Is there a list or a way to tell if an AMD card can be undervolted before buying it?

no but you could buy mine

https://bitcointalksearch.org/topic/sold-selling-some-r9-390s-xfx-sold-1579698

all are the same and they all under volt.

and you could get then new from best buy

if you use amd 16.7.2 and claymore miner they will do 27-30 mh with undervolt.

the amd settings have overdrive for r9's and wattman for rx 480s

I ended up buying a mixture of 390 cards a while back, only to realize it seems none of them support undervolting (Tried MSI Afterburner and Trixx)
I have an old R9 290X Reference card back when Litecoin mining was hot on them. It can undervolt -100 and works amazing, in this heat it's as good as my 390.
What cards do you use that you can undervolt? Is there a custom bios for the 390s that allow this? I'm also interested in the 400 series, seems they all can be undervolted?

i undervolted my R 9 380 its efficient,low power consumption
