Question about Ryzen 9800X3D overheating and freezing PC before Event Viewer access.
Been trying to find a stable undervolt for my PC, going through the time to find a stable curve optimizer value on per-core setting. I've been following a PBO2 guide on youtube from a channel named Bosmang which worked really well when undervolting my 5800X. Unfortunately one of the methods used for finding out which core crashed/failed through logging WHEA errors on Event Viewer doesn't work on my 9800X3D as instead of my PC shutting off automatically on an unstable curve, my PC completely freezes until I manually shut it off myself which results in no log to see in the Event Viewer.
After using Prime95 which allowed me to find what cores to dial down on the undervolt before my PC freezes, I played a bit of the Monster Hunter Wilds beta which then froze my entire PC making me believe my curve wasn't stable. Went searching around for another alternative to Prime95 and found CoreCycler/Y-Cruncher, but even after running more tests to find another stable curve, I booted up Monster Hunter Wilds again and ran into another system freeze.
While it may just be the game causing this, I just want a stable undervolt that doesn't give me another system freeze. And I've been told I might have the worst luck of silicon lottery with the current curve setting I have being:
-16
-8
-16
-11
-9
-4
-18
-16
which I can assume is really low. Is there any way to fix the freezing on unstable settings and have my PC shut down automatically instead so I can at least see a WHEA error in Event Viewer?

It seems the issue might have been with the game and my particular SSD (Samsung QVO). After transferring it to an NVME boot drive, I ran the benchmark for over eight hours without any problems. I keep testing occasionally to confirm it's just my SSD.

Begin with no undervolting adjustments. Test work and game to check for stability without crashes or shutdowns. If further undervolting is needed, apply it gradually in tiny steps. Pause between each action, record observations, and avoid any other modifications. The goal is to identify the voltage levels where issues start.
I really wish I could at least record something in Event Viewer for reference. I don’t understand why my computer freezes under unstable undervolt conditions instead of powering down.
I just realized my motherboard has a 16-pin connector for the CPU, but I'm only using half of them. Could using all 16 pins potentially resolve the issue?
I've been attempting to lower my CPU voltage, spending considerable time searching for a reliable stable curve optimizer setting per core. I followed a PBO2 tutorial on YouTube from a channel called Bosmang, which proved effective for my 5800X. However, one of the techniques used to identify failing cores via WHEA errors in Event Viewer doesn't apply to my 9800X3D. Instead of automatic shutdown on an unstable curve, my PC would freeze completely until I manually powered it down, leaving no logs in Event Viewer. After using Prime95, which helped pinpoint cores to adjust without freezing, I tried playing a bit of Monster Hunter Wilds beta, which caused my whole system to freeze and made me doubt the stability of my curve. I searched for another tool but found CoreCycler/Y-Cruncher, which seemed more demanding. Even after further testing for a stable curve, I encountered another freeze while running the game.
Currently, this is the last stable curve I used before experiencing my final crash:
-16
-8
-16
-11
-9
-4
-18
-16
I was advised to check what Reliability Monitor records, but the only info I received was "Windows didn't shut down properly." I'm uncertain if this is due to unfortunate hardware issues or simply the low voltage setting compared to other 9800X models I see online. I'm hoping my PC can shut down automatically instead of freezing, so I can rely on WHEA logs for analysis.
Also, my motherboard features a 16-pin CPU power connector, and I'm only using 8 of them. While lowering voltage is meant to reduce power draw, could connecting all 16 pins to the PSU actually resolve my undervolting issue?
