Hi, so I just got a used R9 280X and I think it's underperformed.
I already make a post about this here
Then I found BIOS switch and change it to no 2 (I believe it's dual Bios, switch is near CF link), the card seems perform flawlessly.
I can achieve 1150/1550 easy but it runs very hot about >80C at load. Compare to BIOS no 1 can't even run 1070/1500 without crash/artifact, but run at lower temps about 70C full load.
My questions is;
Is it safe? should I worried about it? (at least about the temps)
Why it has same BIOS but different performance?
Should I reflash it? or RMA needed?
sorry about my english
