    Hi all,

    I updated to the latest AMD Catalyst Drivers (12.8) and now my 6490M shows up at a Radeon HD 7400M in all my games and throughout the OS. I do want to mod the GPU a bit (overclocking/undervolting), and I was just wondering, is this normal behavior and okay to leave alone, or should I reinstall drivers?

    It is not normal but it is also the same chip. A 7400M is just a rename of the 6400M. Same process, same 5D architecture. I doubt it makes a difference.
