Recognition

Hi! I had problems with coffee and my macbook pro 2015, I took out the ssd hard drive, bought a PCI x4 adapter, put it together and connect it to my computer PCI x16 slot. I have windows server, but it doesn't recognize it... Any help please¿? Thank you!!! :)

So I recently purchased another EVGA GTX 950 so that I could run it with my other EVGA GTX 950 in SLI (because it looks cool tbh). But after purchasing another motherboard because the one I originally had didn't support SLI and after installing everything I'm not noticing any difference in FPS...
