I did a GPU driver clean reinstall (driver version 20.5.1)
I checked the 12v, its above 12, but sometimes it dropped to 11.95 something. I think the voltage is fine. (maybe i am wrong, i can post the sensor report here if you need)
This is my gpu GIGABYTE AORUS Radeon RX 5700 XT 8G Graphics Card, PCIe 4.0, 8GB 256-Bit GDDR6, 2010 MHz Boost
Right now i set it to 1150mv core voltage and 1900 Mhz core clock ( i set it to 1200mv, and it triggered the PSU protection once)
