Nope, no place in the bios to change anything. I have even updated the bios and have read the motherboard's manual over and over again. They don't give much info. I have tried various setting as well in the bios to no avail.
The card is in the primary slot, as indicated on the motherboard. I haven't tried it in the secondary slot yet, that sounds like a plan.
Not familiar with a shadow card. Maybe I should live like a vagrant for a month or two, save up some money and buy a second card.
My pc is working fine with excellent graphics, I am just curios over the x8 I saw...
