Hi everyone, I'm having some trouble with my SLI setup of 2 GTX680's (asus DC2T edition) on my Asrock Z77 Extreme9 motherboard. Under load GPU-Z reports 1 card correctly at PCI-E 3.0 x16 @ x16 3.0. However my second card is reported as PCI-E 3.0 x16 @ x2 3.0. Screenshots: card1: card2: I have check my os's powersettings, driver settings etc etc, all seems fine. The cards are installed in slots PCIE1 and PCIE5 as described in the mobo manual. I don't know which one is reporting the lower values of these 2 slots. I've already tried swapping the cards between the lanes, swapping SLI bridges, ..., all to no avail. Currently I'm at a loss on why the second card is stuck at x2. Is it possible that the PLX chip is faulty? The only other relevant info may be is that since recently, I have to overvolt the cards a bit higher than i used to do to keep them stable (running at 1.050V). They don't get hot at all at these volts. Anyone had a similar issue or know some hints on how i can get the second PCI-E slot to run in x16 mode as well?
