You can manage 15 cards without running out of PCIe lanes by organizing your setup efficiently.
This question clarifies the process of managing lane allocation. It seems no motherboard allows switching from x16 to x1. Using 1 to 4 slots would consume 16 lanes unless you can split further down to x4 per slot, which would leave very little capacity for additional GPUs. You’re wondering about the details and whether this scenario has been tested or is just a hypothetical.
