Hey everybody!

So I have 2 GTX 1080 Strix in SLI and I noticed after doing some benchmarks that the cards are only running on PCIE 3.0x8 3.0 even though it reports that it is capable of PCIE 3.0x16 3.0.

My MOBO is a Maximus IX Hero and my CPU is a 6700K with 32gb of RAM.

I was wondering if this due to some bottlenecking happening or could it be just natural to SLI configurations?

I would like to hear your thoughts.

I see... does that also explain the more than usual heat generation of my CPU?

No. I would recommend you create a new thread to discuss that.
