After I ran the oclvanitygen.exe with a test address it came up this:
Available OpenCL platforms:
0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing
0: [Advanced Micro Devices, Inc.] Hawaii
1: [Advanced Micro Devices, Inc.] Hawaii
3: [Advanced Micro Devices, Inc.] Hawaii
4: [GenuineIntel] Intel Core i5-4570 CPU @ 3.20GHz
But I don't know how to add the AMD gpu so that it will start working with it. What should I write in the command line for it to do it with the gpu?
I'm not too sure to be honest. If anyone else knows, feel free to chime in.
You specify the device, using -d (device number).
For example, you should use oclvanitygen.exe -d 0 1WTFisThis. If it doesn't worked with all cards specified at the same time, run multiple instances with the different devices.
