Hello,
Is it possible to get a mining rig and install different GPU brands to mine? For example I want to buy a rig and then install AMD(550, radeon 6800xt) & Nvidia (2080, 3070, 3090). Would it be possible to have different GPU's hooked to a rig?
its doable but bit hassle to set up, even same type gpu the config will be different, you can use hw monitor to find right config, i meant stability and efficiency, and dont forget about heat and ambient temp.
overheated may bring crash to memory, yes you can use gpu watchdog to restart automatically, but in first ride i would suggest doing normal things to monitor your rigs.
