GPU mining with a $29 AMD Radeon R9 380X 4GB in 2022
this took quite some doing, but we got the card mining on an older HiveOS release and OpenCL drivers!
ethereum classic 21MH/s -106w
ergo 41MH -80w
Kaspa 86mh -88w
not efficient, but still cool to see that 7 year old hardware can still do something
card was purchased from neardgearz.com not affiliated but had a great experience.
