Windows 10
6 x RX470 4GB
Latest AMD driver.

Settings on Wattman are
Memclock 2000 - 900 mV
Coreclock 1050 - 900 mV


When I check GPU-z for my watt consumption.
I have one card : VDDC 50W & VDDCI 30W 0,89 mV.

And the other 5 cards are all VDDC 60W & VDDCI 40W 0,88mV

Why are 5 cards consuming 20 watts more per card ?? But shows lower undervolt ? ...
