Question Asrock x299 Taichi PCIe slot disabling?

[horse computer]

Hello,

I'm having an issue with my Asrock x299 Taichi [Manual].

I got it a week ago and have so far attempted to use its sole PCIe 2.0 slot (in the manual listed as PCIE-4) for a 1394a firewire card and for a Slate VRS8 audio interface card.

In both instances, when any interface is plugged into either card and powered on, either Windows will freeze entirely a few seconds after logging in (if Windows is booting), or Windows will fail to recognize the interface in any way (if Windows is already loaded).

My build is pretty full of hardware items (see here), but I don't see anything in the manual about any other hardware disabling the PCIE-4 slot.

Does anyone have any insight or advice on this? Appreciate it.

Which version of Windows 10 are you on? Are you on the latest BIOS for your motherboard? As far as the lanes on your CPU is concerned, you've got 44 lanes at your disposal without any discrete GPU. Likely that the PCIe x1 slot derives it's lanes from the chipset.

Hi @Lutfij, thank you for your reply.

For BIOS, I haven't changed it since opening the mobo, but I will update you with the specific version as soon as I can check for myself.

Regarding the rest; I do have a discrete GPU installed, a GTX 1060 in PCIE-1. When you say the "PCIe x1 slot derives its lanes from the chipset" - what does this mean exactly? Is there a conflict between the GPU in PCIE-1 and the Slate card in PCIE-4?
