MNSiw Posted July 1, 2021 Share Posted July 1, 2021 With Windows 10 or 11 only setup it works perfect, never show any such error. Haven't tried dual boot. Now on Big Sur, it shows 'Real-Time Clock Power Loss (005)' error on boot. Usually it doesn't show this error on first boot after overnight power off. Already tried DisableRtcChecksum and rtcfx_exclude=00-FF with RTCMemoryFixup.kext Then I tried SSDT-AWAC.aml and SSDT-RTC0-RANGE-HEDT.aml, but is still the same.

SavageAUS Posted July 1, 2021 Share Posted July 1, 2021 Have you tried the registry edit for windows? RealTimeIsUniversal or something like that. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Not on dual boot, just Big Sur. On Windows it works perfect. Checked it with Windows 10 and Windows 11 only setup, no issue at all, it boots every single time without any error.
