Looking for: Asus Z10PE-D8 WS modded bios w bifurcation

[icodeforyou]

Hi all,

I recently acquired one of these boards, and I figured I would share my modified BIOS (attached) since this thread has been helpful to me. I have enabled bifurcation options for all the slots connected to CPU2 (Slots 5, 6, 7). The settings can be configured from within the BIOS and are named in a coherent fashion (IntelRCSetup->IIO Configuration->PCIEX16 Bifurcation).

I did try to enable bifurcation for the slots connected to CPU1, but I didn't have any luck. This may have to do with the fact that they are routed through switches for the x8/x8/x8/x8 vs x16/x0/x16/x0 functionality, but I didn't investigate further.

Let me know if you encounter any issues, etc. or if this is useful to you.

Thanks!

Thanks very much for that contribution! Just one little question: Slot 6 is not 16x, or is it? So what would the bifurcation option be there? 4x/4x?

I am personally quite happy with bifurcation on the two 16x slots for CPU 2. Works just great for me now.

But having the BIOS option to switch it on/off is a nice addition.

Right: Slot 6 only has 8 lanes routed to it, so the options in the BIOS for bifurcation are x8 or x4,x4. Slots 5 and 7 have the option of every possible permutation of their 16 lanes.

Yeah, I don't really have a lot of reason to try to figure out how to enable bifurcation on the remaining (CPU1 connected) slots either- having two full x16 slots and an x8 slot gives pretty good options.
