releases.bitcoins.hundred.thousand.dollars :
"to give back to the bitcoin community, Lifeboat Foundation has created the first Windows version of oclvanitygen in the world that runs well on high-end AMD cards. (Our version runs nearly four times as fast as the old version!) You can download it for free at
http://lifeboat.com/oclvanitygen and can learn more about what we did on GitHub at
https://github.com/samr7/vanitygen/issues/19. oclvanitygen is used to create vanity bitcoin addresses such as our bitcoin address 1Lifeboatu7Y9YqKQRcXfjWYJdXog9CS7r that begins with 1Lifeboat."
Note that a high-end AMD card is defined as an AMD Radeon 7XXX GPU. If you have a slower card then you can just download oclvanitygen as described at
https://en.bitcoin.it/wiki/Vanitygen And if you need a Linux fix for high-end AMD cards, read
https://github.com/samr7/vanitygen/issues/19 to learn how to fix oclvanitygen.
Finally, oclvanitygen, no matter what the operating system, hates the latest AMD Catalyst drivers. So if, for example, you are running Catalyst 13.9, you would also want to use the AMD APP SDK Runtime from Catalyst 12.10. (So all your Catalyst drivers would be brand new except for the SDK Runtime.)
