Solved OC instability.... but why?

[HexerPsy]

Hi there!

I have a 5900X on a ASUS Strix X570-E gaming mobo with both a PBO2 overclock and a memory overclock (details in the screenshot).

Recently been playing Against the Storm which runs 4K 144Hz on the also OCed 3080Ti. However I would ALWAYS get a BSOD with WHEA uncorrectable error within 30min of gameplay.

 

This made me I stresstest again and again -- long story short, couldnt find the CPU OC or the memory to be unstable, but noticed I may have skipped some steps during my memory OC.

 

I went to the bios and set:
SOC Voltage: Auto -> 1.1 (Auto was 1.11~V)

VDDG CCD: Auto -> 1.05V (no info on its prior voltage)

VDDG IOD: Auto -> 1.05V

CLDO VDDP: Auto -> 0.95V

And now the game no longer crashes..... but why not?
I would love to learn why these settings would make such a difference, for what is probably an edge case within a game.

Maybe.... this would allow me to get the memory from 3733 to 3800 now.... tweaking fun for later.

Anyway, I would love to hear your theories!

Your manual set voltage might be slightly higher than what the auto setting did, on auto is could have also dropped too low to cause a crash.
