Question I can’t get into bios after changing PLL Ring Overvoltage!

[Fl1cks]

I’m not sure what this setting is so I searched it up but couldn’t really find any information about it. I only found a post where someone had mentioned that he had turned it up to +150mv for his overclock, https://pcper.com/2018/11/gigabyte-z390-aorus-pro-motherboard-review/9/

All I wanted to do was to try giving a little more voltage to the CPU Ring but I couldn’t find CPU Ring Voltage in the BIOS, only this setting.

I saw that this could be turned up to about 950 in the BIOS which gave me an idea of some numbers. I wouldn’t set it way high like that so I decided to start quite small. I wanted to for the last time, try and get the first core to 5.0Ghz with the current voltages and settings that I had so that I wouldn’t get a slight reduction in single core performance by the overclocking. After setting the setting to +60mv I received a blue screen that told me that the computer had to be repaired. I’m unable to get into the BIOS and the screen is just black there. What should I do?

CPU: i7-11700

CPU Voltage Offset +0.030V
CPU Clock Ratio 4.9Ghz
CPU Ring Ratio 4.1Ghz
Core 6 4.9Ghz
Core 1 4.9Ghz
Core 0 4.9Ghz
Core 7 4.9Ghz
Core 4 4.9Ghz
Core 2 4.9Ghz
Core 3 4.9Ghz
Core 5 4.9Ghz
Core Idle Voltage - 1.390V - 1.400V

I got into the BIOS now, about half of it was covered in white and was a little glitchy/buggy looking. I turned that back as quick as possible into the default Auto setting. My guess would be that it was set too low? I was meant to boost and not decrease the voltage of this. Could someone explain to me what PLL Ring Overvoltage is and how much it should be set to?
