How I resolved Valheim randomly crashing with the player log error "ERROR: SymGetSymFromAddr64, GetLastError: 'Attempt to access invalid address".

[nick]

Hey, i know it might be late but in hope that it'll solve somebody else problem i will let my experience here. I had a LOT of random crashes with "ERROR: SymGetSymFromAddr64, GetLastError: 'Attempt to access invalid address". Not only for Valheim but almost all my games were crashing at random, could be 5 min , could be 8 hours, ended up happening. I have the latest computer with a very decent build, intel i9 processor, geforce 4070, lots of ram.


Luckily for me I was able to video proof my vendor that it was a hardware issue because OCCT benchmark tests would fail so they help me free under guarantee. Tests that were failing are the basic CPU test and power test. Boy would the power test failed in a catastrophic way, leading to a BSOD immediately.


So, what was the problem? It wasn't Valheim or any other games, mofo INTEL cpu was the problem, they sold the i9 as a certain voltage but it is calculated like an insecure men giving away his penis length, so my BIOS (TUF gaming) was built around those magical fairytale numbers, and at a turning point, the cpu can't take it anymore and shuts down whatever it was running. So the solution is, my vendor told, a BIOS update especially for the processor putting back those number to what they should be. The basic BIOS update won't give that fix, i tried, it has to be that specific issue's bios update.


TLDR: If you are randomly crashing with invalid address, go download OCCT, if the POWER or CPU test fails (try it multiple time, sometime it works out of nowhere), you know you have that problem, go and search the BIOS fix for the intel voltage miscalculation thing.

If you find the exact name of the BIOS fix please post it there, i'm sure it'll help someone, i just went through 4 months of insane testing and a lot of anxiety thinking i just threw away thousands of dollar in a lemon computer.
