Rampage V Edition 10 PCIE Question

Shashankdatta
Level 7

Hoping for some insight.

I am using Rampage V Edition 10 with i7 6800k, 2x GTX 1080ti SLI

I know that I have 28 PCIE lanes available and x16/x8 GPU configuration is what I was thinking would happen but for some reason I have a the second GPU running at x4 link speed instead of x8.

GPU #0

GPU #1

I also have a Elgato HD60 PCIE capture card that is PCIE v2.0 card connected to PCIE x4 slot.

So lanes 1 (GPU), 3 (Elgato), and 4 (GPU) are occupied. It seems to me that I should have plenty of lanes / bandwidth to cover everything I am running at full speed. Any insight would be appreciated.

I might have made mistakes in calculating the available number of CPU lanes and the system is functioning as expected, clarification is appreciated. 

Here's the motherboard's manual for your reference: https://dlcdnets.asus.com/pub/ASUS/mb/LGA2011/RAMPAGE_V_EDITION_10/E11861_RAMPAGE_V_EDITION_10_UM_V2... 

Thank you in advance
