Welcome to the EVGA Forums
1) Depends on what CPU & other Hardware is in your MB & what slot the GPU is in
I'd test with GPU-Z
Remember to turn Windows 10 Fast Startup OFF, when upgrading drivers, firmware or hardware
[It does this by putting the PC into hibernation instead of "fully shutting down."]

Hi Cool GTX, thanks for the prompt reply!
I did disable fast startup, everything is at performance mode including bios;windows. GPUZ screens attached in the first post.
Sorry I guess i didn't explained it properly, I just have one nvme m.2 installed (pciex 4x) and the video card is at pciex16_1 (slot 1) on the first slot that it supposed to be for max link speed.
The motherboard sets video card to 1.1 (2.5GT/s) mode instead 3.0 (8.0GT/s)>RANDOMLY.
Cold start usually comes at 3.0 (OK) and if restarted, returns to 1.1. But again this is totally random.
When it is at 1.1 mode it will never scale up to 3.0, no matter if rendering or playing games, this is not a power saving feature as I changed and messed with it all in both Windows and BIOS and monitored it. Looks more like a bug due sometimes booting in 3.0 correct mode, so not hardware limitation either.
The video card is old and does not have UEFI support, has to launch in CSM. But it always worked at 3.0 in my previous system and I also tested in brother’s PC to guarantee. On those systems it recognizes at 3.0 without issues even after restarting many times so I know it’s not a video card issue and indeed this new Strix B360-F motherboard that is causing it.
So I want to know if not having UEFI support is making the motherboard set it down to 1.1 thinking its "super old card" (cof cof), but still doesn't explain why sometimes it boots at 3.0 mode.
I want to update the vbios to UEFI and test to discover if motherboard is faulty or not as it is brand-new and I could warranty.
This is all my troubleshooting steps:
Performed fresh OS install, checked all bios settings (pciex speed gen1 2 3, auto) nvme modes settings, loaded defaults, disabled secure boot, fast boot etc. Cleared cmos, changed windows power management for PCI-ex (savings /off /performance mode) disabled fast startup . Removed card from slot and checked/cleaned, re-seated, system works fine and there is no signal of damage in either pci lanes on the mb and video card, everything looks brand-new.
