I have some question about GTX 570 idle clock .

1. when both card idle , both clock will drop to 50 or 51 mHz ( not yet sli bridge )

2. when both card sli bridge , 1st card idle clock will be 50mHz but 2nd card wouldnt down clock n remain at the same clock ( 742mHz )

So my question is , when both card sli , 2nd card clock speed wouldnt down clock even idle ? coz now i have to use afterburner to set 2d / 3d profile , when idle it will change to 2d profile to force 2nd card to down clock to 405 mHz ( thats the minimum can set in afterburner )

whats the maximum save voltage for OC ? 1.1v is safe ?
