Maybe it was in this discussion that I read that this mobo (Z370 Aorus Gaming 7) only allows their card to use PCH lanes. I thought the point of Thunderbolt was that it was tied directly to the CPU.
The GPU is on the PCIe16x -The GC Alpine Ridge is supposed to go in the very last PCIe slot. It's not sharing lanes, but if I moved it, it would. To get your money's worth out of a dedicated GPU, it needs to be in that x16 slot. In addition, my GPU is double-width. What's odd is that the GPU shows in the system report, but not in the list of PCI devices. The performance from the card is very good. Good benchmarks, etc. The Apollo 8 also performs well and the latency is very low. I've been able to repeat the "half-speed" performance of the Thunderbolt BMD Multidock 2 on a real 2012 QC Mini (6,2) -it's only a few MB/s slower than when it's on the Hack and the Apollo is daisy chained to that. I'm using real Apple TB2 cables and Apollo TB3 to TB2 dongles with identical dongle and cable firmware.
Q: Has anyone considered that this problem lies inherent in Thunderbolt cable firmware? There's a lot of fancy stuff inside of that connector.

i have your same cpu (i7 8700k) and graphics, how do you make the gpu and the cpu graphics works together? I tried a lot of configurations...
Using the Bruce x test in FCPX, the speed goes well only when disabling the UHD 630...(just using the rx 580) but I don't have quicktime screen recording, etc (but I can reproduce Netflix, iTunes and other DRM needed applications...)
thanks in advance
