So I know that a 16x has all the pin going the length of the pci-e slot, but is x8 just half of that?
I guess my question is: in an x8 slot, is the second half of the slot just a placeholder for the card to sit in? Because I bought a Maximus IV Gene-Z with a bent pin in the x8 slot, but when I got it, the bent pin was at the end of the x8 slot where I don't think a pin should've even been.
Or is there usually a pin at the end of x8 slots?
Yes, the second half is just blank. They do usually have 1 pin in the end, which is not used for anything officially, perhaps just for identification for the motherboard, so it can tell when you have a full length card plugged in.
