I haven't used RBE for years, last time I did was when I still had my 4850. Since then I forgot pretty much everything I knew, and rest changed with new technology. I did read the guide and still am fairly confused. Hoping someone can shed some light onto this. 1) How comes there are 6 clocks in the bios I saved from my card, and about 10 in other bios for the same type I downloaded? Or rather, why can't I add new ones? Say I want the card (5850 in my case) boot with the default 725/1000 clock, but the actual 3D settings would be 800/1200. How do I do that when I can't (unless I missed something) add another clock and there doesn't seem to be a way to change how the modes are connected either? 2) Do the upper clock limits only apply to CCC Overdrive function? I understand how the signatures work, but maybe if I just set the clocks in bios I don't need to bother. 3) Does the "memory clocks should all be the same" rule still apply? I remember it would do funky stuff on my 4850, but seeing the current untouched bios has 1000/900/300 maybe it's no longer the case?
