HD 6870 producing flickering

[huzi_a]

Hey guys, I have an Asus HD 6870DC and for some reason when I boot and I scroll in a web browser or move windows/minimise or restore them it flickers as if there is some horrible form of screen tear and lag. It does not occur in games though.

This occurred after I attempted to unlock the core voltages which for some reason are still not unlocked (SmartDoctor doesn't even know the card exists and afterburner even after editing the config doesn't allow v control). I've tried on different drivers. The only way to solve it is to change the resolution or refresh rate and change it back every time I boot. Anyone got any ideas?

Undo whatever you did? Sounds like you've set something to change at boot.

Uninstall and re-install amd drivers (What I would do).

I've already locked the voltage controls, removed the line from the afterburner config file and set it to stock speeds. I've already reinstalled drivers but nothing. I'll try the 13.10 drivers that just came out
