I recently upgraded my rig with a sapphire r9 280x that I bought used.
Problem is that I am only getting areound 16MH/s. I even completely wiped my ssd and installed thenewest available drivers. No chages though. The card is running pretty cold. Only 60° at 30% Fan speed.
Does anyone have an idea what the problem might be? Did I maybe just get an r9 280 (non X)?
