rusTORKSince it's popped up, i would like to ask question:My system have got both Intel i7-3630QM (Ivy Bridge) which support PCI-E v3.0 and NVIDIA VGAs (GeForce GT 650M and GTX 1080Ti) which also support PCI-E v3.0, but GPU-Z only showing me PCIe x16 2.0 @ x8 2.0 (on both cards).At the same time, HWiNFO64 showing me, that Root Ports have got PCI-E v3.0 (both, for each card), but VGAs again - only v2.0.I even founded Root Ports in BIOS (PEG0-GenX, and PEG1-GenX), double check it's correct ports (B0:D1:F0 & B0:D1:F1) and set them Gen3. No results.I updated drivers for Root Ports from Microsoft Catalog (was something like 2011, now they are 2016). No results.

bcavnaughWhat Motherboard or Laptop is this Intel i7-3630QM CPU installed on/in?
bcavnaughMixing that old a graphics card GeForce GT 650M and GTX 1080Ti may also be your issue.
rusTORKbcavnaughDon't rely on GPU-ZUse the NVIDIA Control Panel System InformationChecked there too - both have got "PCI Express Gen2". bcavnaughWhat Motherboard or Laptop is this Intel i7-3630QM CPU installed on/in?Laptop is Lenovo Y500, MB is LCFC LA-8692P. It's very unique build...More information here: h t t p s://egpu.io/forums/builds/2012-15-6-lenovo-y500-evga-gtx-1080-ti-sc2ultrabay-adapter-win10/ bcavnaughMixing that old a graphics card GeForce GT 650M and GTX 1080Ti may also be your issue.It's possible, yeah. But a bit newer model of same laptop Y510p have got everything working fine (PCIe x16 3.0 @ x8 3.0) - there will be link on it too.
bcavnaugh Can you Force GEN3 in the Bios?
bcavnaughAlso error 43 can be caused by having CSM Enabled and not running 100% UEFI on the Bios.
bcavnaughThe Scope of this Project is Huge.
