Trying to put together a purchasing plan for PCIE 5.0 MCIO stuff for a 12 GPU (single socket) build. I know about C-Payne, and recently learned about Shinreal, but this MCIO PCIE receiver does not look like any of their offerings.
How’s the signal integrity on those motherboard MCIO ports? Can you reliably use a 75cm cable to connect a GPU at PCIE 5.0 x8 speeds? Trying to avoid purchasing extra retimers/redrivers (as far as I am aware those only come in PCIE form, does there exist inline MCIO retimers/redrivers that attach direct to cable?). I’m eyeing the Turin motherboards from ASRock Rack at the moment in-case there’s differences between board manufacturers that I am unaware of.
