If you need to use this product correctly, please choose the motherboard correctly; Many motherboards share PCI E channels. Make sure the motherboard supports PCI E split function, but cannot recognize so many M.2 SSDs or devices. Please remove or replace other PCI E devices, such as graphics cards, expansion cards, onboard NVME SSDs, etc. 2. CPU support is required, CPU must have enough channels, generally low end CPUs do not have enough PCI E channels so may not support, When selecting CPU, you can refer to the motherboard introduction for correct selection.
