ok so i think you will be my only hope fellow doge miners as i said before i have an a8-4500/7640g card im trying to mine dogecoin with. I'm currently trying to use cgminer and here is my error
http://i58.servimg.com/u/f58/17/22/50/91/dogee10.pngHelp please for the life of doge i have been trying to mine for 5 days now and have made good progress until this.
I had the exact same problem when I put my GPU in an old Win XP computer.
What I found was that I *had to* get the old AMD Catalyst 12.1 because that is the last one which contains OpenCL.
After I downloaded that one, I *de-installed* the Windows default driver for the GPU and then installed Catalyst 12.1
(this computer had a display processor on the motherboard that the monitor was plugged into, so I could easily remove the driver from the GPU)
but you may need to install Catalyst 12.1 first, then make sure to change the driver for the GPU (so it does not use the default windows one)
Then find cgminer 3.7.2 (later revisions do not support Doge mining)
Then you can start and optimize the setting for the miner.
Let me know if you need links for the stuff.
Success!
