Got a new GTX 770 yesterday (yay!)

I had two issues upon installing it, and I already solved the first one with some help. This next one, I have no idea what else to do, so I thought I would ask here.

My card can run at 3.0 x16, but it is only running at 3.0 x4. Weird, right?

So, I went into the BIOS under PCIe config, and tried Gen2, Gen3, and Auto settings. Same result. I pulled out the motherboard manual. I have the card in the top slot, which it says is PCIe x16. I have the latest GPU drivers and the latest version of BIOS.

Questions:

#1 Any idea how to get the card to run at 3.0 x16, or what might be making it stay at x4?

#2 If I can't get to x16, how big a deal is it, performance-wise?

Thanks.

I'm gonna guess "Power saving features may affect the results displayed."

Congrats on your new GPU.

#1: Set the BIOS to Gen3 of course. It won't stay at x4 when you are actually using the card. If you aren't doing anything heavy it will go into a power saving mode [Idle Mode pretty much]

#2: You don't want to go below x8, but I believe you card is simple in a idle like mode. Just press the "Question mark" [?] next to the Bus Interface info. You should see the info quickly jump to x16 @ 3.0.

Otherwise you can run a game and check the Bus Interface info.

I have every power saving feature I can find in Windows and the BIOS disabled.

I press the question mark, and a render test comes up, but nothing changes with the Bus reading. I've also popped out of Unigine Heaven with GPU-Z open, and also run a system-wide stress test with AIDA64, and have never seen it go above x4.

I guess as long as I don't notice bad performance I shouldn't worry too much about this?

Have you checked in the bios in the advanced menu, under DMI configuration?
