Please install for WlN10 system, for WIN7 needs to install the driver, the speed cannot be improved.3. The motherboard that does not support the NWWE protocol cannot be used as a system disk, only as a storage diskFor INTEL Motherboard Chipset:B250B150H170Z170, as long as the motherboard has an M.2 interface, it generally supports NVME.For AMD Motherboard Chipset:The support of B350X370X399A320 is not supported before, which means that NVME must be supported by for RYZEN CPU motherboard.Package List:1 xU.2 Adapter 1 x Cable5 x ScrewNote:This card can support 2.5inch for SATA hard disks, and for SATA cable must be connected to the king board for SATA port when using it. Note that the motherboard must support PCIE3.0 to reach high speed.
