Please someone help me out

I got my self 2 Gtx 570 Cards i tried them running on Sli but Asus Control Panel will not detect any sli config could it be because they have a different Graphics core speed.

Card 1:NVIDIA GeForce GTX 570 Engine Clock 742 MHz
Card 2:point of View Gtx 570 Engine Clock 732 Mhz

That motherboard does not support sli. It has two PCIe x16 ports but with two cards installed it splits the lanes x16/x4 and NVIDIA requires at least 8 PCIe lanes per card for sli.

No, in the case of different clock speeds, both cards will run at the lower card's speed.

You said ACP will not detect an sli config, I run sli on an ASUS motherboard but do not use ACP to configure sli. Have you turned sli on in NVIDIA control panel? That is the only place you can do this. The feature is accessible through NVIDIA ControlPanel -> Set sli, Physx Configuration, then select "Maximize 3D performance" and hit "Apply"
