GPU running at x8 3.0

So, recently I noticed that my GPU is running at x8 3.0. Which is odd because previously it had been running at x16 3.0 but now it currently is not. 

I've tried 

  • Reseating GPU
  • Updating Windows
  • Checking CPU for bent pins
  • Trying different GPU slots
  • Updating BIOS(this one was a bit weird though, keep reading)
  • Trying a different GPU
  • Cleaning the slot

Okay, regarding the BIOS i noticed something rather odd, when I updated the bios, it said that the slot was running at x16 in the bios configuration, when I went into windows it said the same, GPU running at x16(But it was running at 1.1, no matter what load I had put on it). But when I had restarted the pc, all the sudden it is running at x8 3.0 once again. Is there any logical reason behind this? I almost think that it's an ill manufactured bios.

Nvidia cards drop to 1.1 for saving power, nothing wrong

 

as for X8, I'm not aware of this board dropping that for SSDs so maybe it's an install issue. It's not easy to make a long connector like PCIe x16 fit in flush.

It's flush alright. Also, the 1.1 isnt that normal. Because in GPUZ it shows  the max bandwidth usually being x16 3.0, but this time it also showed it being x16 1.1 and when I put a load on it, it remained there
