Abnormal Graphics consist of bits of squares in max overdrive on 5870

I have many bits of un-rendered squares all around the screen if you ever use overdrive, which make the graphics abnormal.

It, or you, is setting the clockspeeds too high.
From what I have seen the HD5870 is a poor overclocker so you need to use the manual sliders to set the clockspeeds and only increase them a little at at a time, testing (use Furmark) after each change.

Doc: "Stop doing that."

ROFL - turn down, turn off Overdrive.

refer to ATI overdrive , not other third party overclockers.

Is auto-tune fine enough? I got 890mhz clock speed (850-900) and 1290mhz memory speed (1200-1300).

Any stable suggestion?

Start to back them down a bit and test. Auto-Tune can overdo it sometimes.
