Another bump!

I don't think the BIOS supports it right now, but Asrock seemed to imply that it might come with a future BIOS update?

Bump!

I asked about this some time ago and ASRock_TSD suggested that some board from the 100 series would have bifurcation support. Is this still true? Or do I have to give up on this?

I know that the ASRock's X99 ITX board supported bifurcation with a BIOS update so I would guess that there must be some setting in the BIOS that allows for this. I don't know however if it would already be present in the Z170 Gaming-ITX/ac's BIOS.

I think you may have to wait for ASRock_TSD on this one or alternatively you can create a support ticket and ask tech support directly.

Good question. That PCIe device in your picture, is that some type of riser card, or a PCIe x16 lane "splitter" of some sort? A little of both I suspect.

I've never had personal experience with what you are asking. Plus I've never seen a forum post besides yours on this topic, sorry to say.

I don't know if bifurcation requires a UEFI/BIOS option or not, and if it is enabled outside of the chipset, meaning in control of the mother board.

I'll try to find more information on this for you.

Any idea about support for this?

Hi,

I'm wondering if the Z170 Gaming-ITX/ac supports PCI-e bifurcation of x16 lanes into two PCI-e x8 slots. The Z170 chipset supports this, but I'm curious if the Asrock implementation does. If so, using something like this should be possible:
