Using the PCIE 16_3 on a single GPU config

The motherboard recommends using the first slot available but I would like to use the 3rd slot so I can see the ROG logo in all its glory.
Since they are both 16 slots I would imagine there would not be performance loss, but since the bios says the 1st slot is ideal, I wanted to know.
Will I lose performance by using the 16_3 slot?*

Hi, there won't be any discernable difference between the two slots. Easy enough to test it if on air. 🙂

I’ve recently been testing different pcie slots benching my Titan v and only found marginal error of difference between them ( test related difference) on the rampage vi extreme.

I can confirm this. I have to use 16_3 for my gpu since my case had limited room for the water pump. Didn't see a difference here with a 1080 gtx.

Your good so long as the slot you plug it in is 16x.*
The recommendation for top slot is because of the shortest traces.*
