I never figured out the dsdt issue that prevents me from using 2 RME raydats and a UAD octo together. It seems impossible to find a PCI configuration that works. This was problematic also on the C612 chipset with the dual xeons but I was able to fix the dsdt there.
I was able to find a configuration where it booted and all 3 cards showed up in ioreg and the system profile but the system only saw one raydat and the apollo. I was able to find a configuration where both raydats were recognised but then it was impossible to find a slot for the UAD octo. So it's just 1 raydat and an UAD octo for now.
I'll keep hacking at it but I am stumped for the moment. Might be time to sell everything and get a thunderbolt madi configuration but it's expensive and I need to get some music done.
Maybe you run out of Lanes.
Don't know what everything is built into your rig but would be my first thought.
On my build I use all 44 Lanes, If I try to add another card it acts a little bit like your System, If it boots up even...
I use my UAD Octo on the last PCIE Slot but I use the Designare and not the X299 Deluxe.
