Default what is 1 (x8) PCI-Express (using x16 slot)?

Hi All,

I am looking at a motherboard that says it has an:

(x8) PCI-Express (using x16 slot)

What is this? Can I install a PCIe 16x video
card in it? Will it only run at half speed?

Many thanks,
-T

It is geometrically a 16x PCI express slot (in that it will physically
accept up to 16x cards). However it only has 8 PCIe lanes wired. Yes you
can insert a 16x video card in it, and as you correctly surmised it will
operate with only those 8 lanes (and at only half the bandwidth).
