i believe its the 6 and 8 pin.....
to put it one way, the first gfx card has a cable running from inside the box, and ending with a 6 and 8 pin labeled pci-e
the second one is a similar cable (ending with pci-e and 6 and 8 pins) but i have to plug it into the psu through some red pin sockets of 8 if that makes any sense
either way the fans are on, on the card
i know its a dumb question, but do you have the full 8pin 12v power cable connect to the motherboard? i did a quick search of your motherboard and it has a cover over 4 of the 4pins, you need to remove that little cover and install the 8pin cable.
if you mean the one in the corner with all the audio and usb ports, then yeah i removed that and im using the full 8, not sure why its covered in that picture (googled) dont think mine came with a cover.
finished updating the BIOS and all other mobo drivers, not having any luck yet looking through the settings
ill pick up again tommorrow evening, please leave more helpful suggestions ^^
