This is for that specific slot, but otherwise I couldn't find anything.
I could force the second x16 slot into x4, but my first x16 stayed at x8 3.0 speed, despite enough PCI-E lanes to make it happen.
I dont think what your asking is possible
the CPU has 20 lanes
the rest are provided by the CHIPSET for USB & SATA
you cannot set individual lanes that are not supported
x16 single
dual x8/x8
+ m2 x4 ssd they are the only ones supported by your MB

Ah I was thinking CPU provides 24 lanes, my mistake
It would be quite handy if it did, but not many boards support it,
here is an interesting read if you get time, your actually not missing out on much by running at x8 anyway

thats one of the only differences between the C6h and c7h , unfortunately for the OP the 2nd and 3rd slots are locked at x8 & x4 respectively whilst the c7h has the option.

You can get around this by forcing slot 4 into x4 mode (I think it says its intended for RAID config) - sadly that doesn't put slot 2 into x16 mode - either because there are not enough lanes or the mobo bios is stupid ...
