1. PCI-E 4X
2. Please install WIN10 system. WIN7 needs to install driver, but the speed cannot be improved.
3. Motherboards that do not support NVME protocol cannot be used as system disks, but only as storage disks

INTEL, motherboard chipset:
B250 B150 H170 Z170 generally supports NVME as long as the motherboard has M. 2 interface.
Z97 partial support, specific check-there are NVME options under the official website or BIOS
B85 Z87 needs to update BI0S support, and some conscience factories have already provided BIOS supporting NVME, such as ASUS
And Huaqing, etc., if the official does not have it, they will change BI0S by themselves, and the specific online tutorial needs to be fixed
Hands-on ability, risk of damaging motherboard. (Most B85 s do not provide M.2 interface, so we can use our shops
M.2 to PCI-E adapter card)
Older motherboards can basically give up or ask customer service for ways to install them. Lets make a detour.
