Interesting...

Could you run GPU-Z
Select the sensors tab and monitor the "gpu core clock" and "gpu memory clock" do these values jump to another value when you experience this tearing?

The GPU Core Clocks jump as expected from 400MHz(idle) to 1000MHz(load). The memory Clock doesn't change.

I found something interesting. It seems that when the fps drop below 60(and my monitors are running at 60hz), the tearing starts on all 3 monitors, and when Im pushing 60 it only happens on the left one with miniDP->DVI

That has something to do with vertical synchronizing (v-sync). V-sync tries to match your frames per second with your monitor's refresh rate (hz). However, due to the different signal coming from your miniDP, the card can somehow not handle that.

I'm still waiting on the answer from the sapphire guys, as soon as they say something I'll post it here.

Are you able to confirm that the screen tears when the gpu core and or memory speeds change?

When the core clock jumps it does tear, but that is normal. But in games the core clock always maintains maximum value and it still tears, wouldn't mind the tearing in windows because of the clock changes.

Tearing in Windows has to do with the memory changing frequency changing not the core.

Yeah, you are right, sorry for the mistake.

Thats not real Tearing isn't it ?
I get the same when i start a Youtube Video and clock goes from 400 up to 925 (Standard clock is 1000mhz! 9125 is for hardware acceleratet stuff like Flash videos)
a flickering /tearing similar effect only on one monitor. But it's not happen every time, just sporadic.
Btw -.- Youtube Video paused gpu clock goes down to 501mhz... i don't get it... seems like i have way to many GPU states -.- 300mhz, 400mhz, 501mhz, 925mhz, 1000mhz(standard)!
VRAM is differenty.. too. 150mhz for idle 1375mhz for Flash based hardware acceleration and 1425 Standrad clock.

Someone has said to me in another forum that this active adapter fixes tearing:

Accell B087B-006B UltraAV Mini DisplayPort to DVI-D Single-Link Active Adapter ATI Certified

He says the problem is HDMI->DVI and that two monitors with miniDP to DVI active adapter will fix the problem.

Anyone can confirm it? The price is kind of steep and I wouldn't want to throw away my money. Its almost 50 euros here in Spain.
