Changing Flip queue size on HD7770

Hi guys, I have a radeon hd7770 gpu and im trying to change the flip queue/ pre-render frames.  I'm having a hell of a time. To start i'm using the latest Catalyst CC drivers. Search online I found radeonpro, so i download it and it works for a bit but then causes serious problems. I've gotten blue screened twice, then this last time my computer froze and wouldn't boot up (got it to boot eventually after i let it sit for the night). I uninstalled it and tried Ati try tools but i think it's too old for my card. The only other option i can find is registry edits for catalyst, which i would be willing to try but i have virtually no experience with that stuff.


Any ideas? Anyone have this problem too?
