I've been running my current setup since 10.6 in 2010, using the iMac 11,1 system definition with Chameleon/Chimera. GA-P55A-UD4P board, i5-750 overclocked to 3.2GHz with turbo enabled. I'm using the edited DSDT for this board downloaded from this site.
I decided to try a Clover installation on a second SSD and after a rough start i've got it booting into 10.10.4 and running mostly fine (Turbo works, sleep and SpeedStep down doesn't)
But whenever I reboot from the Clover drive back to my "main" Chimera+10.9 installation, the VCore setting in my BIOS gets reset back to "Auto". Normally, I have it manually set to 1.375v as that seems to be the most stable value for my CPU, allowing it to turbo all the way up to 3.8GHz no problem. But with VCore at "Auto", my machine will usually lock up during or shortly after boot.
The strange part is that none of my other settings in the BIOS are altered, only the VCore is reset. Has anyone else ever seen an issue like this? Is booting with Clover allowing things to access the BIOS in a way Chimera wasn't, and if so, how do I prevent it from resetting?
Worst case scenario I'll just keep sticking with Chimera, but since Clover seems to be the wave of the future and doesn't require any kext rollbacks, I figured I'd give it a shot.
Clover config.plist is attached. I'm using the latest Clover r3241, installed to the EFI partition. I tried both SATA and BIOSBlockIO variants but they each exhibit the same behavior.
