When I checked cpu-z I noticed my pci-e bus was running pcie 3.0 instead of 4. I currently don't have a gpu so I am using the UHD 750 integrated gpu, and was wondering if thats why its running in pci-e 3.0. Other cpu-z screenshots of 11th gen using the igpu showed the pci-e bus spec at 4.0. Possibly mobo or cpu problem? Ran memtest no errors, temps are in check, not sure what is going on, any help would be appreciated.
