Hi,
I have the same ASUS X570 Prime Pro ATX AM4 motherboard and the RM Fireface 800 and want to connect this device through Firewire, but i have issues with two PCI Express FireWire cards. We have tried the following PCI Express cards:
- Lycom PE-107 (http://www.lycom.com.tw/PE107.htm)
- Exsys EX-16415 (recommended by this topic, so bought this one)
But neither of these are working. If the cards are inserted in the PCI Excpress slot, then the pc won't boot. Not even in the BIOS. This motherboard has LED's so you can see how far the pre-bios-boot time is. It hangs on the VGA LED, so i think the motherboard sees this cards as a VGA card. It can't see the card. If i remove the FireWire card, then the PC boots normally. I have read/tried to change all the BIOS options (boot, secure boot, CSM compatibility, but no change). I have another new PC with motherboard Gigabyte B450 Aorus Pro, both Firewire cards are working fine. In my main pc (with the ASUS X570 PRIME PRO motherboard) i have a Ryzen X3900, witch is not supported by the B450 Aorus Pro, so changing the motherboards is not an option.
Do you know a working combination of a PCI Express FireWire card with the ASUS X570 Prime Pro, or did you set a specific BIOS option to let the Exsys EX-16415 work?
If not, do you know if there is another X570 chipset motherboard that do work with one of the given Firewire cards?
