The system I outlined in my other post [0] has ten GPUs and does not require dual socket CPUs as far as I'm aware. It could likely scale easily to 14 GPUs as well (assuming you have sufficient power), with an x8/x8 bifurcation adapter installed in each PCIe slot. This is pushing the limits of the PCIe subsystem I'm sure, but you could also likely scale up to 28 GPUs, again assuming sufficient power, by simply bifurcating at x4/x4/x4/x4 vs x8/x8.

I think it should work as-is with the components listed, but if you disagree please let me know!
