OC'ing a 4830

[Abyssalx]

I want to get some tips on OC'ing a 4830 to 4850 speed. I've seen it done, but I want some help one what speeds are okay for Sapphire's 4830 512mb and if I need any kind of extra cooling or anything. Thanks.

try to OC it 50Hz each time and see GPU temp with GPU-Z.0.3.1

and use Video Card Stability to make the GPU at load mode
