X299 Taichi XE PCIe Lane distribution

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Good morning guys,
It's a pleasure to be part of this forum!

I would like to move on a X299 platform using the X299 Taichi XE, but because I have special setup requirements, I've few questions:

Could you explain the PCIe lane distribution with a 44 Lane CPU? I would like to have this configuration:

2x TITAN V in full 16x mode, with NO SLI
1 Samsung 970 Pro M.2 using x4 CPU lane for the O.S.
1 Intel 900p PCIe x4 using x4 CPU lane for caching video, etc.
The Thunderbolt AIC Card using whatever, PCH or CPU lane.

Is it possible with this motherboards?

Thanks a lot for any reply!
