Hi everyone!
I have a horrible doubt: the PCI slot n. 1 of my Maximus IV extreme (P67 B3 revision) is already gone? (the mobo is new!!)
When I put my GTX580 in slot 1 the PC boot with AA code (all normal, right?) but the screen remain black and the vga_led is ON; with the GTX 580 in slot 2, 3 or 4 is all OK.
I have tried a SLI with 2 GTX580: if the 2 cards are in slot 2 & 4 the SLI is OK, but the card in slot 4 is very close to the bottom of the case and the card in slot 2 is extremely close to the other card and the temperature of both cards are very high, despite the extra fan.
A SLI with the cards in slot 1 & 2 give me the vga_led ON.
The number of the slot I have mentioned is referred only to the RED long PCI slot; I haven't count the small black one.
When the PC is booting I hear 4 BEEP: BEEP (pause) BEEP-BEEP-BEEP.
Have any suggestion, please?
UPDATE: with a 1394 PCI (short) card in slot 1: the PC boot OK, only 1 BEEP, and the Asus PC diagnostic give me "status OK" and "in use" for the PCI slot number one.
