Unrealistic Wattage Shown and Fan % missing

Hi,

I have a Mining Expert and just cannot seem to get any GPU beyond eight recognized. I do have a mixed brand of 570’s and 580’s. Every time I add more than eight GPUs, the very last GPU has no fan percentage and no watt shown. For example, If I have nine GPUs, the 9th GPU has no fan percentage and no watt shown. If I have ten GPU, the 10th GPU has no fan percentage and no watt shown while the 9th (no longer last) show percentage and watt. The GPU that does not have the watt and fan info does not have its hash rate shown and accounted for either. Note:http://forum.hiveos.farm/uploads/editor/hg/t769gxj5wnt8.jpeg

Also, the very first GPU always have this huge watt shown. See screenshot.

Anybody has any suggestion as to what could be the root cause? I note that during boot up, I see some of these messages:
[ 28.639415] amdgpu 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff

[ 28.640547] amdgpu 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff

And from dmesg, I see a bunch of these…

What do they mean? Thanks.

I did not overclock. Everything stock right now. CPU is a i3-7100 and using xmr-stak.

And GPU quickly heat up. If I have just eight GPU, no heat-up. Using only AMD 570 and 580 right now.

Okay. Changing to use Gen2 resolved issue where huge watt is shown. As for the last GPU always not showing fan % and not being recognized, rebooting help. Shutdown and turn on will not work. Just rebooting the OS cause all GPU to be recognized.
