I have some "magic" on my laptop and need an advice.
I have very cheap mPCI-E adapter (12$, like this https://ru.aliexpress.com/item/2016-PCI-Express-1X-and-USB-to-Mini-PCI-express-High-Quality-Mini-Pci-e-Adapter/32610100408.html?detailNewVersion=&categoryId=200003088) and it's must support only PCI Gen1 (2.5 Gbps). I also forced my PCI port to use Gen1 (PCI 1.1 x1).
When i'm not load my eGPU - it says that work on 1.1 x1. But when I play games - HWiNFO and GPU-Z says that my GPU (GTX 750Ti) use PCI 2.0 x1 with 5 Gbps. But it is probably impossible...
I use GPU with optimus on internal laptop screen. Is my PC lie to me? How can I test real PCI-E bus speed of my eGPU?
P.S. Sorry for bad english.
