Tried the Cmos battery thing which did not work. I am betting motherboard not getting enough voltage to post with the 580 in master slot....any ideas how to fix this?

Also I noticed when i plug the 580 into master slot 8 beeps no POST. 

But when i put the 560 into the master slot works great....maybe a motherboard voltage tweak needed? If so how do I do that?

Thanks i hope this works is it also possible not getting enough voltage? If so how do I increase voltage?

Ok thanks which is the master slot left or right?

Ok so I am trying to upgrade one of my gtx 560m to a gtx 580m now I ordered one fresh factory sealed gtx 580m. When i put it in master pci-e it gove me 8 beeps and no display....however in secondary slot works ok.. ..i do have an unlocked BIOS A05.... can this be the problem? Please hurry with response I am getting a replacement  one in a few days....

Thanks
