Hi!
My system is i3770k with asrock Z77-extreme6, 16gb ram...
I've recently bought a hd7970 (sapphire vapor-x).... if I leave the first pci-e set as "auto" in the bios-entry for the "generation" of the slot (1.0, 2.0, 3.0) the system will set it to 2.0 ... no problem ... and everything works ok ... (as for my old hd6970)
If I try to force it to GEN3, it only works for the first time when I turn on the PC (and the video card is set correctly to 3.0) ... but if I shut down the PC, at the second firing, however, the video card is no longer detected (I have to connect the integrated Intel and reset to "auto" in the bios) ...
Ideas!?
(excuse my BAAAD english!)
