I have a 5080, it's a galax 1-click oc, not awesome, not bad, it's a decent, close to msrp model.
For it's oc i ALWAYS use msi afterburner, and it always played out well, +400 core and 3000 on mem clock, maxed out power limit, hit constant 9600 points on steel nomad dx12.
Yesterday i stumbled on a post about Mvolt, and i decided to give that a try, hoooooly.
Stock: 8600
Oc: 9700
Mvolt max result: 10200
Mvolt undervolt: 9900
