Welcome to the forums, newcomer!
You're advised to parse the specs to your system, in full, so we know what you're working with. Often times lanes can be shared when populating a pair of ports on a motherboard or that the processor doesn't have the lanes to speak of. If you will, please parse your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS: if on Windows 10, include OS version(not edition)
Additionally, include the make and model of your PSU and the BIOS version for your motherboard.
