The MSI Pro Z690 only has four PCIe slots for 4 graphic cards, if you want to use the extender its fine but I can't tell if it will support up to 10 graphic cards, by the way if you are willing to spend dollars on this Z690 why can't you just buy a mining motherboard like B250 or other? Or you already have this Z690?.
Yes, I have this motherboard already which I use for gaming. I tried buying a second motherboard geared towards mining but it was DOA and the quality and seller accountability now seems risky to continue to pursue in this current market environment.
I also found that many bitcoin specific motherboards are 3x+ the price of the z6960.
I should clarify. I am able to get 10 GPUs running, but trying to get to 16 with 4x1 splitters.
Is there a motherboard chipset you could suggest for 12gen CPUs?
