there is 2 m.2 slot as well can we run 8 GPU on this?

Also i have one rig running nvOC on sandisk ultra usb 3 stick 16gb all seems running well, one issue i have is the boot takes almost 1 min. compare to simplemining its big difference. any idea how can i improve the boot up time?
maybe a 32gb faster usb sticks?
