CO NOT WORKING AFTER BSOD [SOLVED]

TLDR:
-Set PBO and CO to auto
-Enable memory fail protection
-Save changes and restart
-Set up PBO and CO
-Save and restart
CO should be working again.

Notes:
-If memory fail protection is disabled or not available, might encounter bootloop; if so do a CMOS reset
-After setting PBO and CO to auto, you might not see these changes in the prompt when trying to save and exit - Proceed.



Initial Post

I've got a situation. I'm totally new to tweaking anything to do with CPU/GPU besides unbinding power/temperature curve on MSI Afterburner to reduce thermals while keeping as much performance as possible. Anyway, the other day, I got a BSOD after messing with PBO and CO.

(Core#(single rank/multi rank))-CO:
C7(1/1)-30
C6(1/2)-30 (I am aware that 2 cores are ranked as strongest for single thread but that's what HWiNFO64 showed)
C0(2/3)-30
C3(3/4)-25
C4(4/5)-25
C2(5/6)-25
C5(6/7)-20
C1(7/8)-20

I sought guaranteed performance for gaming so went with +10% on what someone suggested in one of their posts here:
PPT: 125W
TDC: 83A
EDC: 127A

C states: off(temps werent consistent so a little trade-off)

CPPC: on
CPPC Preferred Cores: on

This configuration got me pretty much sustained boost of around 4200-4400MHz with temps hovering around 50°C at idle, 60-70°C while gaming and 90°C in OCCT.

I ran this for about 4 hours with mixed use till BSOD. About an hour before that, I experienced occasional frame skips. Now, after I got BSOD and rebooted, I noticed my temps dropped and sustained clock gone, not just CPU but GPU as well. I had to restart MSI Afterburner to OC GPU again. CPU is where I struggle, even a CMOS reset and BIOS reconfiguration didn't help.

Checked dump, GPU driver crash, msedgewebwiew2 tried to write to an invalid memory address.

I would suspect my 600w bronze PSU(I know... I got the PC prebuilt as it was cheaper due to inflated GPU prices) can't handle it, but I still would like to replicate those sustained clocks and set it back once I upgrade my PSU to Titanium at double the system TDP next week.

The dillema I have right now is how do I get that sustained boost at 60°C back. I set the BIOS as it was before the BSOD and it just isn't happening. Power and temps are as if C states are enabled but they're not. Was it a fluke or something? What am I missing here?

A couple of things comes to mind:

First, you may have to repair your OS because "msedgewebview2" error most likely indicates the system is corrupted (resulted from bsod) Try standard procedure that can be found in internet, i.e. sfc scannow, then dism, and so on

Second, the core ranking showed by hwinfo could also be due to incorrect bios settings. Double check the CPPC and CPPC preferred cores are enabled.

That makes sense! After MOBO upgrade I reinstalled windows and one odd thing I noticed was that monitor would go to sleep during gameplay while AFK. This is unexpected behaviour and your reply confirms my suspicions. I somewhat disregarded them because I configure windows not to auto update and given that this is a fresh and fully updated version of windows I thought that maybe Microsoft decided to enforce ecological practices as last windows 10 update or something. Assumption is in deed a mother of all screw ups. Thanks!
