The official clock boundaries are set in the bios. I don't know much about Linux, on the other hand, I know from experience it's not too complicated to modify your bios with RBE (which is a windows tool if I recall. Yet once it's done, you're all good).

the problem on this one is that you only can actually manage only one GPU. in my case with a 5970 card that has 2 GPU's, i only can do the settings on the first gpu DEVICE=0.
