Recently Upgraded to Alder Lake (12th Gen) CPU and Started Crashing, Fixed by Disabling E-Cores

This is just an informational post in case anyone happens to be crashing in the game. I had a Ryzen 3900X and had experienced no crashes in MO2, but when I upgraded to a 12700K my game began crashing every 15-45 minutes. I tried reseating the RAM and GPU, ran Memtest86 and other benchmarks to ensure my hardware was alright. I tried Windows 11, since that has a CPU scheduler meant for Alder Lake CPU's and still crashed there as well with Windows 10. I came across a post for another game where someone was saying they were crashing and disabling E-Cores helped them so I gave it a try, left MO2 running over night and after being in the game for 12 hours didn't crash at all.

I'm sure there's users with 12th gen Intels out there not crashing with E-Cores on, but I thought I'd post my experience and what worked for me on the off chance someone is having issues and is looking for things to try.

Im in the midsts of upgrading to the same cpu. Haven't quite assembled it all yet though. How did you go about disabling the e-cores?

It's a setting in the BIOS, but I imagine the name of it might vary depending on motherboard brand. For me, it was in the same OC settings area where you'd play with voltages for the CPU. I also highly recommend undervolting that CPU, I was able to maintain the same clocks and lower voltage whilst maintaining stability and it lowered temperatures by almost 20C (Using a Noctua NH-U12S heatsink)
