if you have SLI, either both slots will run at 8X, or one will run at 16X and one will run at 2X, unless you have a certain board which supports 16X for both slots, although that doesn't really make much of a difference
having it at 8X/8X is recommended over 16X/2X

if you have a single card, it will run at 16X

The jumper settings for a single card are on page 69 of your manual:
http://www.dfi.com.tw/Upload/Manual/...0847505101.pdf

The SLI settings are on page 68.

When in single card mode, the top PCI-E slot is x16, the bottom one is x2.

Not that I saw in the manual.

It's either the top or x2.
