How to mine this with GPU? My friends want to mine, but i don't do mining so would be nice if someone posts a step by step how to do this.
I doubt anyone will do that, but I can get you started. Most people doing mining use ATI GPUs. For this script coin, you need to use cgminer version 3.7.2 or lower. After version 3.7.2 it no longer supports GPU mining. There is a fork of cgminer called sgminer which you can also use. All versions of sgminer support GPU mining. The hardest part is tweaking the command line parameters for the highest hash rate while still having stability. It takes experimentation to find the optimum values. If you google you can find much more detailed explanations for specific GPUs.
i have found a link that explains how to use the cgminer to mine dogecoin with gpu, its in good detail to get me started but does it matter if its another coin?? also.. since its my first time i think testing it while trying to mine asiacoin is pretty useless since i might be working more for the hash rate than letting it mine .. ofcourse if i find someone who has good settings for my gpu it would be much easier.
In this case it doesn't matter because dogecoin is also a scrypt coin. The settings will be the same but the settings vary with the GPU used. I personally had a hard time finding examples for my particular GPU but found a writeup on how to tweak the values written by the developer of cgminer, which was very helpful. The file name is "GPU-README" and you can find it along with the other source code files for cgminer at github
https://github.com/ckolivas/cgminerSome other files in the same folder: README and SCRYPT-README are also very helpful. You might have to do some tweaking because if the values are too far off it won't work at all. The README files explain all this. You can try using the values from an example and if it works that's good enough for now. Try to find an example that has the same GPU or very similar.
