I am currently in a process of troubleshooting my GPU ( 770gtx ) + motherboard ( asus P8Z68-V LX )problem, I have managed to identify the main cause of my problems and in a very strange and idiotic way it seems to be corelated with switching powerstates while card is plugged in the motherboard's main PCIe 2.0 slot ( the x16 one, the x4 secondary has no problems ).
So, when chaging power states 2 things happend : My GPU changes it's performance level ( core clock, memory clock, etc.. ) and switches from it's idle PCIe 1.1 to PCIe 2.0.
Is there any way to force a constant PCIe 2.0 usage even if it's idle ? The only way I have done this it's through nvidia inpector by forcing to use the custom performance level 1, but that also forces constant high clock levels ( I know I can decrease them but it is not my point ).
Oh, and also from power options the PCIe saving power is set to off.
Thanks for your time
