Q

Your motherboard does not support up-plugging for PCIe adapter cards. Which of the following is true?

You can put an x8 card into an x16 slot, but it will run at x1 speed

You can put an x8 card into an x16 slot, but it will run at x8 speed

You can put an x8 card into an x16 slot, but it will run at x16 speed

A

You can put an x8 card into an x16 slot, but it will run at x1 speed

The x8 card won’t completely fill the x16 slot, but it will work at x8 speeds if up-plugging is supported by the motherboard. Otherwise, the specification requires up-plugged devices to operate at only the x1 rate
