It's good to see somebody got this board to work. I have problems with this board. I have a tons of PCIe bus errors. Are you sure you haven't changed anything in the bios? PCIe bus speeds auto or gen2, or above 4G MMIO? Also do you use the IGFX or one of the mining card?
Could you share your settings?

Connect a monitor to the GPU connected to the 16x slot; nvOC and rxOC do not currently support integrated graphics.
