my better 5500xt do 27 mh at 53-55 watts.
my lessor ones do 25 mh at 51 watts
I only do memory straps
I never flash bios.
Damn I wish I can get six of those, this is the real definition of power efficiency, two rx5500 will draw 106 to 110 watt @54 MH, damn that's cool and I heard those cards works so cool at good temp
