How to Fix Upgraded RAM from 8gb (2x4gb) to 16gb (2x8gb) and now Big Sur wont boot.
This mini-guide provides a structural approach to troubleshoot and fix the issue.
Prerequisites
- Confirm your hardware specifications (CPU, GPU, Motherboard).
- Ensure you have a bootable recovery USB and backup your EFI.
Fix Steps
- Boot with
-v keepsyms=1 debug=0x100to identify the exact kernel panic. - Validate your config.plist using ocvalidate.
- Ensure your EFI matches the Dortania guide specifications for your CPU generation.
Verification
- Reboot and verify if the functionality is restored and stable under typical usage.
Original Question:
My setup is separate drives on dualboot Mac and Windows. Using OpenCore 0.6.6
Tested my 16gb RAM on Windows' MemTest64 for 2 hours with zero errors and still going. So incompatible RAM is out of the question. RAM sticks are also seated properly. Reinstalled it one to many times.
I tried a different set of 16gb RAM sticks and still wont let me boot. Sadly I can no longer reinstall my 8gb set because I already sold it.
Is there a configuration where I can set the RAM to be able to make me boot into my Big Sur partition? Opencore works on the boot picker. But soon as I hit the Apple icon it gives me the "Your computer restarted because of a problem" and upon hitting Enter key it just sends me back to startup boot.
