during this time, i tried the both ways (the one in the rage3d and the one in the techpc). the techpc method didnt work for me. some driver problems. this was confirmed when i used the audigy2 software in the techpc with the drivers in the rage3d one.
so i reckon is: use the software in techpc link with the instructions in the rage3d post. because, the software in the rage3d link is chinese, so u wont get any probs if u use the software in the techpc post.
