I have qty 60 of Z170X-UD3 motherboards. In 10 of these, I am running INTEL I-7 7700K (Kaby Lake) processors and 2133 memory. I also run DUAL GIGABYTE RX 580 (GV-RX580GAMING-4GD) on all of of these. Before I upgrade 40 more of these, I need highest INTEL processor that will run on this board? What board bios to install?
