Hello, I have some problems with my RX 6800. So yesterday I got my first mining rig with one GPU, I tried at first to do the overclocks from [Mining Chamber](https://miningchamber.com/gpu-mining/rx-6800-mining-settings/), it worked for 20-30 minutes until my screen turned completely green, and the only way to fix it was to unplug the rig or turn off the PSU because the power button would not work and I couldn’t do anything with the mouse or keyboard.
Today I tried these overclocks: [Overclock 1](https://youtube.com/watch?v=GUGJiuSWTJI), [Overclock 2](https://www.reddit.com/r/NiceHash/comments/lqrw8t/radeon_rx_6800_mining_settings_brand_new_card_had/), [Overclock 3](https://www.youtube.com/watch?v=jgmY3JmpmNw). They did the same thing as yesterday and I had to switch off the PSU while the rig was running multiple times.
But now I have a problem and that is no matter what kind of overclocks I try when I start the miner my screen would start flashing green and if I don’t close it immediately it would turn green and the same story as before.
The only thing that I changed in the BIOS was to set the PCI-E speed to Gen 2, and 4G decoding was already on.
