I did my own real world test,Switched from x8/x16 to x16/x16 by moving my NVMe SSD to the PCIE 2.0 x4 slotRunning on an ASUS 3440x1440 G-SYNC monitorMSI Seahawk X GTX 1080 x2 (SLI)Ran Wildlands: Ghost Recon at "very high" presetx8/x16 SLI I got 76 FPSx16/x16 SLI I got 95 FPSI was surprised to find this difference but I double checked that the environment was identical and this is the result

I had a feeling it was overdoing the voltage, I've only ever done it once before on a 4770K manually, so not too much experience. Thanks guys!

I have the ASUS x99-A II motherboard Intel 6850K CPU cooled by Corsair H115i GTX MSI Seahawk X GTX 1080 SLI Corsair 860i PSU 32 GB of Corsair Vengeance LPX RAM i started up ASUS' AI Suite 3 software and the auto tuning feature apparently started overclocking the CPU automatically, never knew there was software like this out there but I let it finish. Anyone used it before? Is it reliable? It gave me a 27% overclock at 4.6 GHz with 1.499v, which seem a little much to me but nevertheless during the whole process the highest temperature was 77° C. Any thoughts?

Yes guys as I stated I did look at the manual and bios, and as I wrote in the original message it's running slot 1 at x8 because it's sharing the bandwidth with slot 4 which is used up by the SSD, I just wanted to see if anyone has any real world evidence that a GTX 1080 still isn't very different with 8 lanes vs 16 lanes especially with modern games, that's all. Thank anyway.

I have the Asus x99-A II motherboard Intel 6850K with 40 PCI lanes Nvidia GTX 1080 SLI with HB bridge Intel 750 PCI-E SSD Per manual instructions I installed GPU 1 in PCIEX_1 slot, GPU 2 in PCIEX_3 slot and the SSD in PCIEX_4 slot, then I noticed GPU 1 was only running at x8 lanes! Later found out that PCIEX_1 & PCIEX_4 share bandwidth! I'm not sure any other configurations are possible since PCIEX_2 slot sandwiched between the GPUs is only Gen 2.0 and that shares bandwidth with a whole bunch of other features. I've read everywhere that x8 vs x16 is utterly insignificant but I've also read that it is more significant with modern games and especially modern GPUs like the GTX 1080. I'm even more concerned since it's the PRIMARY GPU running x8 and not the secondary, and many games don't even use the secondary GPU which would just be sitting there with all of its x16 lanes! Any suggestions?
