lspci pstate 07 0f, vbios.rom nouveau, gtx770bios.rom from my gtx770 card

Hello,
Pcie link speed is gen2 instead of gen3

Kernel version: 4.10.0 (same situation with kern 4.9, 4.11, 4.13-rcx, 4.12 =
no
tested/remember)

My motherboard: x79 with 2 slot pci express 3 support

My graphic card: nvidia (msi) gtx 770 4 gb ddr5 oc edition twin frozr (2x f=
an)



Xorg: 7.7+19

Nouveau:
xserver-xorg-video-nouveau 1.0.13-3
libdrm-nouveau2 2.4.74-1

Dmesg (i compiled kernel with nouveau debug level 4 so very much info (clk,=
 fan
etc), i pick just this:
nouveau 0000:02:00.0: pci: pcie max speed: 5.0GT/s
nouveau 0000:02:00.0: DRM: VRAM: 4096 MiB
nouveau 0000:02:00.0: DRM: GART: 1048576 MiB
(clock and pstate are fine and its work)


We are 2 situation:
1- All gtx 770 have this situation (with nouveau)
or/and
2- Nvidia disable using 8 gt/s by default (in forums nvidia: is for all car=
ds
or only for x79 motherboard maybe ? but give option to enable pci3 with grub
and for windows give a small program exe to enable pcie3
(You can default 8gt/s support but you also add nouveau.config=3Dpcie=3D3 s=
omething
as nvidia method is your choice)

In attachment:
- lspci with pstate 07
- lspci with pstate 0f
- vbios.rom from nouveau, located in same path of pstate files
- gtx770bios.rom, bios rom of my gtx 770 extracted with gpuz in windows


ps: in lspci link showing max 5gt/s, but with blacklist nouveau, is show 8 =
gt/s
