Video card will only run at 8X

post #1 of 8
Thread Starter 
Just built up an Asus Maximus IV Extreme-Z. Everything is running smoothly so far, but I noticed that my video card is running at 8X not 16X. Video card is in slot 1. And I have a sound card in slot 5. Does the top slot drop to 8X if you have another slot populated? Just want to check if I should be running my sound card in a different slot.

When another slot is populated, it will drop it to 8x - you most likely won't see any difference in FPS between 8x and 16x as the bandwidth isn't fully saturated.

Shouldn't that board run x16 - x16?

No, expansion slots are as listed: 4 x PCIe 2.0 x16 (x16 or dual x8 or x8, x16, x16)
1 x PCIe 2.0 x4
1 x PCIe 2.0 x1

i.e. anything in the 1st X16 slot will drop to X8 when something else is inserted

I don't see what it matters?

A 570 does not come close to maxing that PCI-E slot out. Even a 590 does not either.

This is the board expansion slot 4 x PCIe 2.0 x16 (x16 or dual x8 or x8, x16, x16).

Your board has NF200 which is capable of x8/x16/x16

Move the card to PCIe_X16_2 and the sound card to PCIe_X16/X8_1
