I was trying some new settings and it bewildered me that something as simple as a 10-30MHz OC on the FSB causes issues with atikmdag when ever I use a 3D application. I think even Vista Aero crashes it as well. But Something as monstrous as 50-100MHz (300MHz FSB is pretty insane lol) is perfectly fine. Whats going on with this atikmdiag and is there any way to get around it. I'd rather have a bit of both worlds in the overclocking business, FSB + Multi.
